Off-highway harnesses have the hardest life in the industry. Our answer is physical: heavier gauge where flexing happens, full conduit coverage rather than partial, and sealed connectors at every exposed interface.
Typical applications
Excavator, loader and dozer main harnesses
Hydraulic control and solenoid valve harnesses
Cab, dashboard and joystick sub-harnesses
Engine and after-treatment sensor harnesses

Questions on this family
Do you build battery and starter cables for heavy equipment?
Yes. Heavy-gauge battery, starter and ground cables with compression lugs and sealed terminations are quoted as part of the machinery harness programme.
Can harnesses be built for field service replacement?
Yes. We build service-part harnesses on lower volumes, with field-repairable terminations where the maintenance team prefers them.
Certificate scope: our IATF 16949:2016 certificate covers manufacturing of wire harness and excludes product design under Clause 8.3. Specifications shown are the range we manufacture, not a warranty of suitability for a specific application.
Send us what you have. We will tell you what is possible.
A drawing, a sample, a connector list or a photo is enough to start. Typical reply within one working day, with engineering questions rather than a sales pitch.
