Counterweight block and assemblies for cranes

摘要

A counterweight block (100) includes in at least one side thereof an indentation (120) from a top of the counterweight block (100) to a depth more shallow than the thickness of the counterweight block (100), the indentation (120) defining a lip (150) for hand grabbing. A stack of counterweight blocks (100) includes a plurality of indentations (120) formed in a side thereof as in a pattern for climbing up the stack of counterweight blocks, each indentation (120) having a lip (150) at a bottom thereof to act as a hand hold for grabbing and the indentations (120) usable for stepping while climbing. A crane (10) includes a counterweight tray (33) and a stack (84) of counterweight blocks (100) supported on the tray (33) to provide counterweight to a load of the crane (10), each counterweight block (100) including an aperture (158) through the counterweight block (100), and a retaining strap (164) threaded through each aperture (158) of the stack (84) of counterweight blocks (100), wherein the retaining strap (164) is secured to the counterweight tray (33).
