Buzzer absorbent material traction type anti-collision absorption
device is installed on the rear of road maintenance vehicles to
prevent collisions and provide shock absorption, protecting the
safety of both people and vehicles.
The product features an electrostatic spraying process on the
exterior, ensuring rust resistance even under outdoor conditions.
The yellow body with red and white warning strips provides
excellent visibility and warning effects for drivers. When
impacted, the specialized aluminum profile inside absorbs
significant impact force through its structural shock absorption
principle, minimizing accident damage. For minor deformations,
repair work can be easily completed by replacing the internal
absorbent material.

A strobe light and alarm are installed on the top of the product,
providing clear warning signals when accidents occur.

Application Scenarios
The RMHs Fixed Rear Guard is primarily designed for safety
protection scenarios of special operation vehicles, including:
- Municipal operation scenarios: Road maintenance vehicles, street sweepers, and sprinklers during
parking operations such as road patching, cleaning, and greening
irrigation
- Special operation scenarios: Tunnel cleaning trucks and emergency rescue vehicles working in
enclosed or semi-enclosed spaces, or at emergency accident sites
- Temporary operation scenarios: Serving as mobile safety barriers in road construction enclosure
areas and emergency repair sites

Frequently Asked Questions
What speed of impact can this product withstand?
The product has passed Japanese standard tests and can effectively
protect against rear-end collisions at speeds below 80km/h. The
actual protection capability depends on multiple factors such as
collision angle and vehicle weight.
Will installation affect vehicle passability?
The standard size is designed with the departure angle of common
vehicles in mind. After installation, the ground clearance is
approximately 30cm, which does not affect normal road driving. For
special terrains, please choose a customized height.
Can it really be repaired after a collision? What is the repair
cost?
Yes, our honeycomb energy-absorbing structure has shape recovery
characteristics. Moderate deformation can be repaired with
professional tools, and the specific repair plan needs to be
evaluated by technical personnel.
How long is the customization cycle?
Standard products are in sufficient stock. Customized products
require 15-30 working days depending on the complexity. Urgent
needs can be processed with expedited service.
Which countries' road standards is it applicable to?
The product complies with road safety standards of multiple
countries including Japan and the European Union. Users should use
it in accordance with local regulations.
Is this product suitable for small work vehicles?
The standard size of the product is suitable for medium and large
special work vehicles. If it is to be used for small vehicles,
please provide the tail size and load-bearing data of the vehicle.
We can meet the requirements through customized services to ensure
that the installation does not affect vehicle driving and
operation.
Will the protective performance decrease after the energy-absorbing
module is repaired?
No. The energy-absorbing module of the product adopts a recoverable
design. After professional repair, it will pass performance testing
to ensure that its energy absorption efficiency and protection
capability are consistent with new modules, fully complying with
safety standards.
The product weighs 96kg, will it increase vehicle fuel consumption?
The product is made of lightweight aluminum alloy material, which
is more than 30% lighter than similar steel products. The impact on
the fuel consumption of large work vehicles is negligible, and its
safety protection value is far higher than the slight increase in
fuel costs.
