How many levels of wind are prohibited from hoisting operations Tower cranes can not operate above h

Lifting operations are prohibited above level 5 wind.

It is forbidden to operate the crane when the wind speed exceeds the conditions specified by the equipment manufacturer. If the manufacturer does not stipulate, it is forbidden to hoist the wind above level 5.

The standard requires that high-altitude operations should be stopped in windy weather above level 5.

Bad weather such as rain and snow.

When working at height, there should be reliable anti-skid and cold-proof measures; If there is a strong wind above level 5 (inclusive), the lifting and hoisting operation of the large formwork should be stopped; The tower crane must be stopped in strong wind weather above level 6.

The hoisting operation shall not be dismantled in the event of rain, snow, fog and wind greater than level 4.

Safety specifications for hoisting operations.

1. Designate personnel engaged in command and operation.

2. Conduct safety inspection and confirmation of the lifting spreader to ensure that it is in good condition, such as: whether the hook safety buckle is effective, whether the wire rope is broken and stranded, and whether the U-ring is tripped.

3. Confirm the implementation of safety measures and the hoisting environment.

4. Check the safety status of the hoisting area, including the demarcation, identification, obstacles, warning area, etc. of the hoisting area.

5. Wear personal protective equipment correctly; **In the event of a possible accident, take effective precautions and choose a safe escape route.

The above content referenceEncyclopedia - Hoisting.

It is forbidden to operate the crane when the wind speed exceeds the conditions specified by the equipment manufacturer. If the manufacturer does not stipulate, it is forbidden to hoist the wind above level 5.

Lifting operations are prohibited above level 5 wind.

Category 5 wind or above.

Tower cranes are not allowed to be constructed above level 6 winds.

According to the unified regulations of the tower crane tower base standard specification, when the wind exceeds level 4, the tower crane can work, but if the tower crane is in a non-working state, it should be parked downwind to ensure that the tower crane balance arm is not affected by the wind; When the wind force exceeds level 6, the tower crane should be stopped to avoid accidents in the balance arm.

Tower crane insistence"Ten"Do not hang. After the operation is completed, the power should be cut off and the box should be locked, and the machinery should be done"Cross"Assignment work. The contents of the ten non-hanging are as follows:

1) Diagonal hanging is not hoisting.

2) Do not hang when overloaded.

3) If the bulk is too full or the bundle is not firm, it will not be hung.

4) The edge of the hanging object is not hung without protective measures.

5), the person standing on the hanging object does not hang.

Lu Jutong 6), the command signal is not clear.

7) The components buried in the ground are not hoisted.

8) If the safety device fails, it will not be hoisted.

9) The light is dark and you can't see clearly.

10) No hanging in strong winds above level 6.

Strong winds above level 6 are not allowed to work, including level 6.

The contactor power supply in the tower crane distribution box is loose, the terminal board wiring bolt is in poor contact, and the main contact of the contactor is poor; Poor ablation contact of the wiring bolt of the motor rotor and stator coil; The wear of brake pads of high-speed and low-speed motors exceeds the specified requirements; The gears of the gearbox are broken and the bolts of the fixing gears are loose; The phase loss protector does not work.

The pitching luffing boom tower crane is not realized by the lifting arm of the crane boom, and its advantages are: it can give full play to the effective height of the boom, the mechanism is simple, and the disadvantage is that the minimum amplitude is limited to about 30% of the maximum amplitude, can not be completely close to the tower body, and the load is lifted together with the boom when luffing, and can not be luffed with load.

In terms of safety regulations, strong winds above level 6 are not allowed to operate, including level 6. However, most project departments will not think too much for you, depending on their own grasp.

You can't hurt others, and you can't hurt yourself. There is really no way to communicate with the project department, and the project manager knows the stakes.

Good luck with your work and stay safe.
