Bulldozer CHETRA T9 technical characteristics

The use of modern methods of designing equipment, the use, along with domestic ones, of units from well-known world brands, modern production and proper quality control make it possible to produce construction machines in Russia that can adequately compete with analogues of companies popular all over the world. Products under the Chetra brand have managed to earn recognition and take their place at a variety of construction sites, developments, and industry.

Engine YaMZ-236 NB-2

The six-cylinder V-shaped (camber angle 90°) four-stroke diesel engine with turbocharging and air-to-air charge air cooler, liquid cooling YaMZ-236 NB-2 of the Yaroslavl Motor Plant has the following characteristics.

Leasing of road construction machinery and equipment

Currently, more and more companies are using such a financial instrument as leasing, updating and expanding their technical base.

Leasing as a type of contractual obligation appeared in Belarus relatively recently - in the early 90s. last century. This is one of the forms of lending for the purchase of goods.

Leasing is a more accessible type of financing than a classic bank loan. With its help, private and public enterprises can purchase modern equipment and special equipment, introduce new technologies, increase their efficiency and competitiveness. This service is even more attractive in the current economic conditions.

The traction force depends on the weight of the tractor and the traction force.

STEERING AND BRAKING CONTROL

Side clutches are multi-plate clutches that are hydraulically actuated. Stopping brakes are multi-disc clutches that are permanently closed by spring force. Onboard clutches and brakes are cooled by oil under pressure and do not require adjustment during their entire service life.

FINAL TRANSMISSION

The final drive is two-stage, the 1st stage is external gears, the 2nd stage is planetary according to the “to +1” scheme (with a stopped ring gear). To facilitate replacement in the field, the drive sprocket is made of five sectors that are secured with bolts.

CHASSIS

Suspension: three-point semi-rigid with a remote swing axis of the bogies provides high traction properties, reduced shock loads on the chassis system, and improved working conditions. Support, support rollers and idler wheels with one-time lubrication for the entire service life with self-clamping “double cone” seals.

Tracks: Prefabricated with a single grouser and seal to retain liquid lubricant in the joint. Track tension is easily adjusted with a grease gun.

HYDRAULIC SYSTEM

Separate-unit hydraulic system:

• gear pump S1A5070, capacity 120 l/min at 1700 engine rpm
• four-section distributor, consisting of one valve and three spool sections
• maximum response pressure of the safety valve 20 MPa (200 kgf/cm2)
• hydraulic tank capacity (welded tank, adapted for mechanical cleaning of internal surfaces) 85 l

Device

CHETRA T-9 has a semi-rigid 3-point suspension with a remote bogie swing axis, which provides increased traction and grip properties, improves working conditions and minimizes shock loads on the chassis system. The bulldozer's idler wheels and support rollers have double cone seals and are lubricated, requiring no replacement.

The tracks of this model are prefabricated. They are equipped with seals and lugs, and track tension is adjusted using a grease gun.

The bulldozer's gearbox is of the planetary type and shifts under pressure. It is structurally combined into a single unit with a main gear and a matching gearbox. These elements are installed in the rear axle bore.

CHETRA T-9 provides comfortable working conditions for the operator. The bulldozer is equipped with a single-seat cabin with double glazing, which features good visibility of work areas and equipment, regardless of working conditions. The cabin also features a dependent heater, a ventilation system, noise-absorbing upholstery and vibration-proof seats. Optionally, CHETRA T-9 is equipped with air conditioning and an additional heater.

The bulldozer controls are installed in accordance with ergonomic requirements and are easily accessible. The operation of the diesel engine is controlled by a pedal, and gear shifting and the choice of direction of movement occurs through the movement of the lever. It is quite convenient to operate the bulldozer from the operator’s chair, which allows you to carry out work without overwork.

The main differences of the CHETRA T-9 model are:

1. additional Fleetquard fuel filters with fuel heating and water separation functions;
2. air-to-air coolers (for modifications with a German engine);
3. monolithic aluminum radiators made in Germany;
4. modular design of systems and components;
5. modern heaters;
6. mobility;
7. 3-point semi-rigid suspension.

CHETRA T-9 is far from a cheap pleasure. A new bulldozer of this model will cost 4-4.5 million rubles. Used versions from 2013-2014 can be purchased for 3-3.6 million rubles.

Analogs

Analogs of CHETRA T-9 include KOMATSU D63E-12 and CATERPILLAR D6T. However, these bulldozers are an order of magnitude higher than the Russian model (about 1.5-2 times). Models SHANTUI SD16 and B10M.08 are comparable in price and power characteristics to CHETRA T-9.

Video

For these versions of the bulldozer, most of the parameters are similar. Climatic modifications of CHETRA T-9 are “T” and “UHL” according to GOST 15150. With a full load, the equipment can be used at temperatures from -50 to +35 degrees. At higher temperatures, it is recommended to limit the load on the bulldozer to a level that ensures normal engine operation. At temperatures below -50 degrees, you should also reduce the load on equipment by maintaining it in working condition by moving without load and turning on the hydraulic system even during breaks.
