Some excavatorare born to build, helping new buildings rise; Some excavatorare dedicated to destruction, tearing down old buildings. Dry demolition of excavators, the platform pay is much higher than the general, and most of the use of the contract system, the salary of the machine is often more than 10,000 yuan. The reason why the cost is so high is because demolition is a high-risk operation, which not only tests the courage and technology of the machine operator, but also tests the judgment and experience of the driver on the actual situation. If you want to make a living in this field, you must understand the relevant experience and skills.
What equipment are used in demolition operations?

As the saying goes, "there is no diamond, do not hold the porcelain work ", to complete the demolition of this high-tech and difficult task, we must have the guy in hand. Common demolition equipment has special demolition machine, crushing hammer excavator, dynamic compaction machine, different equipment is suitable for different working conditions.

Demolition machine is a construction machinery specially designed for demolition, and the difference between ordinary excavators is mainly in the boom and accessories. Demolition machine with a three-section extension arm, the working range can cover 5 to 10 stories high; The front end is usually equipped with powerful hydraulic pliers that can cut through steel and cement, tearing the building to pieces.

The excavatorwith the crushing hammer is widely used in the demolition operation, and it is the main demolition equipment for low-rise buildings. Under the heavy blow of the hydraulic crushing hammer, the steel and cement have no power to resist.

Hanging weight hammer dynamic compaction machine is mainly used in soil compaction operations, for the bottom of the building, it also has a magical demolition effect. When the huge hammer hit the building, the damage was shocking.

What are the positions of demolition work?
The most common position of demolishing a building is that the excavatorstands downstairs and uses its big arms to contact the building. For the demolition machine is generally from the top down layer by layer, as long as the distance from the building is generally safer. The crushing hammer and dynamic compaction machine are generally at the bottom and middle of the building, and special attention needs to be paid to the sudden toppling of the building.

In many demolition operations, we often see excavatorbeing lifted to high-altitude buildings and dismantled from top to bottom. Although this is safer than the bottom of the hollowing out, but high-altitude work also has great hidden dangers, the slightest careless building floor collapse, the excavator will face great risk.

There is also a special posture, for the special building of high-altitude smoke pipe, the excavatoris too dangerous to be dismantled below, and it can not be settled above, so people generally use a crane to lift the excavator and let the excavator work in the air. This position requires the use of a small excavator, the driver must have extremely high courage and technology, and the average person does not dare to earn this money.

Precautions for demolition operations
Safety measures must be taken at the demolition site. Excavators should have protective devices, site personnel should wear safety hats, and safety belts for high-altitude work. Set up eye-catching safety signs on the site, do a good job of safety maintenance, non-staff are not allowed to enter.
Before construction and demolition, the surrounding environment should be checked and cleaned, and the surrounding pipe network, line, water supply, gas and power supply, underground buildings and other safety hazards should be eliminated.
The demolition site should be directed by a special person, the risk should be adequately estimated, and the behavior exceeding the safety limit should be resolutely eliminated.
