Movable Ladder, Folding Stairs, Folding Ladder for Petrochemical Industrial

  CPEPT 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 tread 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. Folding stairs mainly consists of tread, 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 tread is made up of steel grating molded by Sinosteel Corporation with good non-skid performance. Contact area employs oil-resistant rubber part to prevent from spark caused by collision.   Features  Full galvanized 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 ‘parked’ position
