The crane shall be operated by a full -time driver to obtain a special operation permit for a special operation operation permit and passed the safety environment management department to obtain a special driver.Therefore, at the work site, it is particularly important to obey the safety operation process of a heavy machine.Here are the safety operation processes of the crane and the safety technical requirements of the crane.
The general requirements for crane operators
A. The command signal should be clear and complied with the regulations;
B. When hanging, the angle between the hanging rope should be less than 120 degrees, so as not to be excessive power;
C. The corners of the rope and chain should be added with a cushion;
D. When the command object is flipped, the center of gravity should be changed steadily, and moves should not be produced outside the command intention;
E. When entering the suspension heavy object, contact the driver and set up a straight support device;
F. When multiple people are tied, one person shall be responsible for command.
4. Safety inspection and apricot cycle requirements
(1) The following situation respond to the crane and pass the inspection of the relevant standards:
A. The crane for normal work is performed once every two years;
B. After the large repair, new installation and transformation of the crane, before delivery;
C. The crane that exceeds one year for more than one year, before re -use;
D. After storms, earthquakes, and major accidents, the cranes that are damaged by the stability, stiffness, component stability and the importance of the mechanism may be damaged.
(2) When the work is heavy and the environment is harsh, the regular inspection cycle must not be less than once a month, and the regular inspection cycle shall not be less than once a year.
Crane Safety Technical Requirements
(1) When the driver operates, we should comply with the following requirements:
A. Do not use the limit -limited direct restrictions to park;
B. Do not adjust the rising and variable mechanism brakes without loading;
C. When hanging, it is not allowed to pass from the people, and there must be no one under the boom;
D. Do not check and repair when working with a crane;
E. When the hunging object is close to or reaches the rated lifting capacity, check the brakes before the lifting, and then hang it smoothly with a small height and short itinerary;
F. There is no crane to the limited limited limited limited limited position. When the hook is at the minimum working position, the wire rope on the rolling tube must maintain the designated safety circle;
G. When working on a crane, the minimum distance from the arm frame, patching auxiliary tools, steel wire ropes, cable wind ropes and heavy objects should not be less than the regulations of Table II;
H, a liquid crane, should be parked and stopped at the airport field in accordance with the requirements of the instructions, and the legs are firmly and reliable;
I. Weighing machine -free braking performance. Except for special emergencies, it is not allowed to use anti -vehicle to brake.
(2) At the moment of one of the following situations, the driver should not operate:
A, overloaded or unclear weights, such as hanging straight objects with weight or unclear tension, and cable -stringing slice;
B. Structural or components have defects or injuries that affect safety work, such as the brake safety installation of straight failure, the hook nut anti -loose damage, the wire rope damage to the scrap standard, etc.
C. The bundle and hanging hanging or unbalanced may slide, and there are no cushions between the edges and corners of the heavy object and the wire rope.
D. Someone or floating objects on the hanging object;
E. The work venue is dim, and the venue, the situation of the hanging object, and the command signal cannot be seen clearly.
(3) When the same heavy objects are lifted with two or more cranes, the wire rope should be maintained vertically, and the lifting and operation of each crane crane should maintain the loads that the carrons that are synchronized with each other.If the above requirements are not met, the rated lifting capacity should be reduced to 80%; the chief engineer can also reduce the rated lifting capacity according to the actual situation.During the lifting, the chief engineer should be guiding.
(4) The cranes of the main and deputy set up lift mechanisms should not be started at the same time. Except for the design that allows the design to be used at the same time.
The general requirements for the safety operation of the crane
A. When the driver takes over, it should be checked to deal with brakes, hanging Jun, wire rope and safety devices. When the performance is abnormal, it should be excluded before operation;
B. Before driving, you must be a bell or alarm. When the operation is close to others, you should also give a disconnected bell or alarm;
C. The operation should be performed in accordance with the command signal, and the emergency parking signal should be executed immediately;
D. When no one is confirmed on the heavy machine or around it, you can close the main power supply. If the power supply disconnect device is locked or there is a sign, the relevant personnel should be removed before the main power supply can be closed;
E. Before closing the main power, all the handle of the pullers should be placed at zero;
F. When the power is disconnected at work suddenly, all the controller handle should be pulled back to zero. Before working again, check whether the starting heavy machine action is normal;
G. The cranes of open -air assignments on the orbit should anchor the crane when the work is over.When wind power is greater than level 6, work should generally stop working and anchor the crane.For the cranes such as the gatekeeper, etc., when the wind power is greater than the 7th level, the work should be stopped and the crane is anchored;
H. When the driver is maintained, the main power should be cut off and the alarm sign or lock is hung. If there is a failure to be eliminated, the successor of the successor should be notified.
