TECHNICAL DATA SHEET - BOTTOM BLOCKS

Bushman Equipment crane bottom blocks are designed to service your specific application. Sheave configuration, capacity, special control requirements and unique reeving patterns can be included to improve your crane operation.

 

The motor driven 360° rotating crane hook permits the crane operator to position heavy or awkward loads in less accessible work areas.

 

Standard non-motorized bottom blocks are available for retrofitting or modernization projects or can be manufactured in larger quantities for new crane installations.  All Bushman bottom blocks are designed and manufactured in accordance with CMAA Specification numbers 70 and 74 and A.I.S.E. Spec. 6.
