What is article 15 of crane operator's habitual violation?

During hoisting operation, it is very dangerous to stand under the derrick, under the hoisted object, in the area before hoisting the hoisted object, in the triangle area of the steel wire rope of the guide pulley, around the fast rope, and in the stress direction of the stay hook or the guide pulley, so it is extremely difficult to avoid the danger. Therefore, the position of the staff is very important. We should not only pay attention to ourselves at all times, but also remind each other and check the implementation to prevent accidents.

2. Correctly understand the safety factor of slings.

In hoisting operation, workers often use ropes as the foundation without correctly understanding the safety factor of slings, which leads to overweight operation and is always in a dangerous state.

3. Foresight of various factors

In the demolition operation, we must foresee all kinds of factors, such as the estimation of the weight of the object, the thoroughness of cutting, the increased load of the demolished parts due to extrusion, and the forced lifting of the connecting parts without inspection.

4. Put an end to misoperation

Lifting operation is different from many buildings, which involves a large area and often uses different equipment and different types of cranes. Factors such as daily operating habits, differences in performance and command signals can easily lead to misoperation, so be especially cautious.

5. Fasten the suspended object firmly.

When lifting and disassembling at high altitude, the hoisted object should be "locked" instead of "pocket"; Measures should be taken to "buffer" the sharp edges and corners of suspended objects.

6. The drum rope is not tight

When lifting and disassembling large pieces, the wire rope wound on the drum of crane or electric hoist is loosely arranged, which causes the fast rope under heavy load to be pulled into the rope bundle, which makes the fast rope violently shake and extremely unstable. Therefore, it is usually dangerous to continue working and not stop.

7. No-load slings accidentally hook objects

Many accidents happen in this way. The promotion work has been completed. When the hook runs on the empty rope device, the sling in the free state pulls the lifted object or other objects. If the operator or commander does not respond in time, the accident will happen immediately, which will have very bad consequences for the operator and crane equipment.

8. High-altitude suspension has not been sealed with safety rope for a long time.

Due to the requirements of installation process, some equipment or parts need to be hung in the air before being fixed in place, while some suspenders stay in the air for a long time. If there is no safety rope, once they are subjected to accidental vibration and impact, it will lead to serious consequences of the falling of the suspenders.

9. The construction is too busy to confirm the progress.

There is no underground consultation at the crane station; Before the operation, the weight of the hoisted object was not confirmed, and the hidden dangers in the surrounding environment, such as high-voltage lines, operating equipment, leakage points of coal-oxygen pipelines, safety warning signs of the owner's unit, were not found in time, causing heavy losses.

10. Use of "faulty" slings

Some people use rope buckles to save trouble, but they don't know that they are discarded by others. Some of them have suffered internal injuries, some have been burned locally, and some have been welded. These faults and problems are not easy to be found. Others covet to buy unqualified slings such as pulleys and rings produced by informal manufacturers cheaply, which makes workers very nervous at work. To ensure construction safety, please don't use the rope buckle thrown by others, and cut off the damaged and scrapped rope buckle in time to prevent others from misusing it; Don't buy suspenders made by informal manufacturers.

1 1. Use hemp rope as safety rope.

Because the load-bearing capacity of hemp rope is far less than that of wire rope, and hemp rope is easy to be damaged in daily storage and use, which reduces the tensile strength, so using hemp rope as a safety rope can not play a safety role, but makes people psychologically dependent and cause accidents.

12. No warning area is set.

Failing to set up a safety warning zone and arrange a safety guardian in time in the dangerous area of heavy lifting and aerial work, causing others to enter the dangerous area under unknown circumstances and causing accidents.

13. The "brake lever" was not properly considered when the crane lifted heavy objects with a long arm.

When the long arm of a crane is used to lift a heavy object, the vertical line between the rod head and the center of gravity of the heavy object will change due to the "braking" of the crane arm. If the lifting rod is not adjusted properly, the lifted weight will shift instantly. If the operator is thoughtless and fails to take evasive measures (especially in the air), an accident may occur.

14. When two cars are lifted and overturned together, it is not allowed to weigh an item.

Because the center of gravity changes when capsizing, if the calculation is not accurate, it will easily lead to overload and instability of a crane, which will not only threaten the safety of people, but also cause huge mechanical and economic losses. This has profound lessons in history and needs special attention from construction and technical personnel.

15. Insufficient consideration of climate impact

When hoisting large pieces in windy days, the influencing factors of wind load on cranes must be considered. Do not operate when there is danger or the wind force exceeds the safety regulations.

To sum up, the hoisting operation involves construction organization, operation design, scheme formulation, machine selection, personnel operation skills, construction experience, cooperation and mutual protection, multi-job cooperation, environmental characteristics and climate factors. Therefore, in order to do a good job in hoisting, we should attach great importance to all aspects from construction management to personnel operation, and act in strict accordance with science.

Crane hoisting operators should not only strictly implement relevant regulations, but also learn operating skills, sum up experiences and lessons in time, and improve their ability to prevent accidents. In specific operations, they should also pay attention to the fact that everyone's construction experience, operating skills and knowledge are different, and their judgments on dangers and hidden dangers in hoisting operations are also different, so it is particularly important to cooperate and protect each other in hoisting operations. At ordinary times, we should also vigorously advocate talking more, reaching out more and making more suggestions. At a critical moment, a word and a suggestion from the leader can often avoid accidents in time.
