          Tower Crane

          The tower crane is a product used at major construction sites for vertical and horizontal transportation applications. It consists of lifting, slewing, luffing and jacking mechanisms, which can work respectively or together for higher efficiency. The jacking mechanism is used to make the tower rise or descend. The lifting mechanism adopts a multi-speed motor to realize fast speed, medium speed and slow speed, so it can be used in different working conditions. The slewing and luffing mechanisms are very reliable and operate easily and quickly.

          The tower crane is equipped with many protection devices to ensure safe operation, such as a lifting load limiter, moment limiter, lifting height limiter, trolley travel limiter, and slewing limiter. Rest platform and guardrails are also available. The cab independently located on the side is spacious, aesthetically pleasing, easy to operate, and offers the driver great visibility.

          • Inner Climbing Tower Crane The inner climbing tower crane is made up of special base sections, climbing frames and climbing devices. By the aid of the climbing device, the tower crane raises itself by climbing up as the building rises.
          • Topless Tower Crane The topless tower crane has achieved an internationally advanced level in terms of performance. For instance, its maximum working range reaches 74m, which results in extended working space.
          • Trailer Concrete Pump HBT100-16-181RSBoth the main pumping circuit and "S" valve circuit are open-circuit. They are separately driven by a pump, which makes the two circuits independent to each other.
          • Trailer Concrete Pump HBT80-13-161RSRealizing operation through the menu and displaying text on the large screen effectively reduce operating buttons. The electrical cabinet reaches IP65 protection grade ...
