7.2. Connecting to the Vehicle (with air brakes)

The vehicle and trolleys should be placed on track adjacent to one another
with the vehicle parking brake applied.

Flip the trailer brake switch to the air brakes position. The compressor will start
up and the air reservoir will start to fill / top up. Wait until the compressor
switches off (tank is full) as an initial check prior to towing / propelling any
consist. The pressure gauge on the console should reach approximately 8 bar
/ 116 psi.

The trolleys can be manoeuvred by operating the failsafe brake with the
handle supplied. This allows the operator to connect the rigid tow bar between
the vehicle and trolley. Ensure that it is secured with the tow bar pins and
locked in place with the clip pins attached. Note that the R clip needs to be
used when connecting the Personnel Carrier tow bar to the front of the Kubota.

Connect the air brake
“C” couplings on the RRV and trolley using the air
connecting hose. Note that the length of this hose may vary depending on the
consist configuration.

When the hand brake is released, the air will be passed through the air hoses
to release the failsafe brakes on the trolleys within the consist.

Wait until the brakes can be seen to be released before engaging gear and
moving off. When braking to a stop, apply the vehicle brakes gently in good
time before the stopping point is reached.

Harder braking action will release the air pressure holding the trolley brakes off
and they will apply fully in approximately 4-5 seconds. Having stopped, apply
the vehicle handbrake which will maintain the released pressure in the system
and ensure that the trolley brakes are applied.

The tank pressure should be maintained between 6
– 8 bar to ensure that the
5.5
– 6 bar is maintained when braking.

In the event of the trolleys becoming detached from the vehicle the air
connecting hoses will sever and the failsafe trolley brakes will be applied.
7.3. Failsafe Break-away Warning System

The failsafe break-away warning system works through the Marker Light
Board, which is attached to the end of the last trolley in the consist. The
Marker Light Board Cable connects between the Marker Light Board and the
RRV. A connector is fitted to the front and rear of the Permaquip Kubota to
allow connections for towing and propelling. Note that the length of this Cable
may vary depending on the consist configuration. A Dummy Plug is supplied to
allow the Permaquip Kubota to be driven when it is not being used for towing /
propelling.

When swapping the vehicle lights for the Marker Lights, the Control Module
Warning Buzzer will sound to indicate that the lights are disconnected. This will
continue until the trolley Marker Lights are reconnected.
