How far should the tower crane be from the building?

According to the actual situation, it is decided that from meters to 20 meters, the best distance is 4-5 meters, and it is necessary to consider whether it can be lowered when dismantling the tower.

It should also be determined according to the instructions of the tower crane attached to the wall. Generally, it is 8 meters, and if it is longer, it will be attached to the wall with non-standard.

Generally, the center line of the tower crane shall not be less than the outer edge of the building, the maximum is the arm length of the tower crane minus the longest distance of the building at the location to be installed, for example, the tower crane is 50 arm length, and the distance between the wall edge point at the point of the wall and the two corners of the building at the far end of the point is 30m and 28m respectively, then the maximum distance is 50-30 = 20m. The "cantilever height" of various types of tower cranes is slightly different, and generally shall not exceed 24m.

According to the provisions of the "Tower Crane Safety Regulations": the safety distance between the tail of the tower crane and the surrounding buildings and their peripheral construction facilities is not less than.

The minimum erection distance between the two tower cranes should ensure that there is at least a distance of 2m between the end of the crane arm of the low-level tower crane and the tower body of another tower crane; The vertical distance between the parts in the lowest position of the high tower crane (the hook rises to the highest point or the lowest part of the counterweight) and the parts in the highest position in the low tower crane should not be less than 2m. The latest specification is that the distance between the tower crane and the proposed building is 4m.

Tower crane: tower crane is the most commonly used lifting equipment on construction sites, also known as "tower crane", with a section of the length (height) (referred to as "standard section"), used to lift construction steel, wooden flute, concrete, steel pipe and other construction raw materials. Tower crane is an indispensable piece of equipment on the construction site.

The top of the self-elevating tower has truncated cone type, forward or backward truncated cone type, herringbone frame type and diagonal brace frame type. All the upper rotary tower crane needs to be set with a counterweight, and its function is to support the counterweight, which is used to constitute the balance moment that is opposite to the direction of the lifting moment in terms of action required by the design. In addition to the counterweight, a lifting mechanism is often installed at its tail.

Summary. The safety distance of adjacent tower cranes means that it should be guaranteed to be not less than 2m in both horizontal and vertical directions.

In order to ensure the safety of construction, the tower body and the crane arm of the adjacent tower crane can not interfere, and try to ensure that the tower crane can rotate freely when the wind is too strong; The safety distance between the rear arm of the tower crane and the adjacent building is not less than 50cm; The safety distance between the tower crane and the power transmission line meets the requirements.

If it is found that the safety distance between the tower crane and the transmission line does not meet the regulations, the solution: that is, to set up a protective frame, the erection of the protective frame in principle to be erected by power failure, and no metal materials shall be used.

Hope mine is helpful to you.

What is the safe distance between the two tower cranes?

Hello, glad to answer for you. The safety distance of adjacent tower cranes means that it should be guaranteed to be not less than 2m in both horizontal and vertical directions. In order to ensure the safety of the source sale, the tower body and the crane arm of the adjacent tower crane can not interfere, and try to ensure that the tower crane can rotate freely when the wind is too strong; The full distance between the rear arm of the tower crane and the adjacent building is not less than 50cm; The safety distance between the tower crane and the power transmission line meets the requirements.

If it is found that the safety distance between the tower crane hail and the transmission line does not meet the regulations, the solution: that is, to set up a protective frame, the protective frame should be erected in principle without power failure, and metal materials shall not be used. Hope mine is helpful to you.

It is the distance between the tower crane and the adjacent street.

We are the workspace.

I'm the inspection line.

The highest point of the boom of the tower crane is 6m away from the minimum distance of the high-voltage line.

The safety distance of the high-voltage line below 1kV is 4 meters; The safety distance of 1-10kv high-voltage line is 6 meters; The safety distance of 35-110kv high-voltage line is 8 meters; The safety distance of the 154-220kv high-voltage line in Mengzhou is 10 meters; The safety distance along the 350-500kv high line is 15 meters.

The fixing screws of the power supply inlet and outlet of the contactor in the distribution box of the tower crane are loose, the terminal board and the wiring bolt are in poor contact, and the main contact of the contactor is poor. The wiring bolts of the motor rotor and stator coil are poorly ablated. The wear of brake pads of high-speed and low-speed motors exceeds the specified requirements.

The gearbox gears are broken and the fixing gear bolts are loose. The phase loss protector is constantly wide and functional.

Summary. The horizontal safety distance is the minimum tower arm length plus 3 meters; The height difference is based on the fact that the structures cannot collide with each other, and it is generally possible to stagger by 5-8 meters.

The horizontal safety distance is the minimum tower arm length plus 3 meters; The height difference is based on the fact that the structures cannot collide with each other, and it is generally possible to stagger by 5-8 meters.

The safety distance of the tower crane should be guaranteed in both horizontal and vertical directions not less than 2m of safety distance, and the tower body of the adjacent tower crane and the accompanying arm of the lifter can not interfere, so as to ensure that the tower crane can rotate freely when the wind is too strong. The safety distance between the rear arm of the tower crane and the adjacent building is not less than 50cm; The safety distance between the tower crane and the transmission line meets the requirements.

Hello. This tower crane is as high as the height of the safety no.

It's certainly not safe to be as tall as the height, dear.

The booms of the two tower cranes are to be staggered. Kiss.

The installation of the tower crane said safe.

This is an illegal operation, find the project leader to deal with it, dear.

You can send me the height of this tower crane safely.

There's no such thing as a document to happen, dear.

The lifting height of the tower crane includes two parameters, one is the lifting height when the tower crane is installed at the free height, and the second is the maximum lifting height when the tower crane is attached, the tower crane does not need to be attached when the free height is installed, and the tower crane can reach 40 meters, which can meet the needs of small high-rise buildings. In order to prevent the tower crane hook from lifting too high and damage the equipment and safety accidents, each tower crane is installed with a tower crane height limit reeder only device, when the hook rises to 1-2 meters away from the boom, automatically cut off the lifting power supply, to prevent the hook from continuing to accompany Peisheng.

There is also the problem of two tower cranes colliding in height, the safety of which you sent me, thank you.

than the heart] enter** to view, dear.

I went in, I don't understand.

This is a very standard industry norm.

It is recommended to contact a professional to deal with it.

If you don't understand, you can let the installation tower crane personnel check it, pro.
