Operator complained the deadman button wasn’t releasing. 
The bell crank that operates the deadman switch pin broke. The temporary fix was to remove the top of the joystick and button and manually lift the deadman lock pin. When the technician was able to arrive on site a T85 joystick was used in place of the MRH joystick until replacement parts were made. The Deadman contact is different from a T85 stick and so the contact switch needed to be swapped.
Potain has switched design on the replacement joysticks, so a new bell crank was made
and reinstalled into the old joystick and reinstalled into the crane.
