ZZHZ—Service Quality is theKey Point As Cranes Face Problem of Oversupply
As infrastructure construction policy in our country is energetically implemented in recent years, the quantity demand on cranes also increases gradually and there are more and more crane manufacturers. As data display, China crane output from January to July, 2012 is 4725647.19 ton. With higher estimate on market needs, crane may face problem of oversupply in the coming years.

How to Use and Maintain the Moment Limiter?
ZZHZ should send technicians to train buyers? workers after installing the moment limiter; on one hand the production for users won?t be affected for common failures of instrument, on the other hand the manufacturer can reduce cost. Users should master the follows as receiving training:

How to Choose Proper Crane Moment Limiter?
Crane is equipment with higher construction risk, once the accident occurs, it may cause serious consequences such as casualties. So we must pay attention to safety issue of crane. Technicians from ZZHZ say correctly selecting and maintaining crane moment limiter will not only reduce or even avoid serious accident caused by overload, but also ensure safe work of cranes.

What are Girder Bridge Categories Told by ZZHZ?
So far, ZZHZ has told a lot of professional knowledge about bridge crane and launching gantry, but we know little about the construction facilities they are used in. Next let us introduce girder bridge categories to everyone.

Accidents Points for Launching Gantry in the Bridge Construction Process
To effectively prevent, timely control and eliminate the damage caused by sudden accident in the bridge construction process, reduce loss caused by the accident to a maximum extent, maintain interest of society and enterprise, ensure human and property safety, ZZHZ makes a series of measures to manage the launching gantry working.

What Factors Will Decide the Price of Launching Gantry?
The launching gantry is an equipment to install precast girder on prefabricated piers, making a huge contribution to bridge construction in China. With fast development of high speed railway, more and more launching gantry is widely used in the high speed railway construction. While price of launching gantry is quite different with larger fluctuation, why does it happen? Below is a simple analysis from ZZHZ:
launching gantry
- Different brand. Famous brand has better quality warranty, more considerate service and more guarantees compared with small factories. That makes a difference.
- Different type. According to different demands, each type for one customer group. Different needs, different type, then different cost leads to type difference.
- Old or new equipment. New equipment usually uses new technology and better spear parts which cause a rise of cost and expensive price. As time goes on and launching gantry prevails, the price will decline gradually.

What is cutting method for crane main girder deformation?
highway bridge construction crane
Under some conditions, ZZHZ cuts main girder upper cover plate by use of the influence that main girder self-weight has on the camber, thus reduce bending modulus of main girder section at cutting position, weaken bending resistance of main girder, generate a mechanical deformation caused by main girder self-weight, then reduce upper camber value at mid-span and increase up-warp value at cantilever end. It is easier to control the whole correction process and deformation degree by using the method, but we should mention that main and auxiliary web plates around cutting parts will cause a web plate wave out of tolerance caused by main girder axle rotary deformation vertical to web plate direction, which should be avoided.
