IMPROVEMENTS TO SCAFFOLDING A gantry module which may be transported to a building site and simply placed on site to provide protection for pedestrians. Each gantry module is adapted to be secured to adjacent similar modules to provide a gantry assembly. In addition clamp means perform the dual function of securing adjacent modules and also securing a removable hand rail to the assembly. The modules are of generally rectangular form but may be of any desired shape and may include folding legs to enable transportation of a large number of modules. |
