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)

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 Electric Winch - Car Trailer Winch - CU644501 Review

Today we're going to be taking a look at part number CU644501. This is the ComeUp DV-4500si Utility Winch. It's going to have the synthetic rope design. You see that in there, a nice heavy duty rope. Now this winch is designed to be a flexible tool for loading trailers or moving various vehicles or boats into the proper position. Pretty nice compact design. It's also going to be lightweight compared to winches of the same size and capacity.

It's going to be very versatile for a wide range of applications on trailers and boats. We're going to have a weather-resistant, plastic housing for strength and durability. The plastic housing is just on this half of the winch. Over here, we got a nice metal construction, durable coated finish on it to protect it from rust and corrosion, and then we do have a plastic cap right here over the synthetic rope to keep it protected as well. Now this winch does have the power-out function and the power-in function. Power-out function is going to allow for rapid rope payout.

Power-in function is going to allow you to easily pull the load in. It's going to come with the remote. That way you can control the in and out functions of the winch from a safe distance. It's going to have about 10 feet of cord. Its got the plug right here, that plugs directly into this plug right here on the winch.

Very easy access to get that connected. Nice, large remote. Its got multiple finger indentions on it for a nice controlled grip. Then it's got the toggle switch there that allows you to control the out and in functions of the winch. Now this is going to be a high torque, permanent magnet motor. It's going to deliver high line pull at a lower amp draw. This unit is going to use a dual brake system, so it's going to insure holding the load without slippage. It's going to have the automatic load holding mechanical brake in the motor dynamic brake for strength and reliability.

Right here on the sticker it's going to give the capacities. This is going to give us a rolling load capacity of 37,500 pounds. It's rated at 4,500 pounds with a single line pull. Now at max load this winch is going to have a line speed of 1.3 feet per minute with a power draw of 330 amps at 12 volts. With no load it's going to have a line speed of 21.3 feet per minute with a power draw of 25 amps at 12 volts. The motor is a 1200 watt, 1.6 horsepower, 12 volt permanent magnet motor. It's going to feature a clutch right here on the side. It's going to be this flip up lever. With it down that means that it's engaged. You can use the remote control for functioning the winch. Then with it up it's disengaged. Now this allows the winch to go into free spool mode so you can simply just pull on the hook, extend the line out allows for fast synthetic rope payout. That is going to allow us to easily run the rope to our load and connect it, whether it's to a load or anchor point or whatever. Up is disengaged. Down is engaged. Here on the back side we're going to have our battery leads. Red and black wiring. They are going to have ring terminals on it. You're also going to have your circuit breaker. This is going to shut the winch off to help prevent overheating of the motor if it gets strained too much, or if the amps increase to a certain amount it's going to shut the motor off to keep it from overheating. We do have the battery leads. They're going to be connected to the contactor here at the back. Contactor is sealed, it's built into the housing. It is integrated for complete protection of the wiring and of the system. Now when it comes to the gear ratio, it's going to be 170:1. It's going to use a 3-Stage planetary gear box. It's going to deliver reliable and durable performance. inaudible 00:03:59 leads is going to be already attached to the winch body. That is going to keep our rope intact. It's going to reduce friction, which is going to reduce inaudible 00:04:11 over time or repeated use. That is built in right here at the front. The drum size is going to have a diameter of 2.1 inches with a width of 3.3 inches. It's going to use SK-75 synthetic rope. That's going to measure 50 feet long by a 1/4 of an inch in diameter, and it's going to come with a grade 70 forged steel construction hook with a pin and clip to keep it attached. Its got the safety latch strap right there to prevent accidental disconnecting, and its got the hand saver strap as well. Now it's going to come with your mounting hardware. This bolt right here is going to be to mount your circuit breaker. Then the rest of the hardware is going to be designed to mount the winch to a mounting surface. It's going to use two mount holes here on the bottom. We got hole number one and hole number two. These are going to be separated apart from one another on center by 3 and 11/16 of an inch. Now the winch itself is going to weigh around 28 pounds. It's going to give us an overall length measurement, edge to edge, of about 16 1/2 inches. Overall width measurement: That is going to measure about 9 inches from front to back. The overall height: That is going to give us a measurement of about 6 inches tall. That is going to do it for today's look at 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. 418430


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.

Review from a similar ComeUp DV Series in Electric Winch


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. 466122

Review from a similar ComeUp DV Series in Electric Winch


Package arrived in a box which was certainly not designed to protect the product; it arrived in tatters. I have yet to put the product together but it looks good. Price was fair and delivery time was very good. Pat and Molly were very helpful! 590581
