Job Report R 974 The R 974 loading shotrock in West Roxbury, Massachusetts. Situation S.M. Lorusso & Sons, Inc is a family owned company headquartered in Walpole, Massachusetts producing crushed stone, sand and gravel. Lorusso operates six quarry locations throughout southeast Massachusetts and Cape Cod; one site has been in operation since the mid 1800s and still has great potential for future digging. S.M. Lorusso & Sons is currently in its fourth generation and run by Tony Lorusso and his son, A.J. Lorusso; the operations on Cape Cod are run by Tony’s brother Sam Lorusso and his children, Laura Peterson, Sam Jr. and Paul Lorusso. S.M. Lorusso & Sons has maintained its success through seamless operations and maximizing resources. All aspects of the company are carefully monitored to ensure optimum production levels are being achieved. Task ! Performance Reliable equipment and quick cycle times are major factors that must be considered when trying to optimize production. Lorusso’s machines work 9 hours a day, 5 days a week producing crushed stone, sand and gravel with a portable rock crushing plant as well as stationary crushers. Since purchasing the R 974 in January, Lorusso has experienced an increase of 10-15% in production. Comparing a 6 yd bucket on the excavator to a 8 yd bucket on the loaders, Lorusso was surprised and very pleased with the outstanding performance of the R 974. For years, Lorusso used wheel loaders to either load directly into the rock crusher or load trucks which feed the rock crusher. When Lorusso planned to switch loading with the wheel loaders to excavators, durable, reliable and efficient equipment was a necessity. Lorusso said, “The excavators give you the ability to place the load. Placing the load makes a huge difference, there is less spillage and less cleanup. You have a clear view of the size rocks that are being placed in the crusher, reducing the risk of oversized rocks going into the crusher and slowing production.” ! Solution Lorusso purchased two R 974s, Liebherr’s large crawler excavators, to take over loading the trucks and loading directly into the portable crusher. Lorusso chose a machine sized slightly larger than needed so it would not be running at 100% capacity all the time, decreasing the amount of wear and increasing longevity. Lorusso also chose the Liebherr because it has a lower operating cost per hour than other manufacturers. Switching to the crawler excavator as the main loading tool also decreases Lorusso’s reliance upon rubber tires. Liebherr’s crawler excavators have excellent digging forces, bucket fill factor and very fast cycle times. Lorusso said, “We’ve never had a backhoe that size before and there were a lot of skeptical people that didn’t think it would work. Now they can’t believe how fast and how strong it digs.” Liebherr Construction Equipment Company 4100 Chestnut Avenue, Newport News, Virginia 23607 PH: 757-245-5251, Fax: 757-928-8701 www.liebherr.com, E-Mail: [email protected] The excavator is 20 –30 seconds faster than a wheel loader when loading 60 ton trucks. The operators prefer to use the excavator for loading and they have also commented on the comfort of the cab and how smoothly it drives; Lorusso is pleased because the operators’ productivity levels remain high through the end of the day. Lorusso has been very pleased with the after sales support he has received from his local dealer, Tools 4 Hire. “So far it’s been excellent. I have not had any issues, but they take care of everything. They are stocking a lot of parts and what they don’t stock they receive very quickly.” Technical Data R 974 B Litronic Engine ____________________ Liebherr D9408 TI-E Engine Output __________________ 395 kW/537 HP Operating Weight _____________179,680-194,440 lb Gooseneck Boom ________________________ 23’8” Stick ___________________________________ 9’6” Bucket Capacity _________________________ 6 yd3 Printed in the USA by Letton Gooch #####-6-30-2006 Subject to change without notice. ?
