( 4 ) Conduct safety inspection once a week and report once a month. Strict bonus and punishment.

( 5 ) Strengthen safety inspections, hold safety meetings in a timely manner, and actively carry out safety education and safety activities.

4 , lifting and lifting

1 ) General

Before carrying out the lifting work, the technicians calculate the weight of the load and formulate the lifting plan according to the crane performance and environmental conditions, and provide the solution to the driver including the lifting worker, the cable operator, and the crane driver. The driver checks the load weight and effect by observing the load table during the operation. Torque.

2 ) Use of wire rope

(1) Reasonable safety factor for wire rope selection;

(2) When the hoisting rope is evenly loaded, the steel wire of the plug-in joint should not pass through the reel or pulley block;

(3) It is strictly forbidden to stay or walk in the vicinity of the force ropes. The guardian shall be set up to supervise the use of the open-door pulley to lock the hook-and-loop to prevent the wire rope from coming out;

(4) If the surface of the load has an angular surface, effective protective measures shall be taken when the sling is in place;

(5) The slings are tied above the center of gravity of the heavy objects, and they are tied together symmetrically to prevent them from being biased or slipped. If it must be bundled below the center of gravity due to special circumstances, effective protective measures shall be taken and approved by the technical person in charge of the unit;

(6) In the process of use, steel wire ropes are frequently inspected for broken wires, kinks, bends, flattening, wear, corrosion, or arcing. The inspection cycle and scrap standards are in accordance with the National Inspection and Disposal of Wire Rope for Cranes. Specifications (GB5972-86 ).

3 ) Pulleys and Pulleys

(2) The surface of wheel grooves of the pulley block is smooth, and check for defects such as cracks, bumps, etc., and the important parts thereof are subjected to nondestructive testing periodically;

(3) All rotating parts of the trolley must be run flexibly and well-lubricated. The net distance between the sliding cars on the block is generally not less than 5 times the diameter of the wheel . When two or more sets of pulley blocks bear a force, set the balance wheel. ;

(4) It is forbidden to use welding reinforcement methods to make up for the defects of hooks, rings and crane beams. When the lifting weights of the hooks are unhooked, a locking device is added to the hooks.

5 , human transport

1 ) Check loading and unloading locations and road conditions before operations, and remove obstacles;

2 ) Before the operation, conduct a thorough inspection of the used machinery and tools (such as jacks , pulley blocks, wire ropes, manual hoists, etc.), and do not use them if they are damaged;
