DLC DLB350A Brake Winches

Product Information

The Brake Winches (DLB800A, DLB350A, DLB350AG, DLB800AG, DLB1200A, DLB1200AG, DLB1500A, DLB1500AG, DLB2000AG, DLB2500A) are manufactured by Dutton-Lainson Company, a company that has been in operation since 1886. The product is made in the U.S.A. The winches are designed to provide reliable and safe operation for various applications.

Important Safety Information

  • Read the instructions carefully before attempting to install, operate, or service the winch.
  • Failure to comply with the instructions could result in serious or fatal injury.
  • Retain these instructions for future reference.

Product Usage Instructions

  1. Before installation, ensure that the drive shaft produces a clicking noise when turned clockwise. Install the spring and locknut on the end of the drive shaft as shown on the parts drawing. Do not alter or remove these parts as they provide important fail-safe features.
  2. Ensure sufficient load is applied to the cable to overcome internal resistance and operate the brake properly. Turning the crank handle counterclockwise without sufficient load will only remove the handle.
  3. When mounting the winch, use three 3/8 bolts (M10), washers, and lock washers. For capacities of 1500 lb/680 kg or greater, use Grade 8 bolts. Using fewer bolts or alternate locations may result in damage to the winch base and malfunction.
  4. Attach the cable or rope as shown in the provided sketch.
  5. Never put the winch in freewheel mode if there is any potential load on the cable. Engage the lockout lever to prevent the winch from stopping in case a load is accidentally applied.
  6. Periodically inspect the winch for preventive maintenance. Check at least once annually and more frequently if exposed to a dirty or wet environment. Grease gears, reel shaft, and handle threads occasionally for smooth performance and increased life. Apply a drop of oil on the drive shaft bearings. In freezing or icy conditions, apply silicone spray to ratchet pawl and spacer items. Do not oil or grease brake mechanism items.
  7. Ensure the winch is in good working order. Damaged or severely worn parts can pose unnecessary dangers and may result in personal injury or property damage.
  8. The winch is not intended for the movement of human beings.

WARNING READ INSTRUCTIONS CAREFULLY BEFORE ATTEMPTING TO INSTALL, OPERATE OR SERVICE THIS WINCH. FAILURE TO COMPLY WITH INSTRUCTIONS COULD RESULT IN SERIOUS OR FATAL INJURY. RETAIN THESE INSTRUCTIONS FOR FUTURE REFERENCE.

IMPORTANT SAFETY INFORMATION

  • This brake winch is built for multi-purpose hauling and lifting operations. It is not to be used as a hoist for lifting, supporting or transporting people, or for loads over areas where people could be present.
  • Respect this winch. High forces are created when using a winch, creating potential safety hazards. It should be operated and maintained in accordance with instructions. Never allow children or anyone who is not familiar with the operation of the winch to use it. A winch accident could result in personal injury.
  • Check the winch for proper operation on each use. Do not use if damaged. Seek immediate repairs.
  • Never exceed rated capacity. Excess load may cause premature failure and could result in serious personal injury. This winch is rated on first layer of cable on the hub. Using more layers of cable increases the load on the winch.
  • Never apply load on the winch with the cable fully extended. Keep at least three full turns of cable on the reel. Check the cable on every use. Replace at the first sign of kinks, broken wires, deformation or any other damage.
  • Secure load properly. When the winching operation is complete, do not depend on the winch to support the load.
  • Operate with hand power only. This winch must not be operated with a motor of any kind. If the winch cannot be cranked easily with one hand, it is probably over-loaded.
  • If the winch will be used in freezing, icy conditions, apply silicone spray to ratchet pawl and spacer items, V, W, X, or Y. Do not spray other brake mechanism parts.

ASSEMBLY

Thread the handle onto the winch drive shaft and be certain that a clicking noise is produced when the handle is turned clockwise. Install the spring and locknut (Items E and G) on the end of the drive shaft as shown on parts drawing. These parts may appear to serve no function, but they provide several important fail-safe features, and must not be altered or removed.

WINCH MOUNTING AND CABLE ATTACHMENT

For maximum strength and safe- ty, this winch must be mounted with three 3/8” bolts (M10), washers and lock washers. Use Grade 8 for 1500 lb/680 kg or greater capacity. (See parts draw-ing). Using fewer bolts or alternate locations will result in damage to the winch base and the winch may malfunction.
Attach cable or rope by method shown in sketch.

OPERATING INSTRUCTIONS

Wind cable on winch reel by turning winch handle in a clockwise direction. This should produce a loud, sharp, clicking noise. The load will remain in position when the handle is released. Wind cable off the winch reel by turning winch handle counterclockwise (no noise will be produced). The load will remain in position when the handle is released, but for extra security it is recommended that the handle be turned clockwise until at least two clicks are heard. This will add extra tightness to the brake mechanism. Always satisfy yourself that the winch is holding the load before releasing the winch handle.

IMPORTANT: Sufficient load must be applied to the cable to overcome internal resistance and operate the brake properly, otherwise turning the crank handle counterclockwise will only remove the handle from the shaft – the reel will not turn. The minimum operating load requirement is 50 lb (23 kg) for Models DLB350A, DLB350AG, DLB800A, DLB800AG, DLB1200A and DLB1200AG, 75 lb (34 kg) for DLB1500A and DLB1500AG, 175 lb (80 kg) for DLB2000AG and DLB2500A.
A lockout lever for the purpose of ‘freewheeling’ cable out when there is no load on the winch can be added to all DLB winches except the 350 lb (160 kg) models. To ‘freewheel’ cable out, simply turn the handle coun- terclockwise until lockout lever can be engaged behind handle hub. In this condition cable can be eas- ily pulled from the winch drum.

WARNING: Never put winch in freewheel mode if any potential for a load on the cable exists. Engaging the lockout lever keeps the winch from stopping in the event that a load is accidentally applied.

WINCH MAINTENANCE

In order to insure maximum performance, a periodic inspection for any necessary preventive maintenance must be made. Check at least once annually and more frequently when the winch is exposed to an environment which is particularly dirty or wet. For continued smooth performance and increased life, occasionally grease gears, reel shaft and handle threads. An occasional drop of oil on the drive shaft bearings is also recommended. If winch will be used in freezing, icy conditions, apply silicone spray to ratchet pawl and spacer items V, W, X or Y. Note: Do not oil or grease brake mechanism items H and J.
Keep winch in good working order. Damaged or severely-worn parts create unnecessary dangers and could result in personal injury or property damage.
