Lifting column, also known as lifting ground column, lifting road pile, anti-collision road pile, hydraulic lifting column, isolation pile and so on. English name Bollard. The term Bollard was originally used to describe a short, vertical column that was often used when large vessels in the port were moored. Now its meaning has been expanded to describe various facilities that manage pedestrian traffic, protect critical infrastructure, set perimeters, and differentiate roads.
Modern lifting columns are widely used in urban transportation, military dui and major national government gates and surrounding areas, pedestrian streets, highway toll stations, airports, schools, banks, large clubs, parking lots and many other occasions. Through the restrictions on passing vehicles, the traffic order and the safety of major facilities and places are effectively guaranteed.
According to legend, the street guardrail began in the 17th century and is shaped like an inverted cannon, used as a boundary setting and a city sign. Since then, they have appeared more and more in our daily lives, such as supermarkets, restaurants, hotels, shops and stadiums. We can often see bracelets of different shapes, either to indicate the direction of travel, or to protect us from injury, or to tell if parking is possible here. These beautifully shaped bollards landscaping the environment, distinguishing between sidewalks and roadways, and sometimes as chairs allow us to sit down and enjoy lunch.
With the strengthening of the domestic fan terror situation, the protection of sensitive areas of buildings is particularly important. Lifting columns are being accepted by more and more users due to their many advantages such as safety and beauty.
For some high-security applications, such as military bases, etc., it is necessary to use anti-terrorism level lifting columns. Compared with the general civilian grade lifting column, the cylinder thickness generally needs to reach 12mm or more, while the general civil grade lifting column is 3-6mm. In addition, the installation requirements are not the same. At present, there are two international certification standards for high-security fans. The first PAS68 certification (with the PAS69 installation standard); Second, the US Department of Foreign Affairs Security Bureau DOS certification. The 7.5T truck was tested to hit at 80KM/H, the truck was prevented from being in place, and the roadblock (lifting column, road pile) was working as usual.
For the civilian-grade lifting column, although the performance is slightly worse than the anti-terrorism level lifting column, its protective performance can fully meet the needs of civil security, and it is frequently used in daily life. It is suitable for vehicle access control places with large traffic volume and medium safety requirements. Can be widely used in banks, government agencies, research and development centers, power stations, highways, industrial parks, high-end villas, high-end office buildings, luxury goods stores, pedestrian streets and other places.
Use range:
Products are widely used in urban transportation, military dui and national important institutions and surrounding areas, pedestrian streets, highways, toll stations, airports, schools, banks, large clubs, parking lots and many other occasions. Through the restrictions on passing vehicles, the traffic order, that is, the safety of major facilities and places is effectively guaranteed.
1. Gates of important units such as state organs and military dui : install lifting and riot-proof roadblocks, and control the lifting by electric, remote control or credit card, effectively preventing the entry of external unit vehicles and illegal vehicles.
2. Pedestrian Street: Install a lifting roadblock at the intersection of the pedestrian street. The roadblock is in a raised state and restricts the entry and exit of the vehicle. In case of emergency or special circumstances (such as fire, first aid, leadership inspection, etc.), the roadblock can be quickly lowered to allow the vehicle to pass.
3. Road isolation belt: In the non-fully enclosed road isolation belt, a lifting road barrier can be used, which usually prevents the vehicle from turning left or turning around. In case of special conditions such as road construction and road blockage, roadblocks can be lowered to allow vehicles to be diverted.
4. Multi-purpose plaza: During the daytime, roadblocks rise, vehicles are prohibited from entering the plaza, and the plaza is used as a temporary parking lot at night, and the roadblocks are put down, and the vehicles can enter the parking.
5. Open parks: Elevated roadblocks are installed at open park intersections. Usually, roadblocks rise to prevent vehicles from passing, and visitors can pass freely. In case of special circumstances, lower the lift barrier to allow the vehicle to pass.
6, the community, banks, schools and other places that restrict the entry of vehicles and ensure the effective use of fire exits.
7. Expressway: It is necessary to urgently close the road and use the automatic lifting road pile, which is convenient and quick, and can solve the pressure of insufficient police force.
An Angle Grinder Machine, also known as a side grinder or disc grinder, is a handheld power tool used for grinding (abrasive cutting) and polishing.
Angle Grinders can be powered by an electric motor, petrol engine or compressed air. The motor drives a geared head at a right-angle on which is mounted an abrasive disc or a thinner cut-off disc, either of which can be replaced when worn. Angle grinders typically have an adjustable guard and a side-handle for two-handed operation. Certain angle grinders, depending on their speed range, can be used as sanders, employing a sanding disc with a backing pad or disc. The backing system is typically made of hard plastic, phenolic resin, or medium-hard rubber depending on the amount of flexibility desired.
Angle grinders are standard equipment in metal fabrication shops and on construction sites. They are also common in machine shops, along with die grinders and Bench Grinders.
