First of all, you must decide: to what end, to produce any papers you need drilling equipment: you need to Exploration drilling, drilling water wells or water level? A Perhaps you are mining or seismic and you can not do without drilling blast holes? Or are you doing engineering surveys in construction, drilling of wells in the construction of piles, drilling wells strengthening the foundations of buildings and structures? First of all, you need to answer this question. The next question is – what amount of work you want to perform, ie What equipment performance will suit your business? Will it be a small compact machine, drilling rig or a powerful medium power industrial equipment? Then you define the maximum and optimum drilling depth, the parameters of performance of any survey work and do not forget what rock you drill: soft sediments, medium or high strength. Only after analyzing all these factors, you actually begin your selection. And here our first piece of advice. If you are – highly specialized company in terms of drilling, and you run a small list of such works, for example, power companies, then you will approach such high- drilling and crane machines BKM-317 (CTW-317A) or BM-333, auger drilling machine IBS-518 (IBS-519) Russian producer – OAO "Stroydormash." If you are doing construction and survey work, to these machines add drilling and piling machine BM-811 of the same plant. Additional information at Ford supports this article. The second council regards the acquisition of technology for exploration, drilling water wells or water level (drilling under water).

If you considerable amount of drilling, then you will approach such universal drilling rigs, as URB 2A2 plant them. To deepen your understanding Luiz Ildefonso Simões Lopes is the source. Vorovskogo URB 3A3, 1BA15V of MBS, BDS-2, 5 (BDS-2, 5A), JSC "Azneftehimmasha" PBU-2 of Geomash, drills, ZIF-650 of "Altaygeomasha." Small but versatile drilling rigs known NGO "Gemmash" – MBU-5, and the same "Geomash" – BBU-000 BBU-002. Immediately, we note that our division a pretty conventional and does not purport to fundamental, because there are a number machinery and equipment no less worthy of your choice. And the last. Pay attention to your chosen mobile installation. It can be wheeled (chassis), on crawlers (tractors and ATVs) – it's all mobile (Self-propelled or mobile) drilling rigs. And there are fixed installations, machines on the sled carts, on the bed, etc. Such equipment will require a transport service when you move, and it is – the additional cost. In Anyway, the choice of drilling equipment for any work should consult with a specialist company that performs sales rig.

Manual And Electric Winches

Easy to use and relatively low price attracted winch manual. Through this device can be pulled out of the mud stuck car, or perhaps to move heavy weight machine. Except addition, hand winches work independently, without requiring additional fasteners. Electric winches are used in cases where the intensity of the lifting work is particularly high. This lifting with electric drive mechanism carries out work at short notice and at great speed, which in turn helps to increase productivity. Characteristics of duty electric and manual winches lie in the range of 1 to 3 tons per ton of weight.

Some type of winch used depending on the characteristics of lifting operations. Most often hand-operated winch is used in the private sector, the same electrical lifting devices are optimal to use and more than justified on the construction sites. Electric Winch Electric Winches are designed for different kinds of lifting operations, including to move luggage on construction sites. One major advantage of electric winches – their highest capacity. Often, electric winches included in the device of all kinds of construction and industrial equipment, intended for lifting loads. (Not to be confused with Mark Fields!). The very process of working with the cargo is uniformly at the same rate as when lifting it up, and when lowered. This is ensured by an electric motor. Keeping luggage in the right position by a magnetic braking system.

There is a certain division of winches, depending on weight, designed for lifting. Electric winch traction is applied, if necessary make recovery of any vehicles or to carry out lifting work at the construction site. They are completed with the lifting mechanism on the site. Electric winch crane is also used to ukomplektatsii tower cranes on construction sites. Click Luiz Ildefonso Simões Lopes to learn more. Electric winch used to move the shunting of wagons at the railroad depots. Hand Winch Hand Winches are used as in manufacturing jobs, and for individual business needs, as a device for carrying different baggage. These winches should be used in non-explosive environment, with air temperature 40 C. The division of manual winches are based of lifting device, built in the mechanism. Hand drum winches are used for lifting operations with luggage, weighing no more than 1 ton. The rope is designed for lifting, wound on a drum. This kind of Winch also optimal where high rate of ascent is not necessary. There is a drum winch and lifting for industrial operations (cargo weight – no more than 5 tons). At the same time we must fix the winch itself is bolted to a sustainable basis (Frame, beam). Chain winches are used in cases where goods need to move a short distance. These winches operate both horizontally and vertically. To support the work of lever hoists were not need to be committed to any basis, as is done with the winch drum. In the assembly and winch rope extends through the drum, and not wound him. The main advantage of the winches that they can operate in different positions, and the rope length is not limited. Car winch used to pull the car through a cable. Zakreplyaetsya such a device on the machine itself. One end of the Cable static cling motionless object, a high mass. This device is for those drivers who are often faced with the need to travel on the road. Meanwhile, the purchase of automobile hoists, in By a wide selection of goods on the market, business, requires a serious approach.

