Garaventa Lift is an international company specializing in the manufacturing of accessibility products. A world leader in the accessibility industry with a reputation for quality and reliability, Garaventa Lift has over 15,000 installations worldwide and many innovative products.

The GSL Artira Stair-Lift was the first inclined platform wheelchair lift in North America able to travel along straight or curving stairways, up several flights of stairs and across horizontal landings. The GSL Artira's computer based control system makes it the easiest lift on the market to use. The GSL Artira can travel on the inside or outside radius of the stairway, offering the optimum in design flexibility.

The XPRESS II Stair-Lift is a platform wheelchair lift designed for straight stairways with two landings. The unique design of this lift makes it very cost-effective with short delivery and installations times. For design versatility, the XPRESS II can be mounted on either side of the stairway depending on the stairway design and location. The XPRESS II can be installed with little or no structural modifications.

Both lift types are available in a variety of platform sizes for interior or exterior applications, can be custom powder coated in any RAL color and are ADA and elevator code compliant.
