Vsakodnevna izmenjava znanja – Strukturne značilnosti protieksplozijsko varnega električnega enonosilnega žerjava

The ex-proof overhead crane is designed and manufactured according to the standard JB/T10219-2000. It is used with B, BM, BCD, BM and other types of electric hoists to become a rail-operated light and small crane. Its applicable lifting capacity is 1~ 10 tons, applicable span 7.5-22.5 meters, working environment temperature within the range of -20℃-+40℃.

(1) Metal structure part:
The main beam is made of U-shaped channel steel rolled from steel plates, and then welded with I-beam steel to form a box-shaped solid web beam. The cross beams are also made of steel plates rolled into U-shaped channel steel, and then assembled and welded into box-shaped cross beams to facilitate storage and transportation. , the main beams are connected together with M0 bolts (high strength bolts).

(2)Sevencrane ex-proof overhead crane wholesale:
The explosion-proof electric hoist can lift and lower heavy objects and move longitudinally along the main beam.

(3) Operating mechanism:
Explosion-proof electric single-girder crane adopts separate drive mode. Driving and braking are accomplished by top choice for industrial ex-proof overhead crane. The transmission adopts “one open and one closed” gear transmission, and its closed gear part is borrowed from 5 The reducer of the trolley part of the ton hoist.

(4) Electrical equipment:
The operating motors used in european standard ex-proof overhead crane suppliers include single-speed and double-speed explosion-proof conical rotor motors (for operating speeds of 10 and 20 meters per minute. Other special speed requirements can be specially designed for users). Depending on the form of control, There are two kinds of electrical controls. The electric hoist and the entire crane are equipped with safety devices, such as lifting limit switch, end limit switch, etc.
