Product Description
A crash - cushion vehicle, also known as a Crash Energy Management Vehicle (CEMV), is a specialized vehicle with significant importance for road safety2. The following is a detailed introduction to it:
Definition and Basic Composition4
A crash - cushion vehicle is a mobile safety - protection device that installs a vehicle - mounted buffer device and a large - scale LED display on an automobile chassis. Its core component is the crash - cushion module, which is usually composed of a steel support frame and lightweight aluminum - alloy energy - absorbing barrels. In addition, the vehicle is also equipped with auxiliary devices such as large - scale LED warning lights, flashing indicator lights, a reversing camera, and a directional horn.
Working Principle3
When a following vehicle accidentally rushes into the construction - closed area and collides with the crash - cushion vehicle, the crash - cushion structure will undergo plastic deformation. Through this deformation, it can absorb the impact energy, reduce the impact force, and thus minimize the damage caused by the collision. This can protect the safety of personnel and equipment in the construction area to the greatest extent and also reduce the injury to the personnel in the impact vehicle.
Main Functions
- Safety Protection: Its primary function is to serve as a safety barrier, protecting the safety of construction personnel and equipment at the construction site3. Whether in road construction, maintenance, or traffic accident handling, it can prevent rear - end vehicles from impacting the front - line personnel and equipment, effectively reducing the damage caused by accidents.
- Warning and Guidance: The large - scale LED warning lights and flashing indicator lights equipped on the crash - cushion vehicle can remind rear - end drivers to pay attention to the road conditions from a long distance1. At the same time, some vehicles are also equipped with traffic guidance signs, which can be adjusted to prompts such as "Drive Left", "Drive Right", or "No Entry", guiding drivers to pass smoothly1.
The photovoltaic panel cleaning machine is a specialized equipment designed to maintain the efficiency of solar panels. With the rapid growth of solar energy, maintaining the cleanliness of panels has become crucial. This machine efficiently removes dust, dirt, and debris from the surface of photovoltaic panels, minimizing the loss of sunlight absorption and enhancing power generation efficiency. Its automated operation ensures minimal human intervention, reducing the risk of damage to panels. The cleaning machine is a vital tool for maintaining the long-term performance of solar installations, contributing to sustainable energy generation.
