"Three Good", "Four Meetings" and "Five Discipline" of Tower crane Suspension Operation
In the course of operation, the tower crane operator must strictly follow the equipment safety operation rules, and manage the equipment that belongs to his own operation, and carefully maintain the tower crane used by him, so that the tower crane is often in a neat, clean, lubricated, and safe state. We will earnestly implement the "three good", "four meetings" and "five disciplines."
1, "three good" that is, good management, good use, good health
Good management: the tower is responsible for the maintenance of the tower, not to allow others to move their own equipment, the equipment's safety protection device, spare parts should be maintained intact.
Good use: Strict implementation of operating procedures, rational use of equipment, stick to the job.
Maintenance: Strict implementation of the succession system, inspection, lubrication, trial operation before the class, cleaning and wiping after the class, serious regular maintenance, active participation in minor repairs, continuous improvement of the ability to repair equipment, on the basis of finding out the condition of the equipment. Gradually master the equipment's natural accident site and emergency measures.
2, "four meetings" will be used, will maintain, will check, will troubleshoot
Will use: in the rental, concentrate on the operation of the procedures, in practice constantly grope and accumulate experience, fully develop the potential of equipment, and prevent personal and equipment accidents.
Will maintain: Be careful to do regular maintenance and routine maintenance, according to the lubrication requirements of each part, to achieve fixed quality, quantity, timing, fixed point refueling lubrication.
It will inspect: perform pre-shift inspection and trial operation carefully, ensure the safety and reliability of various safety devices, braking devices, controllers, etc., and report problems in a timely manner. During the operation, the operation of the equipment is carefully observed and judged from the sound. If there is an anomaly, it should be stopped for inspection and the maintenance personnel should find out the reason.
Will troubleshoot: the tower crane general mechanical and electrical fault should be self-removal, the larger failure contract maintenance personnel jointly. In case of personnel and equipment accidents, keep the scene and report immediately to the leader.
3. "Five Principles"
& lt; 1 & GT; , certificate use equipment, comply with operating procedures
& lt; 2 & GT; Keep the equipment clean and refueling according to regulations
& lt; 3 & GT; , comply with the equipment transfer system
& lt; 4 & GT; , control tools, accessories, not to lose
& lt; 5 & GT; If you find anything unusual, stop immediately
Power outage, emergency treatment and rescue plan during crane crane operation
[ Key words: Tower power outage release date: 2012-05-03 14:54:18]
During the operation of tower crane, what should I do when I encounter a power outage? How to carry out rescue work quickly and effectively to minimize the risk of mechanical injury. In order to ensure the tower crane operation process after a prolonged power outage, special emergency treatment and rescue plans.
Organization
The project department set up an emergency rescue command team to be responsible for command and coordination.
Duties
1, responsible for the field command, understand the tower lifting height, arm position, organization of rescue work on the scene.
2, responsible for site protection, set up a cordon, maintain order, evacuate personnel.
3, responsible for notifying the equipment A organization rescue, call rescue personnel, timely safety to eliminate dangerous situations.
III. Emergency rescue procedures
When the tower crane is in normal operation, it suddenly fails to stop(for a long time), so that the lifting object is suspended in the air. For a long period of time, the following urgent measures should be taken:
1, all controllers should be dialed to "0" bit, the total power supply is disconnected.
2, professional maintenance personnel intermittently open the hoist hoist brake or open the brake handle, so that the hoisting objects fall, each time the short distance of the fall, the speed of decline must not exceed the rated speed, and finally the hoisting objects to the ground.
3, if there are obstacles and houses under the suspension. The following measures should be taken:
(1) According to Article 2, the suspension is first lowered to a safe distance from the object or the house, and then the same rotating device is braking or pulling the wind rope to prevent it from rotating under the influence of wind; A. Rotating the tower boom to an open area or to a safe part of the building, or temporarily shelving and monitoring a steel platform capable of carrying the tonnage of the hanging object, braking the same turn, setting a cordon, and then operating in accordance with Article 2;
(2) Set up a warning area under the hanging object and have special supervision to prevent personnel from walking or working under the hanging object
(3) Under the suspension is the office area, the office personnel under the suspension must temporarily leave and take measures in accordance with Section(2);
(4) If the residence is under the suspended object, the resident in the house under the suspended object shall be persuaded and guided by the project department to take temporary evacuation measures;
(5) After the power supply is restored, a full inspection is conducted and the hanging material is then transferred to the designated location for descent.
4, immediately organize safety self-inspection and self-correction, eliminate hidden dangers, ensure construction safety; The city is to organize safety education for all construction workers, improve safety awareness, observe discipline, and prevent similar accidents.
In the process of emergency rescue, a fall accident occurs at a height, and emergency treatment and rescue plans for a fall accident at a height are immediately implemented.
