Why does my BRADEN Industrial Electrical winch run hot?

  Christopher WilliamsAug 4, 2025
  If your BRADEN Industrial Electrical winch is running hot, it could be due to several factors. It might be mounted on an uneven or flexible surface, causing distortion and binding of the gear train. Ensure the mounting surface is reinforced and level the winch with shims if needed. Also, ensure that the hydraulic system temperature is not more than 180 degrees F, thoroughly clean the exterior and flush the interior. Excessively worn or damaged internal winch parts can also cause overheating. Disassemble the winch to inspect and replace any worn parts.

What to do if BRADEN Industrial Electrical winch brake will not hold a load?

  If the brake on your BRADEN Industrial Electrical winch won't hold a load with the control lever in neutral, excessive system back pressure acting on the brake release port could be the issue. Inspect the hydraulic system for a restriction in the return line from the control valve to the reservoir, and ensure the control valve and plumbing are properly sized to the winch motor. Also, worn or damaged brake discs can cause the brake to fail. Disassemble the brake to inspect the brake discs. Lastly, brake clutch slippage can also cause the issue. Drain the old gear oil and flush the winch with solvent, then thoroughly drain the solvent and refill the winch with the recommended planetary gear oil. The brake clutch itself may be damaged or worn, requiring disassembly and inspection.

Why does my BRADEN Industrial Electrical winch chatter while raising a load?
- D
  Derrick HernandezAug 13, 2025
  If your BRADEN Industrial Electrical winch chatters while raising a load, it could be due to a few reasons. The winch may be mounted on an uneven or flexible surface, causing distortion of the winch base and binding of the gear train. Reinforce the mounting surface, and if necessary, use shim stock to level the winch. Also, the hydraulic oil flow to the motor may be too low. Inspect the hydraulic system for a restriction in the return line from the control valve to the reservoir, and ensure the control valve and plumbing are properly sized to winch motor. Finally, the controls might be operated too quickly, so conduct operator training as required.

What to do if my BRADEN Industrial Electrical winch will not hoist the rated load?
- M
  michele10Aug 17, 2025
  If your BRADEN Industrial Electrical winch isn't hoisting the rated load, it could be due to a couple of reasons. The winch may be mounted on an uneven or flexible surface, causing distortion of the winch base and binding of the gear train. Reinforce the mounting surface and use shim stock to level the winch if necessary. Alternatively, the system relief valve may be set too low. Install an accurate 0-4000 psi gauge into the inlet port of the brake valve to check the relief pressure.
