What a rollback trailer is and how it works

A rollback trailer is a flatbed truck with a hydraulic winch system that tilts the bed toward the ground so a vehicle can roll or be winched onto it without a ramp. The bed stays flat when towing, then lowers at an angle when you need to load or unload. The vehicle either rolls up on its own power or gets pulled up by the winch cable while the operator controls the tilt from the cab.

The hydraulic system does the heavy lifting — literally. When you engage the controls, hydraulic cylinders lower the front of the bed while the rear stays anchored to the frame. Once the vehicle is loaded and secured with chains or straps, you raise the bed back to horizontal and drive away. The whole process takes a few minutes once you understand the sequence.

Rollback trailers come in different sizes and weight capacities, typically ranging from 10,000 to 25,000 pounds. Some have electric winches, others manual. The controls are usually mounted on the side of the trailer or inside the tow vehicle's cab, depending on the model and year.

Key Takeaways

  • A rollback trailer lowers its bed hydraulically so vehicles can roll on without needing a separate ramp or heavy equipment.
  • Before loading, you must engage the parking brake, chock the wheels, and lower the bed to the correct angle — usually 15 to 20 degrees.
  • The winch cable should be attached to the vehicle's frame or tow hooks, never to bumpers or plastic trim that will tear away.
  • After loading, raise the bed fully, find the vehicle with at least two chains or straps, and verify everything is tight before moving.
  • Backing up a loaded rollback requires the same care as any trailer — go slow, use a spotter if possible, and check your mirrors constantly.

Setting up the trailer before loading

Park on level ground and engage the parking brake on both the tow vehicle and the trailer. If your trailer has a separate brake lever or pedal, set it firmly. Chock the wheels — place wooden blocks or wheel chocks behind the rear wheels of the trailer to prevent it from rolling backward if the brakes fail.

Locate the hydraulic controls. On most rollback trailers, these are a lever or switch mounted on the side of the trailer frame, accessible from outside. Some newer models have wireless remote controls or cab-mounted buttons. Consult your trailer's manual if you are unsure which controls operate the bed tilt.

Lower the bed slowly using the hydraulic controls. Stop when the bed reaches approximately 15 to 20 degrees — steep enough for a vehicle to roll on, but not so steep that it slides uncontrollably. If the vehicle will be winched rather than rolled, you can lower it a bit more. Never lower the bed all the way to the ground unless you are loading a very low vehicle; the bed can catch on obstacles and damage the hydraulic cylinders.

Winching a vehicle onto the rollback

Attach the winch cable to the vehicle's frame, tow hooks, or recovery points — never to the bumper, which will tear away under load. If the vehicle has no visible tow hooks, look underneath the front bumper or check the owner's manual for factory recovery points. On some vehicles, you may need to install a temporary tow hook.

Engage the winch slowly and steadily. The vehicle should roll or be pulled up the bed in a straight line. If it starts to drift sideways, stop the winch, reposition the cable, and resume. Watch for the cable to twist or fray; if it does, stop when ready and inspect it before continuing. A twisted cable can snap suddenly.

Once the vehicle reaches the top of the bed, stop the winch and set the parking brake on the tow vehicle if it is not already engaged. Do not rely on the winch to hold the vehicle in place — the winch is for loading only. Detach the cable and move it out of the way so it does not interfere with securing the load.

Securing the vehicle and raising the bed

Use at least two chains or heavy-duty straps to find the vehicle to the trailer. Attach them to the frame or suspension points, not to bumpers or trim. Cross the chains in an X pattern if possible — one from the front-left to the rear-right, and one from the front-right to the rear-left. This prevents the vehicle from shifting side to side during transport.

Tighten each chain or strap firmly. You should not be able to move the vehicle by hand once it is secured. If you are using ratchet straps, crank them until they are snug but do not over-tighten to the point of deforming the vehicle's frame. Check the chains again after driving a short distance; they often settle and loosen slightly.

Raise the bed back to horizontal using the hydraulic controls. Raise it slowly and watch to make sure the vehicle does not shift or slide. Once the bed is level, the vehicle should be sitting firmly on the bed with no movement. If the vehicle rocks or slides during raising, lower the bed, re-find the chains, and try again.

