Abstract

The invention provides a marine telescopic crane which is simple in structure and convenient to operate, can realize flexible lifting, is suitable for the lifting working conditions of different working radiuses, effectively avoids the phenomenon that a steel wire rope deviates and jumps out of a groove, improves the working efficiency and the use safety, and has high use and popularization values. The marine telescopic crane comprises a base fixed on a deck, wherein a tower body is mounted on the base through a slewing bearing; a basic boom is hinged to one side of the top of the tower body; a hydraulic winch is mounted at the upper end of the basic boom; a telescopic boom is mounted in the basic boom; a pulley device is mounted at the end part of the telescopic boom; one end of the steel wire rope is connected with the hydraulic winch; the other end of the steel wire rope bypasses the pulley device and is connected with a lifting hook; a first fixing piece is arranged on one side of the lower part of the tower body; a second fixing piece is arranged at the bottom of the basic boom; and a derricking oil cylinder is mounted between the first fixing piece and the second fixing piece.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a marine telescopic crane. Background technique [0002] A marine crane is a large deck machinery on a ship, and it is a device for loading and unloading cargo on a ship. General-purpose hydraulic cranes installed on tugboats are mainly used to lift daily necessities and garbage, while cranes equipped on ships often have lifting operations with different working radii, especially for cargo lifting on small and medium-sized ships. It is not particularly convenient. 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 and fall out of the groove, causing the crane to It cannot work normally and affects work efficiency. Contents of the invention [0003] In view of the above problems, the present invention...
