16t+16t Double Trolley Overhead Traveling Crane (QE)

1. QE double girder overhead traveling crane is the renewed product, which is an intelligent crane. Its structure is much more reasonable and its assembly and property is much superior. Lifting capacity is 5t-300t(Gn). And the span is 10.5m-35m. And working system is A3, A5 or A6. And ambient temperature no more than 40ºC(Not the high temperature). 

2. Technical characteristics: 

Lowest limiting size between the top of crab and the track of trolley, it reduces 20%~30% the capital of workshop efficiently. 
Hard-tooth reducer, 
Imported wire-rope
Trinity drive. 

Protecting devices: 
1. Alarm device to overloading, 
2. Obliquely hanging, 
3. Second protecting equipment preventing hook clashing the top, 
4. Protecting the current lacking of any phase etc. 

The electric appliance adjusts speed without contact or spark module, and

Fulfill converter function, including mini-speed and double speed, which make traveling and lifting very steady. 

The operating board(handle) adopts 12V or 36V safe voltage. The electric controlling can be used more than 2 million times when the voltage is 380V+5~ -10%. 

3. Choosing Principle: 

According to the working system and using field. Calculating the times per hour of starting and pulling-on recycle, you should mark the practical time per day and continuous time (h). When select or appraise, you should be sure such as field, all the limiting size, ambient temperature, speed, time(h), intermission or continuity, the times of starting and pulling-on per hour, etc. The speed of ground controlling should adopt A3 slow speed. The above mentioned is just for reference. Reasonable selection, design and match can increase the working efficiency greatly.
