Stage Tower®

Thoughts on Development

The biggest concern in silo maintenance is industrial accidents. In particular, fatal accidents due to grain collapse occur frequently at silo-owning companies nationwide. The reasons for this include the lack of installation of safety equipment due to the inability to secure scaffolding during work and the construction from the outlet at the bottom of the silo. With a strong desire to eliminate work-related accidents, we developed the Stage Tower after struggling to find a safe, efficient and low-cost method of construction.

What is Stage Tower® ?

Stage Tower is a special mobile scaffold developed for inspection, cleaning, bridging, and construction works inside silos and tanks. The scaffolding for one step of single-pipe scaffolding automatically moves freely up and down in the silo like an elevator. We have obtained patents for the construction methods using our proprietary Stage Tower.



Shape and Size

The shape of the Stage Tower can accommodate all sizes of main bins, sub bins and tanks.

You can clean, inspect and repair every nook and cranny in the silo.


Lightweight Structure

Material-efficient, less energy and easy to mobilize. It moves freely up and down in the silo.


Structure Safety

Multiple measures are in place to prevent falls. In 2011, on Tohoku Earthquake and Tsunami in Japan, we were working on the Stage Tower installed in the disaster area. There was no damage to the platform and the workers were able to safely evacuate from silo
