8.1.2 CARRIAGE
The carriage has end rollers that roll along the inside of the inner channel, each installed on the end
roller shaft by bearings. The end roller shafts are welded to the carriage. The upper end rollers are shim-
adjusted while the lower end rollers are secured to the shafts with snap rings.
Longitudinal load is sustained by the end rollers. When the forks are raised to the maximum height,
the upper end rollers emerge from the mast top. Transverse load is sustained by the lower side-rollers.
