ComeUp Utility Winch

This light-duty winch lets you pull ATVs, UTVs, golf carts, and other small vehicles onto your trailer. The integrated design reduces installation time, and the compact size enables the winch to be mounted in most custom cabinets and boxes. The hard plastic external housing protects all the internal components from rain, rocks, and debris. The winch also includes dual brakes to ensure reliable load-holding, a 50' synthetic rope with a fairlead that bolts directly to the winch body, and a circuit breaker that automatically cuts power to the winch if the motor begins to overheat.


Light-Duty, 1.6-Horsepower Motor

ComeUp winch motor

This winch features a 1.6-horsepower, 12-volt DC motor with 4,500 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.


Circuit Breaker

ComeUp Power Unit circuit breaker

There is an inline circuit breaker attached to the positive battery lead. It will interrupt the flow of power from the battery to the winch motor if the motor begins to overheat. When the internal elements of the circuit breaker have cooled it will automatically reset and you can use the winch again.


12-Volt Solenoids

ComeUp Power Unit with solenoid

The winch includes dual 12-volt solenoids that transmit power from the vehicle's battery to the winch motor. One solenoid powers the winch when you are paying out the rope, and the other powers the winch when you are winding the rope in. They are permanently mounted inside the hard plastic winch housing so they're protected from rain, dust, and debris. The copper terminals and stainless steel and carbon steel hardware are also corrosion resistant.


Free-Spooling Clutch

ComeUp Free-Spooling Clutch freespool

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.


The free-spool clutch lever is mounted on the side of the gearbox housing. Flip it up to release the clutch for free-spooling, and flip it back down to reengage the clutch.


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.



Automatic, Load-Holding Mechanical and Dynamic Brakes

This winch includes a mechanical brake and a dynamic brake. This dual braking system provides a physical brake inside the drum and supplemental braking force generated by the winch motor. The 2 brakes operate simultaneously to ensure more reliable load holding when compared with single-brake trailer winches.


The automatic mechanical brake securely holds a load and prevents unintentional payout (or creep). When the winch motor is stopped, a large spring coil inside the drum expands to press against the spring chamber. The pressure of the spring on the wall of the spring chamber creates resistance that prevents the drum from rotating. This spring contracts when the winch is in gear to allow the drum to rotate.


When the winch is pulling the rope in or paying it out, the motor is not applying resistance to the drum. When you stop powering the rope in or out, the dynamic brake uses resistance from the motor to help hold the load.


Hand-Held Remote

ComeUp Hand-Held Remote

The hand-held remote has a 10' lead and an in/out rocker switch so you can operate your winch from the back or side of your trailer. The rocker switch is sealed so it won't get damaged in wet conditions.


There is also a wireless hand-held remote (sold separately) available that lets you operate the winch from up to 90' away.


ComeUp Remote port

There is a rubber-sealed, weatherproof attachment port for the remote control located on the front of the winch. 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. Use the rubber cap to cover the port when it's not in use.


Synthetic Rope

ComeUp Synthetic Rope

The synthetic rope made of Dyneema SK75 fiber that is lightweight yet stronger than steel. This synthetic rope is safer to use than a steel rope because it generates less kinetic energy - and therefore less kickback - if a break occurs. It won't stretch - or creep - over time like steel rope can. And it's also less likely to fray and create sharp strands so it's easier to handle and easier to spool.


The rope winds around a sealed, 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 included to use in conjunction with work gloves (sold separately) so that you can safely handle the rope and hook.


Steel Hook

The hook is made of high-strength forged steel that is heavy duty and rust resistant. It has a spring-loaded safety latch for quick fastening and removal. The hook is permanently attached to a steel thimble on the end of the synthetic rope.


Roller Fairlead

ComeUp 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.


Installation

This versatile winch can be mounted to your trailer in several different ways. The simplest way to install the winch is to bolt it directly to your trailer deck. This does not require a mounting plate or welding, but it does leave a footprint on the deck.


ComeUp installed on trailer front rail

You can install a mounting plate (sold separately) on the front rail of your trailer and bolt the winch to the plate. This elevates the winch so it's easy to reach and frees up valuable space on your deck, but will require welding the mounting plate to the rail. You can also weld the mounting plate to the front bumper of the trailer to position the winch at deck level without infringing on valuable deck space.


The compact design allows the winch to easily fit into most custom cabinets or boxes. This 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

Layers of RopeCapacity (lbs)Total Rope on Drum (ft)
1st Layer4,5007.9
2nd Layer3,72217.4
3rd Layer3,17428.6
4th Layer2,76641.4
5th Layer2,45150

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.


Winch Capacity

There are a number of factors you must consider when determining the appropriate trailer winch for your application. You will need to know your gross vehicle weight, the angle and distance of the slope you will be pulling up, and whether the vehicle or object is static or rolling. The GVW is the stand-alone weight of your vehicle plus the weight of any items in and on the vehicle.


Rolling Load Winch Capacity

Percent InclineRolling Load Capacity (lbs)
Level Surface45,000

10 (6°)22,590
20 (11°)15,300
30 (17°)11,745
50 (26°)8,370
70 (35°)6,885
100 (45°)5,805
drawing

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

Double-Line Pulling

Increase the pulling capacity of your winch by doubling up the rope with a pulley block (CU881079 - sold separately). Secure the pulley block to the vehicle you are pulling with a bow shackle (CU881092 - sold separately) to provide a strong anchor for your double-line pull. Using double-line operation will approximately double your winch's pulling capacity.

