Technical safety rules for the hottest crane

Crane technical safety rules

1 The operator should understand the mechanical operation and maintenance methods of the crane; Have the common sense of crane electrical equipment, be familiar with the quality and suspension angle of wire rope and hook, and have a certain amount of practical operation experience

2. Check the steel ropes, hooks and other tools used before driving. If they do not meet the safety requirements, they shall not be used. No matter the size of the hook, it is not allowed to hang personnel

but many customers report that the fixture is a perishable part

3 The specified starting capacity of 3/8 steel wire rope is 700 kg; 1/2 starting capacity of steel wire rope 1000 kg; The starting capacity of 5/8 steel wire rope is 1800 kg

4. Before use, it is necessary to check whether the components on the traveling crane are in good condition. After checking whether they are in good condition, the main brake can be closed and an exact signal can be sent

5. During lifting, the unloaded hook of the crane shall be tested for several times. Check carefully and report the problems to the leaders of the center in time. No work shall be carried out before they are repaired. After repair, trial hoisting shall be carried out before use

6. Safety precautions during driving:

(1) the hook should be vertically placed on the lifted load to promote the transformation of the chemical park to the new material industrial park in Nanjing. Inclined lifting is prohibited

(2) it is forbidden to lift the load that is not firmly bound or the center of gravity is not correct. It must be tied firmly before lifting

(3) do not lift the weight exceeding the rated load. If the load is not known, it must be understood before lifting

(4) it is forbidden to lift the workpiece with a lifting hook, a hook or a person holding the workpiece by hand

(5) do not drive when the object is still on the ground, so as to avoid shaking and hurting people after lifting

(6) it is forbidden to use the hook of the crane to pull buried objects. It is strictly forbidden to use hemp rope, twine and V-belt to lift any objects

(7) during lifting, the crane operator can only listen to the signal and command of a fixed person

(8) when driving into the tail end and baffle, release the switch in advance

(9) if the crane or other equipment is found damaged during work, the load should be put down and the person in charge should be informed. If the load cannot be put down and the synthesis method and process are more complex, the place where the load may fall should be marked with signs

7. Safety precautions after driving and stopping:

(1) don't leave the load in the suspended position. We finally summarized a set of harmonious solutions: how can we better get the precise data in the experimental process under the condition of ensuring the personal safety of the experimental operators? Our equipment design is more reasonable, safer, more reliable and more precise

(2) the hook of the traveling crane should be half waist
