A suspended platform kit has an elongate support 110 from which a platform is suspended and moved vertically using a winch, the support has a releasable bracket (fig.1,120) for attaching the support orthogonally to end of a lifting arm (fig.2,42,50), such as a crane (fig.2,40) or jib, which may be mounted on a vehicle (fig.2,10) so it is rotatable. Preferably, the support 110 is cylindrical and the releasable bracket is a trussed structure attached to the support 110 by a second bracket (fig.5,120A), which abuts a boom tip of the lifting arm, the releasable bracket may also have a pair of trusses 130A,130B attached using bolts 129B passing through holes 129A in the releasable bracket and the boom tip. Preferably, the winch has cable reels (fig.7,142A,142B) mounted on the support with pulleys between the cable reels and the ends of the support member, alternatively cable reels may be provided at the edges of the platform.
