The History of Komatsu Crane

Komatsu Limited is a Japanese engineering company. The headquarters is in Tokyo. The company is ranked 453 in the Fortune Global 500 (2011).


It all started in 1894, when Meitaro Takeuch began work in a copper mine and founded. The next step in the history of the Komatsu empire was the opening in 1917 of a small main activity of which was the production of machine tools and equipment for the coal and mining industries. The name of the new company was named after a small town in western Japan, which became its place of residence for many years, until 1951, when the head office of Komatsu moved to Tokyo.


The successful work and dynamic development of Komatsu Iron Works made it possible to separate the company into a separate independent enterprise - Komatsu Ltd - which happened on May 13, 1921 - this date is considered the birthday of Komatsu. In 1924, the first Japanese press machine was produced, and after a very short time, Komatsu Ltd reached the size that allowed it to start manufacturing construction equipment.

Today, Komatsu is an international concern with 47 manufacturing plants and 144 sales and service companies located on all continents. Komatsu employs nearly 40,000 people. The Komatsu brand is familiar to all buyers of mining, construction, forestry, lifting and transport machinery and equipment without exception. About 460,000 pieces of equipment manufactured under the Komatsu brand are in operation worldwide. Exceptional reliability, unique power and performance are the hallmarks of Japanese Komatsu technology.

Komatsu produces various road construction equipment (bulldozers, excavators), forklift trucks, pipelayers, mining equipment, presses and other industrial equipment, military equipment, etc. The company has 22 factories around the world.


The Komatsu Group comprises 188 companies (Komatsu Ltd.; Omatsu Ltd.; 145 consolidated subsidiaries; 42 equity group companies)

The new design of the five-stage boom has high rigidity. The lift height has been increased, while ensuring good machine stability and minimal boom deflection.

• Maximum boom length: 32 m

• Maximum lifting height in single file: 47.7 m

• Maximum total rated load: 26t x 3.0m

• Slight overhang of the five-stage boom over the front of the chassis

The LW250 model is equipped with a short five-stage boom, which achieves a small boom overhang over the front of the chassis. Compared to conventional machines with a lifting capacity of 25 t, the boom overhang can be approximately 2 m shorter, which significantly reduces the overall length of the machine.

• The minimum turning radius of the rear and front parts of the platform among machines of this class.

The compactness of each individual design determines the compactness of the entire machine.

• Turning radius of the back of the platform: 2.95 m

• Platform front turning radius: 2.0 m

• Four steering modes enable tight turns

The steering system, making full use of the compact design of the machine for working in confined spaces, has four steering modes: using two front wheels, using two rear wheels, turning all four wheels of the machine in one direction (crab mode), turning the front wheels in one side, and the rear wheels in the opposite direction (steering mode).


The LW250 crane also has a rearward steering override function that allows the steering wheel to be turned in the same direction as when moving forward.
