The new 360Â° rotating hand chain guide allows hoist operations from various angles. The operator is no longer directly within the danger zone beneath the load. The flexibility of the hoist allows the operator to work directly above the load.
Completely corrosion resistant units with either zinc-plated or stainless steel load chains should be used in all conditions with increased requirements for corrosion protection.
All models of the Yale lift Vario programmer can be provided with the following optional features for additional protection against sparking. Load and hand chains from stainless steel, units completely corrosion resistant, bronze-plated suspension and load hooks, solid bronze trolley wheels, rubber buffers chain containers.
The overload protection device of the Yale lift Vario program reliably prevents excessive load take-up of the hoist during operation. When reaching the pre-set overload value, the unit will jam and stop operation in the lifting direction. Lowering of the load is still possible at any time. The overload protection device provides additional safety with regard to possible false estimation of the load weight and thus increases the lifetime of the hoist.
