Road marking machine for road marking: types and description

The First attempt to use road markings recorded in England (1921). This system is still in use today, ensuring the safety of pedestrians and the orderly movement of vehicles. To accelerate and facilitate the process of drawing signs and lines allows marking machine. Next, consider the types of these devices and the characteristics of their work.

Classification

This type of road equipment belongs to special type equipment, is divided into classes, depending on the technology used:

1. Marking machines, those lines and characters by airless or atmospheric way using paint.
2. Hardware working using thermoplastic.
3. Units with airless design, where the working element performs a cold plastic spray.
4. The Marker with the extruder, a thermal spray polymer.

Type of movement technique is divided into self-propelled, hand-held and mounted. Mechanical method involves the use of light and easy to manoeuvre and marking machines. Despite the small performance, such modifications are perfectly suited for difficult areas where dimensional units are not able to call.

Marking Paint on asphalt

The Coloring material is divided into two main categories – paint and thermoplastic coating. It should be noted that the airless method makes it possible to economize marking components regardless of their viscosity. Thus dealt the silhouettes have a high resistance to wear and deformation, along with the excellent stain-resistant properties.

Features marking machines largely attributable to the method of spraying the coloring composition and its quality indicators. The main elements of equipment from aerial spraying include:

• Air Compressor.
• Spraying equipment.
• Transmission of the hydrostatic type.

Principle of operation

Consider special equipment Works on the principle of aggregation of compressed air with the dye composition, which is fed into the working area when using the compressor, being divided into three parts. One of them falls into a tank of paint, a second thread comes in a container of solvent under pressure, and the third jet is directed into the gun. Future cover under pressure is crushed and forced out through the spray gun on the road.

The Advantages of this technique:

• You can use any materials without the filter, including paint AK-511.
• Hardware reliability and maintainability.
• Reasonable price and low operating costs.

The disadvantages of the unit include the wasteful consumption of compressed air and paint.

Airless modification

This category road equipment consists of the following main elements:

1. Gasoline internal combustion engine.
2. The Compressor.
3. Hydraulic high-pressure pump.
4. Capacity for paint and beads.
5. Spray.

The Principle of operation of special equipment of this type is based on the use of pressure with high scores. Injection is performed by means of the pump. The coating is supplied under the stress of 250 Bar to a diffuser and scatters into tiny particles, wherein the compressed air is not involved in the process. Dimensions of the applied markings are regulated by a nozzle replacement of different caliber.

Manual option

The Use of manual machinery for road marking does not require a highly skilled operator. This is due to the simplicity of the design and operation of equipment. Low weight and compact dimensions make it possible to use the unit in cramped urban conditions.

Building equipment

• Frame with a wheeled chassis.
• Powertrain: internal combustion.
• Steering column.
• A Reservoir for coloring material.
• Device marking image.

This equipment is operated airless the way, is transported manually or self-propelled way.

Other manufacturers

Among the manufacturers of road-marking machines are the following brands:

1. Graco. American modification, which every year usovershenstvuetsya, mastering various techniques of applying paint and coatings. Car Graco LineLazer are well known in the domestic market. A line of four kinds of machines can solve all the problems when using marking paint on the pavement, playgrounds, pedestrian crossings, and other areas.
2. Larius. The Italian model works top-pressure recovery method, is lightweight and maneuverability.
3. J. Wagner GmbH. The German firm more than 30 years producing road equipment. In Russia the company supplies relatively inexpensive car, reliable in marking and easy to operate.

6. ‘winner А622” from Smolensk designers is a trunk road marking machine. It is able to strike up to three white lines, and designed for continuous operation in high temperatures.
7. The Belarusian company “Steam” produces the whole range of road vehicles of high quality.

The Markup

Compared to paints, plastic counterparts have a life expectancy of one-third more. The markup applied by the main aggregates, clearly visible in clear weather, but in fog and at night visible not so good. Light reflection – one of the determining factors of the quality of the material. Such properties of the coating give the special components included in the hardened paint AK-511 or polymer coating.

To ensure the reflection of light microscopic balls only process that caused the image streaks or marks. Under its own weight, the components join in a common layer where frozen. The glow effect is achieved by displaying lights of car headlights in the driver's side.

Designations

The Application of signs on the road surface involves the following types:

• Solid and double solid line. The intersection of these elements is prohibited, they share the flow of vehicles coming in opposite directions.
• Dotted band. It also divides the flow of cars, however, her cross subject to other rules of the road.
• Line drawn transversely. They are mainly intended to regulate the movement of pedestrians. For drivers the markup – the indicator of the speed reduction and particular vigilance. Basic layout of transverse type indicates pedestrian crossing (“Zebra”).

Icons and arrows

Marking on roads in the form of icons involves displaying traits recognisable objects that you want to pay attention. For example, the character of the bike indicates the presence of bike lanes. A similar logo with a wheelchair indicates Parking for people with disabilities.

The thickness of the layer of the coated seat with the markup ranges from 0.8 mm in the processing of spray and up to three mm on a cold the thermoplastic. The arrows indicate the possible movement of vehicles or pedestrians. They can be single, doubles or triple the performance. On the active and meaningful tracks such markup is duplicated the appropriate sign.

Requirements

It Should be noted that the average life of a paint marking is six months, whereas the polymer coating provides 2-3 times longer. The optimum temperature for the application of the symbols is the figure in the range of 20 to 25 degrees Celsius. According to the state standards, the width of the marking may exceed the width of not more than 100 millimeters.

Inadequate lighting in Parking lots and car parks requires the implementation of the overall material reflective components. The location of fire hydrants, fire extinguishers, emergency exits are marked with fluorescent or luminous paints.

In conclusion

Correct road markings for Parking places must meet certain requirements:

1. Calculation of the dimensions of the cells and the width of the passages is performed with the possibility of arrival and departure of car, and possible plowing of the doors and around the Parking lot.
2. Measure width of travel – not less than 6 meters with the same rate of Parking space 2.5 m.
3. For vehicles driven by persons with disabilities, the second figure is increased to 3.5 meters.
4. Drawing of lines and other signs should be of cold plastic which is more resistant to mechanical impact and abrasion.
