Personnel haulage can be carried in
inclined headings with the gradient of
up to 30°. In addition to the cabins for
personnel haulage, man benches are
also used. FAMUR’s range includes the
PIOMA S-8 and FTB 8 benches.
Safety the primary factor
The most important factor in the
transportation of people is safety,
especially if the transport occurs in
inclined headings with gradient of over
20˚. The main element of personnel
haulage sets are passenger cabins or
benches, but the safety is determined by
the cab pulling machine and the
protection equipment that prevents
uncontrolled running down the
heading.
In FAMUR’s range, the main
equipment for the suspended monorails
drive is the FMS (Famur Monorail
Standard) diesel-powered locomotive
(Figure 4). In addition to the solutions
ensuring reliable operation and low
operating costs, the locomotive is
provided with innovative solutions that
improve operational safety.
One of the risks when driving on
inclined roads is uncontrolled
movement of the monorail unit, caused
by slippage of the locomotive driving
wheels. This is the result of a
combination of high humidity in the
headings and the dust deposited on the
rails due to the forced air circulation.
The FMS is the first monorail locomotive
worldwide equipped with anti-slippage
system for driving wheels. An applied
synchronisation system of the driving
wheel speed not only limits slippage of
the wheels but also maintains the supply
pressure in hydraulic drive motors. This
means that the locomotive does not lose
pulling force in cases where one of the
wheels has slipped, keeping the entire
transport set on the monorail route.
The consequence of uncontrolled
movement of the whole monorail unit is
an emergency braking event occurring
automatically when the running speed
is over approx. 3 m/sec. The emergency
braking retardation can exceed
9.81 m/sec.

and braking forces centred
on a few (two to five) rails may result in
breaking of rails, which are suspended
to the roof by means of chains. The FMS
locomotives are provided with braking
systems that can be positioned at any
place along the whole transport set,

forces centered (concentrated) on one side of the set.
