As a result of the desire of developers to combine the functions of warehouse and construction equipment in one machine, backhoe loaders appeared. These versatile machines quickly gained popularity. In an effort to expand their market share, companies offer consumers more and more technically advanced equipment. Such a giant of the engineering industry as Komatsu Ltd. does not lag behind its competitors. Its catalog contains several models, from which the buyer has the opportunity to choose the most suitable one in terms of configuration and characteristics.
Komatsu WB-93R-5EO
The youngest in the family of this type of equipment produced by a well-known Japanese manufacturer is the Komatsu WB-93R-5EO backhoe loader. The technical characteristics of the machine comply with strict European standards. The components and assemblies used in the design provide the WB-93R-5EO model with high efficiency. Its parameters look like this:
- Engine modification Komatsu SAA4D104E-1. The four-cylinder power unit runs on diesel fuel and has a displacement of 4485 cc. cm develops a maximum power of 100.6 hp. With. An effective liquid cooling system reliably protects the motor from overheating in difficult operating conditions. Taking into account the operation of equipment in regions with cold climates, the starting system is equipped with a device for preheating the air entering the intake manifold.
- The operating weight of the machine according to the standard is 8070 kg, but may vary depending on the replacement equipment installed on it.
- The SyncroSystem CLSS (closed center) hydraulic system has two operating modes: economical and maximum power. It provides precise control of the working parts of the backhoe loader, regardless of whether it is static or in motion. A working pressure of 250 bar is provided by axial piston pumps.
- The steering system is hydrostatic. It turns the front wheels and provides a turning radius of 5450 mm on the outer corner of the front bucket without using brakes. If you apply the brakes, the turning radius is reduced to 4950 mm.
- The Power Shuttle transmission has four gear stages and, depending on the selected mode, transmits torque to 2 or 4 wheels. The gear shift system is electro-hydraulic. Reinforced axles can withstand high dynamic loads: the front axle is 8500 dN, and the rear axle is 7600 dN.
- The front loading bucket of the standard type with a width of 2320 mm has a capacity of 1.03 cubic meters. meters. Its load capacity is: 5300 kg at ground level and 3900 kg at a maximum height of 4290 mm. Breakout force at the leading edge is 6500 kg.
- The backhoe is mounted on an S-shaped boom, which is mounted offset, left or right, relative to the longitudinal axis of the Komatsu WB-93R-5EO backhoe loader. Maximum excavation depth: 4540 mm with conventional boom and 5650 mm with telescopic boom. The load is lifted to a height of 5800 and 6405 mm, respectively.
- The steel frame, made of box-section profiles, has high strength and is able to withstand significant loads when the machine operates in various conditions.
- The distance between the wheel axles is 2175 mm and the ground clearance is 430 mm, designed for driving on rough terrain.
- The Komtrax monitoring system allows you to receive real-time information about where equipment is working, how much time it takes to complete assigned tasks and, importantly, to learn about cases of unauthorized use.
The technical solutions used in the design have proven themselves to be the best. They provide the machine with a long service life, good mobility on work sites and enviable fuel efficiency, thanks to which operating costs are significantly reduced.
The versatility of Japanese backhoe loaders
With the help of standard and optional attachments, Komatsu equipment is capable of performing many technological operations:
- digging and arrangement of holes of any configuration (pits, trenches);
- landscape surface planning (filling, removing and profiling soil);
- laying drainage and road surface layers;
- loading of bulk materials (including waste removal);
- creation of vertical holes (for supports, trees, piles, pillars);
- assistance during installation work (laying communications);
- demolition of buildings;
- snow removal;
- transportation of goods (including equipment);
- towing.
This list convincingly proves the effectiveness of excavators with a loader function.

Komatsu WB-93S-5EO
The Komatsu WB-93S-5EO backhoe loader is also close in technical characteristics to the model described above. However, its design places emphasis on increasing cross-country ability. Among the main differences of this modification:
- High ground clearance of 475 mm.
- Wheelbase increased to 2215 mm.
- Larger capacity front bucket. With a width of 2420 mm, its internal volume is 1.1 cubic meters. meters. The carrying capacity of the bucket remained at the same level.
- Redesigned brake system.
- All-wheel drive system with self-locking differentials on both axles.
When working on very rough terrain and difficult soils, this model has certain advantages.
Advantages of special equipment
Komatsu equipment is constantly being improved: engineers adapt new models to the requests of real users coming from all over the world. Therefore, these backhoe loaders have found wide application in the Sverdlovsk region and are used in construction and utility work. Thanks to additional equipment, a backhoe loader in Yekaterinburg can perform an expanded range of tasks:
- Digging holes, trenches, pits;
- Cleaning embankments and snow;
- Demolition of structures;
- Loading bulk materials;
- Transportation of goods;
- Towing.
The backhoe loader has different operational characteristics depending on the selected modification of the equipment. But all models offer key benefits: multiple power modes, 360° operator visibility, quick-release bucket couplings, multiple steering modes, and more.
Backhoe loaders from Russia are not as versatile and reliable in operation as Japanese equipment, so most construction companies and utilities tend to purchase foreign models.
Komatsu WB-97S-5EO
Having retained the main advantages of the WB-93S-5EO model, the Komatsu WB-97S-5EO backhoe loader was the next step that Japanese developers took towards improving the equipment they produced. For this he received:
- Full Power Shift transmission with electronically controlled all-wheel drive system. It greatly simplified the control of the machine while moving it.
- The rear bucket boom has a modified geometry that allows excavation of soil from a depth of 6080 mm and lifting it to a height of 6675 mm.
And a number of other improvements.
