Frequently Asked Questions
Use these questions to identify the correct HAWK product family and prepare the information needed for an accurate recommendation.
What equipment and systems does HAWK Excavator provide?
HAWK provides long reach excavator packages, amphibious undercarriages, HAWK Vision RTK GPS positioning systems, modular sectional barges and specialized excavator attachments. These systems support excavation, dredging, demolition, marine construction, wetland work and material handling. HAWK can help match the equipment to the excavator, application, required working envelope and jobsite conditions.
Does HAWK sell complete excavators or conversion packages?
HAWK’s core offering is specialized equipment that upgrades or equips an excavator for a particular application. A long reach package or amphibious undercarriage is configured for the customer’s excavator rather than being the base excavator itself. Rental availability may include configured equipment, so customers should confirm the exact machine and components included in a quote.
Which HAWK solution is right for my project?
The correct solution depends on the access problem. Choose a long reach package when the excavator must work farther away, deeper or over an obstacle. Choose an amphibious undercarriage for soft wetlands, marshes and shallow-water access. Use a sectional barge when the excavator needs a floating work platform, and use HAWK Vision when the operator needs precise position information for a bucket or pump that cannot be seen.
Can HAWK equipment fit my existing excavator?
HAWK equipment can be configured for many common excavator brands and models, but compatibility is not universal. HAWK must review the machine model, serial or configuration information, operating weight, pin dimensions, hydraulic capacity, planned attachment and required working envelope before confirming fit. A model name alone is not enough for final engineering approval.
What information does HAWK need to confirm compatibility?
Provide the excavator manufacturer, model, year or serial information, operating weight, boom and stick configuration, hydraulic flow and pressure, coupler or pin dimensions, planned bucket or tool, required reach or depth, material being handled, ground or water conditions, project location and schedule. Photos, lift charts, site drawings and bathymetric information may also be useful for specialized projects.
Can HAWK equipment be rented or purchased?
HAWK offers rental and purchase options for its equipment, subject to the product, configuration and current availability. Renting can make sense for a defined project or an occasional specialized need. Purchasing can be more practical when the equipment will be used repeatedly or must remain configured for ongoing work. Ask HAWK to compare the available paths for your schedule and application.

Long Reach Excavator Packages
These questions help buyers choose a working reach, understand capacity tradeoffs and confirm what must be engineered with the excavator.
What is a long reach excavator package?
A long reach excavator package replaces the standard front arrangement with a longer, matched boom-and-stick system. It allows an excavator to work at greater horizontal reach, digging depth or height while remaining positioned farther from the work area. Long reach configurations are commonly used for dredging, canal and pond maintenance, slope work, deep excavation, demolition and work across obstacles.
What is included in a HAWK long reach package?
A HAWK long reach package is configured around a matched boom, arm or stick, bucket linkage, pins, hydraulic components and bucket or other approved tool. Depending on the application, it may also include a bucket, cylinders, auxiliary hydraulic plumbing, slurry-hose brackets and an additional counterweight. The quotation and approved configuration should identify every included and optional component.
What is the difference between a standard excavator and a long reach excavator?
A standard excavator is designed to balance digging force, lifting capacity and reach for general work. A long reach excavator extends the working envelope so the machine can dig deeper or work farther away, but the additional radius changes leverage, stability and allowable tool or material weight. The long reach configuration must therefore be matched to the excavator and application rather than treated as a simple length extension.
What is the difference between long reach and high-reach demolition equipment?
Long reach equipment is commonly configured for horizontal reach and digging depth in dredging, slope, canal and excavation work. High-reach demolition equipment is designed around controlled work at elevation and may require different boom geometry, guarding, tool selection and safety systems. HAWK should review the exact demolition height, structure, tool and machine before recommending a configuration.
How much additional reach can a HAWK package provide?
The available reach depends on the excavator model, machine weight, boom-and-stick geometry, attachment weight, required capacity and stability review. HAWK offers multiple long reach configurations, but the longest physical option is not automatically the best working option. The correct target is usable reach with the required tool and load, not an unloaded headline dimension.
How is the correct boom and stick length selected?
HAWK selects the boom-and-stick configuration by reviewing the required horizontal reach, digging depth or working height together with the excavator, attachment, material, working radius, ground conditions and stability requirements. Site drawings or a target work envelope are more useful than simply requesting the longest available arm. The final recommendation should include the operating-range information for the approved configuration.
What is the difference between maximum reach and effective working reach?
