Hydraulics: All press hydraulics are assembled exclusively with BOSCH-REXROTH / Parker / HAWE components. The control cabinet contains only components (SIEMENS) that are readily available in Germany. All safety devices apart from the light curtains are SICK brand. The controller supplied is SIEMENS (S7 1500), including the 15-inch touchscreen panel. The SIEMENS remote maintenance unit SECOME - Ethernet is included in the scope of delivery.

SPECIAL FEATURE: Our double-ram design in combination with a piston accumulator allows full performance to be delivered using a single 90 kW main motor.
