UniJack - The Best Lifting Unit for Heavy Stage Scenery

Overview

The UniJack™ system was the major building block in the Triple E product range when the company first started. Now several thousand UniJacks™ later it is still doing the work it was designed for on stages throughout the world. The system comprises the basic lifting unit with a range of accessories that allow easy handling of heavy scenery. Originally designed for scenic trucks on theatre stages, the UniJack™ can also be used for all types of industrial equipment such as machinery, workbenches, display cabinets and counters. All can be moved or braked with ease.

Specification

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

The standard UJA1 is fitted with a 2" (50mm) twin wheel castor and is suitable for most applications. It is recommended that this is installed with a 10mm clearance between the floor and castor so that the foot pedal is at the most efficient part of its travel as it starts to lift. This gives 24mm of ground clearance to the piece you are moving. If lightweight pieces are to be moved, then clearance may be reduced to give more lift. This unit may be fitted with the UJA5 stud set and locking catch to create a lift off UJA1/5. SWL 160kg.

The standard UJA2 is fitted with a 3" (80mm) single wheel castor. The internal mechanism is the same as the UJA1 but has a larger body in order to accommodate the larger castor and may therefore be used with heavier loads. It is recommended that this is installed with a 10mm clearance between the floor and castor so that the foot pedal is at the most efficient part of its travel as it starts to lift. This gives 24mm of ground clearance to the piece you are moving. This unit may be fitted with the UJA5 stud set and locking catch to create a lift off unit UJA2/5, SWL 200kg.

The standard UJA3 has the same body as the UJA1 but is fitted with a rubber brake foot designed to hold a stage truck in position by lifting a fixed castor from the floor. The unit should be fitted so that it only lifts the fixed castor with a minimum clearance. The brake foot and plate may be purchased separately (UJA8) to convert a UJA1 to a UJA3. The rubber foot can also be purchased separately (UJA8R) to replace any that are worn out. This unit may be fitted with the UJA5 stud set and locking catch to create a lift off unit UJA3/5, SWL 275kg.

All the UniJack™ units require the UJA6 keyplate when used in conjunction with the UJA5 stud set and locking catch. These accessories enable any of the UniJacks™ to be removable and are useful where a lack of space or theft is a problem. It also enables a number of items to be moved with just one set of UniJacks™ and sufficient sets of UJA6 keyplates
