Kitagawa JCL1000NK

Kitagawa set new standards in its domestic market with the introduction of JCL1000NK in 2018. Thanks to its MS25 tower system, combined with the standard M23 system, which both has the same dimensions of 2.05m x 2.05m. This allows a free-standing height of 56m to be achieved. The tower crane is compact with a tail radius of only 6.7m and a lifting capacity of 33 tons. The tipping load is 16 tonnes at 45m jib.

The JCL1000NK inherits the popular NK series concepts of “simple,” “lightweight,” and “compact,” and achieves reduced running costs such as transportation and assembly costs, as well as a reduced reaction force. It is one of the largest 1000tm models in Japan that meets the demand for shortening the construction period of buildings.

Product Description

For the ease of dismantling, the roof-mounted recovery derrick all components of the upper crane can be disassembled into pieces to a weight of a maximum of 10 tonnes. It is typical for Japanese tower cranes manufacturers to design a rigid tower system that requires no counterweight.

The standard 145 kW hoisting winch allows a hoisting speed of 102 m/min.

Also, the Japanese have reduced the erection weight with the climbing frame of the Kitagawa JCL1000NK can be split into two – with the upper weighing 8.8 tonnes and the lower weighing 6.7 tonnes.
