Metso’s rubber lining due to the reduced
noise level and vibrations during operation.
Safety and comfort
The loud noises and strong vibrations
associated with driving a haul truck can
make the job sometimes uncomfortable,
and this can have a drastic effect on the
overall productivity of the driver. Truck
drivers belong to a group of workers that
is most exposed to whole-body vibrations
and noise. Regular exposure can cause
damage to the body, hearing loss, stress,
high blood pressure and fatigue – serious
symptoms of health and safety problems.
Employers are constantly working on
ways to improve the conditions of their
employees.
The loud noise from loading and dumping
material with a haul truck affects both
drivers and the surroundings. Improving
the function of the truck bed lining is one
way of addressing this problem.
Metso’s rubber truck bed lining improves
the working environment for drivers in a
number of ways. The rubber lining absorbs
impact better than steel and reduces
noise by an average of 10-15 decibels –
the effect of cutting noise in half or more.
Moreover, measurements show that a
rubber-lined truck bed absorbs up to 95%
of the energy from the impact during
loading. Consequently, the vibration is
dissipated before reaching other parts of
the truck structure, including the operator
cabin. This means that the operator can
feel and hear the difference when sitting
in the cabin during loading and dumping.
“Metso haul truck rubber lining absorbs
vibrations and reduces stress at every point
in the truck work cycle – during loading,
transport and loading,” says Gyberg.
Today, safety is a key priority for
aggregates producers, mines and their
related contractors. A well-functioning
working environment is key in improving
safety. A guaranteed and standardised stud
welding process for easy handling also
ensures that the lining is firmly installed to
increase safety during operation.
Crusher protection
As part of its lining solutions focus,
Metso also used Electra Mining to show
its protective lining for crushers, which is
designed for the countershaft, mainframe
and locknut. It is available for its line of
crushers including HP800, MP800, MP1000
and MP1250 models. Since last November
the main frame protective range is
extended to the complete HP range.
Mesto’s protective lining is also said
to offer four times or more wear life
than the steel lining option. The solution
is designed and specified in a seamless
process to fit selected crusher models.
The “ready-to-install” package fits directly
to the crusher and enables quick and safe
change-outs. There is no need for rework
or welding to adapt the lining which opens
up for shorter stops and further increases
crusher availability.
Metso protective lining is made of
Trellex Poly-Cer, which is a combination
of rubber and ceramic, designed to be
extremely resistant to abrasion even in
high material flows and speeds. The design
and composition is said to result in long
wear life and guarantees lower operating
costs over time.
