LHD Parts: Clarifying the Term Before Going Further
In mining supply and procurement, LHD means one thing: load-haul-dump. It is the underground mining loader that scoops blasted material from a stope, carries it through decline headings, and tips it at a drawpoint or into an underground truck. Every reference to LHD parts, underground LHD spare parts, and load haul dump components on this page refers exclusively to that machine and its underground mining application, not left-hand drive vehicles, which share the same abbreviation in general search results but have no relevance here.
Why the LHD Is the Underground Mine's Most Critical Mobile Asset
In an underground hard rock mine, production starts and ends with the load-haul-dump machine. Blasting opens the stope, but blasted ore sitting in a confined underground void produces nothing until an LHD moves it. Every haul truck at the drawpoint, every tonne processed at the surface crusher, every shift target on the mine plan depends on that LHD completing its mucking cycle without interruption.
That dependency is what makes underground mining loader parts a production-critical sourcing requirement rather than a routine maintenance function. When an LHD goes down in a stope, the options for working around it are limited by the heading geometry; another machine cannot simply be repositioned from surface or from a nearby level without planning, logistics, and time that the production schedule does not easily absorb.
Underground Loader Parts by Brand and Model
Sandvik Underground Loader Parts
Sandvik is the dominant manufacturer in the underground LHD market, and the Sandvik LH series covers the full capacity range deployed across global underground hard rock mining. Three widely operated platforms are catalogued at Imara Engineering:
-
Sandvik LH307 parts — the LH307 is a 7-tonne capacity underground loader suited to narrower stopes and tighter heading profiles. Drivetrain, hydraulic, and bucket system components are catalogued as LH307-specific references.
-
Sandvik LH410 parts — the LH410 carries a 10-tonne bucket payload and represents the mid-range of Sandvik's LHD lineup, with updated hydraulic and driveline specifications from the LH30..7
-
Sandvik LH514 parts — the LH514 is a 14-tonne capacity loader deployed in larger stope configurations and high-production underground operations, with distinct structural and powertrain specifications from the lighter LH platform
Both OEM-quality and aftermarket Sandvik underground loader parts are available, with every order confirmed to a specific model and serial number before dispatch.
Epiroc Underground Loader Parts
Epiroc's ST-series underground loaders carry a strong operational presence across global underground mining, and Epiroc underground loader parts at Imara Engineering are catalogued across three widely deployed platforms:
-
Epiroc ST14 parts — 14-tonne capacity underground LHD with hydraulic and drivetrain components specific to the ST14 platform
-
Epiroc ST18 parts — the ST18 steps into the higher capacity range with updated structural and powertrain specifications
-
Epiroc ST1030 parts — one of Epiroc's largest underground loaders, carrying a 30-tonne bucket payload in large-cross-section stope configurations. Component specifications across the ST1030's driveline and hydraulic system are specific to this platform and require dedicated cataloguing.
CAT Underground Loader Parts
CAT's underground hard rock loader range brings the CAT engineering standard to LHD applications, and CAT underground loader parts at Imara Engineering cover two widely operated R-series platforms:
-
Cat R1300 underground loader parts — CAT's mid-range underground loader, with drivetrain, hydraulic, and bucket system components catalogued as R1300-specific references
-
Cat R1700 underground loader parts — the R1700 carries a higher bucket payload than the R1300, with distinct structural and powertrain specifications. The R1700 is one of the most productive underground LHD platforms in the CAT range, and its maintenance requirement reflects the intensity of high-cycle underground loading.
Normet Underground Loader Parts
Normet occupies a specialist position in the underground mining equipment market, as a manufacturer whose product range is built entirely around underground mining applications. Normet underground loader parts at Imara Engineering cover the Normet underground LHD range, with component sourcing available across drivetrain, hydraulic, and structural systems. Contact Imara Engineering directly for model identification and parts availability confirmation on Normet platforms.
Load Haul Dump Components: The Systems That Matter Most
Underground LHD maintenance concentrates on the systems that absorb the highest operational stress across the mucking cycle:
-
Bucket and attachment — bucket teeth, adaptors, cutting edges, and wear plates are the highest-frequency replacement items across every LHD in operation
-
Articulation joint — centre joint pins, bushings, and bearing assemblies carry a continuous load with every steering movement underground.
-
Hydraulic system — lift and tilt cylinder assemblies, hydraulic pump components, and circuit sealing hardware
-
Drivetrain and transmission — torque converter assemblies, differential components, and final drive hardware across both diesel and electric drive configurations
-
Tyres and rims — underground haul road surfaces generate consistent tyre wear, and tyre replacement is a high-frequency maintenance event on any active LHD fleet
-
Engine and cooling — engine components and cooling system hardware cross-referenced to each platform's specific configuration and underground emission requirements.
