PLST Mechanical System.

The drawbar (Figure 2, Item 3) provides a means to tow, steer, and adjust the length of the trailer. The turntable

(Figure 2, Item 2) allows the front axle to turn on axis to provide steering. The main frame (Figure 2, Item 1) provides

a mounting place for the rest of the systems. Three spring-mounted axles (Figure 2, Item 5) provide a cushioned

ride for loads. Spring-operated parking brakes (Figure 2, Item 6) provide safe parking without air pressure. During

operation, service brakes provide braking power. Safety chains (Figure 2, Item 4) on the drawbar attach to the tow

vehicle as a safety backup. Load locks (Figure 2, Item 7) provide the means to lock the flatrack to the trailer for

transport.

PLST ELECTRICAL SYSTEM

PLST Electrical System.

The intervehicular power hookups (Figure 3, Item 7) (12V and 24V power hookups) allow the operator to hook up

the trailer to the towing vehicle in either 12 or 24 volt mode. Wire harnesses (Figure 3, Item 4) route electrical power

between electrical components of trailer. The rear combination light (Figure 3, Item 8) provides blackout marker,

stop, and signaling capability. The front junction box (Figure 3, Item 6) provides a way of routing electrical harnesses

and connecting trailer intervehicular wiring harness to prime the mover. The rear junction box (Figure 3, Item 1)

provides a way of routing electrical harnesses to rear of trailer. Front and rear marker lights (Figure 3, Item 5) provide

safe side and rear markers for the trailer and allow the operator to observe the trailer during limited visibility. The

load-lock sensor (Figure 3, Item 3) sends a signal to the vehicle indicating if load-locks are locked. The load-lock

sensor power cable (Figure 3, Item 2) connects the trailer load lock sensor to the vehicle.
