WHAT IS THIS?
A tool that allows, in a visual way, the coordination and improvement of the tandem lifting operations.
WHY IS IT USEFUL?
It helps in load lifting when the weight is over the capacity of an indivitual crane, with special positioning and control requirements or with cargo turning where the load changes from one crane to the other.
WHAT CAN WE AVOID?
Overstresses in the lifting lugs, cargo displacement using basket hitchs, ocurrence of unstable equilibrium in the cargo and risk of crane inestability during operation.
A untied system, independent of the cranes, which allows for its use with any equipment.
