Chitra T9 Description

Transmission components (except side gears), engine mountings and cab of the T9 bulldozer are almost completely unified with the T11 T11 tractor. The machine is used quite mobile, especially outside the streets, railroads and major airports. Given the weight of the machine, they can be transported to the place of work by helicopter. The tractor can be easily transported on supporters in urban areas and work in limited urban conditions. The machine can work in swampy terrain and other areas with a weak floor. The T9 T9 is equipped with a straight, hydrated curve blade with push-pull props between the tractor frame and track. Semi-soft three-point suspension with a flattened machine pivot axis provides high crest properties, reducing shock loads on the chassis and improving working conditions. For working in harsh climates. Among the latest innovations is the use of electro-hydraulic gearbox controls and hydraulic joystick controls.

The range is very wide, it will satisfy the needs of both the small construction company and the giant of modern industry with its tractors, bulldozers, machines for the forest industry, pipelayers and other wheeled devices.

Description and purpose

T9 T9 is a crawler bulldozer of the general-purpose 9 traction class. The production of the series is engaged in (Cheboksary). In the segment of bulldozers produced in Russia, the T9 T9 is one of the most mass-produced machines. The model is used with dozers and bulldozers of various types on industrial, street, oil and gas and hydraulic engineering sites to carry out transportation, repair, restoration, irrigation and excavation work. Model T9 T9 can operate with weak accumulation capacity in swampy terrain and areas with soil. The main purpose of the model is to move soil and materials over a distance of up to 400 m. The bulldozer has compact dimensions, which makes it easy to transport.

Chitra T9: technical properties

Chytra T9: technical specifications

Industrial bulldozers Caterpillar T9 T9 belong to the ninth traction class. This is a product of the Cheboksary company “Promtor”. The main work of the T9 T9 is the regular movement of large amounts of soil over limited distances (up to four hundred meters). This bulldozer copes with it perfectly, as it is specially adapted to work for a long time in intensive conditions. It is relatively compact and mobile. With the Mass T9 you can transport the bulldozer not only by trailer, but also by helicopter to the place of work.

T9 bulldozer in industrial, street, oil and gas and hydraulic engineering construction is used completely with bulldozer and ripper of different types or with a traction unit. They perform a wide range of works with the warm floor, transport, irrigation, repair and restoration, etc.

Special equipment of this model is used in landscape renewal during exploitation of landfills, quarries, etc.; construction of industrial and residential buildings and structures; construction of railroads and roads, bridges, airports; irrigation, hydraulic and excavation works; pipe laying; geological prospecting, oil and gas and mining industry needs.

Chitra T9 tractors are produced in climatic version Uhl and T according to GOST-1515O. According to the Pass, this bulldozer can operate with full load at ambient temperatures from t-50 to +35 degrees Celsius. In case of extreme heat or extreme frost below e-50 degrees, the tractor load must be limited. It means not to overheat the diesel engine in severe heat, and in severe frost – to drive forward and backward regularly with the hydraulic system of the attached equipment switched on.

Design characteristics

Most assemblies and units of the T9, from the engine unit and cab to gearboxes (except for axle drives), are unified with the Chetra T11 bulldozer. However, the lower weight of the T9 expands the possibilities of its use and makes the special machine mobile, especially away from roads, railroads and airports.

Helicopter transport to the construction site helps geologists and raw material industry workers who work in hard-to-reach areas. Its low weight also makes it ideal for use in wetlands and other areas with weak soil. On the other hand, the compact size of the Chetra T9 allows for trouble-free transportation in urban areas and work in cramped conditions of modern cities.

Construction specifications

The Chetra T9 is equipped with a straight shield with hydraulic steering and push rods that are positioned between the tractor frame and tracks. This design ensures high productivity. Semi-rigid three-point suspension with an extended bogie pendulum axle guarantees high traction properties, reduced shock loads on the undercarriage and improved working conditions.

The T9 design includes electro-hydraulic transmission controls and joystick controls for the hydraulic units. The diesel engine is significantly more economical than the units of the previous generation Cheboksary leveling blade. Cheetra T9 is arranged according to the principle of modular structure of all units and systems of industrial tractor – gearbox, running gear, working equipment, cooling system, cab and tractor control system. This provides simplified and convenient service during inspection and filling of all systems, as well as the possibility of removing and installing transmission units as separate modules for subsequent repair at specially equipped positions.

Modifications of Chetra T9 bulldozer

The group of Chetra T9 industrial tractors includes the following six basic modifications of “Bulldozer”:

  • T-9.01Ya- with YAMZ-23nB-2 diesel engine, hemispherical blade and specific pressure not more than 0.63 kgf/cm2;
  • T-9.01YAM – with YaMZ-23nB-2 diesel engine, straight blade and specific pressure of no more than 0.38 kgf/cm2;
  • T-9.01YAMP – with YaMZ-236nB-2 diesel engine, rotating blade and specific pressure of no more than 0.38 kgf/cm2;

T9 Bulldozer models

T9 with a rotary blade

  • T-9.01i- with Iveco F4GE0684F*D6 diesel engine, hemispherical blade and specific pressure of no more than 0,63 kgf/cm2;
  • T-9.01K – with Cummins QSB 6.7-C165 diesel engine, hemispherical waste dumpster and specific pressure of not more than 0,63 kgf/cm2;
  • T-9,01 km – with QSB 6,7-C165 diesel engine, direct dozer blade and specific pressure of not more than 0.37 kgf/cm2.

Within each of these modifications there are a few more varieties, differing by the presence or absence: slacker with different number of teeth, windage and traction losses. For example, the T-9.01Bbl-3 is a modification with a straight blade, reduced ground pressure, a winch and a three-tooth switch. OR: T-9.01KMB-3-This is a variation of the direct dump, reduced ground pressure and TCU modification.
