Can be added to existing trailers. A dedicated backup sonar that supports detaching the cargo area covers blind spots of the connected vehicle and prevents backing accidents.

The "trailer back sonar" provided by Hachiyou Densou is a solution that addresses the "blind spots" of vehicles, which are a challenge in the logistics industry, contributing to accident prevention and safety measures. It has been developed in collaboration with major commercial vehicle manufacturers to set detection ranges that meet on-site needs. The biggest feature is its compatibility with the unique "detachable operation of the cargo area" specific to trailers. By adopting waterproof connectors, it allows for the connection and disconnection of the harness between the main unit and the sonar sensor. This enables the connection and disconnection of the sonar system between the tractor and trailer, ensuring safety for coupled vehicles, which was difficult with traditional wired sensors, and allows for retrofitting to existing operational vehicles. The ultrasonic sensor elements are designed and developed by a domestic manufacturer that boasts a 60% share of the global market (manufactured at its overseas factory), providing high durability and precision as strengths. The track record extends beyond trailers to major logistics companies, including those overseas, as well as city buses, sightseeing buses, camper vans, fire trucks, packer trucks, and other special vehicles, encompassing all commercial vehicles, with a cumulative installation count of over 20,000 units. It is a practical product that meets the safety needs of the field.

basic information

【Basic Specifications and Detailed Specs】 ■Target Vehicles: Large commercial vehicles such as trailers, articulated vehicles, and trucks (can be retrofitted to existing operational vehicles) ■Operating Conditions (Speed-Linked Function): The system automatically activates during low-speed driving at approximately 10 km/h or less. It is specialized for safety checks during low-speed reversing and just before stopping, covering blind spots in front and behind the vehicle. ■Detection Distance and Alerts: Sensors detect distances of "100 cm" and "180 cm" from the rear of the vehicle. When approaching an obstacle, a warning sound and flashing lights alert the driver in the driver's seat. ■System Structure: Connection and disconnection function of the sonar system between the cabin (driver's seat) and the cargo area (fully compatible with the trailer-specific cargo separation operations) ■Quality and Durability: Co-developed with major commercial vehicle manufacturers. Designed for high durability that meets the standards of commercial vehicles used for extended periods in harsh environments. *For detailed installation conditions and compatibility confirmation, please feel free to contact us. First, please download the materials and take a look.

There are installation records on a two-axle trailer with a front length of 12m and a rear length of 17m. If multiple container trucks are equipped with one tractor head, each can be accommodated. Designed by a reliable domestic manufacturer, it is produced in our overseas factory and is also evaluated for cost-effectiveness. There has been a significant demand from overseas, particularly from the Asian region, and our network of overseas distributors is expanding. Installation records of our sonar system series for commercial vehicles: ◇ Transportation-related adoption records (in no particular order): Bait Transport: Over 100 units Nippon Express: Over 2000 units Co-op: Over 500 units across the country ◇ Bus-related adoption records (in no particular order): Tokyo Metropolitan Bus: Over 1000 units Yokohama City Bus: Over 200 units Keisei Bus Group: Over 1000 units for route/tourist/limousine buses Kanagawa Chuo Kotsu: Currently in trial operation Many other major bus companies ◇ Dealer installation records (in no particular order): Hino Motors: Over 1500 units Isuzu Motors: Over 200 units Scania Japan: 30 units

Founded 91 years ago as "Yashima Automobile Parts Trading Company," our company originated from the automotive parts division of Yashima Motor Co., which was the general importer of Chrysler vehicles in 1926. Over the years, we evolved from supplying repair parts to directly providing mass-produced components to automobile manufacturers, in line with the pre-war and post-war trends of domestic automobile production. At the time of our establishment, the Toranomon area was referred to as Japan's Detroit, yet there were almost no domestic vehicles present, and we had been engaged in automotive-related business even before the domestic production of automobiles began. Today, we have transformed and grown into a technical trading company that directly supplies and sells mass-produced parts to major automobile manufacturers and construction machinery manufacturers. We support the development departments of manufacturers with technical proposals and assist the procurement departments with global parts sourcing, providing mass production solutions for a wide range of products, from resin molded products, semiconductors, electronic components, and sensors to inverters and onboard motors that make up electric vehicles. Notably, the next-generation onboard electrification components have significantly increased, with mass production sales reaching an annual scale of 6 billion yen.
