Family-owned company Conco Quarries is using Terex Trucks’ TR70 to increase productivity at its limestone mine in Willard, Missouri.

“Over the last seven decades Conco has grown from a small operation with just seven employees and four trucks to almost 200 staff members and close to 100 delivery trucks,” says Chris Upp, vice president and general manager of the quarry division at Conco Companies. “Despite the large-scale growth of the company we are still very much a family business and we pride ourselves on maintaining close relationships with our customers through excellent service.”

With 70 years’ experience, Conco has a service built on providing quality products and exceptional customer service. To help continue the smooth running of its operations at its Willard facility, the company recently purchased Terex Trucks’ 72-ton capacity rigid hauler, the TR70. Designed to aid maximum production with minimum effort, the machine is working 10-hour days hauling crushed limestone from the face of the quarry to the crusher.

Supplied by Terex Trucks’ Midwest dealer GW Van Keppel, Conco opted for the TR70 as part of an ongoing equipment renewal program and decided the dump truck was a perfect fit for its operation due to the machine’s haulage capacity which exceeded that of its existing machines by 30-tons.

“The reputation of Terex Trucks’ rigid frame trucks precedes itself and it’s great to have a respected company such as Conco putting our machines to the test,” says Dan Meara, regional sales manager at Terex Trucks. “…we knew the TR70 would fit right in, and we worked together to create a competitive offer. Once the deal was done, we did two days of training with operators on site at the quarry and the machine has been delivering since.”

The TR70 is fitted with a Detroit Diesel MTU-2000TA 12 cylinder 24-litre engine that provides a maximum torque of 3,323 Nm (2,450 lbf ft) and gross power of 567 kW. The robust rigid hauler features a high capacity body with exhaust heating to limit carry-back and increase productivity while a 15-degree sloping tail chute gives good retention and permits controlled dumping into the crusher. Effective gearing coupled with optimum weight distribution also means the machine can move more material using less fuel, less fuss, and in less time.
