GalFab, Inc. received a request to make the Rear Roller Shaft removable without using a torch and welder from one of our customers. With this information we redesigned the shaft and all units produced after August 20, 2012 will have this change. This shaft change will also work on the units that were produced before this date.
Galfab, Inc. has a smart numbering system to establish their Roll-off hoist Models

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.
