Electric Winch Guide
Using the Electric Winch on the Car Hauler
The 20′ car & equipment hauler in our fleet comes equipped with a Domin8r 12,000-lb electric winch mounted at the front. It’s there for one job: loading vehicles or equipment that can’t move under their own power onto the trailer. Used correctly, it’s safe and easy. Used carelessly, a winch line under load is one of the most dangerous tools you’ll touch.
Before you start
- Park the trailer on the flattest ground you can find.
- Chock the trailer wheels. Front and back. Don’t skip this.
- Confirm the trailer is hitched to your truck and the truck is in park with the parking brake set.
- The truck engine should be running — winching draws significant current and a running engine keeps the battery topped up.
- Wear gloves. Steel cable develops “burrs” that will rip your hands. Synthetic line is gentler but still abrasive.
- Clear bystanders. Nobody stands within a 10-foot radius of the winch line, and absolutely nobody stands in line with the winch cable (front or back).
01
Connecting to the vehicle
- Switch the winch to freespool (clutch lever on the winch body — disengages the drum so you can pull cable out by hand).
- Pull the cable out to the vehicle. Keep tension on it as you walk so it doesn’t bird-nest on the drum.
- Connect to a rated tow point on the vehicle — a frame loop, a tow hook, or a recessed tow ring. Never connect to a bumper, a suspension component, a tie-down loop rated for transport only, or a trailer hitch ball (the most common fatal-injury misuse).
- Use a D-shackle or tow strap with a loop to connect — don’t hook the winch hook directly to a small hole if the hook can pop out under load.
- Re-engage the clutch so the drum is locked.
02
Winching in
- Plug the wired or wireless controller into the winch port (the Domin8r supports both).
- Press IN in short bursts to take up slack and align the cable with the drum.
- Stay out of the cable’s plane. Imagine a line drawn from the winch to the vehicle, extended in both directions — don’t stand on that line. If the cable snaps, it whips along that line with enough force to kill.
- Drape a heavy blanket, jacket, or commercial winch line damper over the middle of the cable. This dampens whip if the cable fails.
- Press IN steadily. The vehicle should track up the ramps and onto the trailer deck. If it veers, stop and reposition.
- If the winch slows or stops under load — release the button, let the motor cool, and try again. Don’t hold the button against a stalled winch; you’ll burn the motor.
- Continue winching until the vehicle is fully on the trailer and positioned correctly per the 60/40 rule.
03
Securing after winching
The winch line is NOT a substitute for tie-downs. Once the vehicle is in position:
- Set the vehicle’s parking brake (and put it in gear if it’s a manual).
- Strap the vehicle down with four-point tie-downs to the trailer’s D-rings.
- Then release tension on the winch line and disconnect.
The winch holds the vehicle while you load. Tie-downs hold it for the drive.
04
Spooling the cable back
With the vehicle now strapped down, switch the winch back to freespool, pull the slack cable back to the winch, then re-engage the clutch and use the IN button to wind the rest in tightly. A cable spooled loosely will bird-nest the first time it gets a load on it.
