ABSTRACT
This chapter discusses several types of cranes and learn how to use manufacturers’ literature to select the appropriate type and size for specific construction tasks. Crane accidents tend to be very costly in terms of equipment losses, usually involving damage to property and injuries to workers. In addition, the riggers who rig the load and fasten it to the crane hook block must be properly trained on setting up the crane to lift a specific load. There are a wide variety of slings available to riggers for attaching a load to a crane hook block. The most powerful, carefully rigged crane is only as strong and stable as the surface upon which it stands. Mobile cranes require level, firm, and drained working areas. Hydraulic cranes are manufactured in two basic types, both with telescopic self-contained booms. Hydraulic cranes move loads vertically by raising and lowering a hook mounted on a cable and horizontally by swinging the upper structure.
