Product Description
Westinghouse Elevator, the elevator division of Westinghouse Electric Corporation, was for decades one of the principal American elevator suppliers alongside Otis. Westinghouse Elevator built geared traction hoist machines for freight and mid-rise passenger elevators, gearless machines for high-rise passenger service, and the associated control gear, hoistway hardware, and brakes. The division was acquired by Schindler in 1989.
Plaintiffs alleged in publicly filed U.S. asbestos personal-injury and wrongful-death litigation that Westinghouse Elevator specified asbestos-fabric and molded asbestos-composition friction linings for its hoist-machine brake shoes during the decades when asbestos was the industry-standard elevator brake material. The brake shoes bore on the hoist-machine drum or disc and were the primary means of holding the car at floor and arresting motion — a duty cycle that generated significant heat and friction dust during normal service.
Asbestos Content
Plaintiffs alleged that Westinghouse Elevator hoist-machine brakes contained asbestos in the following roles:
- Woven asbestos brake fabric — riveted to steel shoes on drum-type brakes.
- Molded asbestos-composition friction blocks — used on later disc-brake designs on gearless machines.
- Brake dust residue — deposited on machine-room floors, brake covers, and adjacent equipment by normal wear.
- Replacement friction parts — plaintiffs alleged that Westinghouse service literature specified asbestos-bearing linings for scheduled relining work.
Workers Exposed
- Elevator constructors (IUEC) — new-installation brake work and modernization relining in office towers, hospitals, and industrial buildings.
- Elevator mechanics and adjusters — periodic brake adjustment, dust cleaning, and shoe replacement.
- Industrial mechanics and millwrights — freight-elevator brake service in factories, warehouses, and mills.
- Building maintenance mechanics — supporting elevator brake service in commercial buildings.
- Bystanders — building engineers, electricians, and mechanical-room staff sharing enclosed machine rooms during brake work.
Take-home exposure was alleged where workers carried asbestos fibers home on work clothing.
