ABSTRACT:
This is a unique mast roller as is used by lift trucks, and the like. It is characterized by a number of roller assemblies which are both removable and adjustable to compensate for variations in spacing between channel track members brought about by manufacture and by wear. Shims of different sizes can be inserted to compensate for this variation and said shims are of a configuration to allow fastening members to be removably installed. The plates supporting the rollers in this assembly are of a construction so as to provide adequate bearing surfaces for side movement between the channel guide members.
