The products and solutions Hägglunds will showcase at MINEXCHANGE leverage the unique characteristics of hydraulic direct drive technology — delivering power directly to the drive shaft with full torque from zero speed and protection from shock loads — to maximize the efficiency and uptime of conveyors, feeders, crushers, drums, bucket wheel reclaimers, kilns and more.
System demonstrations and booth presentations will highlight the unique features Hägglunds technology offers, including:
Torque Control: Direct drives with low speed and high torque can provide full torque from standstill, without time restrictions. Hägglunds hydraulic direct drives can operate continuously throughout their power range up to their rated torque, from zero to full speed.
Start-Stop-Reverse: A Hägglunds hydraulic direct drive reacts especially quickly due to its very low moment of inertia. They are able to switch automatically from driving to braking mode, and the direction of rotation can be switched quickly by changing the direction of the oil flow.
Shock Load Resistance: Shock loads can damage critical equipment and lead to major unplanned downtimes. With direct drive motors applying power directly to the core of conveyors, crushers and feeders, the direct drive offers a solution without mechanical play and with a low moment of intertia so it can easily withstand vibrations, external shock loads and changing load directions.
Key solutions and technology that will be presented in the booth include:
Fusion Direct Hydraulic Drive: Released in 2022, Hägglunds Fusion won industry recognition two times. The Fusion is a unique drive system that puts everything on the torque arm, from the hydraulic motor and pumps to the cabinet that houses them, making high torque and total reliability available from a single unit – in a footprint that was previously unthinkable.
Atom Hydraulic Motor: Combining the right size with Hägglunds performance, it offers the right fit for mining applications where both compact size and high power density are required. With a maximum torque of up to 13.6 kNm and a specific torque of 40 Nm/bar, the Hägglunds Atom hydraulic motor can supply maximum power of 394 kW, outstripping other motors in its class.
CB Direct Drive Motors: Tough and rugged with a wide range of sizes and displacements, the Hägglunds CB provides the right solution for many heavy-duty applications, such as shredders, feeders and roll mills. It combines space-saving designs with a wide range of sizes and displacements.
Rineer Motors: Bosch Rexroth’s Rineer motors offer the highest power density with maximum torque, as well as robustness, even under the most adverse climatic conditions and high dirt loads. Our Rineer motors are frequently used in the mining and construction sectors, on drilling and winch applications.
In addition to those exhibits, booth visitors can meet one-on-one with Hägglunds technology experts to discuss their unique challenges and requirements. Experts can provide practical recommendations on ways that the Hägglunds technology can help maximize uptime and productivity in mining operations.
MINEXCHANGE 2023 takes place Feb. 26–March 1, in Denver, Colo.
