What to do if the BRADEN CH280 brake won't hold a load in neutral?

  Deanna OlsonAug 5, 2025
  If the brake isn't holding a load with the control lever in neutral, excessive system back pressure acting on the brake release port may be the cause. The solution is the same as Remedy 2 of Trouble B2. Also, worn or damaged brake discs may be the reason. You should follow Remedy 3 of Trouble A3. Slipping of the brake clutch could also be the reason. In that case, drain the old gear oil and flush the hoist with solvent, then thoroughly drain the solvent and refill the hoist with the recommended planetary gear oil. The brake clutch itself may also be damaged or worn, requiring disassembly and inspection.

How to fix a BRADEN Winches hoist that won't raise the rated load?
- J
  Janet SantiagoAug 9, 2025
  If the hoist won't raise the rated load, it might be mounted on an uneven or flexible surface, causing distortion and binding. Reinforce the mounting surface and use shims to level the hoist. First loosen, then evenly retighten all hoist mounting bolts to the recommended torque. Alternatively, the system relief valve might be set too low. Check the relief pressure by installing an accurate 0–4,000 PSI gauge into the inlet port of the brake valve.

Why is my BRADEN Winches hoist not raising the rated load?
- B
  Bradley MillerAug 13, 2025
  Several factors can cause a hoist to fail to raise the rated load. Be certain the hydraulic system temperature is not more than 180°F (82°C). Excessive hydraulic oil temperatures increase motor internal leakage and reduce motor performance. Follow the same remedies for Trouble D1 and D2. The hoist line pull rating is based on the first layer of wire rope. Follow the same remedies for Trouble E2. Inefficient rigging and sheaves may also be the cause. Refer to hoist performance charts for additional information. Perform rigging service as recommended by the crane manufacturer.

What causes a BRADEN Winches hoist to chatter when raising a load?

  Chattering during lifting can be caused by the same issues as D2, so apply the remedies for Trouble D2. It could also be due to low hydraulic oil flow to the motor, so apply the remedies for Trouble E2. Also, the controls may be operated too quickly. If so, conduct operator training as required.
