Abstract

A folding crane, including ship deck, base column, slewing mechanism, column, hydraulic winch, hydraulic winch, main arm, main arm oil cylinder, luffing arm, luffing arm oil cylinder, auxiliary hook, main hook, its features There is a base column fixed on the deck of the ship, a slewing mechanism is installed on the base column, a column is installed on the slewing mechanism, the top of the column is hinged with one end of the main arm, and the other end of the main arm is hinged with one end of the luffing arm. An auxiliary hook pulley assembly is installed on the other end of the luffing arm, a main hook pulley assembly is installed in the middle of the luffing arm, and a main hook fixed pulley is installed on the side of the luffing arm opposite to the auxiliary hook pulley assembly. The present invention adopts integral slewing drive to reduce the height of the whole machine, and the door-shaped folding arm structure reduces the overall size and height of the whole machine, saves installation space, simplifies the structure of the crane, improves reliability, and can meet the requirements of larger cranes. Working range and lifting height, excellent performance, high reliability, convenient operation and easy maintenance.

Description

technical field [0001] The invention relates to a crane, in particular to a folding crane. Background technique [0002] Crane, also known as marine crane or marine crane, is a large deck machinery on a ship. It is a kind of equipment for loading and unloading cargo on ships. [0003] Conventional folding arm cranes take up a lot of space on the deck of the ship when they are retracted, and have a large radius of gyration during operation, which is easy to collide with the lifting load and interfere with the lifting load, which is troublesome to operate and high in cost. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a foldable gram crane, which adopts integral slewing drive to reduce the height of the whole machine, and the door-shaped folding arm structure reduces the overall size and height of the whole machine, saves installation space, The structure of the crane is simplified and the reliability is improve...
