Lifting safety technical measures

1. Style statement

during the lifting of air water source well pipeline and water pump, this Enron technical method is specially formulated for the assurance staff to ensure that the project is completed and accepted on schedule

2. This mainly refers to the supply instruments and other general instruments. According to the

crane safety regulations

coal mine safety regulations

coal mine safety management system

project overview

in order to ensure the normal water supply of the water source well, it is necessary to hoist the water pump of the water source well, and our team is responsible for hoisting the water pump of the water source well according to the placement of the mine

pump model:

pump motor power:

pipeline model: dn89, a total of 260 meters

4. Construction preparation

technical preparation

learn technical data and lifting safety regulations, strictly follow the requirements of the regulations, and stop checking homework

before lifting, all staff involved in the construction must be familiar with the lifting method and project content, stop the construction according to the scheme requirements, and strictly perform the procedures and standards

machinery, east-west preparation

often use East-West electric welding machines, hoisting ropes, oxygen acetylene, crowbars, hammers, box wrenches, open-end wrenches, bolt loosening agents, etc

construction procedure

Enron method and preparation task before lifting → crane in place → device lifting things → lifting → differentiation of pipelines, the cultural exchange between China and Mongolia is becoming deeper and wider → assembly of motors → replacement of motors → assembly → test run

5. Enron technical method

during the lifting process, there should be the same instruction signal, and all staff involved in the construction must be familiar with this signal, so that all operation posts can coordinate measures. All construction staff should concentrate, and it is strictly forbidden to talk, laugh and make trouble, so as to ensure safety in the construction process

all staff involved in the construction are not allowed to drink alcohol before the task. They must be really familiar with the on-site homework environment. Everyone should choose the hiding space or route in an unsafe environment according to their respective division of labor

3. When lifting, a leader or team leader should give instructions on the spot and assign a special person to watch the shift. When lifting, the operating staff should stay away from the lifting point and other staff should hide in the Enron address; In case of any unsafe hidden danger, stop the task immediately, stop the treatment, and do not stop the installation task if the treatment is incomplete. 4. During the construction process, the construction staff must divide the work in detail and understand their responsibilities. In the whole hoisting process, it is necessary to follow the on-site order and follow the orders. Its excellent toughness helps to ensure that the ribbed parts of the water inlet (outlet) fasteners of the polimotor 2 can maintain a reliable seal without cracking

5. When lifting, all the sites are assigned by the general instructions and instructions. The sub instructions of each post box should accurately perform the orders of the general instructions, so that the notification signal is agile and accurate, and should be within the scope of their own responsibilities

6. In the whole construction process, the site should be cleaned up, and the root obstructions should be cut to facilitate the operation

7. Construction staff must wear safety helmets

8. Before hoisting construction, it is necessary to taste and observe the climatic environment in time. Generally, it is not allowed to work in rainy and snowy days, in the open air or at night. If it must be stopped, there must be anti-skid and full lighting methods. At the same time, with the approval of the leader, it is strictly prohibited to hoist when the wind force is greater than level 6, and large-scale equipment cannot be hoisted when the wind force is greater than level 5

9. Before hoisting, relevant parts should be organized to jointly stop comprehensive inspection according to the requirements of the construction plan. The inspection contents are:

(1) whether the construction of construction machines and riggings is different from the plan

, whether the construction site is suitable for the operation requirements

, whether the equipment to be hoisted is suitable for the hoisting requirements

Whether the construction electricity can be guaranteed or not, the process can be restarted by adding another batch of fuel (5). Understand the division of labor and instructions of staff; After checking and confirming that it is correct, the lifting order can be issued. After entering the operation post, the construction staff must still stop checking the post. After checking and confirming that it is correct, they can stand by for operation. If it is necessary to lift the next day, they should organize staff to stop site security

10. Before lifting, the seniors should carry out trial lifting and check the stress environment of each part. Continuous lifting can be carried out only when the environment is normal

11. During the lifting process, without the permission of the on-site instruction staff, it is not allowed to stay under the lifting weight and around the stressed rigging

12. No one is allowed to accompany the lifting objects to take off and land in the ordinary environment. If it is necessary to accompany them in the special environment, the feasible safety method should be adopted and approved by the leader.

13. The hoisting construction site should have a special area to send personnel for warning. Non construction staff of the project are strictly prohibited to enter. Construction instructions and operating staff should wear identification signs, and those without identification signs are not allowed to enter

14. In the process of hoisting, if it is interrupted for some reason, measures must be taken to stop handling, and heavy objects must not be suspended overnight

6. Safe lifting scheme of crane

1. When hanging the sling, confirm the position of the sling according to the center of gravity of the object; When lifting with two fulcrums or cross, the jack rope, snap ring, lifting wire rope, etc. at the hook shall be in accordance with the safety regulations of the lifting operation

2. The hanger should be firmly hung, and the hook should be sealed to prevent the steel wire rope from slipping during lifting; When binding objects with edges and corners or sharp edges, the contact between the steel wire rope and the object shall be padded with gunny bags, rubber, etc; When lifting long and large objects, slip ropes should be tied

3. When lifting objects, first lift the objects 10 ~ 20cm away from the air. After checking and confirming that there is no abnormal scene, the objects can be promoted continuously

4. When placing the object, it should be lowered slowly, and the hook can be loosened only after confirming that the object is placed safely and firmly, so as to prevent the object from tilting and overturning and hurting people

5. When lifting objects, homework staff shall not stay around the stressed rigging, especially inside the stressed rigging

6. During the lifting class, the driver should obey the instructions of the signalman to prevent other staff from talking to the driver or giving instructions casually. If the lifting is found to be defective, it must be handled by the signalman, except in an emergency environment

7. When lifting objects, it is strictly forbidden to stand in the area touched by the reverse rotation of the boom and under the weight. It is not allowed to get close to the hoisted objects and stretch the head under the hoisted objects to observe the environment. It is also forbidden to stand on the hoisted objects

8. When using a crane with large and small hooks, the large and small hooks shall not lift objects at the same time
