Lorry Mounted Cranes ~ these mobile cranes consist of a lattice
or telescopic boom mounted on a specially adapted truck or lorry.
They have two operating positions: the lorry being driven from a
conventional front cab and the crane being controlled from a
different location. The lifting capacity of these cranes can be
increased by using outrigger stabilising jacks and the approach
distance to the face of building decreased by using a fly jib. Lorry
mounted telescopic cranes require a firm surface from which to
operate and because of their short site preparation time they are
ideally suited for short hire periods.
