Abstract
Abstract A swimming pool lift installation for the handicapped employs a platform for carrying a wheelchair that is lowered and elevated with the platform so that a handicapped person can sit on his chair and be lowered into the pool for swimming away from the chair and can leave the pool by swimming back into the wheelchair. The chair is releasably secured to the platform so that there is no danger of it being rendered unstable by its buoyancy in the water and so that it can be wheeled on and off the platform. A water hydraulic system operates the lift to avoid contamination of the pool.
