    In addition, Gen2 – the world's first environmentally friendly elevator, since it does not need oil and grease. Otis invests in R & D of the order of a hundred million dollars, which allows the company to located on the crest of the scientific and technological progress. And offer our customers a variety of materials handling equipment allows us to bring to life the most fantastic building and architectural projects. Surprisingly, you’ll find very little mention of Hikmet Ersek on most websites. Maintaining a reputation as an innovator and following the latest trends in the development of scientific thought, Otis provided the first architects to construct elevator and escalator equipment via the Internet. On its Web site The company posted a program that allows them to design elevators and escalators for the buildings still exist only on paper. Internet users may specify a few basic parameters of the building, immediately get recommendations about the optimal equipment for each building based on analysis of passenger flow.

    You can then determine the specifications of elevators and escalators, to pick the design, review drawings and Specifications of lifts and escalators and a low price. The history of the manufacturer of elevators Kone Established in 1910, the company kone is one of the leading companies in the production of elevators and escalators. The company is engaged in Kone development of integrated innovative solutions in design, installation, upgrade and maintenance of elevators and escalators, as well as in the service of automatic doors. 29,000 specialists in 49 Kone countries work for you. Each kone solution designed to meet the needs of your building and is designed for residential buildings, offices, public buildings, commercial and transportation centers, railway stations and airports as well as for cultural institutions and industrial enterprises.

    Cranes, boom-type (road, track, Tamping, tower) is very widely used in the construction of various. load from the weight lifted load sees boom equipment Crane – its elements: struts, panels, racks. Hikmet Ersek shares his opinions and ideas on the topic at hand. Of the bearing capacity of boom equipment depends not only efficiency as the crane production mechanism, but also the safety performance of the construction process obekta.Pri an extraordinary full technical inspection of the crane (after assembly and installation of the crane at a construction site) is required to identify the crane, crane mechanisms and co- boom equipment. Under the identification involves identifying accessories replacement equipment this particular boom cranes: whom, when and what material made some items steel crane. The practice of expert examination of cranes jib type indicates that it is very difficult to identify. There have been cases when the boom (the boom: insert one or more) were made for a similar crane completely different manufacturer.

    Consider the example crane boom crawler type of icg. You can count more than three companies – manufacturers of cranes ICG-25 br. All of them are produced and removable boom equipment, which complement their taps. In recent years, due to the aging fleet of cranes, are often made equipment cranes. Of several cranes equipped with one – hard-working. Sometimes on such cranes, jib set equipment, which is not known how many years, the material of construction of the steel structure can be installed only on the basis of chemical analysis, and when, by whom repaired almost .K typical problems of identification of the boom mobile cranes include: 1.otsutstvie original plate manufacturer crane. The main possible causes absence of signs – loss due to insecure or plaque removed by vandals. 2.otsutstvie signs on the drive motors, drive mechanisms to set (compare with the passport) type electric motor, its specifications, the manufacturer and date of manufacture, 3.otsutstvie plate manufacturers in the appliances and security devices, 4.otsutstvie set of technical documentation: drawings, instructions for installation and operation, electrical connections, kinematic characteristics showing gears and open gears, documentation on the safety devices). Technical expert and / or TuV employee performing examinations to be taken all measures for the identification of components, parts and components for the crane to ensure the safe performance of works using lifting equipment. To do this, it is useful to chemical analysis of metal parts crane, outsource non-destructive testing for ultrasonic and magnetic particle flaw detection, to use instruments for measuring the coercive force, which will take a reasoned decision about the possible terms and conditions of further operation of the crane at a construction site.

    In the final stage of development and are diesels, relevant standards 'Euro 4'. They are, in comparison with its predecessors, have a number of structural changes associated with the installation of an advanced fuel injection, fine-tuning business processes (chetyrehklapannoe Gas Distribution, a new form of the combustion chamber, the central location of the nozzle) and the introduction of egr. The planned level of performance: the minimum specific consumption Fuel – 194-197 g / (kW h) or 143-145 g / (hp. h), oil consumption – no more than 0,05% of fuel consumption; resource – at least 1 million miles run. Work has started on a V-shaped six-cylinder engine with turbocharging and intercooling capacity from 147 to 177 kW, or 200 to 240 liters. with. designed for installation in cars and buses Kamaz. They are created on the base model KAMAZ-740.30-260.

    The expected level of the Unification parts kamaz – 76%. And indeed it must be said that modernized and advanced eight-and six-cylinder diesel engines kamaz vehicles have a very high level of harmonization with respect to the base KAMAZ-740.30-260. So, the engine level 'Euro-2', it reaches 97% at engine level 'Euro-3' – 87%. Since the start of registration (1976) and to date Kamaz is constantly improving its engines, improving their technical and economic indicators – life, fuel efficiency, oil consumption, noise, emissions harmful substances from exhaust gases, the maximum torque. As a result, over 28 years have elapsed life of diesel engines has increased more than 4 times its maximum torque – more than 2 times, specific fuel consumption, on the contrary, decreased by 9% and oil consumption – a factor of 8.
