Product Features
Performance parameters and technical index reach both domestic and international advanced level.
The electrical control system enjoys better reliability and safety. It is produced by professional manufacturers with advanced technology, the electrical components lives 3 or 4 times longer than that of products around market, less faults, easier maintenance and repair as well as reliable and safe operation.
• The crane boasts multiple operation modes and is of 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, slice structure for cost saving purpose;
• The crane features high working speed and excellent speed regulation performance. Stepless speed regulation up to 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 provides enough space, thus offeringgood 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.
