Rotating grapple is a powerful and versatile excavator attachment, but to maximize its performance, correct installation is essential.
Follow this step-by-step guide to ensure safe, efficient, and professional installation.
Check Compatibility
Before starting, inspect both the grapple and excavator to ensure they are compatible in terms of size, hydraulic flow, and connection type.
-
Confirm attachment weight is suitable for your excavator’s lifting capacity.
-
Check quick hitch or pin dimensions match the grapple.
Convert Hydraulic Control System
For rotating grapples, the hydraulic control system may need to be modified.
-
Refit hydraulic control to electronic control to match grapple operation requirements.
-
Connect the three pilot foot valve pipes to the pilot valve.
-
Install the pilot valve circuit to enable smooth grapple movement.
Upgrade Joysticks
Precise control is key for grapple operation.
-
Replace standard joysticks with ones that include extra control switches.
-
Install the joystick wiring and connect it to the control circuit.
Install Circuit & Hydraulic Lines
Route and secure wiring and hoses carefully:
-
Install the electric circuit along the boom and arm of the excavator.
-
Lay hydraulic oil pipes along the same path, ensuring they are protected from friction and damage.
Connect the Rotating Grapple
Finally, attach the rotating grapple securely to the excavator’s quick hitch or pin connection.
-
Connect all hydraulic and electrical lines.
-
Test all functions to confirm smooth rotation, opening, and closing before operating in real conditions.
Tips for Professional Installation
-
Always follow the manufacturer’s torque specifications.
-
Use protective sleeves for hoses to avoid wear.
-
Test at low hydraulic pressure first to prevent sudden movement.
-
Ensure all connections are leak-free before use.
With correct installation, your rotating grapple will deliver optimal performance and a longer service life—making every lifting, sorting, and material-handling task safer and more efficient.
