Stable cylinder transport on stairs and uneven surfaces
The POLGAZ I stair climber is a professional welding gas bottle trolley designed for transporting a single technical gas cylinder up to 230 mm in diameter and 1700 mm in height. Thanks to its triple stair-climbing wheel system, it enables convenient and safe cylinder movement not only across flat surfaces but also up and down stairs and over ramps — without effort and without any risk of the load toppling. It is ideal for welding workshops, production plants, technical services, and warehouses where mobility, durability, and operator safety matter.
Construction and safety
The robust frame is manufactured from heavy-wall steel tubing for excellent rigidity and resistance to deformation. The entire structure is powder coated in RAL 5010 (blue) for lasting corrosion protection and a professional appearance. The transport platform is contoured to match the cylinder shape, and a securing chain keeps it firmly in place — even during transport over uneven ground.
Stair-climbing running gear
The defining feature of the POLGAZ I is its stair-climbing wheel assembly with three wheels on each side, manufactured from light-coloured, non-marking rubber. This system allows cylinders to be rolled smoothly up steps without the need to lift them. The trolley maintains full stability throughout, making stair transport significantly faster and safer. The wheels are fitted with roller bearings for quiet operation and long-lasting reliability.
Ergonomics and functionality
Plastic handles protect the operator’s hands from accidental impact with the steel frame. At just 465 mm wide, the POLGAZ I stair climber fits through narrow passages and service lifts with ease.

FAQ
How does the stair-climbing system work? Each side has a set of three wheels mounted on a rotating hub. As the trolley is tilted back and pulled up a staircase, the triple wheel units rotate step by step, maintaining continuous contact with the stair edge for smooth, controlled ascent and descent.
What is the difference between the POLGAZ I stair climber and the BENEK II stair climber? The POLGAZ I is a single-cylinder model — more compact (400×465 mm, 12 kg) and lighter. The BENEK II is a dual-cylinder model (615×610 mm, 24 kg) designed for heavier two-bottle setups. Both share the same triple wheel stair-climbing principle.
Can it fit through narrow doorways and lifts? Yes — at only 465 mm wide, it fits through standard doorways and service lifts without difficulty.
Are the wheels non-marking? Yes — the light-coloured solid rubber leaves no marks on indoor floors, making the trolley suitable for clean workshop and production environments.
