7. TOWING AND PROPELLING
Ensure that the trolleys that are to be towed / propelled meet the
parameters defined in the Technical Specification.
Refer to the appropriate product User Guides before use (Permaquip
Type B Towing Trolley, Personnel Carrier, Drum Trolley, Rail Mover and
Railman User Guides are supplied with the product but additional copies
are also available on request or can be downloaded from the website).
The following outlines the correct and safe procedures for operation of the
Permaquip Kubota when used for towing / propelling appropriate equipment such as
the Permaquip
™ Type B Towing Trolley, Personnel Carrier, Drum Trolley Rail Mover
and Railman.
7.1. Connecting to the Vehicle (with hydraulic brakes)

The vehicle and trolleys should be placed on track adjacent to one another
with the vehicle parking brake applied and engine turned off.

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.

For trolleys fitted with the active failsafe hydraulically operated break-away
braking system
– simply connect the hydraulic brake connectors on the vehicle
and trolley using the hydraulic connecting hose. Note that the length of this
hose may vary depending on the consist configuration.

When the vehicle is restarted and the hand brake released, the hydraulic
system will pump the brake operating cylinders on the trolleys.
Note that this connecting hose cannot be released when there is sufficient
pressure within the system to hold the failsafe brakes in the ‘off’ position.

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 hydraulic pressure holding the trolley
brakes off and they will apply fully in approximately 4-5 seconds. Having
stopped, apply the vehicle handbrake which will then release the pressure in
the system and ensure that the trolley brakes are applied.

In the event of the trolleys becoming detached from the vehicle the hydraulic
connecting hoses will sever and the trolley brakes will be applied.
