LED Lighting & Electrical

LED sealed beam wiring system with stop / turn/ tail lights recessed in a structural tubing bumper to meet FMVSS 108 ensure long life of these signaling lights.  Automotive-grade wiring harness features SAE bullet-style connectors at each light, ensure easy replaceability of individual lights.  SAE 7-way socket protected top sides and back with almag housing.  Sealed breakaway with charging circuit and LED battery condition indicator with 450 C.C.A. maintenance-free battery.  Recessed ABS license plate housing with integrated lamp provide very high protection of both the license plate and its illumination.

Wheel Nut Indicators

Our wheel nuts are torqued to manufacturer specifications, and are then fitted with high-visibility wheel nut indicators. The indicators are fitted in a uniform pattern, so when a wheel nut has loosened, the indicator will become out of sequence. The wheel nut indicators are also heat sensitive. If there is a binding brake or seized bearing, the heat is transferred through the stud and nut. If this temperature exceeds 120º C (248º F), the indicator will start to blister around the circumference and eventually start to distort. Pre-flight walkaround checks now can include wheel nut checks.

Solar Power

We include our Model 8854 Solar System with a single solar panel with 4.3W of charging as standard equipment on all trailers we manufacture that utilize electric brakes or are equipped with an electric start Hydraulic Power Source. We have made this improvement to reduce customer maintenance costs, increase “up time” in field operations and provide the highest assurance to your users and community that the system will work as designed in the event the of a breakaway.
