OIL DISK BRAKES - COMPLETELY SEALED, ADJUSTMENT FREE

Oil, air and spring located on each tandem wheel to eliminate the braking powertrain loads and reduce maintenance time. The large braking surface area ensures reliable braking and prolongs the service life until recovery.

FRONT BRIDGE WITH CAT LIVE SPINDLE DESIGN

Cat sealed spindle protects bearings from contamination and lubricates them with light oil to reduce maintenance and operating costs. The larger tapered roller bearing is outside where the load is higher, which prolongs the life of the bearing.

POWER MANAGEMENT

The Cat C7 engine with ACERT technology uses electronic control, accurate fuel delivery and control of purified air to provide outstanding performance and reduce emissions. Variable horsepower (VHP) power is standard to provide more power in high gears. Electronic throttle control provides easier, more accurate and stable throttle operation. Motor over-speed protection prevents shifting to downshift until an acceptable safe driving speed is established.

BALANCED FLOW, INDEPENDENT OIL SUPPLY

Hydraulic flow is proportional to ensure simultaneous operation of all units. Independent oil supply prevents cross-contamination and ensures proper cooling of the oil, which means less heat build-up and longer component life.

VALVE CONTROL VALVES

Provide an outstanding “feel” for the operator and a predictable system response for unsurpassed machine control. To ensure precise blade adjustment, shut-off valves are integrated into all control valves. Linear safety valves are also integrated in separate control valves to protect the cylinders from overpressure.

LOAD HYDRAULICS

A load-sensing variable displacement pump and advanced hydraulic valves provide superior attachment control and improved machine performance. Constant matching of the hydraulic flow and pressure with the power consumption creates less heat and reduces energy consumption.

PERMANENT AND FORECAST MOVEMENT

The valves of the hydraulic system are specifically designed for each hydraulic function of the motor grader. They compensate for differences in flow requirements depending on the size of the cylinder and the difference in surface volume between the end of the rod (blue) and the end of the cylinder (red) of the cylinder. The result is predictable, consistent hydraulic speeds when the cylinder is extended or retracted.

FRAME STRUCTURE - PROVIDES CONDITION AND STRENGTH

The front frame is a continuous design of the upper and lower plates. A box-section flange design removes weld seams from high voltage areas, increasing reliability and durability. The rear frame design has two box-section channels with a fully welded differential case for a robust working platform. An integrated bumper ties the rear frame together to withstand high loads.

BOX, CIRCLE AND MOLBORD

The traction device of the K series is designed to provide high strength and optimum durability for any application. Circle withstands high stress loads. Raised wear surfaces prevent round tooth wear on the drawbar. 64 evenly distributed teeth of a circle are cut off with a flame and hardened under the influence of heat to resist wear, and the circle is attached to the drawbar with four support shoes for maximum support. The blade provides optimal curvature and a large gap in the throat, which helps to quickly and effectively move the soil of all types. These functions provide excellent load distribution and minimal material accumulation in a circular area, allowing large loads of blades to be freely moved.

LIFT BATTERIES

This additional feature uses batteries that help absorb shock loads to the blade, providing vertical movement of the blade. Blade lift batteries reduce unnecessary wear and help avoid unintentional movement of the machine to increase operator safety.

OPTIONS MOLBORDOV

The standard blade length is 3.7 m (12 feet). Blade extenders are available to increase the surface area of ​​the blade and extend reach.

GROUND INSTRUMENTS
