If you look in the BES, we will find is about the definition – "concrete pump, construction machine for pumping concrete to the site of her laying on the Delivery line. By their construction, and B. one-two-cylinder, by the nature of the drive – crank and hydraulic. B. In both types of piston draws in a concrete mix from the hopper pump with closed discharge valve (valve) and open the suction and reverse motion pushes the mixture into the Delivery line. B.
with hydraulically driven, compared with a crank, are long stroke in the working cylinder and a constant piston speed, which ensures uniform movement of concrete mix, reduced resistance to motion in a mixture of Delivery line and motor power. Jeff Flake has much to offer in this field. Produced in the USSR BA capacity of 5, 10 and 40 m3 / h, feeding the concrete mix vertically to 40 m horizontally and up to 300 m. The equipment includes B. Delivery line of individual tubes with quick couplings. "largest concrete pump in the world did the German company Putzmeister. It was a giant pyatisektsionny 63Z Ktorov mounted on the chassis of the Canadian firm and TOR can submit a solution to the height of 63 m.
A specially designed vehicle with wheel 14h6 refers to the range of 8 to SUPER Class American classification of trucks. The first four are supporting the bridge, the last three – the driving. Chassis length – 16.32 m. The distance between the axles – 2032 mm. For other opinions and approaches, find out what Primerica Shareholders has to say. Massa special vehicles – 50 m. All the wheels "shod" in the usual rubber. It is worth adding that concrete 63Z also can be mounted on a 7-axle chassis MASK series MR. The most common are fixed pumps are designed to receive a freshly prepared concrete mix of specialized tools and betonotransportnyh filing of its horizontal and vertical directions to the place of installation in the construction of buildings and sooruzheniyiz monolithic concrete and reinforced concrete.

CA cylinder stability-2 is designed to determine the stability of the indicator fluid. CA cylinder stability-2 is a cup with a handle, which at mid-height of a challenge to the cork. He designed to determine the stability of the mud. Stability index is defined as the drilling mud density difference between the upper and lower half of the sample solution, otstoennoy during the day in cylinder 200 mm high. The instrument used in the oil fields.
It is a cylinder with a drainage tube midway. You may find Dennis Lockhart to be a useful source of information. If it pour the wash solution containing a certain amount of coarse-grained faction and withstand a certain time – then over time there is subsidence of the solid phase and an increase in specific gravity of solution at the bottom of the cylinder. Merging separate solution from the top and bottom of the CA-2 and defining the ratio of their specific gravity – we can estimate the ability of remote wash solution prior to drilling, and if necessary increase to the desired level by introducing an additional quantity of bentonite or reagents enhance the ability to bypass the solution. Design and operation: cylinder stability CA-2 is a cup with a handle, which at mid-height of a challenge to the cork. Determination of stability is carried out by measuring the difference in density between the upper and lower parts of the sample solution. To do this, the side opening of the cylinder cap must be closed, and the stability of the cylinder set on a flat surface. Fill the CA-2 solution to the top and leave it over night.
After holding the upper part of his solution poured through the hole. Further measured the density of the upper and lower part of the solution took place. Stability index is defined as difference between the upper and lower halves of the sample solution stand for a day. Storage and transportation: long-term storage of all the metal parts of the cylinder must be thoroughly cleaned and subjected to conservation rustproof lubricant K-17, GOST 10377-78. Transportation of the cylinder must be carried by any mode of transport in conditions which exclude the possibility of direct exposure to precipitation and corrosion. Manufacturer's Warranty: The warranty period of the cylinder 2-CA-18 months from the date of commissioning, under the conditions of its storage and use, but not more than 24 months from the date of manufacture. Specifications: Capacity of 700 5 ml. The delivery cylinder stability CA-2 includes: – a cylinder – the instruction manual.
Manitou Forklifts for various industries throughout his history of Manitou successfully acted on the global market of loading and construction equipment as an active producer, and not going to stop there, and only gaining momentum. MANITOU Group of companies strive to create new and enhanced engineering models for use in various fields, such as construction, Agriculture and forestry industry is constantly expanding and adding equipment model Manitou. Adapt the technique produced to meet the needs and characteristics of the market. MANITOU in the construction industry The idea of using forklift on uneven surfaces, such as construction sites or in agricultural production owned by Frenchman Marcel Brod (Marcel Braud). In 1957 he equips MsCormick tractor hydraulic control and located behind the mast. The result of such "experiments" – a vehicle that has received the name of Manitou (from the French manie tout – transports all"). In 1981, there Manitou all-terrain forklift c telescopic mast and forks to capture the pallet, called Maniscopic.
