Constant performance and ideal adaptation to the power requirement thanks to the hydrostatic drive!

The drive system is located at the rear of the machine and is enclosed in a soundproofed housing. The hydraulic pump is flanged directly onto the drive motor, which activates the crusher via a V-belt drive. The additional hydraulics (for main conveyor, side conveyor, vibration chute, crawler gear ...) are driven via the auxiliary drives.  

The main arguments for the hydrostatic drive:

• Individual adaptation of the crusher speed and thus optimum adjustment of the screening curve
• Possibility to change the direction of rotation - essential for the patented  DUPLEX System
• Energy adjustment as needed - the hydrostatic pressure adjusts to the power requirements of the crusher, resulting in a very constant crushing performance and the diesel engine always stays within the optimum speed range
• Thanks to the constant crushing power, the diesel consumption per tonne of production is noticeably reduced
• Crusher overload protection: no blockages due to lack of power because of constant energy reserves
• The conventional clutch is eliminated - no wear

Picture for illustration: 
- Variable power requirement of the crusher (kW)
- Hydrostatic pressure (bar) - pressure adapts to the power requirement
- Comparison with direct drive (clutch): lower energy support and crushing speed at high load -> increased oversize grain and possible crusher blockages
