With the rapid development of modern science and technology, the expansion of industrial production scale and the improvement of automation, cranes are used more and more widely in the process of modern production, playing an increasingly important role, and the requirements for cranes are also getting higher and higher. below Huai'an crane rental We will introduce the application of crane in modern production process!
The container gantry crane has a larger span and a higher height on both sides of the gantry than the container cross car. The lifting speed is 8-10 m/min; In order to meet the transportation needs of port terminals, this crane has a high working level.
By use:
1. Container gantry crane is used for container terminal. Container unloaded from the ship by the quayside container carrying bridge with trailer
2. The gantry crane of the hydropower station is mainly used to lift and hoist the gate, and can also be used for installation. The lifting capacity is 80-500 tons, and the span is small, 8-16 meters; The lifting speed is low, 1-5m/min. Although this kind of crane is not often lifted, once used, the work is very heavy, so the work level should be properly improved.
3. Rail mounted gantry crane
This kind of crane mostly adopts box type and truss structure, and is most widely used. It can handle all kinds of articles and bulk materials, with a lifting capacity of less than 100 tons and a span of 4-39 meters. The ordinary gantry crane with grab bucket has a higher working level. Ordinary gantry cranes mainly refer to hook, grab, electromagnetic, hoist gantry cranes, as well as semi gantry cranes.
4. Shipbuilding gantry crane
It is used to assemble the hull on the slipway. There are always two lifting trolleys: one has two main hooks and runs on the track of the flange on the bridge; The other one has a main hook and an auxiliary hook, which run on the track of the lower flange of the bridge to overturn and hoist large hull segments. The lifting capacity is generally 100-1500 tons; The span is 185 meters; The lifting speed is 2-15m/min, and the inching speed is 0.1-0.5m/min.
After being transported to the storage yard or rear by rail gantry crane, the container gantry crane will stack them or directly load them and transport them away, which can speed up the turnover of the container bridge or other cranes. The yard can be used for stacking containers with height of 3-4 layers and width of 6 rows, generally tire type or rail type. The span is determined according to the number of container rows that need to be crossed, and the maximum is about 60 meters, corresponding to the lifting capacity of 20 feet, 30 feet and 40 feet long containers, which are about 20 tons, 25 tons and 30 tons respectively. In particular, the wide application of electronic computer technology has prompted the emergence of many interdisciplinary advanced design methods, and promoted the improvement of modern manufacturing technology and testing technology.
The fierce international market competition also increasingly depends on the competition of technology. All these promote the technical performance of cranes to enter a new stage of development.
