Structure of brake is shown in the drawing. After the
truck has been used for some time, the braking
performance will decline with the wearing of brake plate,
or the brake plate locks and cannot release the brake,
then the brake clearance needs adjustment. As shown in
the drawing, under the braked condition, first measure
the gap between the brake plate and the magnetic steel
with a feeler gauge. If the gap is greater than 0.5mm, the
clearance needs adjustment. Before adjustment, first
wipe out dirt and dust on the friction plate. When
adjusting, first release the connecting screw, adjust the
length of adjusting screw 1, and then, fasten the
fastening screw. After adjustment, the clearance between
brake plate and magnetic steel should be between 0.2-0.3mm. Pay attention to adjust the three adjusting
screws evenly to make the clearance between brake plate and magnetic steel spread evenly around. After
adjustment, connect the brake with 24V DC power, and crisp sounds of suction shall be heard.
