Design of motor grader GS-14.02
This equipment is equipped with blades (bulldozer and rotary), allowing for a wide grip during operation. The same capability is achieved with an articulated frame.
The full-rotating grader blade is fixed between the rear and front axles. This design allows you to perform work while reversing. Blades can be replaced with rippers (scarifier or picker). The presence of a set of removable tools is one of the design features of the GS-14.02 motor grader.
The equipment also contains the following components:
Motor grader GS-14.02
- The mechanical transmission allows the vehicle to be used for work even at high altitudes;
- The 2-circuit brake system operates hydraulically (with a constant volume pump) and has a spare power source;
- Additionally, the motor grader is equipped with a parking brake;
- in hydraulics, in addition to 6 amplifiers for the main equipment, there are also 4 electrical modules for additional equipment;
- management of the dumps is automated and carried out using balancers and sensors.
The efficiency of a motor grader directly depends on the features of the installed engine.

Distinctive features of the series
The GS-14.03 grader is similar in design and technical solutions to model 14.02.
Higher operational capabilities of the unit are ensured by the use of parts and mechanisms produced by leading German companies in critical components.
The BF04M1013FC diesel engine from DEUTZ AG with a power of 117 kW provides a 17% increase in torque on the shaft while reducing fuel consumption.
Automatic transmission In the WG160 from ZF, the tandem bogie TAP 5501.105 (BRA) from NAF with a No-Spin locking differential increases the productivity and reliability of the grader.
An equally important role in increasing the effectiveness of the use of GS-14.03 is played by:
- GLONASS module, automatic leveling system TOPCON/LIECA in 2D and 3D versions;
- automated central unit for supplying lubricant to LINCOLN joints;
- video cameras for monitoring the working area;
- heated mirrors and fuel filters.
The GS grader series includes the following machines:
- Light class 10.01 and 10.07 - used in the construction and maintenance of roads, used in the public sector.
- Average 14.02 and 14.03.
- Heavy graders 18.07 and 25.09 - for large projects including excavation and profiling work.
Units with the ability to operate in harsh conditions, built into the design stage, are universal in use. They are the basis for a more efficient and productive series of graders from Bryansk machine builders TG.
Hydraulic system
The hydraulic system installed on the GS-14.02 motor grader operates through constant volume pumps and has an additional unloading device that is activated when the control handle is in the neutral position.
The working bodies are controlled by manual hydraulic distributors - there are 6 of them in the system. Another 4 (but already electric) perform related operations.
