Road pavement is known to wear out eventually and be renovated on a regular basis. Special road milling machines are used to improve roadways. They make it possible to level old road pavement, texture its surface, restore bonding properties, lower noise, remove the old surface layerwise or full-depth, rip up pavement for underground communications, hatches, as well as planarize concrete floor in manufacturing facilities. |

Having discussed the situation on the soil compactor market in the spring (“CTT” # 2/2010), we now proceed to the composition of layers of bituminous concrete surface. Here, we meet with an offer of technologies just as extensive as for soil machines. As seen from bitter and thorny experience in domestic road industry, the base soil and layers of road pavement containing chip, often turn out to be underpacked. The situation with laying bituminous concrete is even more difficult. Bituminous concrete is a more whimsical substance than soil or chip. Upon laying in the surface, after packing with compactors, bituminous concrete can turn out to be underpacked or unevenly and incorrectly packed (decompacted) or even overpacked, which leads to the destruction of its structure and, as a result, collapse. To a large extent this problem is related to the selection of compactor lines and their operating mode. And, of course, to the qualification of employees. |

Scissor lifts are used for lifting people and small weights up to the height of 20 m during elevated, erection, utility and building works.
They are divided into self-propelled and non-self-propelled. The lifting gear drive may be have both DC (battery unit) and AC (220V, 50Hz network) supply. |
| It is difficult to imagine industrial production that does not apply compressed air as a source of energy. Compressed air is produced by compressors providing air tools and various mechanisms with it. Compressed air is used to fill cylinders and containers as well as for cleaning, air flushing and pipeline pressure testing procedures. It is also used to carry out various technological operations in oil and gas industry and so on. |

To turn the procedure of housebreaking and demolition of buildings into a quick and efficient machine-operated process, we need modern construction machinery. It is essential to be accurate while removing buildings in confined urban conditions. Nowadays excavators with attached implements for demolition, including hydraulic shears have replaced demolition by a wrecking ball.
The shears consist of a frame to which cutters and breakers are attached (“jaws”). Depending on the construction they are powered by one or two hydraulic cylinders. As a rule, all the modifications of hydraulic shears contain a swinging mechanism, which allows to work without addition movement of building mechanisms and provides additional flexibility. High technical capability of hydraulic shears is provided by the ease of cutting blades replacement that are designed for primary demolition of constructions, secondary demolition and grinding, as well as metal cutting. |
| Excavators are an ideal option for applications in different industries – from general construction to forestry and agriculture. Their durable build provides good stability when soil profiling. They are prefect in forestry to build and maintain access roads, for reforestation, land-clearing and storing small-size timber, as well as road-building and log removal. |
| The article presents a survey of new models of pavement rollers in the Russian market over the last two years. The models’ construction features and technical specifications are given a detailed study. |
