Hydraulic Lift Cylinder Clearance When Installing Roll-Off Hoist

Recently we have learned of a pair of lift cylinders being destroyed because of mounting bracket interference when the Roll-off Hoist was raised.

Precautions must be taken to assure clearances for fenders, tarper mounting brackets, bumpers, etc. before and after they are installed.  The hoist must be raised to its full dumping height either with its hydraulics or an overhead lifting crane to establish the amount of needed clearance.  See drawing below.
