Safety and performance optimisation of industrial cranes
Hoisting of equipment and goods in production or in transportation is a common function across all heavy industries, performed by cranes. And the drive to improve safety in working conditions and efficiency in operations mean that cranes increasingly contribute to improve heavy industries.
Some of the most common industrial cranes are overhead travelling cranes and gantry cranes. In these cranes the load is suspended from a gripping device by cables, and acts like a pendulum. These swaying loads are a safety hazard and place additional stress on the crane structure. The sway control solution is to regulate the motion closely using an AC drive on the input to the electric motor.