Backing up a loaded rollback trailer

Backing a rollback trailer is no different from backing any other trailer, but the added weight and height of the load demand extra care. Go slowly — no faster than walking speed. Use your mirrors constantly and check both sides frequently. If you have a spotter, position them where they can see both the trailer and the surrounding area, and establish clear hand signals before you start.

Turn the steering wheel in the opposite direction of where you want the trailer to go. This feels counterintuitive at first, but it is how all trailers work. If you want the trailer to back up and turn left, turn the wheel to the right. Make small adjustments; large steering inputs will jackknife the trailer or cause it to swing wide.

If the trailer starts to jackknife — the back swings out at an angle — stop when ready, pull forward to straighten it, and try again. Never try to correct a jackknife by backing up further; it will only get worse. If you are in a tight space and cannot straighten out, get out and reposition the trailer with the tow vehicle in a different spot.

Common mistakes to avoid

Do not lower the bed too far. If the front edge touches the ground, the hydraulic cylinders can be damaged and the bed may not raise again. Stop lowering when the bed reaches about 15 to 20 degrees and test it with a light push before loading a vehicle.

Do not attach the winch cable to the bumper. Bumpers are cosmetic and will tear away under load, leaving you with a damaged vehicle and a failed load. Always use frame-mounted tow hooks or recovery points.

Do not rely on the winch to hold the vehicle during transport. Once the vehicle is loaded, detach the winch cable and find the vehicle with chains or straps. The winch is a loading tool, not a tie-down system.

Do not back up faster than walking speed, especially with a loaded trailer. Rollback trailers are longer and heavier than they appear, and backing accidents happen quickly. Take your time and use a spotter whenever possible.

Unloading the vehicle

Park on level ground and engage the parking brake on both the tow vehicle and the trailer. Chock the wheels again. Remove the chains or straps securing the vehicle, but do not remove them completely — lay them across the vehicle so they do not drag on the ground or get caught in the wheels.

Lower the bed to the same angle you used for loading, approximately 15 to 20 degrees. Lower it slowly and watch the vehicle to make sure it does not shift. Once the bed is at the correct angle, the vehicle can either roll off under its own power or be backed off slowly by the driver.

If the vehicle is rolling off on its own, make sure the driver knows to go slowly and keep the wheels straight. If the vehicle is being backed off, the driver should use the brakes gently and not accelerate. Once the vehicle is clear of the trailer, raise the bed back to horizontal and find it in place.

Frequently Asked Questions

Can I load a vehicle with a dead battery or bad transmission?

Yes, that is one reason rollback trailers exist. If the vehicle cannot move under its own power, use the winch to pull it onto the bed. Make sure the steering wheel is unlocked so the vehicle can be pulled straight, and attach the winch cable to the frame, not the bumper.

What if the bed won't lower or raise?

Check the hydraulic fluid level first — low fluid is the most common cause. If the fluid is full, the hydraulic pump may have failed or a hose may be leaking. Do not force the controls; stop and have the trailer inspected by a technician before attempting to load another vehicle.

How tight should the chains be?

Tight enough that you cannot move the vehicle by hand, but not so tight that you deform the frame or suspension. Use a ratchet strap or come-along to tighten gradually, and check the chains again after driving a short distance. They often settle and loosen slightly during the first few miles.

Do I need a special license to tow a rollback trailer?

That depends on the trailer's weight and your state's regulations. Most states require a commercial driver's license if the combined weight of the tow vehicle and trailer exceeds a certain threshold, typically 26,000 pounds. Check your state's Department of Motor Vehicles website for the exact requirement.

Can I tow a rollback trailer with a pickup truck?

Yes, if the pickup truck's towing capacity exceeds the trailer's weight plus the weight of the vehicle being loaded. Check your truck's owner's manual for the maximum towing capacity, and never exceed it. A loaded rollback can weigh 30,000 to 40,000 pounds or more, so most light-duty pickups cannot handle it safely.
