Detailed introduction to the XCMG 25k5 crane on board the operation method

1, action

(1) the left hand: left and right is turning, forward is a small hook drop (pay attention to step on the foot pedal, you do not step on the foot pedal handle is no response).

(2) right hand: to the left is tilting the stalk, to the right is lying the stalk, before and after the big hook. (Note that any action must have to press the action switch, which is on the back of the handle, or you can press the switch on the control panel with the two-way slewing arrow to open it for a long time).

2, out of the culm

It is very simple, is the left hand or the right hand of the first yellow button, hold down the right hand inward (tilt culm) is out of the culm, the right hand outward is the retracted rod. When closing the car sometimes such as the reason for the limiter, can not turn off the key, because off the power off, so you can only press the forced to start hook up to the top lying back.

Extended information

Safety devices

1, lifting weight indicator (angle disk, also known as the weight limiters)

Installed in the root of the jib close to the driving position of the angle of the indication, which varies with the angle of elevation of the jib, reflecting the angle of the jib to the ground, know the angle of elevation of the jib in different positions, according to the Crane performance table and performance curve, you can know in a certain elevation angle when the amplitude value, lifting capacity, lifting height and other reference values.

2, over the winch limiter (also known as ultra-high limiters)

Installed in the end of the jib pulley block to limit the hook lifting height, to prevent the occurrence of over the winch accident safety devices. It ensures that when the hook rises to the limit position, it can automatically send out an alarm signal or cut off the power source to stop the rise, in order to prevent over-reeling.

3, moment limiter

The moment limiter is when the load moment reaches the rated lifting moment automatically cut off the hoisting or amplitude power source, and send out prohibitive alarm signals of the safety device, is to prevent overloading caused by crane instability limiter.

4, anti-jib tilting device and anti-back rod bracket

Anti-jib tilting device and anti-back rod bracket, when the jib lifts to the maximum rated angle of elevation, no longer lift the safety device, which prevents the jib from tilting backward when the angle of elevation is too large.

Lifting and hoisting

Lifting and hoisting "ten do not hang" regulations:

1, the lifting arm and the lifting of the weight of the following people stay or walk is not allowed to hang.

2, lifting command should be qualified by the technical training of full-time staff, no command or signal is not allowed to hang.

3, rebar, steel, pipe and other long and thin objects must be tied securely, multi-point lifting. Single head "jack" or tied not securely not allowed to hang.

4, porous board, ash bucket, hand-pushed dump trucks do not use the four-point suspension or large grinding plate hanging plate without unloading armor is not allowed to hang. Prefabricated reinforced concrete floor slabs are not allowed to double hanging.

5, hanging block must use safe and reliable block fixture, hanging brick must use brick cage, and stacked neatly. Wooden bricks, prefabricated embedded parts and other sporadic objects should be used to containers stacked securely, stacking is not allowed to hang.

6, floor, beams and other hanging objects standing on people are not allowed to hang.

7, buried in the ground sheet piling, well point pipe, etc., as well as adhesion, attached objects are not allowed to hang.

8, multi-machine operation, should ensure that the distance between the lifting of heavy objects is not less than 3 meters, in the same track multi-machine operation, no safety measures are not allowed to hang.

9, more than six strong wind area is not allowed to hang.

10, diagonally pulling the weight or more than the permissible mechanical load is not allowed to hang.