Maximum reach is the farthest point the attachment can physically extend. Effective working reach is the distance at which the excavator can safely perform the intended task with the selected bucket, tool and material load. Because capacity generally decreases as the working radius increases, effective reach is the more important planning measurement.
How does a longer boom affect bucket capacity, digging force and lifting capacity?
Increasing reach increases leverage on the boom, stick, upper structure and undercarriage. As a result, allowable bucket size, tool weight, digging force and lifting capacity may be lower than with the standard front. HAWK must evaluate the complete configuration, including the loaded bucket or attachment, rather than applying the standard excavator ratings to the long reach setup.
Does a long reach excavator require an additional counterweight?
Some long reach configurations require an additional or revised counterweight to support stability, while others may not. The answer depends on the excavator, working radius, front weight, attachment, material and undercarriage. A counterweight should never be selected by reach length alone; it must be part of the approved machine-and-attachment configuration.
Which attachments can be used with a long reach excavator?
Long reach excavators may use approved digging buckets, clamshell buckets, grapples, hydraulic breakers, thumbs, dredge pumps and other tools. Compatibility depends on tool weight, center of gravity, hydraulic demand, coupler or pin geometry and the capacity available at the intended working radius. HAWK should approve the attachment as part of the long reach configuration.
Can a long reach package be removed, transported and changed back to a standard boom?
A long reach package can generally be removed so the excavator can be returned to another approved front configuration. Changeover time and transportation requirements depend on the machine, package, connection points, lifting equipment and site access. Some HAWK long reach systems are designed with a low folding profile for transportation, but the exact mobilization plan should be confirmed for the selected model.

Send HAWK your excavator model, target reach or depth, planned attachment and material. We will help identify the configuration that fits the work.
Amphibious Excavator Undercarriages
These answers address terrain access, buoyancy, stability and the configuration details that must be reviewed before an amphibious system is selected.
What is an amphibious excavator undercarriage?
An amphibious excavator undercarriage replaces the standard undercarriage with a wider, buoyant pontoon-and-track system designed for soft, wet and low-bearing-capacity terrain. It can improve access in marshes, swamps, wetlands, mud and shallow-water environments where a conventional excavator may sink or lose mobility.
Does an amphibious excavator actually float?
The sealed pontoons provide buoyancy, but “amphibious” does not mean every configuration is approved to work unsupported in open water. Stability depends on the excavator, boom, attachment, load, water depth, current, wind, bottom conditions and any supplementary pontoons or spuds. HAWK must approve the complete configuration and intended operating conditions.
What ground and water conditions are suitable for an amphibious excavator?
Amphibious undercarriages are commonly used in marshes, swamps, wetlands, saturated soil, mud flats, canals, ponds and shallow-water projects. They are not automatically suitable for deep water, strong currents, steep transitions, rocky ground or every protected wetland. Site access, bottom strength, water variation and environmental requirements should be reviewed before mobilization.
What is the maximum working-water depth for an amphibious excavator?
There is no single safe water-depth limit for every amphibious excavator. The allowable depth depends on the undercarriage model, excavator weight, boom and attachment, load, bottom support, water movement and whether supplementary pontoons and spuds are used. Provide HAWK with normal and maximum water depth, expected variation and bottom conditions for a configuration-specific review.
When are supplementary pontoons and spuds needed?
Supplementary pontoons increase platform width and buoyancy, while spuds can provide additional positioning and stability in appropriate bottom conditions. They may be required when the machine works in deeper water or with a more demanding reach and attachment configuration. They do not make every water condition safe, and their use must be part of the approved operating plan.
Which excavators can use a HAWK amphibious undercarriage?
HAWK can configure amphibious undercarriages for multiple excavator brands and machine classes, but the undercarriage must be matched to the exact excavator and application. HAWK should verify machine weight, upper-structure dimensions, mounting interface, center of gravity, boom configuration, attachment and intended operating environment before confirming compatibility.
How does an amphibious undercarriage improve ground pressure and stability?
The wider track-and-pontoon footprint spreads machine weight over a larger area, which can reduce ground pressure and improve mobility on weak or saturated surfaces. Stability still changes with boom direction, working radius, attachment and load. Low ground pressure is an access advantage—not permission to ignore the machine’s approved working limits.
Can a long reach package be used with an amphibious undercarriage?
Yes, a long reach package may be combined with an amphibious undercarriage when the complete system is engineered for the excavator and work. The longer working radius increases overturning demand, so the boom, counterweight, pontoons, supplementary pontoons, spuds, attachment and load must be evaluated together.
