Abstract

A lifting jacking system comprises a pair of jacks connected by a cross bar 6, and each raisable by a jacking arm 5 to a desired height where it is self locking, a manual release being provided for lowering. Each jack has folding step supports (4 fig 1 not shown), to allow the placement of scaffold boards or similar planking, and the whole system can be positioned using lockable castor wheels.

Description

LIFTING JACK This invention relates to a Board Lifting device.
Fixing boards overhead is an awkward procedure tor one or two people. This invention allows a single operator to fix boards easilv, in less time and more accurately. The system comprises of two jacking devices and an interconnecting cross bar.
The jacking device compnses of two plates; one locking plate and one jacking plate assisted by springs.
A specific embodiment of the invention will now be described by way of example with reference to Figures 1 & 2.
Figure i shows a front view of the jacking system.
Figure 2 shows a side view Referring to the drawing, the lifting jack comprises a Main Frame I (fig. 2), a T-Bar (fig. 1.) a Jacking Unit 3 (fig. 2.); a Step Support 4 (Eg.l.): a Jacking Arm 5 (fig.'.) and a Cross Bar 6 (fig. 2.).
The cross bar 6 is inserted into step supports 4, until past locking button on either end of cross bar (the distance apart of the lifting units is adjustable to fit length of board).
The step supports 4 are folded down on which to place suitable platforms to work off.
The castors on the base of the Main Frames 1 should be locked to hold the device in position. A board is placed on the T-Bar 2, using both jacking arms 5, the board is raised to the desired position. Once fixed, the units can be lowered by holding the T Bar 2 and releasing locking plate and lowering manuallv.
