Folding Stairs
 
Folding stairs is especially designed to provide safe and efficient means of access between a loading platform and road or rail tankers.
 
The principle is four-bar mechanism, parallelogram shaped, keeping each step parallel to the ground during stair rotation to ensure 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. A folding stair mainly consists of steps, handrail, spring cylinder balance system and locking mechanism, featuring novel structure, easy operation (by one person), reliable and safe operation.
 
The whole body is made of carbon steel and hot-dip galvanized with nice appearance, anti-corrosion and durability. The steps are with good non-skid performance. Contact area employs oil-resistant rubber part to prevent from spark caused by collision.
The surface treatment of spring cylinder is sand blasting and painted.
 
Features:
Full hot-dip galvanizing treatment, anti-corrosion, rust-proof and durable.
Fully balanced self levelling steps to automatically adjust to varying tanker heights
Anti-slip grating steps
Safety handrails and knee guards fitted as standard
Rubber bumper to prevent tanker damage and static discharge
Pull-rope to assist returning stairs to rest position
