Model Number: QE7.5+7.5t-23m-#3032
Key Specifications/Special Features:
Double lifting mechanism overhead crane for lifting telegraph poleDouble trolley electric overhead 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 40°C (not the high temperature).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 reducerImported 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 and more.
The electric appliance adjusts speed without contact or spark module
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%.
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 and more. 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.
Technical introduction:
1)Cabin control or pendant control.
2)Driver’s room is opened or closed types.
3)Wound rotor motor is used on each mechanism, changed speed by resistance.
4)Working ambient temperature: -20 °C-+45°C.
It’s not suitable for lifting blazing & melting metal or toxicant as well as explosion-proof or insulating working conditions. Tow dollies can work by myself or together.
Other configuration user can choose:
1)Changing speed brake: pole changing control, frequency control and more.
2)Linkage console let the driver room compact.
