FIELD: material handling; electric loaders with lifts. SUBSTANCE: lift has at least one frame and carriage installed for vertical travel along frame uprights on bearings whose inner races are installed for travel along bearing axle by means of adjustable threaded fastener. Made in carriage check are at least two through holes whose axes are parallel to bearing axis. Fitted in holes are rods thrusting by one end against end face surface of bearing inner race and by other end against end face surface of washer located on fastener, for instance, on screw. Fastener is arranged at side opposite to side of contact of axle and carriage cheek. Clearance between bearing and upright is adjusted by tightening the fastener. When fastener is being tightened, washer moves along axle and shifts the rods, thus decreasing the clearance. With clearance adjusted, washer can be fixed relative to fastener by means of lockwasher.
