Chassis

As standard, a DZ 98 motor grader gearbox with 6 steps in both directions is installed, which allows you to quickly and efficiently cope with the tasks. When working in difficult conditions, the manufacturer recommends the use of a mechanical transmission, which allows you to create a reserve of power and increase efficiency. The car can move forward at a speed of 41 km / h, backward - 47 km / h. The gearbox is equipped with all-wheel drive or only on the rear axle.

The transmission includes:

• intermediate cardan speeds on axles;
• "Handbrake" tape;
• transfer gearbox for driving two axles with a "handbrake";
• dry 2-disc closed-type clutch with hydraulic servo and brake mechanism;
• 1-row hydraulic pump drive gearbox with flexible coupling.

The undercarriage of the motor grader DZ 98 with a 1x3x3 drive is installed on three drive axles. The front axle is controlled by the steering wheel. The main gear is represented by a conical 1-speed unit. The composition of the "hodovka" does not include differentials, and the axle shafts are mounted unloaded. Brake units are multi-disc, they function in oil, are made of metal and ceramics. To increase efficiency and traction characteristics, the use of cylindrical 1-stage side gearboxes is envisaged.

Suspensions for a pair of axles are made with balancers in the form of rods, and a hinge on the front axle serves as a counterweight. They are designed for pumping in different directions. "Handbrake" is able to hold the car on a base slope of up to 15 degrees.

The gearbox of the DZ 98 motor grader allows you to develop a fairly high speed, and it will take 15 m to stop completely, provided that you are moving at 30 km / h.

Operator's cab

The design of the cabin resembles a hexagon, which guarantees a large viewing angle and safety. The top of the machine can be put on and taken off at any time, making it easy to transport on a low bed trailer or in a van.

The interior space is characterized by comfort and ergonomics. The seat is adjustable in several directions. An air conditioner is optionally installed, which creates the required microclimate in the hot season.

The excellent technical characteristics of the DZ 98 grader are maintained when working in any climate. To optimize the performance of the grader, the installation of auxiliary units and functions is provided. The southern areas will require air conditioning, while the northern areas will require pre-heaters, additional interior insulation and a high-output heating system.

Ease of operation and maintenance

The device of the motor grader DZ 98 provides easy access to the main service points. Under the hood is the engine compartment, silencer and fuel filter. The one-piece hood eliminates the appearance of a large amount of noise and vibration during operation.

The front axle can be connected and disconnected, which guarantees economy in various operating conditions.

The main indicators of the car include:

Maintenance of the motor grader DZ 98 is carried out in accordance with the intervals established in the passport.

Working equipment

In addition to standard equipment, additional equipment can be installed. The manufacturer has provided various options for use in many areas of activity, which expands the scope of the machine and its efficiency. To loosen the soil, a ripper-scarifier is mounted in the rear of the equipment. An auxiliary wing is hung on the grader blade, which is necessary when clearing the road from snow, and cleaning behind the fences is carried out using an auxiliary side blade.

Additional working bodies are:

• ripper;
• bulldozer blade;
• tooling for track arrangement;
• snow dump;
• pickaxe.

Technical characteristics of the grader DZ 98 when working with a track-laying body are presented:

The bulldozer blade allows you to clear a strip 3.2 m wide, capturing 2.57 m3 of material. The height of the organ is 0.97 m, the cutting angle is 55 degrees, and the digging depth is 0.11 m.

The ripping equipment is equipped with five tines, it can loosen to a depth of 0.23 m and cover a surface of 1.8 m.

The control of the motor grader DZ 98 with a grader blade is standard. The blade is equipped with a knife mounted on the supporting structure of the special equipment, it can be rotated in all planes. The main purpose is to level the artificially created surface when laying asphalt pavement. In cold weather, the working body copes with cleaning the surface from snow and ice.
