An industrial lifting machine called Derrick
crane is generally used outdoors, like construction sites, ports and shipping
platforms. It is assembled at a fixed place and is characterized by its fixed,
lengthy tower. This crane is designed to move items from one fixed location to a
nearby location. The design of this crane has a base with a long steel pipes
and braces made tower. There are four independently moving lines and the fifth
line with a hook is at the end of the tower. The Derrick crane can be used in
the construction and repair of high-rise building as it can be used to lift and
lower items in a high location.
