Product Description:

We could lift prefabricated girder with one450T gantry crane or two. As for 900t box girder, two elevators could be used.As for box girder of 450t or less, the elevator could be used independently. Itis attached with outrigger propelling, crown block and crown block hoistingequipments so that full directional and mechanized operation will beaccomplished. It can be principally used to hoist the precast girder from theprecast girder platform to storing girder platform. After the precast girder'smaintenance, it will be hoisted from the storing girder platform   to transporting girder vehicle. It canaccomplish the assembly and dismantling of bridge girder erecting machine.

According to differentworking conditions, there are 450t gantry crane for girder filed and for overline.

Q:Construction machinery, switch to do auto machinery, then can have a good development?
Is it necessary to do the automobile supporting work or the automobile tooling? Automobile tooling is a little similar to your construction machinery, but you need to be familiar with the standards, industry practices, etc. of the automotive industry, which requires a certain process
Q:What about the prospects for employment in machinery manufacturing and automation?
The profession mainly to the forefront of industrial production, engaged in the field of mechanical manufacturing design, manufacturing, scientific and technological development, application research, operation management and sales. Because of the importance and huge scale of the machinery industry, a large contingent of professional personnel is needed. In the future, mechanical personnel will still have greater demand. With the development of CNC talents will become the goal of all enterprises, mechanical design, manufacturing and processing professionals in recent years, the supply and demand ratio is also high
Q:What are the advantages of construction machinery?
In terms of machinery, but compared to machinery, mechanical engineering is more advanced
Q:What's the difference between an automatic watch and a mechanical watch?
The power source automatic mechanical watch is a shaking table, worn on the hand, people on the move is inevitably affected by vibration, the table has a collection, conversion to mechanical vibration rotational energy of the table, worn on the hand if it hasn't been tightened spring by the shock will be automatically wound, if you leave the table put in place without vibration generally within 24 hours it stopped. The disadvantage of this kind of automatic mechanical watch is that it is much thicker and thicker than the ordinary mechanical watch.
