Folding stairs is specially designed to provide safe and efficient means of access between a loading platform and road or rail tankers.
The principle is a four-bar mechanism, parallelogram shaped, keeping each treadle parallel to the ground during stair rotation in order to make sure that the operator standing upright while walking.
Over-turning moment of the stair keeps balance by spring cylinder consisting of several sets of inbuilt spring, saving labor during folding and unfolding operation. Folding stairs mainly consists of the treadle, handrail, spring cylinder balance system, and locking mechanism, featuring novel structure, easy operation (by one person), reliable and safe operation.
The whole body is galvanized with nice appearance, anti-corrosion, and durability. The treadle is made from dentiform grid plate with good non-skid performance. Contact area employs oil-resistant rubber part to prevent from the spark caused by the collision. Maximum design load is more than 300kg.
