Frequently Asked Questions – Rotating Hydraulic Grapple RHG400
What is a rotating hydraulic grapple like the RHG400 used for?
A rotating hydraulic grapple is used for a variety of material handling tasks, including sorting, loading, and moving debris, logs, rocks, and scrap metal. Its ability to rotate 360 degrees makes it ideal for precise positioning and manipulation of materials in construction, demolition, forestry, and recycling applications.
How does a rotating hydraulic grapple work?
A rotating hydraulic grapple operates by using powerful hydraulic cylinders to open and close the jaws, allowing it to grip materials securely. The integrated hydraulic rotator enables the grapple to rotate 360 degrees continuously, providing exceptional maneuverability and control. This rotation is controlled by the excavator’s hydraulic system, allowing the operator to position materials accurately.
Can a rotating hydraulic grapple be used with any excavator?
Most rotating hydraulic grapples are designed to be compatible with a wide range of excavators. However, it’s essential to ensure that the specific model of the grapple matches the size and hydraulic capacity of your excavator. Check the manufacturer’s specifications to confirm compatibility.
What maintenance is required for a rotating hydraulic grapple?
Regular maintenance of a rotating hydraulic grapple includes:
- Inspecting and lubricating all moving parts and joints.
