Product catalog summary
Introduction
This manual provides essential guidelines for the installation and operation of planetary winches by dp Manufacturing, Inc. It stresses the importance of thoroughly reading the manual to prevent serious injury or death.
General Warnings
  • Avoid disengaging the gearbox under load to maintain control.
  • Keep the last five wraps of wire rope on the drum for load holding.
  • Winches are not for lifting or moving people.
  • Maintain a safe distance from the winch and wire rope under load.
  • Ensure proper alignment and support to prevent efficiency loss or failure.
Safe Operating Practices
  • Familiarize with controls and proper use before operation.
  • Keep the area clear of people.
  • Wear safety gear like glasses, goggles, and gloves.
  • Avoid operating under the influence of alcohol or drugs.
  • Use only manufacturer-approved accessories.
  • Inspect and repair the winch if it behaves abnormally.
  • Follow international safety standards during installation.
Warning Label Locations
Warning labels are placed on various parts of the winch. Their removal or defacement is the purchaser's responsibility.
Hydraulic System
  • Include an open center or motor spool valve for correct operation.
  • Do not exceed the winch's pressure rating to prevent failure.
Winch Mounting
  • Mount close to the center and perpendicular to the line pull direction.
  • The mounting surface must be flat and rigid.
  • Maintain proper fleet angle to prevent wire rope failure.
Winch Installation
  • Follow specific steps for wire rope installation.
  • Do not allow wire rope to extend past the drum edge.
  • Ensure at least five full wraps of wire rope remain on the drum.
Winching Principles
Understanding hydraulics and equipment application is crucial. Factors include total weight, surface drag, and gradient resistance. Calculations for rolling resistance are provided.
Gradient Resistance
Calculated as 1/60th of the vehicle's weight per degree of slope. A table provides gradient values for various height-to-distance ratios.
Use of Snatch Blocks
Snatch blocks increase pulling power or change pull direction. Diagrams illustrate configurations like self-recovery and indirect pulls. Maintain a minimum distance between snatch blocks and ensure the winch's capacity is not exceeded.
Accessories
Cable hold-down devices and fairleads are discussed. Proper maintenance and usage are emphasized to prevent damage or failure. Maintain the correct fleet angle and limit wire rope contact with fairlead rollers.
Troubleshooting
Common issues like hydraulic oil leaks, winch not pulling load, and brake problems are addressed with potential causes and corrective actions. Specific pressure checks and component replacements are recommended.
General Information
Lubrication points for fairlead rollers and pneumatic systems are outlined. Extended storage procedures include cleaning, lubricating, and protecting components from corrosion.
Hydraulic System
Fluid specifications emphasize maintaining correct viscosity and cleanliness. Recommendations for fluid types and maintenance schedules are provided.
Winch Lubrication
Gear lubrication specifications include viscosity requirements and performance standards for lubricants.
Lubrication Specifications and Procedures
  • Lubricant Types: Shipped with GL5 80W90 lubricant. Recommended lubricants vary by temperature.
  • Change Interval: Initial change after 10 hours; subsequent changes every 250 hours or annually.
  • Lubrication Level: Check oil level with winch centerline horizontal.
  • Grease: Use grease conforming to MIL-G-10924 for fairlead rollers.
Oil Check and Fill Procedure
  1. Remove oil fill plug and check oil level.
  2. If overfull and thin, check for hydraulic oil leakage.
  3. Add specified gear lubrication oil as needed.
  4. Inspect for leaks if oil level is consistently low.
Oil Drain and Replacement Procedure
  1. Remove oil drain & fill plug and drain oil.
  2. Clean drain plug, replace, and refill with oil to proper level.
  3. Change oil after the first 10 hours, then annually.
Warranty Information
  • Coverage: Covers defects in material and workmanship for one year from shipment.
  • Remedies: Repair, replace, or refund for defective items.
  • Exclusions: Does not cover improper use.
  • Limitations: No liability for indirect or consequential damages. Non-transferable.

Do not disengage gear box while winch is under load.Immediate loss of load control will result. The last five wraps of wire rope must be left on the drum to assist the wire rope clamp in holding the load. Winches are not to be used for the lifting or moving of persons. Wire rope can break without warning. Always keep a safe distance from the winch and wire rope while under a load. Consult the wire rope manufacturer for wire rope ratings and maintenance procedures. Failure to adequately align, support, or attach winch to a suitable mounting base could result in a loss of efficiency or premature...

Knowledgeable parties should install all > dp winches. Consult > dp Manufacturing if questions should arise. When users or third parties modify the winch or the vehicle that a winch is mounted to, they become responsible for the modifications and any results caused by the modifications. The finished installation should be able to withstand the maximum load applied to the vehicle by the full rated load of the winch. Vehicles that > dp winches are mounted on must have sufficient structural capacity to support the combined load that can be produced by all of the winches on the vehicle. 1. The winch...
