Abstract: The present invention relates to test weights for testing the load capacity of a crane. More specifically, the present invention provides a novel system and approach simple and efficient crane load testing using solid weights. Previous methods of testing crane load capacity often require significant time to configure and reconfigure the apparatus.

The system comprises a plurality of stackable test weights, and a lifting fixture specifically designed for the system. A cantilever structure located on two opposing sides of the test weight enables the lifting fixture to first be quickly secured underneath of said structure, and then lift that particular unit as well as any units surmounting that unit. A novel block lock system integrated into each weight unit enables self-alignment and securing of each weight as it is placed onto the weight stack.
