Located in the northeast US, the DA Collins Companies have been serving the aggregate industry for over 60 years. The company owns and operates several sand operations, quarries, trucking companies and concrete businesses.
Evidence of the DA Collins imprint on the infrastructure is everywhere in this wooded region. As you travel north from Albany, New York, to Glens Falls, NY up Interstate 87, almost every kilometre has been paved by a DA Collins company. Even the twin bridges over the Mohawk River were a signature project contributing to the company?s rich history. Pallette Stone is located in Saratoga Springs, NY, home of the famous Saratoga Race Course, America?s oldest sports venue where 1800 horses compete in this town of historic Victorian elegance. Forty minutes northeast is the Jointa Galusha quarry.
?Hydro, bridges, highways ? we like all of it. We welcome a challenge. There isn?t much we can?t do,? explains Tom Longe, DA Collins Companies? CEO and president. Tom has been with the organisation more than 40 years and explains that many employees are 10 to 20 year veterans. DA Collins invests in and values their people the way they invest in equipment ? for longevity. This is the same reason they were convinced they should go with Lippmann?s new 3252 mobile track jaw unit as the primary heart of their crushing operation at their Jointa Galusha quarry.
DA Collins purchased the Jointa Galusha Quarry Company in Glens Falls, NY, in 1990. The original quarry dates back to the late 1800s, so naturally, with current material processing demands, it would eventually be depleted of its reserves. Jointa Galusha explored the feasibility of opening a new quarry in the town of Hartford, NY, and after eight years of planning and compliance with strict mitigation guidelines, permitting was finally secured to access one million square metres of hard ledgerock limestone. The design and construction of a stationary secondary aggregate crushing and screening operation was underway, and the search for the right primary jaw crusher to feed the secondary plant began.
?Drawing on our experience with jaws, we wanted the flexibility of a track-mounted primary rather than committing to a stationary primary installation. Lippmann has a strong reputation for a sturdy, dependable jaw,? states Tom Longe. ?We were looking for longevity, plus mobility in the quarry was an important issue for us, so we could back away to blast, and move back up to the quarry face. The Lippmann 3252 is very mobile, and we felt the Lippmann jaw would deliver more production than the Metso or Sandvik jaw,? Tom continues.
?We had no previous experience with Lippmann, but heard nothing but good things about them throughout the industry. The new Lippmann 3252 mobile track jaw primary is located in the pit and feeds the secondary installation that has been erected up top in the quarry. Currently there is a ramp up to the secondary plant?s hopper, but we eventually look to reduce haulage costs by tunnelling and conveying the material up,? states Merile Latterell, the vice president for equipment for DA Collins Companies. Merile has been with the company since 1975, and is not only responsible for all equipment acquisition and maintenance, but manages an impressive fabrication facility with offices in Gansevoort, just north of Saratoga Springs. There, the company engineers and designs its own material processing plant layouts and fabricates all of its own conveyors and other ancillary equipment. Routine machine maintenance is also conducted at this facility.
Dennis Duellman from Milwaukee Crusher recommended the new Lippmann track plant to Tom and Merile, and the executives traveled to Wisconsin to see the machine first hand. There they met with Bob Turner, Lippmann?s president, to get a close look at Lippmann?s first track plant. Bob Turner has been closely following the track market for years and this is the first track unit he feels combines the productivity, reliability, and mobility good enough to earn the Lippmann name. Bob indicates the crawler unit?s design has been engineered, employing 22 years of experience based on many global applications.
Lippmann states its 3252 jaw, with forced feeding action, offers greater production than any other jaw in its class. The chassis is an extremely tough, proven crusher chassis system with tracks dimensioned to provide well-balanced operation. Oversized track drives provide high mobility on any terrain.
The Lippmann 3252 track unit features a triple power gear transmission system specially designed for crawler crusher use. This direct crusher drive is designed to provide the best possible power efficiency with twin VDP pumps employed for hydraulic drives. The result is reduced fuel consumption and greater system efficiency. The main discharge conveyor?s wide belt ensures greater discharge capacity. The tail end is hydraulically raised for moving and lowered for operation. An intelligent control system offers easy to use information displayed on one screen, with single button process start, automatic process control, and built-in fault diagnostics. The machine is operated by remote control from up to 250m2 away, with an override umbilical option for emergency or service use.
?Since the 3252 is Lippmann?s first track machine, this was a test to see if we could get the production we wanted to feed the rest of the plant,? say Tom and Merile.
?The plant has been very productive. We?re currently producing 450 tph of 6.5 inch material,? states Merile.
?We may even eventually go up to the next size Lippmann jaw with a 20? feeder. That would push us up to the next level for even greater capacity,? adds Tom. DA Collins bought a massive, new Cat 988 front-end loader just to feed the high capacity, heavy-duty track jaw.
?The Lippmann track unit is a well built machine,? say Tom and Merile. ?Lippmann?s customer support and response have been excellent. We had some minor issues where a wear plate came off and cut the conveyor belt, but Lippmann was great. They were out here and had us up and running in record time, and it was all done on a handshake.?
Safety is a top priority at DA Collins. The US Occupational Safety and Health Administration has given DA Collins Voluntary Protection Program status, the only construction company to achieve this merit level. Consistent with these objectives, the Lippmann 3252 track jaw system design has been test audited for safety and has been thoroughly proven in the field. Belt drives and conveyor nip points are well protected. Service platforms are designed with operator safety in mind. The IC700 control system incorporates features that protect both the operator and machine, and emergency stops are well marked and positioned.
The 3252?s diesel engine complies with EC Stage IIIA/EPA Tier 3 emission regulations and is designed to offer lower fuel consumption over rivals in its class per tonne produced, due to the TPT power match system. The machine is also designed for low noise pollution. A leak-free hydraulic system includes a collection system for hydraulic maintenance. For transport, a minimum amount of dismantling is required, with hopper walls folding hydraulically.
The stationary secondary installation consists of a Telsmith 66S cone crusher, a 6? x 20? Diester scalper, a Cedarapids MVP 450 cone, a recrush bin, two Diester 8? x 20? finishing screens, radial stackers and assorted conveyors. The plant produces a variety of high quality aggregate products used in local projects, as well as some large construction and dredging projects in Long Island. By relying on innovation, state of the art technology, reliable equipment and dedicated, knowledgeable employees, DA Collins provides cost-effective products that ensure the success of any heavy-duty construction project.
Together, Pallette Stone, Jointa Lime, and Jointa Galusha manufacture aggregate materials for ready-mix concrete, pre-cast concrete, asphalt, crushed limestone, agricultural lime, crushed concrete sand, and washed mason sand. Applications include residential, commercial and industrial construction, septic leach fields, road bases, road surfaces, railroad ballast, drainage systems, filtration beds in water treatment systems, and structural embankment fill.
In Australia, Lippmann machines are available from Global Crushers & Spares (east coast and southern states) and 888 Crushing & Screening Equipment (west coast and Northern Territory).
