3. Parking brake adjustment
3.1 Adjusting the clearance
(between brake shoe and drum)
1. Jack up the crane and keep the parking brake
lever disengaged by removing the connecting pin.
2. Rotate the brake drum. Align the adjustment hole
in the drum with the adjuster wheel for the
lining-drum clearance adjustment.
3. Insert the screwdriver through the adjustment hole
and rotate the adjuster wheel to expand the shoes
until the lining fits the drum (resistance is
encountered).
4. Then return the adjuster wheel by 8 notches. The
clearance between the lining and brake drum is
now adjusted to the standard clearance of 0.23
mm (0.009 in).
3.2 Connecting the parking brake and the brake
chamber
1. Place the parking brake lever in the zero-point
position (middle of lever play).
2. While the parking brake is released, the brake
chamber is expanded to its stroke end by the
pressurized air, connect the chamber and brake
lever using material X (end).
3. After connecting, check for any friction between
the drum and lining. Then lock the rod with
material Y (nut).
