Abstract
A system and method for connecting a removable counterweight system to a crane including a lower assembly adapted to be connected to the counterweight system, an upper assembly adapted to be mounted to the crane, and a latch block assembly mounted to the upper assembly. The latch block assembly includes a plurality of blocks cooperating together to form a central counterbore for receiving a stud therein. The blocks are mounted within the upper assembly by at least one axle to allow for rotation of the blocks. A distal end of the stud is removably connected to the latch block assembly to attach the counterweight system to the crane.
