About history

The Japanese engineering corporation Komatsu traces its history back to 1921, with the construction workshop of Meitaro Takeuchi, which gradually grew into a large manufacturer of equipment for the construction industry, as well as for the coal and mining industries.

Nowadays, it produces a wide range of road construction equipment, bulldozers, excavators, forklifts, pipe layers, mining equipment, presses and other industrial equipment. The company has factories all over the world.

The twenty-fifth and largest in the history of the corporation was opened in June 2010 in the city of Yaroslavl. This is the first foreign enterprise in Russia that performs the full cycle of assembly of construction equipment. In addition, the company has a joint venture, Kranex/Komatsu, operating at the Ivanovo Excavator Plant.

Performances

Based on the basic WB 93 machine, the manufacturer produces a number of modified models. To the described excavator you can add Komatsu WB93R 2-5 generations, WB97S-5.

They all have similar operating parameters, differing only in the performance of the hydraulic system and the equipment of electronic components.

The most modernized model is WB97.

In it, the developers have implemented progressive solutions and new technologies that have proven themselves well in other devices.

Reviews from owners and machine operators about Komatsu WB93R-5EO

Many people who have gained experience working with an excavator of this model note the following advantages. This is simplicity and convenience of repair and maintenance. The hinged hood provides access to the engine compartment, ensuring quick inspection and quality service. This is the reliability and durability of the hydraulic system: the hydraulic hose connection elements have a sealed joint surface. Hydraulics are strong; The rear axle differential lock helps a lot. The backhoe control levers are very comfortable. Joystick too, although you need to get used to it and get used to it. The glass latches on the doors are made very well and intelligently - simple and reliable.

About the disadvantages noted by machine operators. The loader on Komatsu WB93R-5EO works slower than on Odnoklassniki. The design of the bucket is such that when working with soil, the space behind the cylinders quickly becomes clogged. There is a real lack of a normal, spacious glove compartment. The one that is there doesn’t really fit lunch and drinks, not to mention other things that are larger in size. The seat is generally comfortable, but the back does not recline - accordingly, you cannot stretch out and relax in your free time. Since the windshield washer pump has only one pump, the liquid flows simultaneously onto both windows - front and rear. Therefore, it is consumed much faster. There are complaints about the visibility from the cabin - due to the exhaust pipe, which is located on the side, near the pillar - it interferes most at intersections, when turning right.
