Port cranes are a type of lifting equipment specifically used for cargo loading, unloading, and handling in ports. Usually, it has a large tonnage and operating height, and can quickly and accurately unload or load goods weighing between a few tons to hundreds of tons from the ship, and can be flexibly moved, suitable for cargo ships of different shapes and sizes.
Port cranes are widely used in port loading and unloading operations due to their efficient and energy-saving characteristics. The following will provide a detailed introduction to its function and purpose.
RMG Type Upper Rotation Rail-mounted Container Gantry Crane are mainly used for container loading, unloading, handling, and stacking in container railway rotating yards and large container storage and transportation yards.
In terms of time, they are mainly put into operation at container hub ports, using non cantilever, single cantilever, or double cantilever methods, which are determined based on the site, container storage and transportation process flow, and loading and unloading vehicles (container trucks or railway vehicles).
FEU Container spreader refers to a specialized crane for loading and unloading containers, which is connected to the top corner fittings of the container through the rotary locks at the four corners of its end crossbeam. The driver controls the opening and closing of the rotary locks for container loading and unloading operations.
Container cranes can be divided into four types according to their structural characteristics: fixed, master-slave, sub mother, and telescopic. On the basis of telescopic lifting appliances, rotary lifting appliances, double box lifting appliances, and movable double box lifting appliances have been derived.
UMG type Double beam gantry crane is an ideal handling equipment for outdoor operation. Cantilevers can be added on both sides of the main beam (usually the cantilever length is 1 / 4 of the span length), and the distance between straight legs can be increased to facilitate the passage of large goods from the straight legs.
The power supply can be provided by cables, sliding contact wires and diesel generators. Gantry crane has the characteristics of high site utilization, large operation range, wide adaptability and strong universality.
