Twin Disc says it’s ideal for driving pumps, grinders, crushers, dredgers, chippers, shredders and heavy-duty drills, plus other severe applications.

The HP500 has a modular design allowing for side-load applications. An advanced control system allows for smooth engagement of the driven equipment.

A key feature of the HP500 is the auxiliary drive pump towers with 299kW maximum capacity per tower, or 336kW maximum for both. They’re rotatable by 0°, 45° and 90°, either clockwise or counter-clockwise, to allow for clearance in any installation. Speed increase ratios of 1:1, 0.77:1 and 0.83:1 are available, as are dual auxiliary or single pump tower versions. Additionally, a spring-applied, hydraulically released brake (SAHR) has been added as a standard feature.

Pads and splines are easily interchangeable to accommodate varying pump sizes. Sizes SAE A through SAE E are available. The HP500 is available with SAE #1, SAE #2, or SAE #3 input housings and SAE 355 (14″), SAE 290 (11.5″), and SAE 255 (10″) input couplings.

In 2017, Twin Disc debuted the HP800, remote over centre RO 314/311, and remote-controlled RC214 and RC314 PTOs. This year, Twin Disc celebrates its centenary in manufacturing.
