Mobile cantilever crane Structural features
Mobile cantilever crane is also known as mobile jib crane, compose of cycloid reducer, beam rotating mechanism, column, control mechanism, base, chain hoist (or wire rope electric hoist), roller frame, counterweight, four main passive wheel, electrical equipment and other components.
The movement of the mobile cantilever crane beam can be either manual or electric, manual beam rotation is supported by two needle bearings and thrust bearings mounted at the column top, so that the beam can rotate more flexibly. Electric rotation Beam rotation is: a two-stage cycloid reducer drive a pair of gears, the top connecting plate, beam and reducer connect into one, through the movement between reducer drive gear and the passive gear on top of column, the beam will swing.
1. Control mechanism
The Mobile cantilever crane operation control direction is controlled by steering mechanism. Through the control rod integrated with the wheel carrier, the control rod is slowly pulled in the required direction to change the running direction.
2. Operating mechanism
Mobile cantilever crane movement is driven by a single stage cycloid reducer drive the wheel directly, speed is generally 15 m / min, due to the different sizes of wheels, the speed is slightly different. You can also rely on manpower to push the Mobile cantilever crane to move.
