Evaluation of Load-Indicating Devices (LIDS) for Mobile Construction Cranes.

摘要

Load- and boom-angle-indicating devices and load moment computers for construction cranes are generically termed load-indicating device systems (LIDS). Several of these systems were laboratory tested to evaluate them for compliance with Society of Automotive Engineers (SAE) performance standards. Testing included calibration of the load or angle sensor and operation of the systems at temperatures between -50 and +150 F(-45.6 and 65.6 C). Results of the tests and an analysis of the data are presented. Functioning ability and accuracy of load-, angle- or radius-, and load-moment indicating systems were found to be satisfactory. (Author)
