How does lifting equipment, lifting machinery work normally?

According to the general administration of quality supervision, inspection and quarantine (aqsiq), the "catalogue of special equipment" published by the national quality inspection pot [2004], the lifting platform belongs to the special equipment.

According to the structure, the lifting equipment can be divided into light and small lifting equipment, lift, crane and overhead monorail system, etc.

However, small and small lifting equipment mainly includes lifting gear, jack, manual hoist, hoist pulley, electric hoist and ordinary winch, which mainly includes construction lift, elevator and so on.

Lifting machinery can not work in the following situations:

1. The safety device fails or is not allowed to be hoisted;

2. No hoisting of strong winds above 6 or above.

3. The light in the scene is dark, and it is not clear that the hanging objects can be hoisted;

4. Loose binding or material loading is not allowed to hang;

5. The signal conductor shall not be suspended;

6. The direct contact between the edge and wire rope is not allowed to be hoisted;

7. No hanging by inclined hanging;

8. No hanging in the ground;

9. There is no hanging on the hanger;

10. The lifting weight is not clear or overloaded;

Cranes mainly include tower crane, gantry crane, semi-portal crane, bridge crane, wheel crane, port crane and so on.

In a certain range of lifting machinery is also called crane, this type belongs to the material handling category.

Therefore, when we use the above hoisting equipment, we need to enter into the seat, not overqualified.

What are the requirements for crane hoisting operation?

1, to participate in the lifting operation personnel, including the driver, rigger, signalling, welders, etc all should belong to special operations personnel, must be tested and approved by the professional training, acquire the certificate of approval, and confirmed by the physical examination for high homework personnel;

2, lifting machinery into the site shall be inspected after acceptance, reassemble the hoisting machinery shall be carried out in accordance with the provisions, test run, including the static load and dynamic load test, and the various security device reliability sensitivity test.

After assembly, the derrick should be inspected by the test crane and confirmed to be in conformity with the requirements.

3, lifting operations shall be the field in detail before, according to the engineering characteristics and preparation of special construction scheme, the working environment and the enterprise technology, head of the examination and approval, its content should include: the scene environment and measures, engineering general situation and construction technology, and selection of hoisting machinery basis, design and calculation of the crane boom, anchor design, selection of the design of the steel wire rope and rigging and endurance and the requirements of the road, the component storage in place diagram and loading process in various protective measures, etc.;
