floor covering special materials with a large thickness or high heat (thick slab of marble or granite, etc.) In all these cases it is necessary to increase the capacity of the system, as well as to conduct heat engineering calculation. Special mention should be on the premises with a wooden floors or parquet. Due to the low thermal conductivity of wood at a standard power density of "warm floor" temperature at the surface of the floor will be noticeably lower than desired. At the same time under a wooden cover in the space between the beams, due to poor heat transfer surface temperature of the cable will increase. Thus, the power cable will be mainly spent on heating the wood, which is extremely undesirable from the point in maintaining its moisture. Some companies offer for rooms with wooden floors and sections of heating cable with a specific power of 10 W / m Of course, the cable will not heat too much, but heating in such systems is practically unnoticeable. On the use of "warm floor" as the main heating system in such premises, however. To avoid misunderstandings, as well as the increased fire risk, we does not recommend the use of "warm floor" in their classical performance in rooms with wooden floors. Hyperfine "warm floor" Purpose: When the device "warm floor" during the repair or reconstruction is often not opportunities to increase the thickness of the floor, even at 3 cm (the minimum thickness of screed for laying cable).

May have a width of 3.3 mm to 5 thousand thousand mm, as prism drawing of 4 cubic meters to 19.6 cu. m hemispherical and hemispherical increased blade (the indices E, E1). Features: Used for works that require high performance. Provide production of the work of stripping to the development of hardened clay, sandy limestone develop, detrital grunt.Sovmeschayut high ability to direct the blade into the ground and the introduction of the spherical blade to move large volumes of material at the expense of short side sections set at an angle to the central section. That provides greater capacity. A geometric shape allows it to rapidly fill.
System is fitted gidroperekosa. Have higher productivity in the development of soil compared to the straight blade. Blade Enclosure is designed as a closed-circuit loop, which increases its durability and reliability, especially when working in a twisted position of the blade. Spherical blade (index 'K' (carbon)) Bulldozing equipment with spherical blade (Subscript 'R' (carbon)) easily moves large volumes of light and friable mass with a small proportion of coal, snow, peat, etc. Features: Spherical blade is particularly effective for moving large volumes of light soils in long distances.
It consists of three sections: a central and two lateral. The latter are located at an angle in terms of up to 25 to the central section. The curved shape of the blade in terms of ground displacement to provide mid-blade, while ensuring minimal loss of material transportation. Straight Blade (index B) Straight Blade makes the work of opening up the development of hardened clay, sandy limestone develops, detrital soil. Features: Bulldozing equipment with a straight blade is a versatile operating equipment for the development and movement of soils of different types and grading. Blade Enclosure made in the form of a closed circuit loop, which increases its durability and reliability, especially when working in a twisted position of the blade. Rotary blade (index 'D') with dozer equipment angledozers develop and move the soil used in the transverse transport of soil to backfill excavations and trenches, erecting mounds and clearing the area of snow, debris, vegetation. Beading road base cloth, clearing the pavement, including in winter conditions, carry out planning work cut terraces on the hillsides, ditches. Features: Rotary blade can be rotated around the hinge in the plane of the frame in both side. The shape of a straight blade without lateral cheeks, elongated in width and shorter in height. In addition to setting the blade in the forward position, further work could produce a blade mounted at an angle relative to longitudinal axis of the tractor: turn right at an angle of 25 , turn left at an angle of 25 . Skewed blade by screw braces. The right choice for the bulldozer blade is the main condition for achieving maximum possible performance. To select the blade should evaluate the soil, the ability to dig and traction and performance characteristics of a bulldozer. Features of digging the soil are determined by the ratio of maximum traction to the length of the bulldozer blade knife. The higher the number, the stronger soils can develop a bulldozer.
