What Types Of Cranes Are There?

Cranes can be divided into four categories: overhead mobile cranes, boom cranes, bridge or gantry cranes, and cantilever cranes.

The overhead mobile crane is composed of a beam and aerial lifting device. The crossbeam is supported by fixed rails and can move back and forth on the rails.The air lifting device is composed of a lifting device and other devices, and can move from one end of the beam to the other end. The beams and the frames connected to them are collectively called bridges. These cranes include weights from 2 tons to 400 tons and spans from 20 feet toVarious types of 150 feet. Depending on the purpose,Cranes working in the engine room are often controlled by bridges or aerial lifting devices,In other cases, the control device is often on the ground. When the two aerial lifting devices are installed, they can run on the same rail in parallel or staggered up and down,To ensure that each aerial lifting device can move on the entire beam.

Boom crane The boom crane has a tilt boom that can lift heavy objects on its outside.The boom is connected to the vertical frame by rope or other means. The boom can be fixed-length or telescopic.The crane can be stationary or mobile. Cranes in this category include: mobile and crawler cranes, Builders, dock cranes, tower cranes and mobile installation on high platforms, derricks,Buoys and cranes on barges.

The lifting capacity varies from 1/2 ton to 300 tons, and the boom can extend from a few feet to150 feet. Need to be in the shipyard,Port cranes handling heavy machinery and equipment are often installed on barges.
