The equipment operation workers are carried out at the end of each week. The maintenance time is: general equipment 2h, fine, large, thin equipment 4h. 1.Before lifting operation, it is necessary to carefully check the binding and hooking of the lifting object, especially for the heavy and bulky heavy goods that should be heavy. It should be checked again whether the pulley group magnification is appropriate, the condition of the counterweight and the brake, etc.; for the pulley group after changing the magnification, the axis of rotation of the hook must be kept straight up from the ground.
2. When the lifting heavy object reaches more than 90% of the extra lifting weight, two or more operation actions must not be performed together. When the weight of the lifting object reaches 50% of the additional lifting weight, the low gear should be used.
3. When lifting goods, the working radius will be increased due to boom deformation. Therefore, when lifting a heavier item, it should be lifted from the ground first, and then check the brake, the tie rope, the stability of the whole machine, and the conditions of the legs. The suspicious appearance was found to be heavy. After careful inspection, the lifting operation can be performed.
In the process of lifting, if it is felt that a small crane is approaching and tipping over or there are other risks, the heavy object shall be immediately dropped to the ground, and the lifting work shall be carried out again only after adopting safety measures.
4. Plan a small crane with a fast and slow hoisting machine. Only speed is allowed during the race and rapid lifting is prohibited.
5. Even if the mini-crane is equipped with an anti-overwind device, care must be taken to avoid the appearance of over-rolled appearances. During operation, attention should be paid to the alarm movement of the overcoil. If the alarm should stop the lifting operation of the hook, the rope will be broken and the heavy object will fall.
6. When the lifting object has a small mass and a large height, the power can be improved by means of throttle throttle and dual pump confluence.
7. When the small crane device components or equipment will be in place, the engine should be operated at a low speed, single pump oil supply (large and medium-sized cranes), saving speed and other methods to perform jog operations.
