Flexible use of mobile cantilever crane
The crane cantilever is hollow steel structure,with light deadweight,large span,large lifting capacity,and economic durability.Built in traveling mechanism adopts special engineering plastic traveling wheel with rolling bearing,which has small friction and is fast and easy to walk;The structure size is small,which is particularly conducive to improving the hook travel.
The cantilever crane is composed of column,slewing arm,cantilever drive device and electric hoist.The base at the lower end of the column is fixed on the concrete foundation through the anchor bolts,and the motor drives the reducer drive device to rotate the cantilever,and the electric hoist runs back and forth on the cantilever I-beam.
A large lifting height can also be obtained when the lifting clearance is very small.The electric cantilever crane is a light lifting equipment made to adapt to modern production.It is equipped with a highly reliable JPK chain electric hoist,which is especially suitable for short distance,frequent use and intensive lifting operations.It has the characteristics of energy saving,trouble saving,small floor area,easy operation and maintenance.
Mobile cantilever crane is more flexible and adaptable,and it is a necessary independent emergency hoisting equipment for automatic production line.With it,the production line can be kept unblocked.The cantilever crane of the curved boom series has the characteristics of novel structure,free extension and flexion,convenient operation and energy saving.During operation,press the button to lift the load,and use the bending and hanging movement of the beam to avoid objects in the control work area,so that the work area is large.You can reach any position in the work area by gently pushing and pulling with your hands.
The suspension control angle is 270 degrees,which can be matched with chain hoist,linear balancer,VPL slings,and the surface can be galvanized or painted.According to the different running tracks,the column type cantilever crane can be divided into two types:the internal hanging rail cantilever crane and the external hanging rail cantilever crane.It is used together with the PK type chain electric hoist.It can quickly and rapidly lift materials on the job.The column type cantilever crane can be installed at any position and is suitable for various occasions.It is an ideal choice for plants where other conveying tools cannot be fixed structurally.
The mobile cantilever crane is convenient to operate,reliable in performance,energy-saving,etc.,and is suitable for various industries.
When the mobile cantilever crane descends,it needs to rise first,which is not understood by many people.In fact,it is reverse connection braking,which is designed to prevent the inertia brake from braking when the heavy load of the crane descends,so this action is designed in the circuit.During operation,the controller shall be directly pulled to the right position when descending.When descending and stopping,it shall stop for 0.5 seconds in the reverse brake gear to achieve good braking effect.
During the use of the cantilever crane,attention shall be paid not to diagonal pulling,which will cause the equipment to roll over,causing economic losses and serious consequences.Overload is strictly prohibited during heavy lifting.
