Actuating the Thumb (Gripping/Clamping): This is its core function. The cylinder extends to close the thumb against the bucket, creating a powerful clamping force. This allows the excavator to securely pick up, hold, and manipulate irregularly shaped objects like rocks, logs, concrete debris, and scrap metal.
Releasing the Load (Opening): The cylinder retracts to open the thumb, releasing the gripped material in a precise and controlled manner for accurate placement.
Generating and Maintaining Clamping Force: The cylinder must generate sufficient force to securely hold heavy, dense materials without dropping them. It must also maintain this force during dynamic machine movements like lifting, swinging, and travelling.
This 378-5575 extension cylinder is used for cat machine.
