Tower Crane for Metro Railway Station

Tower Crane for Metro Railway Station

The tower crane comprises a number of mast sections that are highly interchangeable. The elaborate structure makes it easy for mounting and dismounting.

The main support of the mast section has both end faces processed by the jig boring machine to live up to the required flatness of both ends and verticality

of the whole mast section, thereby improving the overall performance of the tower crane.

The metal parts are jointed by carbon dioxide gas shielded Arc Welding to achieve a tough and reliable structure.

Product quality is further guaranteed by the advanced inspection devices, such as the ultrasonic fault detector and sound level meter.

A complete set of safe and reliable hydraulic jacking device is adopted for self-elevating. The tower crane goes up and down steadily and the

lifting height varies with the building height. These merits make the lifting equipment ideal for high-rise construction.

• Trolleying mechanism power: 3.7/2.2 KW

• Types of tower crane: stationary crane with embedded outriggers, stationary crane with embedded bolts, stationary crane with under-frame and mobile tower crane.

2. Electrical control system

Types of tower crane: stationary crane with embedded outriggers, stationary crane with embedded bolts, stationary crane with under-frame and mobile tower crane.

3. Technical features

• The crane boasts of multiple operation modes and wide application. The crane can work in different forms: stationary crane with embedded outriggers, stationary crane with under-frame, stationary crane with embedded bolts and crane anchored to wall, thus being applicable to various construction projects.

• The complete machine adopts internationally well-received beautiful shape;

• The crane features high working speed and excellent speed regulation performance. Stepless speed regulation by frequency control, the world's most advanced solution, is adopted for the trolleying mechanism and slewing mechanism, thus ensuring more stable and reliable operation ;

• The cab is independently installed externally with good vision and large inner space, thus offering a good working environment for operators;

• A variety of safety devices are equipped, which are all mechanical or mechatronic products that are applicable to severe working conditions, so as to ensure the tower crane's reliable operation.
