Secured by MotoSuiveur®

Any hoist can be an inherently safe hoist.

Any hoist. Any manufacturer. Any configuration. MotoSuiveur® retrofits them all into inherently safe systems. Your existing equipment, transformed.

Why MotoSuiveur® ?

Eliminate lifting risks in one. fell. swoop.

Integrating a MotoSuiveur® Solution is a uniquely efficient way to de-risk your lifting operations. The key to this efficiency is the safety-first design.

Risk elimination
