Abstract
Abstract A crane operating aid comprises a load moment computer and a number of transducers which monitor crane parameters such as boom length, boom angle, and boom reaction forces. The computer then calculates the percentage of load capacity as a function of the crane manufacturer's published load rating tables. The computer is disposed near the crane operator to facilitate interaction between the two and actively solicits crane condition information from him through a prompting scheme which initially poses a series of status requests to the operator. The operator must supply appropriate responses to the status requests prior to operating the crane. The computer also can display any of the input parameters monitored by the transducers. A plurality of alarms of ordered urgency are provided which indicate various overlimit conditions. Both minimum and maximum operator controlled set points are provided. The series of prompting crane status requests can be repeated automatically such as with each start up of the crane or at the operator's option such as when a change of crane status occurs during operation. The crane operating aid is easily adapted to use with lattice or telescoping type cranes.
