Garaventa Lift is an international company specializing in the manufacturing of home elevators, compact commercial elevators and accessibility products. A world leader in the industry with a reputation for quality and reliability, Garaventa Lift has over 50,000 installations worldwide and many innovative products.
The GSL Artira Stair-Lift was the first inclined platform wheelchair lift in North America capable of travel along straight or curving stairways, up several flights of stairs and across horizontal landings. The GSL Artira's computer based control system and Smart-Lite technology make it the easiest lift on the market to use.
The XPRESS II Stair-Lift is a platform wheelchair lift designed for straight stairways with two landings. It is ideal for heavy-duty commercial applications as it utilizes mains power for the drive motor. The XPRESS II can be installed with little or no structural modifications.
The X3 is the newest addition to the Garaventa product line. The X3 inclined wheelchair lift has been designed for residential or commercial use. The design allows for fast delivery and installation. The drive motor utilizes rechargeable battery power.
