Mobile Jib Crane Structural Features
Mobile jib crane, also known as mobile cantilever crane, is a cycloid reducer, rotating mechanism, column, control mechanism, base, chain hoist (or wire rope electric hoist), a pair of roller frame, counterweight, four wheel, as well as electrical equipment and other components.
Manually Mobile jib crane cantilever beam is rotated by the human, there are two needle roller bearings and thrust bearings as a support at the top of the column, the beam rotation is more flexible.
Electric Mobile jib crane cantilever beam rotation is through double stage cycloid reducer to drive a pair of gear, the top connecting plate, beam and reducer connected into one, through meshing between the river gear mounted on the reducer shaft and passive gear on the column top, drive beam rotation. During beam rotation, the relatively symmetrical pair of rollers roll in the column, more stable.
1. Control mechanism
The mobile jib crane traveling direction is controlled by rotating mechanism, through the joystick which is integrated with the wheel carrier, the joystick is slowly pulled in the required direction to change the running direction.
2. Operating mechanism
Electric mobile jib crane movement is driven by a single stage cycloid reducer drive wheels, the general speed is 15 m / min, due to the different wheel size, the speed is slightly different.
Manually mobile jib crane operating mechanism is no reducer driven, only by manpower to make the crane walk.
