Introduction

Tokyo Keiki, a pioneer in measurement instruments since the Meiji period, has proudly announced the launch of its latest innovation, the "Dump Sheet Opening Warning Device SA-1," set to hit the market in April 2025. This device is designed to enhance safety for dump truck operations by alerting drivers when their truck's dust prevention device is left open, significantly mitigating the risk of accidents related to cargo flow and structural collisions.

Background of Development

In Japan, regulations require vehicles that transport cargo to prevent any items from falling during transit. Typically, dump trucks are equipped with covers that surround the bed, ensuring safety during movement. However, there are instances when drivers unknowingly operate these trucks with the covers open, which can lead to hazardous accidents resulting in property damage and personal injury. To combat human error, it is paramount to reduce the burden of safety checks for drivers. To address this critical issue, Tokyo Keiki collaborated with Nippon Doro Co., Ltd. and ND Lease System Co., Ltd. to develop this warning device.

Product Features

The Dump Sheet Opening Warning Device SA-1 is designed to prevent forgetfulness in closing the dust prevention device while on the road. Here are some of its standout features:

1. Easy Installation

The alarm unit connects via USB power and utilizes magnets for sensor attachment, eliminating the need for any tools. The wireless communication between the alarm and sensor means there’s no hassle with wiring.

2. Robust Design

Engineered for durability, the sensor is both dust-proof and waterproof (IP65), ensuring reliable performance even in adverse weather conditions. The alarm unit will notify users via sound alerts if the sensor's battery is low or if there’s any communication disruption.

3. Compact and Lightweight

Its palm-sized design makes it convenient to handle without taking up unnecessary space.

4. Multifunctional Design

Despite its simplicity, the alarm features multiple functions, including volume adjustment across three levels and a temporary mute option that automatically resets after five minutes.
