QD type hook bridge crane is a car gm bridge crane, crane on the workshop crane beam support track in the direction of vertical movement and lateral movement of the car and the rise and fall of hook to implement workflow, common weighs 5-50 t, working-level A5 - A7. Manipulation with ground control, the control room control, remote control three forms for the user to choose from. A5 level is suitable for the heavy work degree is not high general mechanical processing and assembly workshop, metal structure workshop, mechanical maintenance workshop, etc.; A6, A7 is suitable for the job more frequent or continuous production or continuous handling of the situation, also can be used as metallurgy and foundry shop help lifting; The use environment temperature in the 20-40 ℃, relative humidity of 85% or less; Another A7 level in quality inspection of lifting weight less than 50 t do, [2007] 2007 date file about new factory installed under the condition of the lifting crane requirements of molten metal can be used for metallurgy and foundry crane molten metal, the use of the environment temperature is 20 ~ 60 ℃. This crane outdoor use shall be indicated, in order to form a complete set of rainproof device. Advantages: high working level, stability, good security, low fault rate and speed parameters according to user requirements to design corresponding changes. Weakness: the order cycle is long, the price is higher, the dimensions is opposite bigger, require relatively large factories reserved installation size.

　　This product specification is the method such as the following:

　　(1) ground controlling
