• DONGFENG TIANJIN brand anti-collision buffer truck adopts JMC chassis. The lifting and droping of the anti-collision buffer module adopts hydraulic control, stable and safe process, higher degree of mechanized operation, convenient operation. The whole anti-collision buffer module is introduced the 100E anti-collision buffer module from Chinamade Shenzhen Qianxingda Technology Co., Ltd.
•  
• This car is suitable for urban roads, suburban roads, highways, airport bridges and culverts and other occasions.
• Main function of anti-collision buffer car is as below.:
• The anti-collision buffer car is placed behind road construction workers and equipment, and acts as a buffer area for the vehicle and construction workers or equipment in the event of a rear-end accident collision, and absorbs impact energy through its own structural deformation, minimizing the danger of construction workers or equipment. The probability of accident, while minimizing the risk of the vehicle and personnel involved in the accident.
•  
• The impact energy is absorbed by the self-deformation of the anti-collision cushion to protect the life safety of the driver and passenger of the rear-end vehicle and the construction personnel on the front side
•  
• During road construction and maintenance, pavement workers often work near the moving lanes of vehicles. Although, various means are used to direct traffic away from the work area, such as barrier piers, traffic markings, warning poles and signal lights. But for a variety of reasons, the wrong vehicle can enter an area that is not drivable and has workers.

Truck chassis: 
Dongfeng Tianjin high class truck chassis, truck chassis model: DFH1160BX1, D4.0NS6B195 195hp Euro Ⅵ diesel engine, DT0690 dongfeng 6 speed manual gearbox, 3950mm wheelbase, 3.6T front axle/8T rear axle, 9.00R20 rail tires, original air conditioner, etc. 

The cargo body box adopts Q235 3mm thickness side sheet and 4mm thickness for bottom sheet.
And the rear anti-collision buffer module package of the cargo box adopts the internationally renowned technical product 100E anti-collision buffer module. The anti-collision buffer energy-absorbing module is mainly composed of a vehicle-mounted anti-collision buffer pad and a guide sign frame, which acts as a buffer guard behind the construction vehicle. In the event of a rear-end collision, a buffer area can be constructed between the vehicle involved and the construction area ahead, and the impact energy can be absorbed through structural deformation of the machine tool, thereby minimizing the chance of collision of protected personnel and equipment. High-performance hydraulic system can realize rapid lifting and dropping operation, convenient for equipment transportation and transition, one-key start function, lifting and falling anti-collision device, when the anti-collision device is not completely lowered to the working position or lifted to the vertical transport position , there will be an automatic warning sound prompt.

Main structure and working principle
The upper part of the anti-collision buffer truck is mainly composed of the cargo box assembly, the induction combination lamp, the anti-collision buffer module, the hydraulic system and the electrical system. The lifting and dropping of the anti-collision buffer module is controlled by the oil circuit, and the anti-collision module is in a horizontal state in the working state. .
The VIN marking is on the front right side of the chassis frame. (For details, please refer to the introduction of the chassis manual)

2, cargo box
The material is Q235 WISCO carbon steel plate. The cargo box is composed of a bottom frame and side panels, which are connected to the chassis girder through U-bolts, which can be used for loading tools, accessories and other items. There is a side door in the middle of the cargo box, which is convenient for construction and operation.
 

3, Induction light
It is composed of LED lights, and can achieve three different working modes: left induction, right induction, and both sides induction through different arrangements and combinations.

 
Anti-collision module
The cargo body box adopts Q235 national standard 3mm thickness for side sheet and 4mm thickness for bottom sheet. And the rear anti-collision bag of the box adopts the CANSINGA-TMA 100E model produced by a well-known China domestic company: Shenzhen Qianxingda Technology Co., Ltd., with a high-performance hydraulic system, which can achieve rapid lifting and Drop operation, convenient for equipment transportation and transition, one-key start function, equipped with customized warning lights, LED warning display.
passed the American MASH2016 crash test((2.2t，100km/h, can absorb the impact energy of a 2-ton vehicle at a speed of 70km/h anti-collision The interior of the cushion is filled with aerospace-grade cushioning material), and also passed Test-50、Test-51、Test-52、Test-53. When an accidental rear-end collision occurs with a vehicle, the cushioning material is compressed and deformed, thereby absorbing the collision energy.

The main function of the anti-collision buffer device
The main function of the anti-collision buffer device is to provide comprehensive and passive safety protection for road maintenance workers and equipment in temporarily closed sections of lanes. The impact energy is absorbed by the deformation of the anti-collision cushion, which effectively protects the construction personnel and equipment, and at the same time protects the safety of the personnel in the collision vehicle to the greatest extent. The maximum anti-collision buffer level of the crash pad is 2000kg-70km/h. The aviation aluminum film peak and dimple material used in the crash pad will undergo controllable deformation to effectively absorb the collision energy. The buffer module can be moved up and down and locked in two positions. When in operation, the module: will be locked in a horizontal position. When driving, the module will be locked in the upright position to improve the driving performance. Construction of daily maintenance of expressways and municipal roads.
