There are 3 standard units in the UniJack™ range - the UJA1, UJA2 & UJA3.

The UJA1 is fitted with a 2" (50.80 mm) twin wheel castor and is suitable for most applications. Ground clearance is 24 mm as standard and this can be reduced for lightweight items. WLL 160 kg.

The UJA2 is fitted with an 3” (76.20 mm) single wheel castor. Using the same mechanism as the UJA1 but in a larger body, the UJA2 has a standard ground clearance of 24 mm and a WLL of 200 kg.

This will provide 24mm of ground clearance to the item being moved. The bottom edge of the back plate should also be installed 100mm above the floor when the stage truck is in its resting position.The SWL of the UJA2 is 200 Kg.
