Portland Road and Driveway is a family-owned company in Portland, Oregon in north west USA. The owners, Tom and Amanda Bright had been looking for some time for a crusher that finally met all their requirements: recycling, quarry work, compliant with all US health and safety legislation and perfect product to a specified grain size. The company was founded in 1947 and now operates in all sectors of the construction industry. A special challenge was waiting in their own sand and gravel pit: basalt. In RUBBLE MASTER they met the right partner at last.

Looking for crushers in Las Vegas

During a course at CONEXPO, Tom first discovered RUBBLE MASTER’s mobile crushers. At the RM trade fair stand, Tom and Amanda Bright quickly realised that RM follows the same business ethos as theirs: both companies focus on customer service and are reliable and fair business partners.

Decision made at RM Xperience Days in Austria

Tom and Amanda urgently needed a machine that can crush asphalt and concrete, as well as basalt. RM listened to their requirements and took samples of the basalt back with them to Austria in order to find the best solution for the company owners. Shortly afterwards, they both decided to attend the RM Xperience Days in Austria to see the RM headquarters in person. “We were looked after from the moment we landed at Linz airport, with a schedule combining business with sightseeing. At RM headquarters it became clear that the extraordinary RM design applies not only to the crushers. The building itself is also an imposing sight,” is how Tom Bright describes his first impressions. During their visit they saw for the first time an RM crusher in action: “To say that I was impressed would be an understatement”. Three days later he left Austria as the proud owner of an RM 100GO!.

The customer relationship starts with the purchase

When the machinery arrived in Portland, RM Service Manager Scott Price and RM Sales Manager Franz Niedermeier were there to train the employees of Portland Road and Driveway. They demonstrated the most important steps and then let the operators get down to work. The crew were soon able to operate the crusher and screen on their own. With the telephone numbers of Scott Price and Franz Niedermeier they always have somebody at their side to provide support. “With the help of RM, we were finally able to meet the official regulations for crushing concrete and basalt”, says Amanda Bright about one of the greatest successes. Even after a very short period of operation the RM machines proved to be very cost effective. “Everything is technically advanced and ingeniously designed, from the impact hammers to changing the screens and the way the crusher is set up. The RM 100GO! has been developed to do one thing and to do it very well: crushing!”, adds Amanda Bright.

RM complies in full with US safety standards

The RM 100GO! fully complies with the strict requirements of the Mine Safety and Health Administration MSHA. During an unannounced safety inspection the inspector was amazed to discover the first crusher during his career that met all safety criteria without one single issue. That is thanks to the high level of the safety equipment installed as standard on RM machines.

Natural rock

Crushing at a high output and low wear, and that in every possible and impossible location, is not an issue for RM crushers. They manage to generate the highest quality value grain from natural stone on site. Depending on the desired combination of machinery. The end result is always cubic aggregate.

Abrasive rock

Quartz gravel, granite and riverbed gravel are not easy to process because high levels of quartz cause high wear. However, RM crushers are designed for such materials: thanks to their compact size they can achieve high throughputs even in tight spaces, producing valuable aggregate directly on site at all times.

Crushing gravel with 90% quartz content

Processing 24,000 tons of gravel with a quartz content of around 90 percent to produce 0-32 mm value grain
– that was the right challenge for the RM 100GO!. The mobile power pack with its wear-resistant hammers rose to this challenge in the Vienna basin extremely economically. Excavator and loader drivers are impressed.

Endurance in riverbed gravel

Building roads to connect to eastern Mexico was difficult because of the problematic terrain. It was necessary to prepare materials on site because of the remote locations of the construction sites. The RM 70GO! is ideal for challenges like this. Its manoeuvrability make it a perfect machine.

High demand for crushed sand and grit

The Swiss company Mühlebach AG has been successfully processing gravel for 40 years. As pioneers in this business field, they demand machines that are state of the art. They have now added an RM V550GO! to their fleet of machines in order to meet the demand for crushed sand and grit.

Impressive RM V550GO! performance in Argentina

At the beginning of the year the RM V550GO! made light work of transforming 0-200 mm river rock into fine 0-19 mm value grain. The awesome capacity and low diesel consumption were key in the Argentine company’s decision to purchase the RM V550GO!.
