The selection of pneumatic hoists should comply with the requirements for safe operation of lifting equipment. 

Employees have a responsibility to remain cautious and understand the correct methods and techniques for using pneumatic hoists based on their knowledge. 

Machinery and personnel should pay attention to product maintenance, and the ability to operate in this field is very important. 

The overall request includes: accurate and safe use of commonly used handmade items, as well as special items. To understand occupational standards or acceptable safety operating procedures. 

Top method: Cold drawn steel pipe is used as the cylinder, and the top selection includes welding convex holes and appearance There are some options for steel cylinders and lifting lugs, as well as for directly cast steel parts. The inner and outer surfaces of cast steel can remain unbreakable, such as air voids and cracks. 

Then, a method is used to process the outer surface of the inner hole of the above-mentioned method. Because the appearance of the request is not high, it is usually satisfactory to request casting components. The third method is to form a cold drawn tube after purchase, with a diameter of 170x5mm and an inner hole size of 160mm.

How to control the problem of load shaking of pneumatic hoists? Let's explain below:

It is not allowed to operate on the end side of the beam near the lifting load. 

The shaking of the crane can cause contact with people and objects or descent, leading to major accidents such as death or serious injury. 

If the load shakes and shakes harder, it will be difficult to operate the car and accompanied by danger. 

In principle, do not allow the load to sway horizontally. Therefore, please follow the following instructions. 

Horizontal movement, gradually starting without lifting the load sharply. 

When starting and stopping the lateral movement of the chain pneumatic hoist, even when the above operation is about to be carried out, the load can be relieved and it can still sway.

 At this point, if satisfied with the following operations, it will be possible to lower the swaying lifting load.
