As you can see, in the title of our road marking machines, there are three high frequency words: driving-type, self-propelled, hand-push. For example, DY-BTSC driving-type thermoplastic screeding road marking machine, DY-SPT self-propelled thermoplastic screeding road marking machine, DY-HPT hand-push thermoplastic screeding road marking machine.
According to the individual marking jobs and local circumstances, road marking machines are divided into two groups:
1. Hand guided machines
Some of them having their own drive system, where the operator walks behind the machine steering and controlling the direction. Normally such type of machines has a material container capacity of approx. 20 – 50L for glass beads and approx. 100L for hot plastic.
Typical areas of operation are: parking lots, intersections, industrial areas, sports grounds and smaller road marking applications.
2. Self-propelled machines
Middle-size, big-size as well as truck-mounted road marking machines with varying material container capacities of approx. 200 L – 3000L proportionally to the size of the machine and the marking material to be applied.
Typical fields of operation are: Town and highway markings as well as motor ways and airport markings.
There are three ways to mark the roads with information. One way is to paint the information onto the surface, another is by applying thermoplastic road markings and the last way is by temporary road marking tape.
The road markings are usually made with a special spray machine and it is then applied to the road at a slow pace. Painting the roads is a low cost option but it doesn't offer the grip that rival systems do. Another disadvantage is that painting is extremely hard to remove.
Hot Applied Thermoplastic Road Markings
Advantages include good durability, transfer from machine to road quickly low cost and have a high skid resistance. This form is used throughout the network as a permanent marking.
Temporary Road Marking Tape
When transferred onto the road it is durable for at least three months. It offers good skid resistance however it is quite expensive and is slow to apply due to the nature of having to lay it. Its biggest disadvantage is that it will not stick to the carriageway in wet or cold conditions.
1. Concept of Road Marking Machine.
Road Marking Machine, herein means the aggregate of hand-push type machine, self-propelled type machine, sitting type machine, thermoplastic type machine and cold painting type machine, which is used to mark line on road. It is mainly used in car park, avenues, streets, highway, etc.
2. How does it work?
In terms of thermoplastic type machine, at first we need heating and mix the paint within the thermoplastic pre-heater, and then put the paint into the paint tank of thermoplastic type machine, than we can drive this machine to mark line: Paint from the paint tank out, after crossed the marking shoes, ultimately falls on the road.
In terms of cold paint type machine, we needn’t heating and mix the paint. Only put the paint into paint tank of cold paint type machine, than we can drive this machine to mark line: Paint is pumped from the paint tank, after crossed the marking shoes, ultimately falls on the road.
These machines designed and manufactured by China Dayu Machinery Company have been widely applied to many pavement construction. The quality of the construction reaches GB standard. It contribute to improve the convinience and safety for avenues, streets, highway, etc.
1. Who is the first to develop center lines?
In the United States, two states claim to be the first to have developed center lines. According to the state of Michigan, painted white center lines were developed by Edward N. Hines, the chairman of the Wayne County, Michigan, Board of Roads. They were first used on roads in Michigan around 1911. According to the state of California, Dr. June Mc Carroll was the first to develop center lines, in 1917. In 2002, a portion of Interstate 10 was designated and signed as "The Doctor June Mc Carroll Memorial Freeway" in her honor.
2. The first experiment of center white line in England.
In England, the idea of painting a centre white line was first experimented with in 1921 in Sutton Coldfield, Birmingham. Following complaints by residents over reckless driving and several collisions, the Sutton Cold field Corporation decided to paint the line on Maney Corner in the area of Maney.
3. The function of line.
The line was put down as an experiment as there were a lot of accidents there, even in the early days of the motor car. The experiment proved to be so successful that the whole country adopted it as a standard road safety device, and later foreign countries put white line on their roads, too.
