Q1: What is this product?
This is a 20kg portable road work barrier (also known as a mini vehicle stopper/crash barrier) from China, brand RMHs. It is mainly used in low-speed environments such as road construction and temporary work zones to prevent vehicles from entering.
Q2: Why "20kg" and "1040mm height"?
20kg: The product has a net weight of only 20 kg, making it lightweight and easy to move by one person.
1040mm height: The unfolded height of the product is 894mm (close to the 1040mm class), which is a medium-height traffic barrier type that can effectively block and warn small vehicles.
Q3: What special feature does this barrier have?
It is not just an isolation barrier - it also has active stopping capability. When a vehicle hits it, the device uses a lever mechanism to lift the front wheel, combined with buffer modules and ground friction, to bring the vehicle to a smooth stop instead of being knocked away.
