Drain filters
Filters installed on the tank drain
Filters are specially designed for the installation of the tank is used to drain the hydraulic lines.
Drain filters are installed to drain gidromagistralyah heat exchanger or directly to the tank top cover. Installation of the discharge filter on top of the tank, half-sunk in the working fluid, the most preferable because precluded discharge pipeline station, after a filter, you can install a compact, tightly consolidate the filter and ensure convenient and easy replacement of contaminated filtroelementa after removal of the upper lid filter. Flow filter assemblies must conform to at least double, triple nominal feed pumps to ensure an acceptable service life until replacement components.
Sizes foreign filters designed to operate at temperatures from -25 to +110 ° C in the summer varieties working fluid kinematic viscosity 30 mm2 / s (type HLP DIN 51524, an analogue of the domestic hydraulic oil MGE-46V for TU 38.001347-83).

The types of electric motors
The types of electric motors
Motors - indispensable component of the transport and handling of automated equipment: conveyors, automated warehouses, trucks, packaging machines and other warehouse equipment.
Typically, these units to choose their own equipment manufacturers, but increasingly it is so that buyers and owners of machines themselves can choose electric power units for the needs of your business depending, for example, on the specific circumstances of individual work sites.
In some cases the company completes the same type of electric motor technology at all of its plants and warehouses that by harmonizing procedures and spare parts to reduce the cost of maintenance. Sometimes motors opt for reasons of the low value.
Asynchronous electric
In warehousing and transport equipment handling the most widely used five types of electric motors:
- DC motors with permanent magnet excitation of;
- asynchronous alternating current motors. They are used in a continuous cycle of the equipment, for example, in conventional conveyor;
- servo (actuators). They work in cars, which must perform precise movements, and move to position the goods on a strictly defined places: in shtabelerah, automated storage systems;
- Linear asynchronous motors. Used in equipment, which is important especially high speed, for example, in sorting machines;
- Motor-rollers (or motor-drums), ie the leading tight rollers, which were inside small electric motors and gearboxes. Used to drive conveyor working periodically.
Previously, warehouse handling equipment loaded DC electric motor excitation of permanent magnets. At present, the machines and automatic completes asynchronous alternating current electric motors, the use of which is constantly expanding.

Winches with shpilevymi drums and sheaves kanatoveduschimi
Winches with shpilevymi drums and sheaves kanatoveduschimi
For shunting production and support operations at construction sites (for example, to pull from the place of discharge or heavy loads in the area serviced by a crane) to apply drum winch uncomfortable, because much of its length of rope needed Wind in several layers, which makes razmatyvanie rope and cause rejection it.
The most optimal shpilevoy drum, which is not navivaetsya rope, and it covers only a few races, and then go with the drum and placed next to the bay. Drum performed concave shape, providing job placement turns of the rope in the middle part of it. Tractive force developed by the forces of friction between the rope and the drum.
Winches with shpilevymi drums are used only as traction, as with the release sbegayuschego end of the rope force at the end of nabegayuschem no effect. To ensure work shpilevyh winches for lifting them establish kanatoveduschy pulleys, and sbegayuschy navivaetsya rope to a special drive-drum reels. Structures such a device called winches with kanatoveduschimi pulleys. Their appropriate use of a large crane with a lifting height (for example, in the construction of high-rise buildings) or as a special winches for specific operating conditions.
Winches kanatoveduschimi with pulleys and find application as a lifting device hanging scaffoldings used in the repair of facades. The difference between these structures is simply that sbegayuschy end of the rope not navivaetsya on reels, and hangs under load without ceasing to any position in height at a certain level, because when moving scaffoldings happens only on kanatoveduschim perematyvanie rope pulleys.

Now remember scheme fuelling diesel. The composition of the discharge system, virtually all diesel engines includes two fuel - the supply and fuel discharge. On the supply toplivoprovodu fed fuel to the engine of toplivoprovodu plum - the reverse flow from the tank to the engine.
Naturally, when the engine on the discharge pipeline in the fuel tank comes at a temperature much higher temperature fuel in the tank. Used fuel in the tank, it has a few of his heats.
In most of the fuel tanks and suction machines, fuel and discharge tubes are located in close proximity of each other. However, it is that they are far removed, and in this case as closely as possible to discharge tube toplivopriemniku that in Basair fuel temperature was higher than the temperature in the rest of the tank volume.
It happens that this will be enough to finalize the smooth operation of the diesel engine at low temperatures.

