8.1.2 Lift bracket
The lift bracket moves up and down smoothly along the channel of the inner mast
with main rollers. The main roller is fixed on the axis of the main roller by snap ring. And
the axis of the main roller is welded on the lift bracket. But the side roller is assembled on
the lift bracket with bolts. The moving along inner mast wind plate can be adjusted by
shim. To prevent the clearance when moving, make two immovable side rollers move
along the outside of inner mast wind plate. Main rollers sustain the longitudinal loads. And
side roller sustains the transverse loads. When forks reach the maximum height, the
upper pair of main rollers will come out from the top of the inner mast. (Fig. 8-3, Fig. 8-4)
