3.3.18 RUBBER TRACKS
(Machines equipped with rubber tracks only)
3.3.18.1 OPTIMAL USE OF THE RUBBER TRACKS
Rubber tracks have exceptional characteristics that cannot be found in steel tracks. However, if they are used as
steel shoes, their advantages cannot be fully exploited.
Make sure not to put rubber shoes into excessive efforts by adapting them to the environmental working conditions
and the nature of the operations to be performed.
COMPARISON BETWEEN RUBBER SHOES AND STEEL SHOES
Considering the properties of the material used, rubber tracks offer various advantages. However, their weak point
is their poor resistance. For this reason, it is necessary to know the characteristics of rubber shoes and track pads
well. Thus, the working life of rubber shoes will be extended and their characteristics will be fully exploited.
Before using rubber shoes always read section "3.3.18.3 USE OF THE RUBBER TRACKS".
3.3.18.2 WARRANTY ON RUBBER TRACKS
It is important to carry out checks and maintenance operations to guarantee a perfect track tension. Shoes must
not be used in working places where they may get damaged; for example, steel plate corners or edges, U-shaped
grooves, attachment fittings, pointed stones or crushed rocks, steel rods or iron scraps.
The warranty shall not be valid for damages deriving from an incorrect use of the machine.
3.3.18.3 USE OF THE RUBBER TRACKS
UNAUTHORIZED USES
Do not carry out the following operations.
q
Rotation or other operations over heavy rocky surfaces, rock surfaces with protrusions, steel rods or steel swarf,
or near steel plate edges damage rubber shoes.
q
Rubber shoes may get damaged or detached if stones of different dimensions, which may be found on river
banks or other working places with stones, get stuck. If the machine is used for levelling operations and the
shoes slide on the ground, the working life of rubber shoes may get reduced.
q
Do not stain the rubber shoes with oil, fuel or chemical solvents. If one of these substances gets on the tracks,
clean them immediately. Do not use the machine on roads with oil traces.
