Brakes; Emergency Towing; Parking The Machine - McConnel ROBOCUT RC28 Operator's Manual

BRAKES

Machine movement is controlled by electric track motors which drive the machine when
they receive electrical power from the generator, motion is stopped by 'short-circuiting' the
motors which generates a braking effect to halt the machine.
If the engine is switched off, or cuts-out for any reason, the motors 'lock-out' to hold the
machine; if the machine is facing up or down a slope it may not bring the machine to a
complete standstill but it will greatly reduce roll-away speed allowing the machine to
'creep' safely to the bottom of the gradient.
It is important that the machine is never parked-up or left unattended a slope, if the
machine needs to be stopped on a slope for any reason it should be positioned across the
gradient, and if necessary chocked front and rear to ensure it cannot move under its own
weight.

Emergency Towing

In a recovery situation that necessitates the machine being towed by another vehicle, the
three power cables to each track motor must first be disconnected.
Location of track motor power cables: the 3 power cables on each motor must be disconnected for towing.
Towing of the machine should only be performed in an emergency situation. A rigid towing
bar or frame should be used connected to lift point(s) on the front of the machine; never
use chains or ropes to tow the machine.
If it is deemed necessary to tow the machine, the distance towed and the towing speed
should be kept to an absolute minimum.

Parking the Machine

When not in use the machine must always be parked on a firm level site with the main
power switched off. When leaving the machine unattended or for long-term storage the
machine should be chocked front and rear to avoid risk of accidental movement.
The remote control unit should be stored in a different location to protect the machine from
use by unauthorised persons.
Never stand, or allow others to stand, downhill of the machine when it is
located on a slope.
Never start or run the engine with track motor power cables disconnected.
Chock machine front and rear when unattended or stored
