| Abstract |
A review of 8 accidents (5 fatal ones) in l978-82 showed that all but 1 were due to collision of the boom of the lower of 2 neighbouring tower cranes with the rope of the higher crane. Such collisions can be avoided by equipping the cranes with devices to limit the rotation of the boom of the upper crane and/or the travel of the hoist crab along the boom so that the rope of the higher crane can never enter the circle of operation of the lower crane. Greater flexibility can be achieved by (1) having a supervisor in constant communication with the crane operators, or (2) having the travel-limiting devices on the higher crane be controlled by sensors which detect the position of the lower crane; both alternatives permit the higher crane to operate in the circle of the lower crane when the latter is out of the way. Appropriate sensing and travel-limiting systems are described. |
