A Game Changer in Construction Safety: The Slope Eye

On March 9, 2026, Rental Nikkens, headquartered in Minato, Tokyo, unveiled a groundbreaking product designed to enhance safety at construction sites: the Slope Eye. This innovative visual inspection tool enables users to quickly determine whether the slope gradient of a safety ramp is within the safety limits required for aerial work platforms.

Background of Development

At construction sites, accidents involving aerial work platforms, such as table lifts, often occur when navigating sloped safety ramps. One major contributor to these incidents is the slope exceeding the legally mandated gradient of 1/8 (approximately 7.1 degrees). However, on-site conditions reveal a persistent issue where:

• - There are no available tools for measuring the slope.
• - The measurement process is labor-intensive.
• - Workers must rely on their experience and intuition.

As a result, hazards go unnoticed, leading to dangerous operational conditions. To address this critical issue, the Slope Eye was developed. Designed for ease of use, this tool allows quick visual assessments of whether a ramp's slope is within safe limits, eliminating the need for specialized knowledge or complicated measurement tasks. With the introduction of this product, we anticipate a significant reduction in accidents involving aerial work platforms and an overall increase in safety at construction sites.

Features of the Slope Eye

1. Instant Visual Assessment Tool
The Slope Eye allows users to easily check if the ramp gradient is within the safe 1/8 threshold by simply placing the tool against the slope. This feature ensures that anyone can verify safety standards without extensive training or prior expertise.

2. Compact Card-Sized Design
With a pocket-sized format, the Slope Eye is easy to carry and store, enhancing portability on site. Its compact design ensures that it can be readily available when needed, providing workers with the necessary tools for immediate safety checks.

3. Consistent Safety Management
This tool eliminates reliance on personal experience or judgment. Regardless of a worker's expertise level, the Slope Eye allows for uniform and precise safety assessments.

As Rental Nikkens continues to innovate, the company remains committed to fostering visibility of risks within construction environments. By developing and providing tools like the Slope Eye, we aim to contribute significantly to injury prevention and improved safety standards in the industry. This innovative product not only marks a step forward in terms of occupational safety but also sets a precedent for future advancements in construction safety technologies.
