Gojak GJ 5000 Self-jacking skates standard load limit 565kg or 2260kg with 4 units. Faster and safer than floor jacks, Gojaks allow you to move vehicles easily within a tight space. Each Gojak has twin rollers which slide around the tyre and lift the wheel off the ground with just a few clicks of the pedal. The non-marking 360 degree casters let you re-position the car without damaging the floor of the car. Two Gojaks allow you to pivot any car on either axle. Four Gojaks give you trolley-style maneuverability, allowing you to move even the most damaged or disabled vehicles. Weight per skate 13.7kg
