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.
