Lifting machine

Abstract

The invention discloses a lifting machine. The lifting machine comprises a vehicle frame, a pitching mechanism and a vertical lifting mechanism; the pitching mechanism comprises a pitching suspension arm, and the pitching suspension arm is movably connected to the vehicle frame; and the vertical lifting mechanism is in transmission connection with the pitching suspension arm, and the tail end of the vertical lifting mechanism is connected with a lifting appliance. The lifting machine is provided with two power mechanisms, namely the pitching mechanism and the vertical lifting mechanism. The pitching mechanism is fixed after the amplitude of the pitching mechanism is changed to the maximum height, the vertical hoisting mechanism is switched to execute hoisting operation, energy consumption of the pitching mechanism is reduced, and 10%-30% of oil consumption / power consumption of hoisting operation of the hoisting box is reduced. Meanwhile, the pitching mechanism and the vertical hoisting mechanism are matched for operation, so that multi-row and multi-layer containers can be spanned, and full-elevation heavy container stacking operation can be carried out. The lifting machine is simple in structure, low in cost and capable of crossing multiple rows of containers to uncover and lift the target container, the uncovering process is simplified, the operation efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of hoisting equipment, in particular to a hoisting machine. Background technique [0002] In port terminals, railway cargo stations, and logistics container yards, container reach stackers are often used as heavy-duty container handling and lifting equipment. Ordinary reachstackers have the function of multi-row sequential hoisting and limited cross-row hoisting capacity, but none of them can carry out the hoisting operation of the container below the first floor of the cross-stack crane. It is even more impossible to carry out vertical hanging box stacking operations for 40-foot containers above the second floor and 20-foot containers above the third floor. In the railway container freight station, there are also requirements for cross-track hanging boxes and vertical lifting boxes, and conventional reach stackers often cannot meet these requirements. [0003] In addition, with the successful launch of la...

Problems solved by technology

If small yards use large-scale gantry cranes in large-scale automated docks for automated operations, the price of a single automatic gantry crane ARMG or ARTG is as high as 10 million or more, plus the cost of track and foundation construction, the cost of equipment alone will be as high as 12 million. , general customers cannot bear such a high cost of equipment procurement

[0004] With the popularization of logistics container network and fast demand, small container railway cargo stations and inland waterway shipping terminals are increasing year by year. If the construction requirements of conventional inland waterway terminals are followed, it is generally necessary to purchase small shore-to-shore bridge cranes (STS) for shore-to-shore The container loading and unloading of the ship is carried out, and at the same time, the front stacker or RMG is also purchased for container stacking operations. This kind of equipment configuration scheme, the total purchase cost of the equipment alone is as high as 12 million or more
