Why is my Ingersoll-Rand Winch not lifting or pulling the load?
- C
  Corey YoungAug 21, 2025
  If your Ingersoll-Rand Winch doesn't lift or pull the load, it could be due to several reasons. First, the winch might be overloaded; try reducing the load to stay within the rated capacity. Second, there might be insufficient air supply. Make sure the air supply pressure and volume at the winch inlet meet the requirements. Also, clean the air line filter. Finally, the motor may be damaged. In this case, you should examine all parts and replace any that are worn or damaged.

  If your Ingersoll-Rand winch is not operating, there are a few things you can check. First, make sure that there is an adequate air supply to the winch by checking the air supply line connections and hoses, and ensure that the air pressure at the winch inlet is at least 90 psig (6.3 bar/630 kPa) at rated volume. Second, ensure that the winch is not overloaded, and reduce the load if necessary. Finally, make sure the drum brake is released.

What to do if throttle lever moves but Ingersoll-Rand Winch doesn't operate?
- L
  Linda HodgeAug 25, 2025
  If the throttle (or pendant) lever moves but the Ingersoll-Rand winch does not operate, it could be due to a damaged motor. Disassemble and clean the motor, replacing any broken or damaged parts. Another possibility is insufficient air supply. Ensure the air pressure at the winch inlet is at least 90 psig (6.3 bar/630 kPa) at rated volume, and clean the air line filter.

Why does the motor of my Ingersoll-Rand Winch run hot or make noise?
- J
  James FloresAug 27, 2025
  If the motor of your Ingersoll-Rand Winch runs hot or makes excessive noise, there are several potential causes. Check the oil level in the motor and adjust as needed. The lubrication may be improper, so replace the oil with the type recommended and set the lubricator to provide a minimum of 6 drops per minute, also check the oil level in lubricator. There might be water in the oil, so drain and refill with oil, and operate the winch slowly in both directions. Finally, a piston or connecting rod might be damaged or broken, requiring you to disassemble and repair the motor.

What to do if load continues to move when Ingersoll-Rand Winch is stopped?
- M
  muellerjessicaAug 28, 2025
  If the load continues to move when the Ingersoll-Rand winch is stopped, it's likely that the drum brake is slipping. You should check the drum brake adjustment and inspect the brake band lining for wear.

Why is my Ingersoll-Rand Winch running slow?
- C
  castromichaelAug 29, 2025
  If your Ingersoll-Rand winch runs slow, it could be due to improper hose or fitting sizes. Check the fittings, connections, and hoses for the correct size and length, replacing any parts that may be restricting airflow. Also, inspect the air line filter. Another possibility is that the motor may be damaged, so you should inspect all parts and replace any that are worn or damaged.

What causes the brake cylinder of Ingersoll-Rand Winches not to release?
- J
  Jasmine MoralesAug 31, 2025
  If the brake cylinder of your Ingersoll-Rand Winch will not release, it could be due to a few reasons. The drum brake might be out of adjustment, so adjust it to maintain the correct cylinder stroke. The cylinder seals could be damaged; if air is escaping from the cylinder breather when you try to release the brake, replace or repair the cylinder. The filter in the air supply might be dirty, so clean or replace it. Finally, the exhaust port might be plugged; clear any foreign material out of the exhaust port, ensuring air exhausts when the control valve handle is in neutral.

How to prevent air lines from freezing on Ingersoll-Rand Winches?
- N
  Nicole RomeroSep 2, 2025
  If the air lines of your Ingersoll-Rand Winch are freezing, it's likely due to water in the air supply. Install or drain air system moisture traps, moisture collecting air receivers, and compressor aftercoolers. After these actions, disconnect the lines at the winch inlet and purge them with clean, dry air or nitrogen before reattaching and operating the winch.

What to do if load continues to move when Ingersoll-Rand BU7A Winches are stopped?
- V
  Vicki WilliamsSep 3, 2025
  If the load continues to move after stopping your Ingersoll-Rand Winches, it could be due to a slipping brake, an overload, or sticky winch motor controls. You should check the brake band lining wear. Also, reduce the load to stay within the rated capacity. Finally, make sure the pendant or throttle levers spring back to the neutral position when you release them.

  henryanitaSep 5, 2025
  If your Ingersoll-Rand Winches won't operate, first check the air supply line connections and hoses to ensure sufficient air. If the winch is overloaded, reduce the load. Remove any shipping plugs in the valve and motor exhaust ports. If the drum brake doesn't release, disengage the manual band brake. If the motor is damaged, disassemble and clean it, replacing any broken parts. Check for air leaks in hoses and fittings, tightening or replacing as needed. Finally, address frozen air lines by installing or draining air system moisture traps and purging the lines with clean, dry air or nitrogen.
