Safe operation procedures for heavy industries.

1. The heavy industry should be trained in professional safety, and the operator can participate in the lifting operation.

2. The safety helmet must be worn before work, and all kinds of equipment, tools and rigging are strictly inspected. No overload. Hemp rope shall not be used for mechanical transmission.

3. The on-site power equipment shall be grounded reliably and well insulated, and the mobile lamps shall use the safe voltage.

4. Multiple operations should be conducted by a special person in charge of command, unified signal and clear communication. To work strictly according to command or signal. If the operator can't see the command gesture clearly, he should set up a transit assistant to transmit the signal accurately.

5. The hoisting work should be checked first before the binding is firm. The rope should be lined with the sharp corners, and then try to lift off from the ground zero. 5 meters, can be hoisted after checking and confirmation.

6. Use the hoisting pole position to be correct, the back cover should be reliable, when necessary, the cable wind rope should be tightened, and no twisting, bending, sinking or slanting will occur after the force is stressed.

7. The winder must obey the command, see the signal and operate correctly. Strictly follow: the signal is unknown, the wire rope run off, overload, brake not to drive. When drawing with a winch, no operation is allowed in the middle.

8. When using jacks, the base should be firm, stable and correct to choose the key and balance point of the hoisting object; Between the cover and the weight should be wooden block or anti-slip mat; Slow top lift, with the top of the pad, multiple top lift, should be consistent. When using the claw jack, do not operate in front, in case the jacks slide down to cause damage.

9. No less than two cables shall be used, and the fixed position shall be secure, and shall not be tied to the poles, electromechanical equipment and pipe supports. After the cable wind rope tension should be less than 45 ° Angle with the ground. In case of need to be fixed on site building components, the relevant department shall agree. 10. When moving the high center of gravity, the ground must be flat, the sleeper pad should be hard, the tank wheel and the object should be cushioned, and the key point and balance point should be selected accurately. Follow the movement with a magnet when necessary. People need to be on high alert.

11. Warning lines should be set around lifting areas, and non-staff members are strictly prohibited. In the case of gale force above 6 level, it is strictly prohibited to carry out lifting and hoisting.

12. Do not leave the post until the lifting object is in place. The work should not be interrupted when the rigging or suspension is suspended.

13. When hanging objects are suspended, it is forbidden to stay or pass under the lifting or hanging arm, and no one is allowed to stand in front of the hoisting machine, before the pulley and the rope.

14, high operation or use other electrical and mechanical equipment, wear a seat belt and abide by relevant safety operation rules rigger should by professional training, and passed the examination held "special type of work operation card", can be engaged in lifting operations.
