The rubber lining absorbs impact better than steel and reduces noise by 10-15 decibels.

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

Metso's protective lining offers four times or more wear life than steel options.

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. b

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
