Mast crane

Abstract

The invention relates to a mast crane. The mast crane comprises a front vehicle base, an operation arm, a rear vehicle chassis, a counterweight platform, a propeller strut front supporting rod and a propeller strut rear supporting rod, wherein the front vehicle base comprises a vehicle frame and a rotary table rotatably arranged on the vehicle frame; the bottom of the operation arm is hinged to the rotary table; the rear vehicle chassis is configured to be in contact with the ground; the counterweight platform is movably arranged on the rear vehicle chassis and connected with the rotary table; the bottom of the propeller strut front supporting rod is hinged to the rotary table; and the bottom of the propeller strut rear supporting rod is hinged to the counterweight platform. According to the mast crane, the rear vehicle chassis is arranged, and the counterweight platform is movably arranged on the rear vehicle chassis and connected with the rotary table, so that the counterweight platform can rotate around the rotary table on the rear vehicle chassis, heavy objects can move in the rotating direction, the operation adaptability is wide, and the application range of the mast crane is expanded.

Description

technical field [0001] The present disclosure relates to a mast crane. Background technique [0002] The statements herein merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] Cranes are mainly used for hoisting large-scale heavy objects. With the rapid development of industrial technology, large-scale bridges, docks, and port constructions have become commonplace. There are a large number of goods waiting for loading and unloading in ports, docks, and shores every day. Lots of cranes for work. At present, the cranes used in port terminals mainly include portal cranes, floating cranes (ship cranes) and conventional mast cranes. [0004] The height of the portal crane is high, it is troublesome to disassemble and assemble, it is not suitable for daily management and use, and its lifting capacity is small, so it is not suitable for hoisting of overweight parts; The cost is high; and the floating crane...

AI Technical Summary

Problems solved by technology

[0004] The height of the portal crane is high, it is troublesome to disassemble and assemble, it is not suitable for daily management and use, and its lifting capacity is small, so it is not suitable for hoisting of overweight parts; The cost is high; and the floating crane is greatly affected by wind and waves. When there is a large wind and wave, the floating crane must drive to the sheltered dock, resulting in a waste of resources and time; The requirements are high, and it occupies most of the space of the terminal, the cost of the terminal is high and the use occasions are limited
