Hand hoist is a small short distance lifting equipment, can be used in a variety of environments, small today will tell hand hoist in the underground use must be careful of several matters.

Why do you use a hand hoist in a mine? It is easy to carry and easy to operate. Can assist the use of personnel to transport the contents of the well to the land, save time and effort. However, the underground use of hand hoist is not quite the same as the ground use. Due to the special underground use environment, the space is generally narrow and there are many uncertain factors. Accidents may occur at any time if not handled properly.

So how can the hand hoist be used underground?

Hand-drawn hoist underground operation

The first of course is the hand pull gourd well before the use of the inspection work.

1. Check the handle itself. All parts of the hand-pulled gourd should be in good condition before it is put into use. If it is found, for example, that the shell is deformed, there is abnormal sound, the parts are loose, and the chain hook is cracked, it cannot be used.

2. Check whether the fixation point of the hand hoist is reliable. The hand hoist should be fixed effectively before it can be put into use. Otherwise, if the hoist in the lifting falls off and falls into the underground, it will cause a serious accident.

3. Check whether the hand-drawn calabash is in good condition after fixing it, so as to avoid accidental damage to the hand-drawn calabash due to collision or improper operation when fixing the hand-drawn calabash.

4. Inspection of downhole environment. Underground use hand pull calabash originally space is narrow, daylighting is also poor, should ensure the use of hand pull calabash space. Clean up the downhole environment as much as possible. Do not appear debris accumulation and other circumstances.

Secondly, the matters needing attention when the hoist is used underground

1. The hand hoist should be tested on the ground before being used underground. Ensure that the hand-drawn hoist is in good condition before it can be used in the underground

2. See clearly the load of the hand hoist and do not overload it

3. When the hoist is hoisted underground, no one can stand around the weight.

4. Make sure that one hand hoist is used to lift an item. It is forbidden to hoist multiple hand-drawn gourds at the same time.

5. When lifting heavy objects by hand, it is forbidden to leave the heavy objects in the air for a long time.

6. Clean up the hand-drawn calabash in time after use. Because the underground environment is relatively wet, there will be water vapor staying on the hand-drawn calabash for a long time. Avoid hand - held gourds from rusting.
