Shore container crane (referred to as quay crane) is a specialized lifting equipment for loading and unloading container ships at the forefront of container terminals.Usually installed on the shore of ports and docks.
The shore container crane is mainly composed of an electrical control system, a metal structure, four major mechanisms (lifting mechanism, trolley running mechanism, pitching mechanism, and trolley running mechanism), a trolley assembly, a tilting and hanging compartment protection device, and auxiliary devices. Each institution adopts the unique technology of fully digital AC frequency conversion and PLC control speed regulation, which is flexible and high-precision in control. And equipped with various specifications of single box and double box container special lifting equipment, as well as optional electronic anti shake function. The large-scale development of container transport ships, especially the development of super Panamanian ship types, has put forward updated for shore container cranes: firstly, improving the technical parameters of container cranes, speeding up the speed parameters of container cranes, increasing the overhang and lifting height; The rated lifting capacity under the lifting device has been increased; The second is to develop and design an efficient shore container loading and unloading system to meet the requirements of container crane productivity for large-scale ships.
Tire type container gantry crane (commonly known as yard crane, abbreviated as RTG in English) is a specialized machinery used in large specialized container yards to load and unload standard containers. Often powered by diesel generators, but can also be powered by cable reels, lithium batteries, etc. It consists of a large vehicle mechanism, a small vehicle assembly, a gantry frame, a power system, and container specific lifting equipment.
Weihua RTG has diverse functions, high efficiency, stability and reliability, wide operating range, good maneuverability, low sensitivity to ground roughness, convenient use, maintenance and upkeep. Its biggest feature is that it can travel straight, horizontally, turn 0-90 degrees and rotate in place.The number of rounds is designed according to the requirements of the site's wheel pressure.
In terms of safety facilities, there are overload protection, diesel engine overspeed protection, signal devices for high water temperature and low oil pressure, wind speed indicators, anti typhoon anchoring devices, emergency stop buttons, and limit switches and signal indicators for various mechanisms.In addition, ZPMC can also choose DGPS (satellite automatic positioning system), ECMS, RCMS (fault display and communication system with the central control room), as well as large vehicle lifting devices and boarding elevators that facilitate large vehicle steering and reduce tire wear on RTG.
Equipped with comprehensive safety instructions and overload protection devices, it maximizes the safety of operators and equipment. Standard purchased parts from well-known domestic and foreign brands ensure the overall quality of the machine.
Rail type container gantry crane (referred to as gantry crane) is suitable for the handling and loading and unloading of international standard containers and railway wide containers in container yards or transfer stations such as ports, docks, railways, and logistics. Supported by multiple sets of steel wheels on the track, powered by mains electricity, it consists of a large vehicle mechanism, a small vehicle assembly, a gantry frame, a power system, container specific lifting equipment, etc. Small sensibility to unflatness of the ground.
The cross transport vehicle for containers adopts advanced sensing and monitoring systems, which can independently complete the automatic recognition of heavy containers, and can quickly and accurately complete the loading, unloading, transportation, and Stacking of containers, significantly improving logistics efficiency and reducing waiting and idle time of goods. Capable of stable operation in narrow tunnels and open storage yards. They also have good off-road capabilities and stability, and can work normally in changing terrain and climate conditions. Features such as strong overload capacity can effectively improve the safety and efficiency of logistics operations. Compared with the traditional tire crane with a climbing slope of 3%, the new generation of straddle carriers can achieve a full load climbing slope of 10%.
