Allis-Chalmers Manufacturing Co. — Asbestos Product Reference

Headquarters: West Allis, Wisconsin Founded: 1901 Ceased Asbestos Use: approximately 1980 Product Categories: Turbines, Boilers, Pumps


Company History

Allis-Chalmers Manufacturing Co. was incorporated in 1901 following the consolidation of several established Midwestern industrial firms, including Edward P. Allis Co., Fraser & Chalmers, Gates Iron Works, and the Dickson Manufacturing Co. Operating from its principal manufacturing complex in West Allis, Wisconsin, the company grew into one of the largest and most diversified heavy industrial equipment manufacturers in the United States.

Throughout the first half of the twentieth century, Allis-Chalmers supplied critical machinery to American power generation, mining, agriculture, petrochemical refining, and manufacturing industries. Its engineering divisions produced steam turbines capable of generating hundreds of megawatts of electrical power, large-scale centrifugal and reciprocating pumps for industrial fluid handling, and boilers and pressure vessels for utility and industrial service. The company’s equipment was installed in power plants, shipyards, refineries, paper mills, chemical facilities, and manufacturing plants across the country.

At the height of its industrial operations, Allis-Chalmers employed tens of thousands of workers and maintained a substantial engineering and service organization that supported installed equipment through on-site maintenance, rebuilding, and overhaul programs. The company’s reach extended well beyond initial manufacturing: service engineers and field technicians routinely traveled to job sites where Allis-Chalmers machinery had been installed, often working alongside the tradespeople — pipefitters, millwrights, boilermakers, insulation workers — who maintained that equipment over decades.

Allis-Chalmers experienced significant financial difficulties beginning in the 1970s, ultimately filing for Chapter 11 bankruptcy in 1987. Its various divisions were reorganized or sold to successor companies over subsequent years. The company does not operate a formal asbestos personal injury trust fund, and claims arising from alleged asbestos exposure associated with Allis-Chalmers products are pursued through civil litigation against successor entities and related parties.


Asbestos-Containing Products

According to asbestos litigation records, Allis-Chalmers incorporated asbestos-containing materials into several categories of industrial equipment manufactured and sold from the 1920s through approximately 1980.

Steam Turbines (Industrial and Utility Grade, 1920s–1980)

Allis-Chalmers steam turbines were among the company’s most significant product lines, supplied to electric utilities, naval shipyards, and heavy industrial facilities nationwide. The Powerhouse Database NAMERICA records 956 Allis-Chalmers turbines installed across U.S. power plants, underscoring the breadth of the company’s market presence in this category. Plaintiffs alleged that asbestos-containing insulation was applied to turbine casings, steam inlet and exhaust lines, and associated piping systems, and that asbestos-containing gaskets and packing materials were specified for use in turbine valve assemblies and flange connections. Court filings document claims that Allis-Chalmers service and installation manuals directed maintenance personnel to use asbestos-based materials during routine overhaul and re-packing procedures.

Centrifugal and Reciprocating Pumps

Allis-Chalmers manufactured a broad range of centrifugal and reciprocating pumps for industrial fluid-handling applications, including high-temperature and high-pressure service environments. According to asbestos litigation records, these pumps incorporated asbestos-containing packing in their stuffing boxes and asbestos-based gaskets at flange connections and valve bodies. Plaintiffs alleged that replacement packing and gasket materials specified in Allis-Chalmers maintenance documentation were asbestos-containing, and that workers performing routine repacking and seal replacement operations were exposed to airborne asbestos fibers generated during those procedures.

Boilers and Pressure Vessels

Court filings document claims that Allis-Chalmers boilers and pressure vessels were manufactured with asbestos-containing insulation applied to exterior surfaces and that internal sealing components — including door gaskets, manhole cover gaskets, and hand hole fittings — incorporated asbestos materials. Plaintiffs alleged that boiler tube replacement, refractory repair, and inspection activities created conditions under which asbestos fibers became airborne, affecting both plant workers and Allis-Chalmers service technicians performing warranty and contract maintenance work.

Condensers and Heat Exchangers

According to asbestos litigation records, Allis-Chalmers condensers and heat exchangers used in power generation and industrial process applications incorporated asbestos-containing gasket sheet material at tube sheet flanges and water box covers. Plaintiffs alleged that teardown and reassembly of these units during scheduled maintenance outages required the removal and replacement of deteriorated asbestos gasket material, generating fiber release in enclosed or semi-enclosed spaces.


