Characteristics of RUN Chen Tower Crane

The various advanced performance parameters, lifting torque, lifting height, work amplitude, wide operating space, high efficiency.

The whole crane has the advantages of beautiful appearance, light steel structure, well-selected materials, pre-treatment by shot blasting and antirust; the mast section adopts welding and cutting of tire tools, good interchangeability; , The wind resistance is small; the top of the tower is forward-tilted, the force is simple; the bolt and the high-strength bolt are used for connection and disassembly; the side-mounted driver's cabin has wide vision and the driver's seat can be freely adjusted according to human needs and is comfortable to operate.

The crane has a fixed, attached, climb and other types of work to meet the urban high-rise buildings, industrial plants, power stations dams, bridges and other construction needs.

Hoisting mechanism adopts with high speed and low speed motor speed control technology to obtain the ideal lifting speed and load slow place. Rotary body torque motor drive, traction mechanism using two-speed motor speed control technology, work smoothly, in place accurate. Travel agencies using hydraulic coupling, starting a smooth brake.

The electric control system adopts international common type, low-voltage electrical appliances imported electrical components, modular building, rail-rail installation. Manipulated by two cross-shaped master controllers and push-button switches centered on the driver's cab. The whole cabinet 380V-440V (50Hz-60Hz) power supply.
According to customer needs to install a variety of safety monitoring devices, with torque, weight, amplitude, height display, but also alarm, self-locking and other functions.

 The tower crane working level A4, working conditions at the top of tower crane pressure is not more than 250Pa (wind speed not more than 20m / s). In the non-working state, the top wind pressure is not greater than 1100Pa (wind speed is not greater than 42m / s). When the top height of the tower crane is greater than 100m, the top wind pressure is not more than 1300Pa (wind speed not greater than 45.6m / s).

Jack frame and mast section

The hydraulic jacking system help to lift the tower by adding mast sections. In this way, the crane can rise with a building's ascending. Hoisting capacity of our tower crane always remains the same at different heights. The driver cabin is installed at the top of the tower to ensure full view and a comfortable and convenient working environment with air-condition.

Mechanism and slewing table

The hoisting mechanism is driven by a three-speed motor to enable low-speed heavy loading, high-speed light loading, ideal idling speed and accurate positioning. Controlled by frequency converters, the hoisting mechanism is characterized by high working efficiency, long lifetime, low maintenance rate and comfortable manipulation.
 
Equipped with a hydraulic coupler, a driven reducer and a disc brake, the slewing mechanism has high overload capacity, and it still functions well when starting up at heavy load. Hence, smoother startup and brake more reliable and safe operation can be guaranteed.




Electric parts

  Electrical control system of our topkit tower crane features reasonable design and reliable performance. Major electrical apparatus elements such as contactors and intermediate relays are purchased from Schneider, which is a world famous company.
  For safety and reliability of operation, the hammerhead tower crane is also designed with various safety devices including load moment limiter, overload limiter, slewing limiter, trolley travel limiter and height limiter.


Hoist Boom And Delivery

  As for assembly of the self erector, quick couplers are applied when installing the jib, the balance arm, the slewing mechanism and the tower body to ensure high efficiency, convenience and accurate positioning. As a result, labor intensity and risks are reduced significantly and hoisting time of a truck crane is saved greatly. Plate type mast sections are assembled using fishplates and pins, which leads to good interchangeability, easy warehousing and transportation and less cost.
