Dear Customer,
Here is a list of dock bollard replacement projects from other customers.
The customer removed the original dock bollard and installed the bollard purchased from Henegr
Before placing the order, the customer checked the technical details with us and adopted the solution we provided. After placing the order, the customer chose to come to the factory to inspect the product. Now the bollard has been installed on the dock.
The Henger team has won the customer's recognition with its high professionalism and active service.
If you have any related marine product procurement projects, you are welcome to share!
The rotating anti-collision guardrail consists of a column, a rotating barrel, a U-shaped beam and a connector. All steel components are hot-dip galvanized to prevent rust. The columns are 1 meter or 0.7 meters apart, and two rotating barrels are installed on each column. The rotating barrel is made of EVA (ethylene-vinyl acetate copolymer) as the main material, and 17 auxiliary materials such as PE (polyethylene) and related chemical additives are added. It is produced under a certain temperature and pressure and has high flexibility. It has high heat resistance and high temperature resistance, and the continuous working temperature is between -60°C and 70°C.
Rotating anti-collision guardrail specifications: column φ140mm×4.5mm×length; crossbar 115mm×82mm×4mm×length; sleeve 105mm×63mm×4mm×length; rotating barrel 350mm×238mm; gyroscopic circle 22mm0×5mm; can be divided into 700mm spacing and 1000mm spacing.
Function of the rotating anti-collision guardrail: As a longitudinal energy-absorbing structure, the rotating anti-collision corrugated guardrail absorbs collision energy by self-deformation or vehicle climbing, thereby changing the direction of the vehicle, preventing the vehicle from going off the road or entering the opposite lane, and minimizing the damage to the passengers. It is particularly effective in preventing vehicles from going off the road or crossing the central dividing strip into the opposite lane, and preventing vehicles from getting out from under the guardrail; in the event of a collision, the degree of damage to the passengers will be greatly reduced.
Installation of rotating anti-collision guardrail:
1) Post: driven into the roadbed, which is the main force-bearing component.
2) Beam: used to connect the posts and fix the rotating barrel.
3) Rotating barrel: fixed between the upper and lower beams, can rotate around the post, the main materials are EVA (ethylene-ester copolymer) and polyurethane.
4) Sleeve: installed on the inner wall of the rotating barrel, the contact part of the rotating function.
5) Turning ring: installed between the rotating barrel and the beam, balance and promote rotation.
6) Connecting frame: used for connecting between beams.
7) U-shaped frame: connects the beam and the column, used to fix the beam.
8) Pad buckle: lined with the beam, connected to the U-shaped frame.
9) Hoop: connects the beam and the column, used to fix the beam, suitable for specific models.
10) Reflective strip. It is a reflective film, pasted on the rotating barrel, which plays an inductive role.
How roller barrier safety works?
1. The rotating barrel converts great shock from vehicle collision to rotational energy to absorb shock.
2. Upper and lower frames adjust tires of large and small vehicles to prevent the steering system function loss.
3. The three-dimensional structure of D-shaped frame and buffering bracket distribute and absorb the 2nd shock.
4. Props at an interval of 0.7 m increase bearing power to prevent accident vehicles from going over the guardrail and turning over into a dangerous area.
5. The product has a rotating barrel made of EVA with excellent shock absorption power, three-dimensional buffering frames and dense props supporting the frames.
In China, roadside guardrails are made of hard metal materials. Once a car accident occurs, the passengers are likely to suffer secondary injuries from the guardrails. Recently, a popular guardrail on the Internet has quietly appeared in our field of vision. The principle of this invention is to convert the impact force into rotational kinetic energy through a rotating device, thereby absorbing the impact force and greatly reducing the occurrence of traffic accidents. It is reported that this "rotating guardrail" has appeared in the United States, South Korea, Japan and other places. Some areas in China have also begun testing and applying it.
my country's highways use guardrails made of hard metal. Once a car accident occurs, it is likely that the guardrail will cause secondary injuries. Once the "rotating guardrail" is used, it will save countless lives.
This is the guardrail with the rotating device installed.
When the car hits the guardrail with a rotating device
Let's look at the protective effect from another angle. We can see that the car will not lose control and rush out of the guardrail. Once the "rotating guardrail" is applied, it will save countless lives.
Let's take a look at buses, no problem!
Once the "rotating guardrail" is applied, it will save countless lives
The principle of the "rotating guardrail" is very simple - it mainly rotates!
When a vehicle loses control and crashes into the "rotating guardrail", these rollers will roll at high speed. Once the "rotating guardrail" is applied, it will save countless lives. The impact force is converted into rotational kinetic energy through the rotating device, thereby absorbing the impact force and greatly reducing the occurrence of traffic accidents.
