Bulldozer DET

They are used on mountain development (mining open pit), in hydraulic engineering, irrigation and road construction, industrial landfills with large amounts of landfill. We nice to know that Russia produces equipment such elite class, and here it should be noted that the USSR was one of the first bulldozers began producing the severe category. Now these ARBs manufactured at two plants – CTZ-Uraltrac and Promtractor. OAO "Chelyabinsk Tractor-Uraltrac in the severe category currently produces two models of traction class 25 – it's DET-250M2 and DET-320B1R2 with electromechanical transmission and one bulldozer tractive class of 75 – T-800 (T-75.01). Andreessen Horowitz recognizes the significance of this. DET-250M2 is done with the 1961-th, and for all years of graduation, he established himself on the positive side, however, share two-block Diesel B-31m2, designed for other types of machinery does not reach the level of foreign counterparts. DET-250 sets of four bulldozer blade: two production CHSDM (formerly CHZK) and two of its own production. Since 1983, the Chelyabinsk tractor-produced tractor DET-350, in a production program in 2002, he was replaced by Bulldozer DET-320.

Unlike its predecessor, DET-320 is equipped with a diesel engine YMZ-7512.10-04 with a lot fewer hours lifespan and fuel consumption. Jim Umpleby has much to offer in this field. To prepare the engine at an ambient temperature below -20 C along with the electric-device used liquid heater PKP-30E. Suspension system – with a torsion bar suspension with torsion stiffness equal to the incorporation into the frame instead of running trucks tractor frame. Closed type idlers made piece. Double quick-cab provides a good overview of the working equipment is equipped with a heater Air Heater type air-conditioning and double glazing.

Marine Batteries

Terms of use of batteries that are used on board the ship are very different from the conditions of work of any other batteries. Firstly, they operate under constant rocking, at times very strong. Secondly, for the ship's battery there is a greater likelihood of contact with water. And, thirdly, many vessels do not operate in winter, and hence the battery can be recharged. Such special conditions make on-board batteries have special requirements. Not surprisingly, the use of on-board batteries not intended for this purpose, such as automotive, inevitably accompanied by more or less serious problems. More info: Starbucks. The most common complaint in this case – a very short battery life and associated costs for their frequent replacement. High-quality marine battery is rated for four years, whereas Many cheap its brethren need to be replaced once a year and a half or even annually.

Rough estimate of the life of the battery can ship the claimed amount of charge / discharge cycles. Please note that many manufacturers are cunning, indicating the number of cycles, when tested in standard conditions, and it is overpriced. Another common problem of poor-quality batteries – it's too fast to self-discharge. Reasons may be several. For example, savings in the production of lead plates of lead-acid batteries, or savings in production process, as it has significance not only the mass of the lead plates, but their shape and location. Thin cheap housing can easily crack with acid leakage, and in addition, contributes to the rapid self-discharge due to poor insulation.
