Product Description

Manitowoc lattice-boom crawler cranes — including the 3900, 4000, and 4100 series — were used on nuclear-plant construction, refinery erection, bridge builds, industrial-plant work, and heavy structural jobs from the 1950s into the 1980s. According to publicly filed asbestos litigation records, Manitowoc crawler cranes allegedly incorporated chrysotile-asbestos woven brake bands and clutch friction linings on the main hoist, auxiliary hoist, boom hoist, and swing drums. Replacement bands and linings were allegedly supplied through Manitowoc dealer and aftermarket friction channels.

Workers Exposed

Crane operators, oilers, IUOE operating engineers, and dealer/field mechanics allegedly disturbed asbestos brake and clutch dust during band replacement, drum inspection, and compressed-air cleaning of the friction assemblies. Construction laborers and iron workers working alongside crawler cranes on refinery, powerhouse, and industrial jobs allegedly experienced bystander exposure during brake service.
