Komatsu WB-93S-5EO is a Japanese representative in the field of production of combined loaders and excavators. This versatile vehicle is equipped with a wheeled chassis and all-wheel drive. It performs earthmoving and loading works equally fast, which together with its maneuverability and reliability has led to its mass use in industry, construction and municipal services.
“Komatsu” 93-5E0 is mostly found on construction sites, where there is always work for it.
In addition to the standard implements, additional implements can be installed on the machine, thereby expanding the Komatsu's functionality.
Japanese machine builders stayed true to their traditions and made a truly robust machine. The wheeled chassis allows the excavator to get to the place of work on its own, while a tractor is needed only to move the equipment over a distance of more than 50 km. Additional information! The excavator boom is designed in an S-shape. The design is optimal for working in confined spaces and also contributes to increased breakout force and acceptable load distribution.
Under the hood, Komatsu has a diesel engine made in-house. It is an inline four-cylinder engine with a water cooling system. Fuel injection takes place immediately into the cylinders, and the process is controlled by electronics. To increase output, the power system is equipped with a turbocharger with an intermediate heat exchanger.
The chassis power transmission is represented by torque converter, manual transmission and drive axles. The gearbox provides 4 speeds for forward movement. To drive the machine backwards, reverse is used, which is activated by a servo-controlled reverse switch of Power Shuttle type. A torque converter provides gear shifting under load.
The chassis is fitted with level wheels. A hydrostatic steering system with feedback and priority fluid valve is responsible for turning the hubs. Thanks to this solution, the loader is highly maneuverable and can move straight ahead, track-to-track, and in crab-steer mode.
“Komatsu received reinforced axles.
The SyncroSystem closed-center hydraulic system ensures precise positioning when moving the working tools in 3 planes. The working fluid is pumped by a variable displacement axial piston pump. Every minute it delivers up to 165 liters of hydraulic oil under pressure of 25 MPa into the pressure line. The hydraulic system is controlled by the main valve with a flow divider of modular type, independent of load (LIFD). The developers have provided 2 operating modes: power and economic.
To increase the performance of the front loader, it is possible to activate the “speed boost” function for greater oil pump output.
The WB 93 model is built according to the classic technology inherent in the class of loader combined with excavator.
The lifting unit has been equipped with a parallel movement function to make it easier to operate the loading mechanism. The operator does not need to constantly monitor the bucket position to prevent material from falling out. Loading equipment characteristics:
In the basic configuration, the excavator will be fitted with a backhoe with a capacity of 0.6 m³. The bucket is mounted on a telescopic handle and original S-shaped boom.
The cab is equipped with a fully adjustable seat with seat belt. Access is possible from the right or left side through fully openable doors. Front, rear windshields are equipped with wipers and washers. The steering column can be adjusted in height and angle of inclination. The cabin accommodates several storage compartments for personal items, one of which can be locked with a key. Additional information! The cab is equipped with a branched ventilation system with ten air ducts. However, air conditioning is only available as an option. Operator safety is ensured by the cab's load-bearing frame, which protects the driver in the event of a rollover or heavy objects falling on the roof. The support frame is ROPS/FOPS compliant.
In addition to the standard loading and excavation equipment, additional equipment can be mounted on the chassis.
A 4-in-1 universal bucket, bulldozer-type moldboard, and mobile hammer are mounted on the standard loading equipment. Hydraulic coupling is provided for quick change of implements.
Based on the base machine WB 93, the manufacturer produces a number of modified models. Komatsu WB93R 2-5 generations, WB97S-5 can be added to the described excavator. They all have similar operating parameters, differing only in hydraulic performance and electronic components. The most modernized model is the WB97. In it, the developers have implemented progressive solutions and new technologies that have proved themselves perfectly in other devices.
The manufacturer tried to make the machine unpretentious and easy to maintain. The number of joints in the design of the loader and earthmoving equipment has been reduced, thus reducing the time required for daily maintenance. In addition, the intervals between numbered maintenance are slightly extended due to the use of high-quality and durable materials. The Komtrax monitoring system is installed in the basic version of the truck. It allows the owner to receive information about the condition of the equipment and its location at any time.
A new Komatsu WB93S-5 costs approximately 90-110 thousand dollars. The price depends on the model year, technical equipment, and equipment. On the secondary market the machine can be found for 3-4 million rubles. Here the price is formed more by mileage and equipment. A machine with exhausted resource is inexpensive, but its operating costs are higher.
Komatsu equipment is a justified option in the first stages of large projects. High productivity, durability, quick repair and maintenance are the qualities of the versatile Japanese machine that make it valued on construction sites around the world.
