摘要

The scaffolding can be fixed or mobile and mounted on a trailer (2). It consists of successive levels (3,4,5), the level (3) being hinged onto the floor (2a) of the trailer. It (4) is also hinged to the mobile end of level (3) with hydraulic or pneumatic jacks (10,11,12) raising each sloping level. The struts (15,16) can be locked in position and are hinged at points (16a) and locked at (3a). The trailer (2) is stabilised by side legs (22) which fold up during transport onto the sides of the trailer. Rigid or flexible guys (23) stabilise the various levels at the required height and are fixed to the ground or onto legs (22).
