Free-standing electric mast(load is

This series of masts adopt trapeziform screw. The state of raising and falling is balanced and reliable. Can lock and work at any place.

Adopt cannulas with quadrate section which possesses good oriented, flexural and torsional capability.

There is linkage mechanism between every two mast bodies. Time for raising or falling is short. Can electric or manual operate. And manual operation is convenient.

There is a precision positioning mechanism when ascending or descending, which eliminates the gap between the cannulas and can guarantee the oscillation and torsion be minimum when the mast is up to the place.

There is rubber seal ring between the mast body, which has good waterproof, good sand control performance and de-icing performance. There is a layer of coatings inside and outside of each cannula which can protect the mast. There is a paint layer on the outer surface of the mast to protect it. So the three proofing performance working in the long-term field is good.

Because of excellent rigidity and strength, the mast can work for free-standing. So there is no use for guying rope which can consumedly reduce request of using position and economize on manpower.

The mast equipped with wire frame, crank and other accessories. The position of the crank can be chosen according to user's need. The installation size on the top flange can be customized according to user's requirements.

At present, the electric mast is divided into standard mast and intelligent mast. The standard mast has functions such as ascending, descending, stop and providing upper and lower position signal and other basic functions. The installation and overall dimensions of intelligent mast are the same as standard. The main difference is in control. The intelligent mast can provide such function as high display (display precision is 100 mm), fault alarm, CAN bus, RS485 serial ports, signal output, fault storage etc..
