Variable Stair

2012 Recommended Technology (New Technology Application Systems Review Meeting (Ministry of Land, Infrastructure, Transport and Tourism)) Registration Number: KT-090046—V

Since its foundation, Nisso Industries has promoted the development of scaffolding for construction, civil engineering, factories, and shipbuilding to ensure work safety in difficult construction areas and curved surfaces. To address the problem of frequent accidents of falling or stumbling during construction on slopes, Nisso Industries has applied its accumulated scaffolding engineering skills and capabilities to develop scaffolding for use on slopes that provides a high level of safety.

Against this background and as a measure to prevent accidents involving falling on slopes, between 2002 and 2012, the Ministry of Land, Infrastructure, Transport and Tourism proposed the installation of ascending/descending equipment on large-scale construction sites or sloped construction sites as one of its measures for the prevention of accidents. Thus, the product conforms to national safety policies.

This technology was designated as practical design comparison target technology under NETIS (New Technology Information System of the Ministry of Land, Infrastructure, Transport and Tourism) and selected as the recommended technology by the New Technology Application Systems Review Committee of the Ministry of Land, Infrastructure, Transport and Tourism in June 2012.

Features

Ideal for light to medium work on slopes with gradients between 20 to 75 degrees! Wide type, stationary slope installation type
Body: Three types are available: 1.2 m (Empty weight: 15 kg)/2 m (22.5 kg)/3 m (28.5 kg)
Load tolerance (Center-concentrated load): 250 kg
Lightweight aluminum structure makes for ease of carrying.
Comes as a single unit for extremely convenient assembly, dismantling, and turning compared to the previous single pipe + clamp pipe-step type
Footboards are always horizontal, and the unit has a handrail to provide security during work and moving.

Examples of Use

The Variable Stair Universal Unit offers a wide range of applications, including ascending and descending equipment for workers on gradients and slopes, as well as uses in civil engineering projects, architectural construction, bridge construction, soil erosion control, and river embankment improvements.