The heat of exhaust gases
The heat of exhaust gases
The last of the folk arts make sense to apply, perhaps only with a very strong frost in the Far North. This requires a slightly modified design of the exhaust system. In the fuel tank vvarivayut large diameter pipe, and through it to miss the exhaust muffler pipe. As a result of fuel in the tank is heated by hot exhaust gases from reaching the engine.
If you use this method heating fuel while the engine is running almost any frost is warm and freely supplied to the engine, not frozen, and the fuel filters. Nadeau only constantly and closely monitor air-tightness completed in a manner fuel tank and exhaust pipe. If the tightness is likely ignition fuel.
Please note that in the tube that runs through the fuel tank, skipping it is a release, not reception tube silencer. Gaze at the reception of the pipe is too hot, and with the slightest breach of tightness pipes and fuel tank ignition probability is great.
All these finalize construction desirable to hold the autumn, before the cold weather. They are tested in practice, and we can say with confidence: all this has been successful.

Attachment for loaders
Attachment for loaders
Recently, the demand is particularly heavy forklifts designed for handling in open squares internal business areas, in warehouses, sea and river ports, rail yards and product and terminals.
The main labor body cargo loaders are villas, which are set to producers serially produced loaders. However, in addition to the standard equipment Wheel loaders can be equipped with a variety of suspended equipment.
To date, for handling a large number of replacement hinged devices that extend the scope of the machine and improve the efficiency of its use. Their installation at the carriage loader takes a few minutes. The most common use of replacement equipment device for lateral displacement Wheel (positioner), with the top prizhimom hostage and hostage for barrels, rolls of paper bales, as well as various extensions villas, pushers goods, etc.
Correctly chosen handling devices make the usual knee loader flexible and versatile tool for the performance of warehouse operations, which increases the range of application of floor traffic.

At summer fuels - in the winter
Russian standards, three brands of diesel: "summer", "winter" and "Arctic". Even their names suggest that the brand of fuel is determined by the possibility of its use under certain ambient temperature. However, the requirements of standards, we have not always respected, and the weather presents surprises.
That's account drivers, tractors, excavators and bulldozers train drivers and other technology in all possible ways to combat the freezing of fuel to ensure "persistence" machines with the onset of cold weather.
Withdrawal from the provisions could serve as a preheater for diesel fuel. Such heaters are convenient, efficient, reliable and safe in operation. But most of our operators are unavailable because of their high cost, and sometimes the deficit.
Drivers are nothing remains as to remember the many people's means of ensuring efficiency in the engine strong frost.

Ranking operators leasing market is not only important for lessors themselves, but also for their clients - lessees, suppliers, as well as for indirect participants in leasing transactions - banks, insurance, investment companies.
Knowing the situation on the market, leasing allows all of them to determine who the most active in a particular market segment, what weight treaties in the overall value of their accounts at the leading operators, which vehicles and special equipment are most popular consumer leasing services.
In this connection, a survey of Russian leasing market, which uchastvovalo153 leasing companies. For the year, and they reached new contracts funded by an amount equivalent to more than $ 17 billion As a result, the volume of leasing business in the country has doubled compared to 2005. This is the highest rate in the history of Russian leasing.
The value of the lessor's lease portfolio has been identified on the basis of figure, which takes into account the European Federation of National Associations of leasing companies (LEASEUROPE) - "outstandings". This figure takes into account the amount of the payments under existing treaties lease, lessees who have yet to pay leasing companies. This amount to the beginning of 2007 21750 million U.S., including VAT.
Given the market structure avtolizingovyh services were compiled ratings (renkingi) lessors, on the basis of 2006. Of the 153 lessors 137, or nearly 92% of lessors, in varying degrees, conducted operations from motor vehicles. That is virtually all leasing companies, with the exception of a dozen specialized, avtolizingom involved.

Problems start-up of diesel engines
The main advantage of diesel engines, compared with petrol is relatively low fuel consumption. Therefore, in recent years in connection with the Kyoto agreement and Samoobyazatelstva European Automobile Manufacturers of S02 reduce local emissions by 25% to reduce the greenhouse effect planet diesel engines are becoming more common.
Their developers have to face the challenges associated with the removal of a number of shortcomings. One of the main drawbacks of diesel engines, compared with petrol launchers are worsening the quality of operation and the complications at low temperatures.
To improve the quality of diesel engines, launchers used electric candles bars, candles heating, elektrofakelnye heaters, predpuskovye and fuel heaters.