Occupational Exposure

Workers across a wide range of trades and job classifications encountered Allis-Chalmers equipment in settings where asbestos-containing components were present. According to asbestos litigation records, the following occupations and industries are most frequently referenced in claims involving Allis-Chalmers machinery:

Power Plant Workers. Utility boilermakers, turbine operators, and maintenance millwrights who worked in coal-fired, oil-fired, and nuclear power plants where Allis-Chalmers turbines and boilers were installed. Plaintiffs alleged that scheduled maintenance outages required hands-on work with insulated turbine casings, steam lines, and gasketed pressure components, often in proximity to other trades simultaneously performing work that disturbed asbestos-containing materials.

Pipefitters and Steamfitters. Tradespeople responsible for connecting and maintaining the steam and condensate piping systems associated with Allis-Chalmers turbine and boiler installations. Court filings document claims that these workers regularly cut, fit, and handled asbestos-containing pipe insulation and replaced asbestos gaskets and valve packing as part of routine maintenance activities.

Boilermakers. Workers who performed refractory and insulation work on Allis-Chalmers boilers and pressure vessels, including removal of degraded asbestos-containing boiler insulation and gasket material during tube replacement and inspection procedures.

Insulation Workers (Insulators). Plaintiffs alleged that insulators who applied or removed thermal insulation from Allis-Chalmers turbines, boilers, and associated piping were exposed to asbestos-containing insulation products, including blanket, block, and spray-applied materials commonly used in power plant and industrial settings during the mid-twentieth century.

Shipyard Workers. Allis-Chalmers supplied marine steam turbines and auxiliary equipment to U.S. Navy and commercial shipbuilding programs. Court filings document claims from shipyard machinists, pipefitters, and boilermakers who worked in close quarters with Allis-Chalmers machinery during ship construction and repair operations — conditions that plaintiffs alleged concentrated airborne asbestos fiber exposure.

Petrochemical and Refinery Workers. Workers at petroleum refineries and chemical processing plants where Allis-Chalmers pumps, compressors, and heat exchangers were in service. Plaintiffs alleged that routine pump repacking and gasket replacement operations contributed to cumulative asbestos exposure over the course of long careers in these industries.

Allis-Chalmers Field Service Technicians. According to asbestos litigation records, the company’s own service engineers and field representatives who traveled to customer sites to perform installation, commissioning, and contract maintenance work on Allis-Chalmers equipment were also included among alleged exposure populations.

It is important to note that asbestos disease typically has a latency period of 20 to 50 years between first exposure and diagnosis. Workers whose careers included contact with Allis-Chalmers equipment during the mid-twentieth century may be receiving diagnoses of mesothelioma, lung cancer, asbestosis, or pleural disease today.


Allis-Chalmers Manufacturing Co. does not maintain a dedicated asbestos personal injury trust fund. The company filed for Chapter 11 bankruptcy protection in 1987, and its assets were subsequently reorganized and sold to various successor entities. Unlike some bankrupt asbestos defendants that emerged from reorganization with a Section 524(g) trust funded to compensate future claimants, Allis-Chalmers did not establish such a mechanism.

Claims involving alleged asbestos exposure from Allis-Chalmers products are currently pursued through civil litigation. Court filings document ongoing asbestos personal injury lawsuits naming successor entities and, in many cases, co-defendants — including manufacturers of insulation, gasket products, and packing materials that were specified for use with Allis-Chalmers equipment or applied to it by contractors and maintenance personnel.

Because Allis-Chalmers equipment was typically installed alongside products from multiple manufacturers, individuals diagnosed with mesothelioma or other asbestos-related diseases after working in or around Allis-Chalmers machinery may have claims against several parties simultaneously. In many such cases, compensation is available through a combination of civil lawsuit judgments or settlements and claims filed against the asbestos trust funds of other product manufacturers whose materials were present at the same job sites.


Plain-Language Summary

If you or a family member worked with or around Allis-Chalmers turbines, boilers, pumps, condensers, or heat exchangers — particularly in power plants, refineries, shipyards, or industrial facilities — and have been diagnosed with mesothelioma, lung cancer, asbestosis, or a related condition, you may have legal options. Because Allis-Chalmers does not have a trust fund, pursuing compensation typically involves civil litigation against successor companies and, in many cases, filing claims against the asbestos trusts of other manufacturers whose products were used alongside or on Allis-Chalmers equipment. An attorney experienced in asbestos litigation can review your work history to identify which defendants and trust funds may apply to your specific situation. There are time limits on filing — known as statutes of limitations — so it is important to seek a legal consultation promptly following diagnosis.