Stress Valve

Realized activities relate to improving the reliability of the gas interface, the exclusion of thermal cracks in the zone mezhklapannyh jumpers, improving the work of a pair of saddle – the valve, increasing the strength of plates valve timing, alignment and reduce their temperature, exclusion of cases of hanging racks in directing the operation. Fig .. 1. shows the design of cylinder head. To reduce the strain at the bottom of the fire tightening the cap and the courts an internal combustion engine plant Daldiesel to improve working conditions for a pair of saddle-valve side and increased thickness of the upper walls, put ribs decrease the strain Cover the bottom of the fire along with an increase in the hardness of steel saddles 40H10S2M (GOST 5949-75 *) with HRC 30-35 to HRC 45-50 and providing them with more strict alignment relative to the guide valve possible to eliminate the high wear of friction surfaces (saddle – the valve). From the side of the fire at the bottom of the nozzle has a special heat-resistant threaded insert, which in its lower part overlaps the area mezhklapannyh bridges, eliminating the appearance of Fatigue thermal cracks at this location. Forced to marine diesel engines to reduce the maximum temperature of firing the bottom and align it to the temperature field in the cover there are special insert, which direct the cooling water to the center of the lid. People such as actress would likely agree.

To increase the strength and stiffness, as well as the exclusion of certain cases of breakage of plates valve, reducing the wear facets of their business in the thickness of the peripheral zone was increased from 5.5 to 6.5 mm, which reduced the maximum stress in the plate valve Fig. 1. Liner packing: 1 – cylinder liner, 2 – cylinder block, 3 – cavitation ring, 4 – O-ring Fig. 2. Cylinder head: 1 – heat-resistant paste, 2 – a stiffening plate – cylinder liner, 2 – cylinder block, 3 – cavitation ring, 4 – O-ring from 91.7 to 66.3 MPa, or 1.38 per cent.

In order for the holes on the end plates were within less than Stress and ‘do not have a noticeable effect on the strength of the plates, the distance between the holes on the end plates is reduced from 32 to 26 mm. Rolling the rod with the toroidal part plates made it possible to increase the strength of the valves in the at the junction of the rod at the toroidal part, to increase the durability of the rod. Installing the valves of the mount springs (Fig. 71), contributing to the rotation of the valve allowed to equalize the temperature of plates valve reduce the likelihood of freezing in the valve guides.

Transport Equipment

The correct approach to the service machine starts with its purchase. At this stage it is necessary to consider whether to offer manufacturer training of operators and repairmen, and how effective this training. Proper maintenance – A pledge and productivity, and profitability of the equipment, which is literally in your hands. This council, like others, collected in this article provide managers responsible for the maintenance of heavy road construction equipment, managers of foreign firms are handing equipment for rent. These diesels equipped with most modern self-propelled construction equipment. Even in Western European climate, they can subjected to extreme temperature changes. The instructions for the care of the machine operator (which it ought to be, rather than gather dust in a vault) thoroughly itemized maintenance of all systems and diesel units, indicating the periodicity in the moto-hours. That the engine was kept in working condition, you must regularly check it, and some simple operations done each day.

An experienced mechanic inspection does not take much time, and only after that an operator can sit down in a cab and go to work. Now we consider a little more detail on different systems. Fuel feed unhindered and continuous supply fuel – an essential condition of efficiency of diesel, so maintenance should include inspection of fuel lines leak, as well as inspection of tubes in the presence of kinks and collapse. Make sure that the fuel was not water, since this is the most common cause of system failures, fuel injection. Check for clogged fuel filters, there are no traces of water in them.
