Mining & Quarries
Parts in Hand Fast
Stop Downtime. Keep Production Moving.
Mining and quarry environments are some of the toughest applications for heavy equipment. When a machine goes down on the bench or at the crusher, everything behind it stops—trucks
sit, material doesn’t move, and production takes a hit immediately.
At Key Parts Company, Inc., we supply rebuilt, good used, new surplus, and aftermarket mining and quarry equipment parts to keep your operation running. Whether it’s a failed transmission,
worn-out component, or a cylinder that won’t hold, we help you get back up and running—fast and affordably.

Mining & Quarry Equipment We Support
We don’t just supply parts—we understand the machines, the applications, and where they fail in high-production environments.
We Support
Excavators
Excavator Parts
Excavators in quarry and mining applications run constant cycles moving heavy material. That workload puts serious stress on hydraulics, structures, and undercarriage components. When one goes down, it affects everything downstream.
We supply:
- Hydraulic Cylinders & Pumps – Rebuilt, tested, and ready to install
- Buckets, Pins & Bushings – High-wear components built for abrasive environments
- Booms & Sticks – Good used, low-hour takeoffs, and rebuilt options
- Undercarriage Components – Rails, rollers, idlers, and sprockets
- Sheet Metal – Doors, panels, and guards to keep machines safe and operational
- Final Drives – Rebuilt, aftermarket, and good/used options
- Seats – New “same as OEM” replacements matched to machine model and serial number
Wheel Loaders
Wheel Loader & Aggregate Equipment Parts
Wheel loaders keep material moving—feeding crushers, managing stockpiles, and supporting daily production. When one goes down, operations back up fast.
We provide:
- Booms & Linkage Components – Built for constant cycling under heavy loads
- Hydraulic Cylinders – Rebuilt and pressure-tested
- Transmissions & Torque Converters – Rebuilt to manufacturer spec
- Complete Axles & Differentials – Ready-to-install assemblies
- Final Drives – Rebuilt and tested
- Buckets – Built to handle abrasive material and maintain production
- Sheet Metal, Guards & Protective Components – Keep debris out of critical systems
Articulated Dump Trucks
Articulated Dump Truck Parts
Articulated trucks are constantly moving material across rough ground under load. That kind of work wears down drivetrains, suspension, and hydraulic systems fast. When one goes down, your haul cycle slows immediately.
We supply:
- Transmission and Torque Converters: – Rebuilt and ready for heavy haul cycles
- Differentials & Drivetrain Components – Built for constant load
- Complete Axles – Rebuilt and ready to install
- Hydraulic Cylinders – Dump and steering cylinders rebuilt and tested
- Suspension Components – A-frames, bushings, and supports
- Brake Systems – Brake packs, calipers, and parking brake components
- Final Drives – Rebuilt and tested
Rigid Haul Trucks
Rigid Frame Truck Parts
Rigid haul trucks carry full loads across rough terrain all day. That puts constant stress on transmissions, suspension systems, and drivetrains. When a truck is down, material doesn’t move—and production slows immediately.
We supply:
- Transmissions & Torque Converters – Rebuilt and dyno-tested
- Differentials & Drivetrain Components – Built for heavy haul cycles
- Complete Axles – Rebuilt and ready
- Hydraulic Cylinders – Hoist and lift cylinders rebuilt and ready
- Suspension Components – Struts, A-frames, and supports
- Sheet Metal – Doors, hoods, guards, and cabs
- Tanks – Fuel and hydraulic tanks, reconditioned and ready
- Final Drives – Rebuilt and tested for continuous operation
Dozers
Dozer Parts
Dozers take constant abuse pushing material, maintaining roads, and working in rough conditions. Undercarriage and powertrain failures are common and costly.
We supply:
- Undercarriage Components – Rails, pads, rollers, idlers, and sprockets
- Transmissions & Torque Components – Rebuilt and tested
- Final Drives & Differentials – Built for continuous pushing
- Blades & Cutting Edges – Wear parts ready for the job
- Hydraulic Cylinders – Rebuilt and ready to install
- Guards & Structural Components – Protection for harsh environments
Motor Graders
Motor Grader Parts
Graders are critical for maintaining haul roads. If roads go bad, everything slows down—cycle times increase and wear on equipment goes up.
We supply:
- Circle & Blade Components – Built for continuous grading
- Hydraulic Cylinders – Rebuilt and tested
- Transmissions & Drivetrain Components – Ready for install
- Tandem Drives & Differentials – Rebuilt assemblies
- Cabs, Controls & Electrical Components – Keep operators productive
Support Equipment
Support Equipment & Attachments
Support equipment keeps operations moving and handles the jobs larger machines can’t.
We supply:
- Skid Steer & Backhoe Parts – Hydraulic, drivetrain, and structural components
- Buckets & Attachments – General purpose, heavy-duty, and specialty buckets
- Forks & Material Handling Attachments – Built for daily use
- Machine-Mounted Hammers – New, rebuilt, and replacement components
- Quick Couplers & Mounting Systems – Improve efficiency on-site
Parts & Rebuild Solutions for Mining and Quarry Heavy Equipment
Quarry and mining heavy equipment wear faster—abrasive material, long hours, and heavy loads push
components to failure quickly. We focus on getting you back up without OEM delays or pricing.
We Supply:
- Transmissions & Torque Converters – Tested and built for production work
- Complete Rollouts, Differentials & Drivetrain Components – Ready-to-install assemblies
- Final Drives – Rebuilt and tested
- Hydraulic Cylinders – Rebuilt, pressure-tested, and ready to install
- Hydraulic Pumps – Rebuilt and calibrated for performance
- Brake Packs, Calipers & Parking Brakes – Complete braking solutions
- Sheet Metal – Doors, guards, panels, and protective components
