General safety operation rules for crane drivers?

General safety operation requirements for crane drivers

One, the relevant personnel should carefully shift, carefully check the reliability of hook, wire rope, brake and safety protection device, and report any abnormal situation in time.

Second, before starting the machine, you should confirm that the following conditions are in a safe state before starting the machine:

(1) Whether all controllers are set to zero; (2) Whether there are irrelevant personnel on the crane and in the operation area, and whether the operators are evacuated to a safe area; (3) Whether there are uncleared obstacles within the crane operation scope; (4) Whether the minimum distance between the crane and other equipment or fixed buildings is above 0.5m; (5) Whether the power circuit breaker is locked or has warning signs; (6) Whether the truck crane level off the site as required, and whether the legs are firmly and reliably placed.

Third, before driving, be sure to ring the bell or give a warning; When approaching an operating person, an intermittent bell or warning should be given.

Four, in the normal operation process, the driver shall not engage in the following acts:

(1) Parking with authority limiter; (2) reverse braking; (3) Inspection and maintenance during lifting operation; (4) Brake with load adjustment hoisting and luffing mechanism, or increase working range with load; (5) The lifting object shall not go over the head of the person, and the person shall not stand under the lifting object and the boom.

Fifth, strictly obey the command signal. No matter who sends the emergency stop signal, it must be executed immediately.

Six, when the lifting load is close to or reaches the rated value, or when lifting dangerous goods (liquid metal, harmful substances, flammable and explosive substances), carefully check the brake before lifting, try to lift with a small height and a short stroke, and then lift it after confirming that there is no problem.

Seventh, the minimum distance between all parts of the crane, lifting load and auxiliary equipment and transmission lines should meet the safety requirements; Eighth, drivers should not operate under the following circumstances:

(1) crane structure or parts (such as hook, wire rope, brake, safety protection device, etc. ) there are defects and damages that affect the safety work; (2) The hoisted object is overloaded or may be overloaded, the weight of the hoisted object is unclear, it is buried or frozen underground, and it is squeezed by other objects. It is not allowed to stay and hang during operation; (3) The hanging object is not firmly bound, or the hanging is unstable, and there is no liner between the edges and corners of the heavy object and the sling; There are people or floating objects on the hanger; (4) The work site is dark, and the site, hanging objects or command signals cannot be seen clearly.

Ninth, when power is suddenly cut off during work, all controllers should be set to zero and the main power supply should be turned off. Before returning to work, check whether the crane works normally, and the crane can work normally only after it is confirmed to be safe.

Tenth, if there are two sets of hoisting mechanisms, it is not allowed to use the main hook and the auxiliary hook to work at the same time (the design allows the special crane to go out).

Eleventh two or more cranes lifting the same weight, each crane shall not be overloaded. During transportation, the wire rope should be kept vertical and the operation should be synchronized. When lifting, the relevant responsible technicians and safety technicians should be present for guidance.

Twelfth, open-air operation of rail crane in the wind is greater than 6 should stop operation; After the work is completed, the crane should be anchored. General safety operation requirements for crane drivers