Video Transcript for ComeUp Roller Fairlead 4500 lb Utility Winch Review

Today we're going to be taking a look at the ComeUp DV-4500si Utility Winch, part number CU644501. The ComeUp Utility Winch is the perfect solution for getting your wheeled equipment, such as your ATVs, UTVs, or in this case our golf cart, up onto our trailer. It features a free spool clutch lever, which will allow us to pull out rope out manually to help us save time, help prevent wear and tear on our motor, and help save battery power. The rope itself is constructed of a tough, lightweight synthetic. It's going to be stronger, safer, and easier to handle than steel. The synthetic rope has about a 38 inch protective abrasion sleeve to further protect the rope.

It has ainaudible 00:00:41 which is going to help reduce the wear and the strain on your rope. The heavy gauge steel hook features a latch to help prevent it from disconnecting. It also has a hand-saver strap, which when used in the conjunction with gloves, can really protect your hands and make it easier to pull out the rope. It has a dust cap, which can help keep out debris and any other elements. It has a hand-held switch remote, which plugs into your winch and can be operated at a distance. The remote features a cable in and out toggle switch and has finger holes for a nice, good grip.

It has a 10 foot long cable to keep us at a safe distance and keep a close eye on things. The 4500si features a 1.6 horsepower high torque permanent magnet motor that delivers a rated line pull of 4500 pounds. It's dimensions are about 16 and 1/2 inches long, 9 and 1/2 inches wide, and 6 and 1/2 inches tall. It comes with all the inaudible 00:01:45 hardware you need and all the wiring you need to get it hooked up to your power source, including a solenoid pack to prevent overheating. Now that we've gone over some features, I'll go ahead and show you how to hook up. We've got it in free spool mode so let's go.

Now we're using a shackle in conjunction with our cart here today because the hook won't quite fit in the anchor point. Now if you need a shackle, we've got a wide variety of different size here at etrailer.com. You can pick one up. The one we're using today is part number GS07. We're just going to go ahead and hook it in, make sure our latch is closed.

Let's go ahead and winch it up. Now it's always important to be safe. You want to make sure that your trailer's hooked up and secured to your vehicle, which it is. Let's go ahead and grab our remote, get to a safe distance, and start winching. We'll flip down the free spool clutch lever. Now we're all set. It can also help us unload our wheeled equipment. The ComeUp Utility Winch features dual dynamic and mechanical brakes for strength and reliability to ensure there is no slippage when loading and unloading our cargo. Now if you'd like to double the pulling capacity of your winch, you can pick up the ComeUp Snatch Block. That's going to be part number CU881082. The looped end simply connects to whatever you're winching, the rope comes around the cable, and connects back to the trailer. That's going to complete our look at the ComeUp DV-4500si Utility Winch, part number CU644501.

It came on time and was packaged great. I am using the winch to load my race cars into my enclosed trailer. It is working very well. It is slow enough to make loading safe but fast enough to not take all day. I am very pleased.


Comments
It is a little over a year now of using my winch to load my cars. It is still working great. I have had only one issue that I think I caused, since it has never happened again.

This has been a great winch. We use it hard almost every day loading portable buildings. My only issues 1) I was led to believe it came with a remote control, it didn't 2) the hard wired control is giving us problems starting and stopping the winch.

Ask the Experts about this ComeUp Electric Winch

  • Electric Winch and Surge Actuator Recommendation for Trailer Towing 9,500 lb Boat
    When it comes to choosing a winch for a boat trailer, there are a few general rules we can use. The boat-size-to-winch capacity is generally 2 to 1. With good rollers and short winching distances, the ratio can increase to 3 to 1 and with wooden bunks and long winching distances, you will want to reduce the capacity to 1 to 1. For an electric winch that would work well for you the ComeUp winch part # CU644501 would work well. This has a 4,500 lb capacity and a 50 foot long synthetic...

  • Could ComeUp Winch Fit on Tahoe Boat Trailer
    The ComeUp winch # CU644501 can attach to the winch mounting bolt pattern you have but it's going to require you to drill a new hole as it uses a 2-bolt attachment that inline from front to back. So you'd need to drill a new hole between the two slotted holes you have.

  • Winch Recommendation for 7800 lb Boat
    For a boat that weighs 7,800 lbs you'd need a winch with a capacity of at least 3,900 lbs. Which there aren't standard hand winches with that capacity so you'd need to look into an electric winch like the ComeUp part # CU644501 which has a capacity of 4,500 lbs. This comes with a strap.

  • Fastest Electric Winch With 500 Pound Capacity
    Winches with faster speeds and additional features usually come on higher capacity (more expensive) winches. A good first choice would be the Bulldog # BDW15017 trailer winch suitable for a vehicle or trailer service, with a 3400 pound capacity. Line speed is 5 to 15 foot per minute depending on load. Also includes hand-held wired remote control. A faster winch is the Come Up # CU644501 winch, also suitable for trailers, and with a 4500 pound capacity. Line speed is 1.3 to 21.3 feet...
