Construction Equipment
Wire Harnesses
Wiringo is a trusted manufacturer and assembler of wire harnesses for construction equipment, from small machines like welders to large machinery such as cranes and excavators.
Our Clients
Construction machinery operates in harsh environments, where dust, moisture, extreme temperatures, corrosion, and constant vibration are common. Wire harnesses in these machines must endure repeated exposure to these conditions to ensure reliable performance.
Products
Wiringo offers a full range of wiring harnesses built for construction equipment.

Main Equipment Wiring Harnesses
These are the core harnesses that form the central nervous system in construction equipment. They interconnect various circuits and components in the machines.

Battery Wiring Harnesses
These wiring harnesses connect the battery to various equipment components to supply power. In fully electric machines, such as forklifts, these harnesses are thick, low-gauge types to handle high current loads from the battery pack to motors and hydraulic lift pumps.

Engine Wiring Harnesses
Like in cars, engine wiring harnesses connect actuators, sensors, and other electronic components around and inside the engine to the ECU for data processing and control.

Cabin Wiring Harnesses
Cabin wiring harnesses provide power to the operator controls, gauges, switches, and other cabin control systems while capturing signals from these components, including pedals, as the operator runs the machine.

Sensor Wiring Harnesses
Construction equipment needs multiple sensors to capture real-time data about load and safety parameters, and all these connect to the relevant modules via wires.

Lighting Wiring Harnesses
Construction equipment uses lighting to enhance visibility, productivity, and safety for operators and workers at work sites. Lighting wiring harnesses power various onboard lights, such as cabin, front, and rear, to enhance these functions.
Customization Options
Wiringo understands that there is no one-size-fits-all solution. We focus on gathering detailed information about each customer’s needs to define the exact cable assembly specifications. Harness design is shaped by equipment function and complexity, and can be customized in a variety of ways, including:
| Length and layout | Tailored to specific challenges | |
| Wires and cables | Insulation material |
|
| Flexible conductors |
|
|
| Connectors | Heavy-duty industrial connectors | Sealed, Weatherproof, High-Current, Modular |
| Features |
|
|
| Tests | Meet and exceed the requirements | |
Industry Applications
Some areas where our construction equipment wiring harnesses can be used include:
Excavator
Cable assemblies in excavators facilitate communication between control units, hydraulic systems, and sensors, gathering data for precise control and operation.
Bulldozer
Wiring harnesses play a critical role in bulldozers. They link the engine controls and power systems, ensuring efficient and responsive operational control and power distribution.
Forklift
Forklifts, especially electric ones, need reliable wiring harnesses to provide power and communication between the battery management systems, charging systems, control units, motors, hydraulic lifts, and other onboard components.
Loader
Wiring harnesses in loaders provide the electrical connections needed for monitoring onboard systems, sensors, instrumentation, and hydraulic controls.
Crane
Wiring harnesses inside cranes must reliably integrate load monitoring sensors, safety sensors, and other control systems.
Dump Truck
Our wiring harnesses are robust enough to support the trailer control, engine management, and braking system to enable safe transportation.

Frequently Asked Questions
Which testing procedures do you use to ensure products meet the required performance, reliability, and safety standards?
Each construction equipment wiring harness undergoes pull tests, environmental resistance tests, insulation resistance tests, and load tests to ensure it meets industry standards and performs reliably in the harsh construction environment.
How do your wiring harnesses enhance signal integrity in noisy construction environments?
We employ techniques like twisting wire pairs and shielding to ensure reliable signal transmission in areas with high EMI. These are coupled with shielded connectors to secure the signal to its destination.
Can your construction equipment wiring harnesses integrate with modern electronic control systems?
Yes. These wiring harnesses support advanced communication protocols like LIN and CAN bus to enable communication with advanced electronic control systems or ECUs. This allows you to monitor several parameters and control various functions efficiently.
