This range of travelling trolleys enables Huchez-manufactured electric winches (TRBoxter or INDUSTRIA) to be used on jib cranes or on IPE, IPN and HEB-type rails.

The electric winch becomes mobile thanks to the integrated electric travelling trolley: the assembly, mounted on a rail, then moves horizontally along it.

Lifting and travelling of loads are thus made possible whenever a hoist cannot be used: lifting to very great heights in industry and construction, high lifting speeds are required, or where specific installation constraints (limited headroom, etc.) or usage requirements (equipping scientific research vessels to launch probes at sea, lifting platforms in a zoo, etc.) must be met.
