Introduced: September 1968
Description
B66F covers residual hoisting, lifting, hauling, and pushing devices not classified under more specific subclasses (B66B–B66E), particularly those applying force directly to load surfaces without mechanical advantage systems. This includes vacuum lifters, magnetic lifters, friction-based movers, and similar force-application devices for material handling. The classification encompasses both manual and powered equipment designed for direct load manipulation rather than rope-and-pulley or chain-hoist mechanisms. Adjacent classes address elevators (B66B), cranes and derricks (B66C), and winches and capstans (B66D).
