Buldoser rykhlitelny unit det-400

Buldoser rykhlitelny the DET-400B1R2 unit on the basis of the industrial DET-400 tractor of a traction class 25 with the electromechanical transmission providing automatic control of speed depending on traction effort is intended for performance of digging and transport works on category I-IV soil, including on frozen and folding and rocky.

The bulldozer DET - 400 is created on the basis of the DET-320 tractor. On the DET-400 tractor for the first time in practice of domestic and foreign tractor construction electromechanical transmission with ventilno-inductor electrocars (LOOK) and an electronic control system is applied.

The modern double quick-detachable cabin is equipped with double-glazed windows thanks to which thermal and sound isolation of a workplace of the operator is significantly increased. The cabin is equipped with a heater "Zenith" and the conditioner - "RIO-3000".

Advantages of the bulldozer DET-400B1R2

Use of ventilno-inductor electrocars provides the following advantages of the bulldozer DET-400 in comparison with the DET-250M2 tractors and the DET-320 tractor:
Reliability surpasses reliability of cars with a direct current twice. The rotor of the induction engine has no winding and therefore an engine exit out of operation for the reasons connected with a rotor is practically excluded. In case of damage of the coil of a starter, it can be replaced without dismantle of the next coils that cannot be executed on electric motors of other type. Work in the conditions of the increased humidity is possible. Mass-dimensional indicators are lowered by 10 - 15% - the copper consumption is reduced by 500 kg. The power generator of transmission can be used as diesel-generator installation. The contactless control system of high reliability with the on-board computer and the graphic display in a cabin provides automatic control of operation of electromachines and knowledge of the operator of the current operating modes of electromechanical transmission. Test was shown that such electric drive provides almost ideal tyaguvy characteristic on all traction range since. the control system constantly supports loading of the engine on the nominal mode. -
