Question

Why the cross section of crane hook is trapezoidal?

Answer 1

In heavy industries, Crane Hooks are one of the most important components to lift and shift heavy loads. It is used in warehouses, ports, construction and all other areas where heavy loads are handled. A Crane Hook is basically attached to a heavy chain or rope which runs over a pulley.

Crane hooks are available in different shapes, sizes and cross section such as circular, rectangular, triangular and trapezoidal and usually made of steel. These are used accordingly, depending on the load and lifting environment.

The Trapezoidal cross-section hooks are more common as it is able to absorb more vertical load and deflection. It is able to absorb and store more strain energy, thereby ensuring safety of the crane.
