This compact, standard-duty trailer winch lets you pull cars, trucks, mini-vans, and other vehicles onto your trailer. You can mount the winch directly to your trailer deck or front rail with the included mounting plate. The side-mounted power unit and rotating gearbox allow the winch to fit easily into most custom cabinets or boxes. And it includes a hand-held remote, wire rope, roller fairlead, and a free-spooling clutch.

Heavy-Duty, 5.2-Horsepower Motor

This winch features a 5.2-horsepower, 12-volt DC motor with 7,800 lbs of line pull. The permanent magnet motor offers the same line-pulling power and speed as a series-wound motor of comparable size, but it's lighter and uses less current. The motor is constructed of durable, corrosion-resistant materials including the powder coated housing, copper battery terminals, and zinc-plated steel hardware.

Power Unit with Sealed Contactor

The contactor - or solenoid - transmits power from the vehicle's battery to the winch motor. The 450-amp contactor - located inside the power unit - is sealed to meet IP67 specifications for water and weather resistance. The copper terminals and zinc-plated hardware are corrosion resistant.

There is a rubber-sealed, weatherproof attachment port on the power unit for the remote control. An integrated rubber cap lets you cover the port when it's not in use.

Free-Spooling Clutch

The free-spool clutch enables you to pull out the rope by hand. This saves battery power, prevents the brake from wearing down prematurely, reduces wear on the motor, and is much faster than waiting for the drum to unroll the rope. To release the clutch for free-spooling simply rotate the handle to the position indicated by the stick figure icon on the label. To reengage the clutch, rotate the handle back to the position indicated by the vehicle icon on the label.

The clutch is driven by a 3-stage planetary gear train. This provides more speed than traditional worm gear drives or 1- or 2-stage planetary gear trains. An internal spring-loaded pin locks it into or out of gear when the handle is turned.

The gearbox can be rotated in 30-degree increments to 12 different positions to ensure that you can easily access the clutch handle no matter where the winch is mounted. This is great for installation in a custom cabinet or box where space is limited.

The chrome-plated clutch handle is stylish and weather resistant. The steel gearbox is sealed to keep out moisture, and it has a rust-resistant black powder coat finish.

Automatic, Load-Holding Mechanical Brake

The automatic mechanical brake securely holds a load and prevents unintentional payout (or creep). A large spring coil contracts when the winch is in gear and the drum is winding in. When the winch stops, the load starts to pull and the spring expands to press against the spring chamber. The pressure of the spring on the wall of the spring chamber creates resistance to stop the drum from rotating outward. At maximum pressure the brake holds 100 percent of the load.

The friction created when the spring is pressing against the spring chamber creates heat. That heat is quickly dispersed away from the motor shaft and through the gearbox. This prevents potentially damaging heat buildup near the motor.

Weather-Resistant Hand-Held Remote

The hand-held remote has a 20' lead and in/out rocker switch so you can control your winch from the back of your trailer. The rocker switch is sealed and water resistant so it won't get damaged in wet conditions. Simply plug the durable plastic remote into the power unit when you need to use it, and disconnect it to store it away when you aren't using it.

The wireless remote kit (BDW20156 - sold separately) lets you operate the winch from up to 100' away.

Wire Rope

The wire rope is made of high-strength, aircraft-grade galvanized steel that is zinc-plated to resist abrasions and withstand harsh UV rays, chemicals, and extreme temperatures. It includes a spring-loaded tensioner that ensures the rope correctly spools onto the drum. A rock bag (BDW20048 - sold separately) is recommended for added protection. The rock bag helps prevent a broken rope from snapping back if it breaks by forcing it to the ground.

The rope winds around a solid steel drum. The mounting flanges are strong enough to resist bending or breaking if the rope wrap becomes uneven and excess stress is put on the drum.

A hand-saver strap is also included to use in conjunction with work gloves (BDW20070 - sold separately) so that you can safely handle the rope and hook.

The removable clevis hook is constructed of high-strength forged alloy steel that is heavy duty and rust resistant. It has a spring-loaded safety latch for quick fastening and removal. The hook attaches to the steel thimble on the end of the wire rope.

Roller Fairlead

The roller fairlead has a thick steel frame with 4 steel rollers. The rollers reduce friction when you're pulling the rope in or paying it out, and they prevent the rope from becoming pinched when pulling at extreme angles. The rollers have a silver-zinc-plated finish that is tough and corrosion resistant. The fairlead installs with zinc-plated hardware.

Rugged Construction

The winch is constructed of strong, durable materials that are able to withstand any weather condition or terrain. The motor housing and gearbox are made of corrosion-resistant powder coated steel. The contactor is sealed to keep water out, and the power unit is made of heavy-duty yet lightweight plastic. The steel tie bars and side frame drum supports help to create a strong and rigid winch body.

Installation

This versatile winch can be mounted to your trailer in several different ways. You can bolt the included plate onto the deck of your trailer and attach the winch and fairlead. Counter-sunk bolt holes in the mounting plate ensure that the hex heads of the included bolts don't protrude above the trailer's flat surface. This is the easiest method and does not require welding, but it does leave a footprint on your deck.

You can mount the plate to the front rail of your trailer. This method elevates the winch so it's easy to reach and frees up valuable space on your deck, but will require welding the plate to the rail. You can also weld the plate to the front frame of the trailer so that the winch sits at at deck level without using up space on the deck.

The compact, low-profile design allows the winch to easily fit into most custom cabinets or boxes. This method keeps the winch out of the elements and keeps it hidden. Many cabinets and boxes can even be locked to protect the winch from would-be thieves. You can also install a dedicated battery inside or near the cabinet to power the winch. This prevents the winch from putting a strain on your vehicle's battery, and it eliminates the need to run a power lead all the way to the front of your truck.

Winch Line Pull Capacity

The line pull capacity of your winch is determined by the maximum load your winch can pull with a single layer of rope on the drum. As more layers of rope are wound onto the drum, pulling the same load requires more force, leading to a loss in winching power. With a 2nd layer of rope around the drum, your line pull capacity is reduced by approximately 14 percent. With 3 layers on the drum, the line pull capacity is reduced by approximately 23 percent, and with 4 layers on the drum it is reduced by approximately 35 percent.

Note: It is recommended that you begin any line pull with a minimum of 5 wraps and a maximum of 2 layers of rope on the drum.

Vehicle Recovery and Winch Capacity

To select the appropriate trailer winch for your application, determine your gross vehicle weight. The GVW is the stand-alone weight of your vehicle plus the weight of any items in and on the vehicle. Once you have determined the GVW of your vehicle, choose a winch with a capacity that is 1-1/2 times your GVW. Using that formula, this winch - with an 7,800-pound capacity - will work for vehicles with an approximate GVW of 5,200 pounds.

Rolling Load Winch Capacity

To calculate your winch's rolling load capacity - the amount of weight it can pull up an incline - you must multiply the line pull capacity by a factor determined by the degree of the incline.

The multiplication factors shown in the chart, right, include a 10-percent rolling friction factor.

Note: A 5-percent - or 3-degree - incline is a 1/2' rise over a 10' distance. Follow the chart to determine your winch's rolling load capacity.

Double-Line Pulling

Increase the pulling capacity of your winch by doubling up the rope with a pulley block (BDW20028 - sold separately). Secure the pulley block to the vehicle you are pulling with a bow shackle (BDW20020 - sold separately) to provide a strong anchor for your double-line pull. Using double-line operation will approximately double your winch's pulling capacity.