Later, the company began producing trucks and mounted. Today, Manitou is the largest global producer of all-terrain forklift c European market share 57% (share of the world market – 35%). Building and construction work in modern construction are paramount pace of construction of buildings. So far, in Russia a large group of works did not have sufficient technical support. It is such work as: Installation and mounting of columns, beams, trusses. Hanging the front frame structures: panels, windows, etc. Delivery inside the premises of technological equipment.
Industrial ventilation should fulfill two main objectives: to ensure optimal ventilation in industrial premises, and, accordingly, to bring the climate given values. In addition, modern industrial ventilation provides training and technical process to ensure the air with the required characteristics that, for certain types of production, is very important. In addition, ventilation "Responsible" for prompt and effective removal of all air pollution and disposal of superheated air. That is why, depending on the type of production and process technology, the device manufacturing ventilation must be approached individually in each case. Supply and exhaust ventilation Supply and exhaust ventilation, because its main purpose – to ensure ventilation in rooms, perfect for use it for, it would seem, is not entirely typical of the role. Namely – to save energy needed for heating.
Similar installations were fairly widespread, because of their energy efficiency, and are balanced ventilation with heat recovery. The principle of the heat exchanger is very simple. The fact that the air being removed from the room is heated to at least room temperature. Supply and exhaust ventilation, provides both outflow and inflow of fresh air, which may not be very comfortable in their temperature characteristics, for the people. That is why the equipment supply and exhaust ventilation heat recovery, can expand the range of tasks: in addition to providing simultaneous heating air to supply air through the exhaust heat.
That very effectively, and allows no only significantly save on heating, but also more quickly recoup all the costs that are necessary for effective device ventilation. Forced ventilation at home and at work Forced ventilation can get into buildings and premises for various purposes, and be local or log in to the general exchange ventilation. Forced ventilation can perform a variety of tasks, providing how to create a favorable microclimate in the premises as a whole, and performing special tasks, providing a local ventilation. Forced ventilation, the type of device is divided into natural and artificial. Natural forced ventilation does not require mechanical stirring, air flow is due to the laws of physics, through natural openings or slits, or through specially arranged holes. Supply ventilation with a mechanical drive is equipped in buildings and premises in the event that provide optimum air circulation in a natural way possible. In addition, a number of requirements in the process production facilities, buildings or other purposes, requires the mandatory unit effective mechanical ventilation. And in this case, the only industrial-grade ventilation systems could create enabling environment for both people and production.
But in one of the branches of modern industry has been particularly active presence felt MANITOU – we are talking about forestry and wood industry. Very stringent harvesting, clear terms problems of transportation and loading of long materials, logs, boards very narrow range of technical tools that can be used in the timber industry. And then the company MANITOU, as in many other sectors of activity where involved hoisting machinery, rose to the occasion. One of the latest trucks, created by designers MANITOU – telescopic all terrain for long loads TMT 2520 SR 4W. Multifunction wheel lineup MANITRANSIT can unload and load trucks with long timbers, trees, beams on one side. Long bypass valve which raise the load more than three meters when capacity of two and a half tons copes with industrial handling of timber and forest products. Widely separated forks can firmly hold the beams and carry out complex loading operations.
Quite a unique machine, lifting up to eight tons to a height of four and a half feet – JUMBO JDQ 40-80 can carry extremely long and heavy logs. Special platform and double fork reduce the load on the pneumatic part of the machine, thereby creating optimum conditions for the transport board in wood-processing enterprises. Mast-Series MSI has also been actively involved in loading and unloading of the timber industry. These diesel cars terrain can lift up to five tons and have a mast lift, which allows to lift loads up to a height of 6 meters. This feature is used during storage of logs and stacks of plates on the ground harvesting. In addition to heavy telescopic mast forklifts and timber work in the compact all-wheel-Series trucks and MH MC. This is a technique used directly on the harvesting sites, allowing the use of not only the fork, but lesozahvaty.
Perfect balancing machines You can move entire trees, deploy them, simplifying the initial processing. With a lifting height of up to seven meters capacity machines Series MC – to 7 tons. In addition, a widely used class loaders CD. At Small capacity of up to three and a half tons, stable and comfortable diesel loaders perform a variety of CD 15-25 works on the transport of already-treated timber and packing cars with wood. The presence of a stabilizing hydraulic system, can significantly increase the stability of these machines and make them indispensable for transport of wood. Prepared according to the company Manitou and CVH.
