Rubber speed hump, rubber road hump
Installed on the road to slow down the vehicle through the transport facilities, the shape is generally strip, but also a bit like, the material is mainly rubber, there is a metal, generally yellow and black to cause visual attention, so that the road slightly arched to To slow down the speed of motor vehicles, non-motor vehicles to use the speed of the new transport (such as the use of motor vehicles, motor vehicles, motor vehicles, motor vehicles, motor vehicles, Dedicated security settings.
Rubber speed hump, rubber road hump
So that the road slightly arched in order to achieve the purpose of vehicle deceleration, generally set at the highway crossing, industrial and mining enterprises, schools, residential area entrance and other vehicles need to slow down the road sections and easily lead to traffic accidents, is used to slow down the vehicle, Motor vehicles to exercise speed of the new traffic-specific security settings. Deceleration with a large extent to reduce the traffic thoroughfares of the accident, traffic safety is a new type of special facilities. The car is safe in the driving and buffer buffering purposes, to improve the safety of traffic crossing. At present, the deceleration zone in the rest of the world's roads have been widely used.
Material classification / Rubber speed hump, rubber road hump
Deceleration with rubber deceleration zone in accordance with the car in the tire and ground special rubber angle design, with special rubber. Is a set in the road crossing, industrial and mining enterprises, schools, residential and other entrance for the slowdown in motor vehicles, non-motor vehicle speed of the new traffic-specific security settings. The product with the original ridge of cement, compared to the rubber deceleration with a shock absorption, excellent compression, long life, less wear on the car, less noise, yellow and black and white, clear color, without re-painted every year, beautiful Generous and so on. With the use of products with a slowdown, a significant reduction in the traffic thoroughfares of the accident, is a new type of traffic safety facilities. National highway and highway are not suitable for installation.
Before 1997, only foreign companies in the market in the production and sale of rubber deceleration zone, which is equipped with reflective beads. In foreign countries it also has an alias called "lying police
When the main domestic use of cement and cast iron to do deceleration with rubber deceleration with a certain degree of flexibility in the impact of the vehicle did not have a strong sense of turbulence, by reducing the speed of the vehicle to reduce the speed,
Rubber speed hump, rubber road hump
Shock, shock-absorbing effect. During the day and see the black and yellow, reflective beads at night to see the reflected light, especially eye-catching. Installation is simple, easy maintenance. Later, many of the country's rubber manufacturers imitate this style.
In the deceleration zone on both sides of the central have a small hole, is the installation of holes, with expansion screws will be fixed to the road with slowdown. So when the vehicle rolling deceleration zone with the most force when the installation hole, the first part of the tear is connected hole position, so the deceleration slope off, nails exposed. 1. The steel studs will pierce the wheel tires. The main cause of this situation is cut corners, with the recovery of rubber in the large number of low-cost additives, material strength greatly decreased. To avoid this problem, we must use natural rubber, do not use recycled rubber. Do not add a lot of low-cost additives. The connection holes are lined with steel plates and are connected to each other. In the vulcanization processing of rubber products, the installation of a steel plate inside the deceleration zone, respectively, the two holes connected to the expansion screws in the installation also through the steel plate, an increase of the strength of connecting holes, leaving the size of steel plate holes, Better combination with rubber. A meridian is added to strengthen the strength.
Rubber deceleration zone with the test equipment to simulate the wheel rolling, observation of rubber deceleration with the damage situation, the rubber deceleration belt fixed on the plate, open the motor, the wheel rotation, rolling rubber reducer belt to test its life.
Cast steel
Steel deceleration zone cast steel deceleration zone, is the use of special steel production, specifications in 250 * 350 * 50mm, yellow and black color, bearing more than 200 tons, commonly used in: highways, gas stations,
Urban junctions, toll stations, etc. more than 200 tons of motor vehicle export zone. Cast steel deceleration pad wear resistance, bearing gravity, deformation, life is 5-10 times the rubber pad; rubber deceleration pad damaged, not
In particular, heavy vehicles in the past (such as toll stations, port terminals, large freight yard, etc.) or can be installed in the original location of the new pad, and the old installation position of the screws left on the vehicle tire wear large and even security risks;
The installation of deceleration pad location (such as construction sites, electronic platform for the import and export, underground parking garage slopes, etc.) of the place, the use of our cast steel deceleration pad can effectively solve the above problems.
Composition and general requirements / Reduction zone
1.1 Composition
Rubber deceleration ridge by the yellow, black and white rubber ridge units.
1.2 General requirements
Rubber deceleration ridge should be one piece, the outer surface should have increased adhesion stripes. Each slowdown ridge unit is in the vehicle traveling direction with a retroreflective material that facilitates night-time identification.
