Forestry machines operate in some of the toughest conditions in the world. From tree harvesters and feller bunchers to mulchers for grass and undergrowth, wood processors and sawmills, and forwarders or loaders that transport heavy logs, each machine relies on a robust electrical architecture to function safely and efficiently. At the core of this architecture is the wire harness, connecting and powering the vehicle’s sensors, actuators, control panels, lighting systems, hydraulic units, and auxiliary tools.
Materials & Components
OEM S.r.l. develops tailor-made harnesses for forestry machinery using components designed to endure mechanical stress, outdoor exposure, and constant vibration:
- Cables with reinforced insulation (PVC, PUR, XLPE) resistant to oil, mud, abrasion, and UV, yet flexible enough for dynamic movement.
- Connectors with IP67/IP69K sealing, suitable for pressure washing and continuous exposure to water, dirt, and wood dust.
- Protective elements such as braided sleeves, corrugated conduits, and heat-shrink tubing for resistance against cuts and impacts.
- Mounting accessories engineered to relieve stress and ensure secure routing in moving machine parts.
- Integration of control and sensing elements, such as hydraulic valve controllers, angle and pressure sensors, load monitoring, and camera systems.
Manufacturing Procedures & Techniques
OEM S.r.l. integrates automated processes with skilled manual assembly, ensuring repeatability, flexibility, and reliability:
- Automated cutting, stripping, and labeling of cables for precise and traceable preparation.
- Terminal crimping and ultrasonic welding, verified through pull-force tests and micro-section analysis.
- Shielded cabling for signal lines to prevent electromagnetic interference in complex electronic systems.
- Overmolding and sealing to guarantee long-term reliability of connectors exposed to mud and weather.
- Flexible bundling and routing techniques, optimized for repetitive cycles of forestry equipment.
Wire harnesses for forestry machines can be configured for:
- Tree cutting and processing machines (harvesters, sawmills, processors).
- Grass and mulching machines for clearing vegetation.
- Transport and loading machines (forwarders, skidders, cranes, loaders).
- Lighting, camera, and operator control systems for safety and visibility.
- Hydraulic and powertrain circuits, including sensors and actuators.
