Reinforced upper thrust rod ball made of 20MnCr5 steel (hardened chromium-manganese steel) with an electrochemical coating.
Application
The lower ball joints serve as attachment points between the machine and the lifting arm hooks.
How to use
To install the ball joint, slide it onto its pin, which has a hole for inserting a safety pin. The safety pin makes it impossible for the lower ball joint to slip off the coupling pin, thus ensuring optimum security.
