Pneumatic Foldable Stair
The Foldable Stair is designed to ensure safe access for operators between the fixed platform and the tops of tank trucks at different heights.
As a standard product, the Foldable Stair is equipped with self-locking steps, a spring cylinder balancing mechanism, hand and knee guardrails, and flip-up toe boards.
The surface protection can be painting after sandblasting (Sa 2.5) or hot-dip galvanizing.

Equipment Features
The Pneumatic Foldable Stair retains all performance parameters of the standard foldable stair while adding a pneumatic system. The pneumatic system drives the cylinder, which, combined with the spring cylinder balancing mechanism, enables automatic extension and retraction of the stair. This eliminates the need for manual operation, reduces operator labor, and improves work efficiency.
In particular, when the stair is equipped with guardrails, the downward tilt angle reaches 45° and the upward tilt angle reaches 87°, providing a wide operating range. The Pneumatic Foldable Stair can serve not only as a complementary device for marine loading arms but also in other scenarios requiring elevated cross-over access.
Through optimized design, this pneumatic system can be applied to various types of foldable stairs.
