QE overhead crane is designed to operate in the indoor workshop or outdoor for handling long materials. The double trolley can be lifted or run independently; when long items need to be lifted, the transfer switch on the console can realize synchronous lifting and synchronous operation.
This series of double trolley cranes meet the requirements of GB/T3811 “Crane Design Specification” and GB14405 “General Overhead Crane”, and is suitable for lifting and transporting long items (such as wind power towers, pipe piles, telephone poles, steel Molds, steel pipes, wood, paper rolls, etc.). After taking wind and rain protection measures, it can be used in the open-air environment.
The normal environment used by this series of double trolley cranes is: the ambient temperature is -20°C~+40°C, the relative humidity is ≤85%, and the altitude is ≤1000 meters.
There are 5+5 tons, 8+8 tons, 10+10 tons, 20+20 tons, 32+32 tons, 40+40 tons, 50+50 tons, 100+100 tons, 130+130 tons, 150 +150 tons and other standard lifting weight, span 7.5-40 meters.
According to the degree of heavy use, this series of cranes are divided into two basic working levels: intermediate (A5) and heavy (A6). If necessary, they can also be designed and manufactured as light (A1~A3) or super heavy (A7~A8).
Intermediate working level (A5): The electric motor’s connection duration rate JC=25%, used in less frequent use occasions, such as paper-making workshops, steel pipe workshops, tower workshops, etc.
Heavy-duty level (A6): The motor’s power connection duration rate JC=40%, used in more frequent applications, such as pipe pile workshops, telephone pole workshops, etc. For heavy-duty cranes, the trolley operating mechanism and auxiliary hoisting mechanism are designed according to the intermediate level.
