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 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 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 spark caused by collision. Maximum design load is more than 300kg. Folding Stairs Features Fully balanced self-leveling steps to automatically adjust to varying tanker heights Full galvanized treatment, anti-corrosion, rust-proof and durable. Safety handrails and knee guards fitted as standard Hinged safety step to protect against accidentally trapping toes Pull-rope to assist returning stairs to ‘parked’ position Vertical locking device (optionally offset) for ‘parked’ position with foot-pedal release Extended outboard step to provide additional area and stability, for stepping onto the tanker top Rubber bumper to prevent sparking and reduce risk of tanker damage Applications Safe access from fixed platforms to the top of a Road Tanker, Rail Tank Wagon, or ISO Container to: Inspect the tanker for safety and maintenance Load the tanker Check the load and take sam
