The Portuguese company Sicobrita S.A. has been operating a quarry in the Serra do Sicó near the city of Pombal for more than 30 years, putting its trust in Epiroc's hydraulic hammers since 2005.

Thanks to its location in one of the most important limestone massifs in Portugal, the Serra do Sicó limestone quarry has a large extension in a licence area of approximately 35ha. The company Sicobrita uses precise mining and crushing methods that produce limestone with high purity and a high of whiteness, with effects on the environment always kept as low as possible. Thus the previous hammer used, the MB 1700, the company valued, among other things, the automatic lubrication system, energy recovery, low noise and vibration levels and effective dust protection.  

Its new MB 1650 continues to offer all of these features, in addition to being lighter and more compact than its predecessor. The hydraulic hammer can continue to be used in problematic production processes, but at the same time contributes to an easier handling and a reduction in operating costs, being suitable for carriers from 19t to 32t. The performance of the hydraulic breaker is optimised by ‘AutoControl’, an automatic stroke switch mechanism. The ‘EnergyRecovery’ feature uses the recoil force of the piston to increase performance, which like the ‘VibroSilenced Plus’ system reduces vibration. The integrated ‘StartSelect’ valve allows the operator to adapt the launch behaviour of the breaker to operating conditions in a few simple steps.

The automatic lubrication system and patented dust protection system, and the redesigned service opening, improve the longevity of the components. Lubricant consumption is reduced, dust penetration is prevented and maintenance is facilitated. In addition, the MB 1650 is without a high pressure accumulator, which in turn significantly reduces repair costs. The MB 1650 is a tool designed for a wide range of applications in mining and quarrying, demolition and renovation works on construction sites and in the metallurgical industry.
