I. General:
1. The crane consists of: bridge, trolley equipped with lifting and operating mechanisms, trolley operating mechanism, maneuvering room, trolley conductive device, crane power supply conductive device and other components.
2. Men and women workers aged 18 years old, after a qualified physical examination, safety education and specialized training to drive the crane, qualified by the relevant departments, issued by the special types of operating certificates, can be operated independently.
3. The operator should have all the crane institutions and devices and the performance and use of all electrical equipment and general knowledge. To have all the institutions of the operation and maintenance of knowledge and practical skills, familiar with the command gestures signal.
Second, the operator's duties before work
1. Understand the previous shift handover record, enter the operator's room and then close the door of the operator's room. 2. 2. in the case of ensuring that the previous shift power outage, check to see if there are other people and debris on the crane, the slip line and collector should be intact, the controller or other superconducting starting equipment handle should be in the zero position. 3. check the movable and rotating parts of the crane mechanisms, whether the bearings and lubricating devices of all mechanisms are firm and intact, and refueling should be done if the oil is insufficient. 4. check whether the accessories such as wire ropes and hooks are intact. 5. an exact ringing signal should be given before each closing. After closing the main knife gate and before performing the lifting work, several idling runs should be made with the carriage, trolley and grab unloaded, and the correctness and reliability of the brake and end limit switch action should be carefully checked. 6. After the final inspection of the crane, the operator shall record the results of the inspection in the record book of the shift handover.
3. Duties of the operator at work
1. The operator must strictly observe the operating rules and regulations at work, and must operate the crane in accordance with the requirements of the work and the working principle of the equipment. Before each start-up must be a comprehensive inspection of the traveling car. The size of the car next to the track, mechanical side, electrical on whether someone patrol maintenance, oil oil level is normal, brakes, wire rope, safety limit is and electrical interlocks are intact, to ensure the safety of personal equipment, in the bell twice before starting.
2, should be in the prescribed safety aisle, special platform or escalator walking and up and down
3. Operators in the daily work should strictly abide by the "ten do not hang" a. Things standing on the people or floating objects do not hang; b. Overloading do not hang; c. Dark light signal can not see clearly do not hang; d. Flammable, explosive, Dangerous goods do not hang; e. equipment with disease or strong shaking load does not hang; f. Wire rope is not qualified to hang, not securely tied do not hang; g. Buried in the ground or solidified in the ground do not know the load does not hang; h. hoisting the center of gravity is too biased do not hang; i. not crooked pulling and slanting hanging, j. sharp corners, edges and corners are not padded good do not hang; k. work against the rules do not hang.
4. Operators should pay attention to lubrication, do not overheat the bearings, refueling should stop the crane mechanism and cut off the power supply.
5. In the following cases, the operator should send a warning signal: a. When the crane starts to send power; b. In the same floor or another floor close to other cranes; c. In the lowering of the load and lifting the load; d. Load in the lifting close to the staff below; e. Safe passageway for people to work or people start; f. Load in the ground is not high position of the movement; g. Hoisting the load equipment g. When the equipment on which the load is to be lifted is malfunctioning.
6. It is strictly prohibited to lift the load from above the person lifting or staying, the crane should be lifted along the safe passage, if there are people below should be issued a continuation of the signal, if the passage is blocked by a person or something else, then the operation should stop.
7. It is strictly prohibited to overload lifting, the operator does not know the tonnage of the load before, not blindly lifting. If the operator believes that the implementation of a lifting task has unsafe factors, the operator has the right to refuse to carry out, and report to the relevant leaders.
8. lifting goods, in the four ropes are tensioned before lifting the workpiece, not two rope lifting.
9. After the start of work, the first lifting load, the operator should be lifted no higher than 0.5 meters, and then put back to the ground, as a way to understand the action of the brake is intact.
10. The starting and braking of the crane mechanism should be rhythmic, and should not occur rapid jumping and impact phenomenon. It is prohibited to suddenly trigger the mechanism from forward to reverse.
11. When lifting loads in the horizontal direction, the load should be lifted 0.5 meters higher than what the ground can touch.
12. It is prohibited to lift the load crookedly and diagonally, to use the crane to pull up the things buried in the ground or condensed to the ground, and to use the crane to carry out the work with strong shaking load force.
13. When the hook is placed in the lowest position, the wire rope on both sides of the reel should be retained at least three turns each.
14. After work or rest into, the load should not stay in the air. If in the lifting, crane failure or power outage, and the weight can not be put down, immediately draw the danger zone, the load may fall off the place enclosure, and send a signal to prevent people to go under the weight. If it fails to work for an extended period of time, then try to pad or manually lower the weight. Pull the controller handle to the zero position and cut off the power supply.
15. The general operator can only use two controllers at the same time, and grasp them with two hands, only to avoid dangerous accidents in serious moments, only allow exceptions to use three handles.
16. It is forbidden to lift flammable and explosive goods. (e.g. acetylene bottles)
17 The operator may only follow the hand signals of the starter, but regardless of the stop signal given by anyone, the operator must stop immediately. The operator shall not carry out a wrong or unclear signal if it is given by the starter. Otherwise, accidents resulting therefrom shall be the responsibility of both the starter and the operator***.
18. When two cranes are used to lift the same heavy load, certain safety measures must be taken, agreed to by the safety and technical department and the production equipment department, and carried out under the direct supervision of the inspectors of these two units.
19. several cranes on the same track at the same time action, in order to prevent each other collision, crane operators should use the signal to make the cranes to maintain a distance of not less than two meters. When two cranes on the same track are close to each other, the speed of the crane should be slowed down as much as possible, and only when it is necessary to use the limiter bar and limit switch to stop automatically.
20. Whether large or small cars, should slow down when driving close to the endpoint limiters and blocks.
21. work found that the crane and its mechanism out of order, the operator should be put down the load, cut off the electric switch of the operator room, immediately report to the maintenance personnel, give the elimination, can not be accommodated to use. Operators can not disassemble and alter at will. Crane because of some reason to make the work interrupted, such a situation should be recorded in the duty handover record book.
22. If the wire rope falls from the reel, pulley, or strung up, the operator should immediately stop working and report what happened to the leader.
23. Terminal limiters or terminal switches on cranes are set to avoid dangerous accidents and are prohibited to be used for regular stopping.
24. Cranes are not allowed to start without the key limiter or the terminal limiter is out of order.
25. start the trolley, trolley controller, should be a gear gradually closed, in pull back to the zero position cut off, it should be rapid. When pulling the controller back to the zero position, should be estimated in advance to the hook, big car, trolley, the inertia, in order to enable them to stop in the appropriate position, it is prohibited to turn the handle over the zero position to brake. Exceptions are allowed only to avoid unfortunate accidents.
26. Accidents should immediately stop work, cut off the power supply, protect the scene, demarcate the danger zone, and report to the relevant departments. Not allowed to move without the approval of the head of the relevant departments.
Fourth, the operator's duties after the completion of the work
After the crane stops working, the operator should comply with the following rules:
1. The grab should be placed flat on the ground, and is not allowed to hang in the air.
2. Stop the trolley at one end of the main beam, and drive the trolley to a fixed parking place.
3. All controller handles should be placed in the zero position, turn off the emergency switch and pull open the gate switch.
4. The operator should check the condition of the crane at the end of the shift, and record the problems found during the work and inspection in the shift handover book and hand over to the successor.
