Heavy Equipment Parts
At Key Parts Company, Inc., we supply a variety of industries with dependable heavy equipment parts and components that keep operations running. The industries we serve include construction, mining, scrap recycling, quarries, demolition, steel mills, and landfills. We organize our inventory by industry so you can source exactly what you need with confidence.
EXPLORE INDUSTRIES WE SERVE
Every industry has unique heavy equipment needs. Our goal is to provide new, good used, and rebuilt components that perform reliably in tough environments, minimize downtime, and keep fleets working.
Excavators, bulldozers, scrapers, wheel loaders, and off-highway trucks must deliver consistent performance on job sites. We supply final drives, transmissions, axles, hydraulic cylinders, undercarriage and other major components that meet OEM standards. Contractors trust our parts to reduce costly downtime and keep projects moving on schedule.
Compactors, dozers, haul trucks, and excavators are essential in landfill operations. We offer final drives, powertrain guards, undercarriage, transmissions, and complete rollouts rebuilt to manufacturer specs and tested. Our solutions help landfill operators reduce downtime and maintain consistent waste management operations.
Mining and quarry operations put extreme stress on machines, and downtime is costly. At Key Parts Co., we supply good/used inspected, rebuilt, new surplus, and aftermarket parts and components — including final drives, wheel groups, differentials, transmissions, and hydraulic cylinders — to keep excavators, haul trucks, loaders, and dozers running strong in tough environments. With properly rebuilt and inspected parts, operations can maintain consistent production and avoid costly interruptions.
(Note: We do not supply breaker parts, crusher liners, or reinforced drive systems — focus is on heavy equipment components.)
Scrap yards and demolition contractors rely heavily on loaders, excavators, and material handlers. We supply tested good used and rebuilt components to keep fleets operational and costs under control. By choosing affordable, reliable alternatives to new parts, scrap recycling and demo operations maintain uptime and profitability.
(Note: We do not supply shredder, conveyor, baler, or sorting equipment parts.)
Steel mills depend on heavy equipment such as wheel loaders, excavators, and material handlers to keep production moving. At Key Parts Co., we supply new, rebuilt, and good used components — including final drives, transmissions, complete rollouts, hydraulic cylinders, and sheet metal — that help mills maximize uptime and keep critical support equipment in operation. By providing reliable alternatives to new OEM-only parts, we help steel mills control costs while keeping fleets working in demanding environments.
