MOTOR GRADER – HMK 600 MG

HIDROMEK – HMK 600 MG

Drivetrain
The HMK 600 MG features 8 forward and 8 reverse gears! The HMK 600 MG offers its users manoeuvrability capabilities both from the steering wheel and from the joystick. The speed of the machine may be changed with the FNR button on the joystick (140kW – 160kW) and the steering movement may also be controlled by tilting the joysticks to the left or right. The joysticks also allow the operator to control the blade. Driving comfort is enhanced with automatic gear selection and cruise control equipment.

Motor
The HMK 600 MG’s Mercedes engine, with a variable horsepower feature (187 – 214 HP) compliant with Stage IIIA (Tier III) exhaust emissions, is durable in challenging working environments. The variable horsepower feature targets higher efficiency and lower fuel consumption. The hydrostatic cooling fan, which can be operated at variable speeds depending on the engine temperature, is also automatically operated in the reverse direction to clean the cooling system and thus to increase the efficiency of operation.

Hydraulic System
Hydraulic pressure may be adjusted easily thanks to closed-loop central electro-hydraulic valve, which is fed by a variable flow-rate piston pump, and thus proper power for attachments may be provided. The load-sensing feature provides hydraulic flow according to the task that the machine will be performing. This adjustable hydraulic flow reduces heat and power loss, thus the machine’s performance is improved.

Cab
The newly designed hexagonal cab of the HMK 600 MG provides the operator with a wide viewing angle, while the 7 “TFT information display in the cab allows the operator to comfortably control the machine. The operator may monitor the data to be inspected from the screen while operating the machine. In addition, the operator may see the image of the rear-view camera from this screen, and may move the machine in a controlled manner while reversing.

Frame Structure with High Strength
The HMK 600 MG’s strong frame was developed based on computer simulations and field tests. Thanks to its advanced design, the service life and durability of the machine have been improved.

Blade Platform and Attachments
The HMK 600 MG has excellent performance for a variety of tasks such as levelling, mixing, grading, digging, and ploughing of snow and ice in winter conditions. The standard blade length is 3.7 meters, and options of 4.01 and 4.31 meter blade lengths are available. Thanks to the “Clutch System”, sudden and large impacts encountered by the blade are absorbed by the clutches and damage to the blade is prevented. Clutches on the circular swivel system protect the blade against overloads by sliding over each other in the event of high forces counter-acting against the blade. The HMK 600 MG also features 2 blade accumulators that improve the strength of the blade and thus provide ease of operation for the operator by absorbing the sudden vertical shocks to the blade.
