2. Glossary

(1) Climbing tower crane: With the completion of the new floor of the building, a crane that uses its own climbing frame and hydraulic climbing mechanism to gradually climb to the new floor.

(2) Fixed crane: a tower crane that is independent or attached to a building, and its lifting capacity comes from its own telescopic mechanism.

(3) Mobile crane: The foundation of the tower crane is crawler or crawler base, which can provide a larger working range.

3, structure, form type, advantage

Depending on the design manufacturer and the purpose of use, QTD tower cranes can be divided into fixed tower cranes that can be climbed in small spaces or elevators, or mobile mobile QTD tower cranes that are fixed on railcars or crawler vehicles. The top of the QTD tower crane is equipped with a rotatable girder or outrigger. The driver station is located on the turntable.QTDThe power for rotating, lifting and moving tower cranes comes from electric, hydraulic or diesel machinery. Common forms of tower cranes can be divided into three categories: climbing, fixed and mobile tower cranes.

4. Place of use (work), industry, type of work and related working environment

QTD tower cranes are widely used in building and construction industries. Due to its use, the landscape of many cities has changed. Because of its operation mode after lifting the goods, it still needs to carry out horizontal, horizontal, slewing, lifting, introduction and other units or mixed operations when necessary, because it is operated under various loads and is extremely dangerous to move. Therefore, in the "Labor Safety and Health Law", it is clearly defined as a dangerous machine.

 

Harm

1. Potential hazards, disaster types, and disaster prevention measures (safety facilities)

The main hazards of QTD tower cranes come from human error and improper operation, poor maintenance and repair, mechanical failure and improper assembly, poor design materials, weather and other irresistible accidents on foreign construction sites. Improper lifting of the crane, incorrect lifting method and load, insufficient foundation strength or support strength of the fixed crane, incorrect method of supporting the crane, insufficient knowledge or training of operators, interference with safety devices or limit switches, failure to provide easy-to-operate-Understand the instructions for use and operate the machine in strong winds. The main type of disaster is falling disaster. Disaster prevention measures are to carry out various inspection operations according to regulations and strictly abide by operation procedures.

2. Structure, operation and functional principles of safety devices

QTDThe safety device of the tower crane includes anti-roll device and anti-roll alarm device, anti-overload device and safety valve or check valve. Its function is to ensure that when the crane exceeds the capacity range, it can automatically restrict the use or issue an alarm. The anti-overload device generally adopts a limit switch, and the anti-overload device adopts a mechanical, hydraulic, electrical or electronic type.
