Packing of STS Shore to shore container crane:
1. Electric parts are packed by high quality plywood crate to reduce distortion in conveying;
2. Main beams, end beams and electric trolley packed by plastic woven cloth, which can reduce abrasion during transportation.
Delivery of STS Shore to shore container crane;
1. If the size are suitable for container ship, usually by container;
2. Big size, usually by bulk ship or by container after truncation.
Quayside container cranes (abbreviation STS, QC), mainly composed of steel frame, luffting mechanism, inclination mechanism, crane travel mechanism, trolley traverse mechanism, machinery house, elevator, container lifting spreader, electrical equipments and other accessory equipments for safety.
According to different types of trolley, quayside container gantry crane has three trolley driving types as wiretow, semi-tow and motor driving. Qusyside container gantry crane could be provided with PLC system and CMMS automatic-fault monitoring and diagnostic functions, there is sufficient communication and lighting. The steel is divided into single, double box structure, the girder structure and H-type gantry structure.
Referenced standards: GB/T15361-91 quayside container crane technical conditions, GB/T15360-91 quayside container cranes test methods, GB6067-85 crane safety rules, GB3811-2008 crane design standards and ISO standards, FEM standards, JIS standards and so on.
According to the general rules of products, components, it forms the hoisting mechanism modeule, trolley traction mechanism module, trolley assembly module, steel structure module, founction module, general module and etc. The standard module production ensures product stability of quality and shortens the delivery cycle.
1) Advanced Manufacturing Technology
Steel shot blasting pretreatment, the surface quality reaches Sa 2.5 grade. Crane wheel and wheel shaft through the high frequency quenching and tempering treatment, it eliminates the internal stress and ensures the machining accuracy. WEIHUA pioneers the use of welding robot, the main girder inseam weld by advanced MAG welding. The main girder welding adopts radiographic testing and ultrasonic testing to ensure the welding quality.
YUFEI cranes have been used for wide range fields, such as Industry of machinery, metallurgy, electric power, chemical, military, railroad, water conservancy, shipbuilding, port and large scale storehouse, and so on. The crane series includes Gantry crane, overhead/bridge crane, shipbuilding crane, container crane, port crane, electric single beam crane,electric double beam crane & electric hoist, etc.
