Road-building equipment

When calculating the energy balance determines the power going to the drive lawnmower with a working body ploskovraschatelnym cutter on the capture of 1 m, with a height of 14-16 cm herbage, this power is equal to about 4.4 kW.

In the finger-type cutter is cut by moving the active (moving) blade relative to a passive (stationary). To facilitate the process of cutting edges of active and passive blades have a certain angle to each other to achieve a slip. Moving lets you transfer the motion of the friction force in a plane perpendicular to the direction of the cut, which reduces friction and facilitates the penetration of the knife cut into the thickness of the material.

Machines for road surface marking. Dividing lines and stripes on the road surface is applied with special marking machines, which can also be used to color the way the situation, road signs and buildings. Marking machines are classified by the method of spray painting to the type of material used and the type of chassis.

Paints and thermoplastic materials which are widely known for marking pavement, causing beskompressornym, pneumatic, kinetic and gravitational methods. The use of thermoplastic pavement markings for increases (compared to paint) wear lines. The layout of the paint to update 3 times a year, and thermoplastic - after 2-3 years of operation.

We recommend to look

• Generator ESS-81-4
  Generator ESS-81-4 provides 20 kW of electricity consumers. The drive of the generator from the motor shaft base unit via PTO, driveshaft, intermediate support and the V-belt transmission. The compressor provides the blasting and spray charts. Elektrovibrotrambovka designed to seal freshly placed mass with a width of the repair area is less than 500 mm. Elektrovibrokatok used to seal freshly placed mixture to [...]
• Economical use of reagents
  Economical use of reagents provided not only by adjusting the density of the process, but also the proper distribution of it on the pavement area. It is known that the necessary mix of snow with the reagent is achieved where there is vehicular traffic. In connection with this reagent is distributed only in the lane, which is about 70% of the entire area of the roadway of the streets. Absolutely [...]
• The device of special vehicles for road maintenance and disposal of household waste
  The special cars for the summer maintenance of urban roads include watering, washing, sweepers, as well as machines for mechanized cleaning of wells and storm sewer mains. Watering-washing machines. They are used for cleaning and watering of roads with asphalt and cement-concrete surfaces and gutter sections, as well as to sweep dust, dirt and debris, they can be used [...]
• The device of special vehicles for road repair and maintenance of road conditions
  Special vehicles for repair of urban roads - a machine whose purpose, transportation and distribution of bitumen (at surface), the destruction of hard surfaces and digging wells, heating and leveling asphalt coating, crack sealing, etc. Machines for destruction of solid surfaces. When carrying out repairs of city streets, thoroughfares and squares to the partial destruction of their coatings, and in [...]
• Management of special equipment
  All management of special equipment is located in the driver's cab. The torque from the motor base unit is transmitted through the PTO, protective sleeve, hand-outs and conical gears on the drive shaft and the shaft conveyor screw feeder, as well as to drive the main brush. The second (upper) power takeoff shaft is used to drive the oil pump gear. Hydraulic drive car is [...]
