Marine deck crane

Abstract

The invention discloses a marine deck crane comprising a base. Side support beams are arranged on the two sides of the base, the inner wall of the base is provided with a power device, the base is provided with a tower body, the base and the tower body are connected through a slewing bearing, the slewing bearing and the power device are connected to each other, an operation room is arranged in thetower body, a lifting control device is arranged at the bottom of the inner wall of the tower body, a lifting winch is arranged on one side of the tower body, a lazy arm is hinged to the other side of the tower body through a locking pin, the lazy arm and the lifting control device are connected, the other end of the lazy arm is provided with a second pulley device, the top of the tower body is provided with a first pulley device and an electric slewing reduction box, the lifting winch, the first pulley device and the second pulley device are connected through a steel wire rope, and a liftinghook is arranged below the second pulley device. The marine deck crane is simple in structure, the occupied deck area is small, operation and control are simple, and many special engineering operations can be realized.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a marine deck crane. Background technique [0002] The marine telescopic crane is a kind of marine lifting machinery. The marine crane is a special crane that performs transportation operations in the offshore environment. It is mainly used for the transportation and transfer of goods between ships, marine replenishment, and the launch and recovery of underwater operating equipment. And other important tasks, some cranes occupy a large area. At the same time, during the lifting work, because the crane ship and the receiving ship will pitch, roll and heave with the waves, these movements will cause the load to swing, which will cause the wire rope to deviate. , The phenomenon of de-grooving makes the crane unable to work normally and affects work efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a marine deck crane to so...
