Mining, coal and aggregate equipment that extract deposits, separate waste and transports materials, such as minerals, ores, precious metals and wood chips, undergo extreme vibratory motions in surface and underground mining operations. Both domestic and international equipment manufacturers have relied on Duer/Carolina Coil as their trusted source for reliable springs to keep their machinery operating at optimal performance levels.
Duer/Carolina Coil offers in-house powder coating and liquid paint capabilities to add protection against corrosion, but we also have approved subcontractors for E-coating, plating and other anti-corrosive coatings.
Quality begins with the integrity of our steel supplier. From these materials to our commitment to improve our people, processes and machinery, Duer/Carolina Coil is a story of lasting partnership and continuous innovation, delivering the most reliable vibratory springs and more to your company.
To lower life-cycle costs and prevent component damage, consider redesigning the springs you are using in your screening applications. Linear-motion screens and circular-motion screens used for frac sand, scalping, wash/rinse, separating and sizing aggregates require heavy duty springs for vibration and shock absorption.
Duer/Carolina Coil works with OEMs to provide springs to reduce shock and vibration and add stability to both stationary and mobile cone crushers, gyratory crushers, impact crushers, jaw crushers and vertical impact crushers. These heavy-duty springs enhance the wear material quality of crushing equipment used in the quarrying and gravel pit, cement and recycled materials industries.
Surface Mining Vehicles
Durable undercarriage parts and components lower operating cost and increase undercarriage life. Duer/Carolina Coil provides idler recoil springs, inner recoil springs and outer recoil springs for track adjusters, track frames and spring assemblies. For all wheel drive trucks, Duer/Carolina Coil can provide independent suspension springs for enhanced maneuverability in harsh terrain.
