Many options to choose from to create a solid mount (fixed) overhead crane wire rope hoist. Features include two speed pole-change hoisting motors (1:6) with bi-metal sensor and hoist D.C disc brake, maintenance free; they have 4 step gear limit switches (up, down, low speed up approach, phase fault protection) provided with overload protection and variable speed travelling motors: 2 to 20m/min (for hoist with trolley) and the hoist electrics cubicle including low voltage transformer. The motor protection is rated IP55 with an insulation class of F.
A massive range of wire rope hoists for use in industrial overhead cranes. This type of lifting hoist do not mount onto a single girder crane bridge, they span between two girders with a pair of load wheels sitting on the top flange, hence the name double girder hoist. They are often used in higher capacity cranes with longer spans of crane bridge. Their other advantage is that the crane hook rises between the girders creating low headroom capability (very high raised hook position).
