Abstract
A ladder attachment includes a telescopic cross-bar 1A, 2A the ends of which carry wheels 3A for engaging a wall on either side of the ladder. This provides stability and also sets the ladder back from the wall. The center portion 1A of the cross-bar has a pair of hooks 4A which hook over a rung 5A of the ladder and a pair of turnbuckles 9 which hook under a lower rung 12 (after which the turnbuckles 9 are tightened to secure the fixing). The turnbuckles are attached to a sleeve 10 carried by the bar 1A and have hooks 11. A platform assembly 30 can also be mounted on the ladder and connected to the ladder attachment by support struts. The platform assembly includes a support framework 32 in which slots 33 are provided to overlie two rungs 34 and a turnbuckle 35 tightens the framework against the ladder. The ladder attachment can carry a pulley by which goods can be hoisted to the person working on the ladder. The ladder attachment provides stability to the ladder and the platform, if used enables a greater area to be made available to the person on the ladder. A spacer (50-55) device can be temporarily mounted at the top of the ladder to space it from a wall and permit fitment of the ladder attachment to the ladder.
