Japan: New trucks can expand the body and protect road workers
Nagoya - At the highway construction site, an oncoming vehicle led to an increase in accidents and the development of a retractable truck ( Dongfeng truck parts, Sinotruk parts ) that provides road workers with a 23-meter-long protective barrier.
The 25-tonne car was built by the Japan Central Expressway Company. If it is not extended, the body is 16 meters long and 2.5 meters wide.
The protective barrier is made up of two 1.2-meter-high, 10-meter-long metal beams that form part of the body.
If a protective net is added, the barrier can reach 1.8 meters.
When the vehicle is parked on the highway, the beam closest to the shoulder moves toward the center so that it is flush with the other beam. Road workers can work safely in the space created by the beam movement.
According to the Japan Expressway Company, the car is equipped with shock absorbing equipment designed to protect workers from the impact of hitting the beam at a speed of 80 kilometers per hour.
At the end of this year, the safety truck will be put into use in construction sites in Aichi, Gifu and Mie Prefectures in the East China Sea.
The truck was developed in conjunction with Yokohama-based Toho Motors, which specializes in construction vehicles. The production cost of a truck is 40 million yen ($370,000).
The car was developed in August 2017, when a large truck hit a working vehicle parked on the central highway in Putian Island, killing a worker. Eight people, including other workers, truck drivers and drivers on the next national highway, were injured.
The number of accidents on the highway construction site managed by the Central Expressway in Japan has increased year by year.
The 149 incidents involving death, injury or property damage reported in the previous fiscal year were more than three times that of fiscal 2016.
According to the Central Japan Expressway, this type of protective car is the first of its kind in Japan. The United States has introduced a vehicle to protect road workers.
Japan’s Central Expressway Company said it will consider mass production after seeing the effects of the car.
