VEVOR JY01 Electric Trailer Dolly: 5000 lb capacity, specs and fit

The VEVOR JY01 is an electric trailer dolly, sometimes called a trailer mover or jockey wheel. It clamps onto a trailer's tongue and drives the trailer short distances, so one person can position a caravan, boat or utility trailer in a driveway, yard or storage space without hitching a vehicle.

What the figures mean

VEVOR says the dolly can move trailers up to 5000 lbs. It lists a 600 lb load capacity, which refers to the weight the unit can carry on the tongue, and a 350W 12V motor. Maximum moving speed is 22 ft/min, which is a slow walking pace by design, because precision matters more than speed when you are lining up a trailer.

Clamp and fitting

The bracket clamp adjusts from 12 to 24.8 inches, so you raise or lower it to match your trailer's tongue. VEVOR says the bracket plate has been thickened from 0.2 to 0.24 inches, with extra welded blocks for reinforcement. The dolly measures about 16.5 x 4.5 x 31.5 inches and weighs 29.7 lb (about 13.5 kg), so it is light enough to lift on and off.

Wheel and control

An 8-inch solid rubber wheel rotates freely for steering. A handle gives control of direction, and the listing says the dolly includes an automatic braking function. Solid rubber won't go flat, though it gives a firmer ride than an air tyre.

Where and how to use it

VEVOR gives clear limits. Use it on hard surfaces such as asphalt or concrete, and do not use it on gravel, sand or loose dirt. It is not recommended for ramps steeper than 5 degrees or for dirt and gravel roads, and it should not be used in the rain. The listing says it has passed CE certification. Follow the manual on operation, braking and safe handling, particularly on any slope.

Who it suits

It suits owners of caravans, boats and similar trailers who keep them at home and need to reposition them on flat, paved ground, especially where reversing a vehicle is awkward or the space is tight.

What to check before you buy

• Trailer weight: compare the loaded weight of your trailer with the 5000 lb figure, and the tongue weight with the 600 lb figure.
• Tongue fit: make sure the 12 to 24.8 inch clamp range suits your tongue height and shape.
• Surface: check that your parking spot is hard, flat and dry.
• Slopes: measure any ramp or incline against the 5 degree guidance.
• Power: confirm what 12V battery the unit needs and whether one is included.
• Storage: think about where to keep it dry, since it should not get wet.
