When you need the extra muscle to move your trailer, caravan, camper, horse float, boat or anything else that uses a jockey wheel then you need the Maxi-Pro 12V Electric Motorised Jockey Wheel. The jockey wheel is capable of moving up to 2722kg's (6000lbs) on an inline of up to 7 degrees. With both forward and reverse, a wide (8cm) heavy duty rubber wheel and an automatic braking system moving your trailer around becomes a breeze. With a special jockey wheel locking system this means that once locked no-one can remove the jockey wheel without a key. The unit is supplied with 4 keys, so you'll always have one to hand! The unit needs to be powered by a 12V DC battery with a minimum size of 24Ah (not included). Jockey wheel can be used in manual mode (freewheel option) by roating yellow cap located on the side of the wheel. Please note: This unit will not suit double axle trailers. Bulky items will attract extra cost. You can then decide to pay for the postage or cancel the order.
