Parts Portal specialises in heavy machinery electrics across mining, earthmoving, industrial, and agricultural equipment. We supply both custom-built and documented replacement harnesses for brands including CAT, Komatsu, Hitachi, Liebherr, Sandvik and more.
You can browse our brand we stock without an account, but a B2B login is required to view the full product range, pricing, place orders, and access trade benefits such as bulk rates, saved harness history, and priority support. Creating an account is free and takes less than two minutes.
We do both. Parts Portal stocks thousands of electrical components, connectors, plugs, tools, and factory-spec harnesses. We also manufacture custom wiring looms and electrical overhaul solutions in-house. This includes reverse-engineering harnesses, building new systems to OEM standard, and supplying full electrical rebuilds for machine life extension.
