Brake pad wear: Adjust the brake pads gap or replace motor brake failure 2. Brake spring break: Replace brake pads brake springs 3. serious oil: two brake pads clean, large hanging motor noise do not move heavy objects 1. Power voltage is too low: 2. capacitor voltage is normal to be damaged: Replace the capacitor is not completely disengage the brake pads 3: Adjust the brake pads gap three foot braking force is too small 1. pin slip : 2. Replace the brake band break: just replace the brake band 3. brake band wear: swap pin jack four big noise machine 1. poor lubrication: add a little oil 2. gear bearing damage: 3. Check the replacement gears or bearings are rotating body shell is not installed touch: Reinstall the small lifting machine, lifting machine, Jiangxi, Xinyu Xinyu lifting provided by Crane Co.
