tower crane is the latest domestic hoisting and transporting machinery designed by our company by fully utilizing group technology, combined design technology and finite element analysis technology, using "tower crane microcomputer design platform" as a tool.

The machine is a horizontal boom, trolley luffing, upper-slewing hydraulic jack-up crane. The maximum lifting capacity is 6t; the rated lifting moment is 800kN·m; the maximum lifting moment is 843kN·m.

Features of the machine:

(1) The performance parameters and technical indicators have reached the domestic leading and international advanced level, and the maximum working range is 60 meters, which increases the working space of the tower crane.

(2) The appearance of the whole machine is an international popular form, which is beautiful and generous.

(3) There are many working methods and a wide range of applications. There are two working methods of fixed foundation and external wall attachment, which are suitable for various construction objects; the independent lifting height is 40 meters, and the attachment height is 150 meters.

(4) High working speed, good speed regulation performance, stable work and high efficiency.

The hoisting mechanism adopts a multi-speed winding motor and a single-speed ratio reducer, which can achieve heavy load low speed and light load high speed.

The trolley luffing mechanism pulls the trolley to luff on the horizontal arm, which has a good installation performance.

The slewing mechanism adopts a winding motor and a planetary gear reducer, and is equipped with a fluid coupling, which has high load-bearing capacity, stable start-up, reliable work, and has the function of anti-wind in place.

(5) The boom is suspended by rigid double tie rods, with good rigidity, light weight, small section, small wind resistance, uniform force, and beautiful appearance.

(6) Various safety devices are complete to ensure safe and reliable work.

(7) The driver's cab is placed on its side independently, with a good view, which creates a good working environment for the operator.

(8) Easy to use and simple to maintain.

The machine has a total installed capacity of 34.8kW, which is widely used in large-scale construction projects such as high-rise hotels, residential buildings, and industrial buildings. It is an ideal construction machinery for the majority of construction companies.
