This standard adopts the following definitions:
Lifting operation
The working process of lifting heavy objects with various machines and tools and changing their positions.
4 Classification and grading of lifting operations
4. 1 Classification of lifting operations
According to the weight of lifting heavy objects, lifting operation is divided into three grades:
When the lifting weight is more than 80 tons, it is a first-class lifting operation;
When the weight of lifting heavy objects is more than or equal to 40 tons and less than or equal to 80 tons, it is a secondary lifting operation;
When the lifting weight is less than 40 tons, it is a three-level lifting operation.
4.2 Classification of lifting operations
According to the hoisting operation level, hoisting operation is divided into three categories:
The first-class hoisting operation is a large-scale hoisting operation;
The secondary hoisting operation is medium-sized hoisting operation;
The third-level hoisting operation is a general hoisting operation.
5 Safety requirements for lifting operation
5. 1 Lifting operators must hold a special type of work permit. Lifting objects with a weight greater than 10 ton shall obtain a lifting safety operation certificate. See the appendix for the format of lifting safety operation certificate.
5.2 The hoisting construction scheme shall be prepared for hoisting objects and civil main structures with a weight greater than or equal to 40 tons. Although the weight of the hoisting object is less than 40 tons, the hoisting construction scheme should be prepared under the conditions of complex shape, small stiffness, large length-diameter ratio, precision and rigor and special construction. The hoisting construction plan can be implemented only after it is reviewed by the competent construction department and the safety technology department and approved by the competent factory director or chief engineer.
5.3 Before all kinds of hoisting operations, safety warning signs should be set at the hoisting site in advance, and special personnel should be assigned for supervision, and non-construction personnel are not allowed to enter.
5.4 During hoisting operation, there should be sufficient lighting at night. When outdoor operations encounter heavy snow, heavy rain, fog and strong winds of magnitude 6 or above, operations should be stopped.
5.5 The lifting operators must wear safety helmets, which shall comply with the provisions of GB 28 1 1, and the work at heights shall comply with the provisions of HG 230 14.
5.6 Before lifting operation, check the lifting equipment, wire rope, wind rope, chain, hook and other machines and tools to ensure safety and reliability, and do not use them in spite of illness.
5.7 During hoisting operation, it is necessary to have a clear division of labor, stick to their posts and conduct unified command according to the contact signals specified in GB 5082.
5.8 Pipes, pipe racks, poles, mechanical and electrical equipment, etc. are strictly prohibited. As a hoisting anchor point. Without the examination and accounting of the motor and construction departments, buildings and structures shall not be used as anchor points.
5.9 Before lifting operation, the operating parts, safety devices, slings and rigging of various lifting machinery must be inspected in detail, and the safety devices of lifting equipment should be sensitive and reliable. Before hoisting, the crane must be tested and the operation can be carried out only after it is confirmed.
5. 10 No one is allowed to lift heavy objects or lifting machinery. Under special circumstances, reliable safety measures should be taken and approved by the on-site commander if it is necessary to ascend and descend with it.
5. 1 1 If it is necessary to carry out hot work at the hoisting operation site, the provisions of HG 230 1 1 shall be observed. Hoisting operation site ......
The lifting operation is divided into several levels to fill in the blanks.
Classification of hoisting operation: hoisting operation is divided into three grades according to the quality of hoisting heavy objects.
(1) the mass of the lifting objects in one lifting operation: > > 100t.
(2) The weight of lifting heavy objects in secondary lifting operation: 40t≤ to ≤ 100t.
(3) The quality of lifting heavy objects in the three-stage lifting operation: < < 40t.
What are the cranes commonly used in hoisting operations?
Lifting belt, wire rope rigging and crowbar.
Commonly used steel wire ropes include phosphating coated steel wire rope, galvanized steel wire rope, stainless steel wire rope or plastic coated steel wire rope, which are used in atmospheric environment. Manganese phosphating coated steel wire rope produced by patented technology has the longest service life, and hot dip galvanized-phosphating double coated steel wire rope is preferred in heavy corrosive environment. Phosphating coating improves the wear resistance and corrosion resistance of steel wire rope, which is the reason for improving the service life of steel wire rope. Smooth wire ropes are being completely eliminated.
What are the rules of lifting operation?
On-site supervision of security personnel, construction personnel make plans in advance, and then implement the "Ten Don't Hoist".
What are the three certificates for lifting operation?
You are talking about "one machine and three certificates" for crane operation. When using a truck crane for hoisting operation, it is necessary to check the "three certificates for one crane", in which the "three certificates" are the crane inspection certificate (1) and the crane operator certificate (3) the hoisting operator completion certificate.
Be clear about what to wear when you mention it.
Check the settlement and hoisting preparation of crane trolley, wire rope and supporting ground.