How is an amphibious undercarriage transported, operated and maintained?
Transportation and assembly depend on the undercarriage width, pontoon arrangement, machine class and route restrictions. Operators need configuration-specific instruction before working in wet terrain or water. Routine care includes inspecting pontoon integrity, track components, wear surfaces, fasteners and hydraulic systems and following the HAWK manual for the exact model.
Confirm the Undercarriage for Your Site
Share the excavator model, water depths, bottom conditions, planned reach and attachment so HAWK can review the complete amphibious configuration.
HAWK Vision RTK GPS
These answers explain what HAWK Vision measures, how it supports underwater work and what must be confirmed for accurate integration.
What is HAWK Vision?
HAWK Vision is an RTK GNSS positioning system for excavation and dredging equipment. It helps the operator monitor the position of a bucket, clamshell, dredge pump or other tracked tool, including work below the waterline where the tool cannot be seen directly. The system is intended to improve control of the work area and reduce avoidable over-digging or under-digging.
How does HAWK Vision track a bucket or pump underwater?
HAWK Vision uses positioning receivers, machine sensors, correction data and software to calculate the location of the excavator and tracked attachment. The operator sees the tool position relative to the project information on an in-cab display. RTK radio or cellular signals do not need to travel through the water because the system calculates the submerged tool position from the machine geometry and sensors above water.
How accurate is HAWK Vision?
HAWK Vision is designed for centimeter-level positioning when the system is correctly installed and calibrated and receives reliable satellite and correction data. Actual project accuracy can be affected by survey control, calibration, sensor installation, satellite visibility, multipath, correction age, communications and the quality of the design surface. Project tolerances should be confirmed during system setup.
What is the difference between GPS, GNSS and RTK?
GPS is one satellite navigation constellation. GNSS is the broader term for satellite positioning systems that may use multiple constellations. RTK is a correction method that uses a known reference source to reduce positioning error in real time. HAWK Vision combines GNSS positioning, RTK corrections, machine sensors and software for excavation and dredging guidance.
What equipment is included with HAWK Vision?
The required components depend on the machine and project, but a HAWK Vision configuration may include GNSS receivers, machine or boom sensors, an in-cab display, software, communications hardware, mounting components and a base-station or correction-source solution. The proposal should list the hardware, software, services, subscriptions and optional components included.
Does HAWK Vision work for hydraulic and mechanical dredging?
Yes. HAWK Vision can support mechanical dredging with buckets or clamshells and hydraulic dredging with a pump or suction head, provided the tracked tool and machine geometry are correctly configured. The project setup should identify the tool reference point, survey control, design surface and reporting requirements.
Is HAWK Vision compatible with dredging and survey software?
HAWK Vision is presented as compatible with established dredging workflows, including HYPACK and DREDGEPACK. File formats, licenses, correction services and data exchange requirements should be confirmed for the customer’s software version and project workflow before purchase. HAWK should also confirm how design surfaces, progress information and as-built data will be handled.
What installation, calibration, training and connectivity does HAWK Vision require?
The system must be mounted, measured and calibrated to the specific excavator and attachment before production work. Operators and project personnel should be trained on status indicators, correction quality, project files and loss-of-correction procedures. Connectivity options depend on the correction source and site; the operating plan should define what the crew does if corrections or communications are interrupted.

Modular Sectional Barges
These questions help project teams compare a floating platform with an amphibious undercarriage and prepare the loading information needed for proper sizing.
What is a modular sectional barge?
A modular sectional barge is a floating work platform assembled from interlocking buoyant sections. The sections can be transported separately and arranged to support dredging, excavation, marine construction, material handling or access equipment. Platform size and arrangement must be designed around the equipment load, working loads, water conditions and required freeboard and stability.
When should I use a sectional barge instead of an amphibious undercarriage?
Use an amphibious undercarriage when the excavator must travel across soft ground, marsh or appropriate shallow-water conditions. Use a sectional barge when the excavator or other equipment needs a floating work platform. Water depth, bottom conditions, travel requirements, current, mobilization and equipment loads determine which approach is more suitable.
How are sectional barge size and allowable load capacity determined?
Barge sizing must account for the excavator or equipment weight, counterweight, boom and attachment, fuel, personnel, stored materials, dynamic working loads, load position, freeboard and environmental conditions. The operating weight alone is not sufficient. HAWK needs the complete equipment configuration and intended platform use before recommending the number and arrangement of sections.
Can a sectional barge support an excavator with a long reach package?
