The ship building gantry crane can be single girder gantry crane and double girder gantry crane. When it comes to large span and lifting weight, we suggest the single girder gantry crane for ship building which is more economy.
The single girder gantry crane for ship building is mainly composed of steel gantry frame, upper trolley, lower trolley, trolley travelling mechanism, maintenance, lubrication, elevator and electric equipment. And there are rail clamp device (or wheel actuator), anchor device, lifting weight limiter system, wind speed and direction system, limit switch of each mechanism, and the other safety protection device for this crane. The deviation rectifying system can be equipped in case of very large span.
Weihua has rich experience on the manufacturing of gantry cranes for ship building with big lifting weight, lifting height and span.
On June 18, the signing ceremony of the strategic cooperation between Weihua Group and Shanghai CITI-RAISE Construction Group was held in Weihua Group. Weihua Group Chairman Han Hong'an and Shanghai CITI-RAISE Construction Group Chairman Wang Jilai signed a strategic cooperation agreement and held discussions on behalf of both parties.
Han Hong'an extended a warm welcome to the arrival of Shanghai CITI-RAISE Construction Group Wang Jilai and the delegation. Han Hongan said that Weihua Group and Shanghai CITI-RAISE Construction Group are both excellent national enterprises, taking root in different industries and sticking to different fronts to make corresponding contributions to the revitalization of national industries. As a national benchmark for prefabricated construction, Shanghai CITI-RAISE Construction Group has also made certain achievements in the research and production of prefabricated construction cranes and PC production and hoisting equipment. I hope that the two sides will take this opportunity to further cooperation and exchange in the field of assembly-type construction cranes, PC production and lifting equipment research and development, resource sharing, complementary advantages, and a win-win cooperation.
Wang Jilai said that as the concepts of green building, energy saving and environmental protection gradually heat up, prefabricated buildings and industrialization of buildings have gradually become an industry trend. Weihua Group, as a leading enterprise in the lifting industry, has outstanding comprehensive advantages in assembled construction cranes, PC production and lifting equipment. It hopes to combine the strategic layout of the assembly industry. The two parties are involved in assembly construction cranes, PC related production and lifting equipment. We should strengthen communication in design optimization, R&D and production, and comprehensively open a new chapter of cooperation.
Long Hongxin, general manager of Weihua, introduced Weihua's product advantages and technical characteristics in serving prefabricated buildings and PC production lines from the aspects of Weihua Group, assembled construction cranes, PC production line equipment, performance and cooperative manufacturers.
The strategic cooperation agreement stipulates the relevant measures for deepening the cooperation between Weihua Group and Shanghai CITI-RAISE Construction Group. In the future, the two parties will focus on the content of the strategic agreement in the design optimization, R&D production and market development of assembly-type construction and PC-related production and lifting equipment.
Before the symposium, Wang Jilai visited the Weihua Intelligent Industrial Park, Weihua Intelligent Parking System, 60,000 square-meter heavy lifting equipment manufacturing workshop, Weihua Big Data Center and Weihua Exhibition Hall, and learned about the technology of Weihua Intelligent Industrial Park in detail, the advanced nature, the applicable field of Weihua intelligent parking system, etc.
This video shows the whole production process (Email: weihua@craneweihua.com) of capacity 320t overhead crane for casting use. It is a Weihua product. This crane is the largest overhead crane produced in Henan Province, China, which is designed with 4 girders and 6 rails.
Rail mounted container gantry crane (RMG crane) is mainly used to load, unload, move and stack containers in railway transship fields and large container storage yards. It is constituted by main girder, rigid and flexible outriggers, trolley travel mechanism, lifting mechanism, crane travel mechanism, electric system and operation cab.
This rail mounted container gantry crane can be 3 kinds based on operating type in storage yards: whose girders outreach at the direction of the single outrigger is called single cantilever crane and at the direction of the double outrigger is called double cantilever crane, and whose girders do not outreach is called non-cantilever crane. Users can choose different types depending on the different demands of yards, storage and transport ways of containers and vehicles (trucks or railway vehicles).
Features of Rail Mounted Container Gantry Crane:
1. Low lifting speed because of low lifting height. High crane traveling speed fits the requirement of the long-track containers storage yards' productivity. The spreader would go over the fourth/fifth container layer when the stack of containers is three/four layer and its lifting height depends on the requirements of storage yards
2. The trolley traveling speed depends on the span and the outreaching distance of both sides of the bridge. In the case of the span and outreaching distance is short, smaller trolley traveling speed and the productivity is advisable; otherwise, the trolley traveling speed could be accordingly increased to meet productivity requirement.
3. When the span is over 40 meters, the crane mechanism travels in a high speed, and both sides of outriggers would deviate because of the drag on each side is different. So there is a stabilizer equipped on this crane and electric system would keep both sides of traveling mechanisms synchronous.
4. Electrical drive-control system adopts thyristor speed regulating drive AC or DC control system to meet the higher need and accomplish a better performance of speed regulating and control. Or it adopts conventional AC eddy current speed regulating control system and AC stator voltage and speed regulating drive control system.
An electric braking that equipped with thyristor speed regulating drive AC or DC control system or AC stator voltage and speed regulating drive control system is usually used as the electric control system of a high speed crane traveling mechanism. Conventional AC eddy current speed regulating drive control system which depends on the brakes to shut down traveling mechanisms should be avoided in order to prevent the huge impact to whole crane.
