ROPE SHOVELS
Built to support critical rope shovel systems

OVERVIEW

Boundary supports CAT and Komatsu/P&H rope shovels with aftermarket components, rebuilds, and maintenance solutions across undercarriage, dipper and door hardware, front-end components, and gearcases and transmissions. Since 1980, our rope shovel offering has been built around OEM-compatible fit, timely supply of critical components, and practical improvements to known wear points, not just part replacement.
UNDERCARRIAGE

Undercarriage components built for OEM-compatible fit and long wear life. Boundary supports track shoes, front idlers, rollers, drive tumblers, sliders, pins and bushings, pillow blocks, and Posikeeper pin retention. With model-specific improvements such as proprietary manganese track shoes, bolt-on slider systems, forged and induction-hardened rolling components, and replaceable-lug tumblers on supported applications
FRONT-END, DIPPER DOOR & TRIP COMPONENTS

Front-end, dipper door, and trip components that keep rope shovels working. Boundary supports point sheaves, latch bars, latch levers, padlocks, pitch braces, hydraulic snubbers, crowd take-up assemblies, dipper trip assemblies, racking, and related hardware. Our offering includes new hydraulic snubbers for CAT 7495 and P&H 4100 dipper doors, built to OEM-compatible fit and wear life.
GEARCASES & TRANSMISSIONS

Gearcases, transmissions, pump drives, and new ZF gearbox supply backed by rebuild experience dating to 1965. As the official Canadian dealer for ZF, Boundary supports swing, propel, hoist, and related drive systems with both rebuilt units and new gearbox supply for mining customers across Canada.
MAINTENANCE & ACCESS SOLUTIONS

Maintenance and access solutions designed to make rope shovel work safer and easier. Boundary supports products such as track pin pullers, lube booms, boarding ladders, slider handling tools, lower roller installation jigs, and related maintenance aids built to reduce handling risk and improve control during planned work.
FIELD SUPPORT

Support does not end when the component is installed. Boundary works with customers through inspection, wear feedback, and rebuild follow-up to help improve service life, refine future component supply, and support better maintenance outcomes on the machine.
