Abstract: A device for pulling a trip cable in order to trip a lever with the cable. The device is particularly suited for pulling the trip levers of the bunk stake assemblies of logging trucks. Two of the present devices can be used together to trip both a front and a rear bunk assembly. A spool, which can be mounted on the front end of a loader, is used to store the cable when it is not in use. A large coil spring is used to rotate the spool in order to wind the cable thereon after tripping takes place. A device adjacent the spool is used to grip the cable when one end of the cable is connected to the lever to be tripped. A hydraulic cylinder and piston mechanism is preferably provided for pulling the cable with the gripping means a distance sufficient to trip the lever and disconnect the cable from the lever. After tripping takes place, the spring automatically winds the cable onto the spool.