A sectional barge can be configured to support an excavator with a long reach package when the platform, excavator and working envelope are evaluated as one system. The long working radius creates significant shifting loads, so platform dimensions, equipment position, anchoring or spuds, freeboard and operating limits must be established for the approved configuration.
How are sectional barges transported, assembled and expanded?
Individual sections are designed for truck or container transport and are connected at the jobsite to form the working platform. Assembly time and lifting requirements depend on the number of sections, connection system, access and support equipment. Additional sections may be added when the resulting configuration is reviewed for the new load and application.
What propulsion, anchoring and rental options are available for sectional barges?
Available options depend on platform configuration and project conditions and may include marine propulsion, winches, anchors or spuds. HAWK also offers rental and purchase paths subject to configuration and availability. The proposal should clearly identify included sections, connection hardware, access equipment, propulsion or positioning components, mobilization responsibilities and operating limitations.
Size the Platform Around the Work
Provide the equipment configuration, working loads, water conditions and project access details so HAWK can recommend a platform arrangement.
Excavator Attachments
These answers help buyers match a tool to the excavator, hydraulics, material and working configuration.
What excavator attachments does HAWK offer?
HAWK offers equipment for digging, dredging, demolition, processing and material handling, including buckets, clamshell buckets, grapples, breaker hammers, thumbs, quick couplers and dredge pump options. Availability and suitability depend on the excavator, carrier configuration and application.
How do I match an attachment to my excavator?
Match the attachment by more than machine weight. HAWK should review the excavator model, pin or coupler dimensions, hydraulic flow and pressure, return-line requirements, electrical needs, tool weight, center of gravity, material, duty cycle and planned working radius. Long reach and amphibious configurations may reduce the attachment weight or load that can be used safely.
Can my existing hydraulic connections and coupler be used?
Existing hydraulics or a quick coupler may be usable when the dimensions, pressure, flow, return path, controls and attachment requirements match. HAWK must verify the interface before the equipment is ordered. Adapters can change tool offset and working load, so their weight and geometry should be included in the configuration review.
Which bucket, grapple, breaker or dredge pump is right for my application?
Choose the tool by the material and task. Digging buckets suit excavation; clamshell buckets support vertical digging and material handling; grapples handle irregular material; breakers fracture rock or concrete; and dredge pumps move sediment through a discharge line. Material density, particle size, production target, working radius and hydraulic requirements determine the correct size and configuration.
Match the Tool to the Machine and Material
Send the excavator model, hydraulic information, material and production goal so HAWK can help narrow the attachment options.
Rental, Purchase, Installation and Support
These questions address the commercial and deployment decisions buyers need before requesting a final proposal.
How much does HAWK equipment cost?
Pricing depends on the excavator, product family, configuration, attachments, optional components, rental duration, availability, freight, installation and support requirements. Because specialized equipment must be matched to the machine and job, HAWK provides project-specific pricing rather than one universal price. A complete inquiry produces a more accurate quote and fewer later changes.
Should I rent or purchase HAWK equipment?
Renting is usually more attractive for a defined project, occasional use or a need that may change from job to job. Purchasing may provide better long-term value for repeated use, fleet standardization or continuous availability. Compare project duration, expected utilization, mobilization, storage, maintenance, financing and future work rather than deciding on monthly cost alone.
What information is needed for an accurate quote?
Provide the excavator make, model and configuration; target reach, depth or working height; attachment or tool; material; site and water conditions; project location; schedule; rental or purchase preference; and required installation or training. Include drawings, lift charts, photos, surveys or equipment data when available. HAWK may request additional dimensions before final approval.
What are the typical lead times and delivery options?
Lead time depends on product type, engineering, customization, inventory, rental availability, manufacturing and transportation. Delivery timing should be confirmed in the written quote for the exact configuration. Customers should also plan for permits, route restrictions, cranes or lifting equipment, assembly space and site readiness before the equipment arrives.
Does HAWK offer equipment financing?
Financing options may be available for qualified customers and eligible equipment. Terms, approval, documentation and availability depend on the financing provider and transaction. Customers should compare financing with rental, rent-to-own if offered for the selected equipment, and direct purchase based on expected utilization and cash-flow needs.
What warranty, parts, training and support does HAWK provide?
Warranty coverage depends on the product and purchase documents, so the written quotation and warranty terms should control. HAWK provides technical support and stocks replacement components for supported equipment. Installation, commissioning, operator training and field service should be confirmed in the proposal because the required level varies by product, project and location.
