Anti-vibration pads:
The machine is mounted on 4 specially manufactured pads, each measuring 450 x 450 x 85 mm.

Oil tank with oil cooling:
The tank has a capacity of 1500 L. The oil is cooled by a dedicated pump that starts operating at 40°C.

Oil filtration system:
Independent of the main and cooling pumps, the press is equipped with a separate filtration circuit. The pump runs continuously but only requires 1.5 kW.

Energy-saving function:
If the main pump is not required for a set period, it switches to energy-saving mode and consumes only about 2 kW/h. It is immediately fully operational again when pressure is needed.

Safety technology:
Safety components are provided by Pilz. The light curtains are also from this manufacturer.

Control cabinet:
40% of the space in the control cabinet is reserved for subsequent installations. All components in the cabinet are from Schneider.

Screws:
All screws used in the machine are zinc-plated or yellow galvanized.

Oil tray:
The hydraulic block and pump are located in a small oil tray to collect any oil during repair or hose replacement.

Noise emission:
The press produces a maximum of 75 decibels according to standards.

Accessories:
Roller loading bridges:
2 removable loading bridges, each 1500 mm long, with rollers and large heavy-duty castors.

Parallelism monitoring:
Both cylinders are monitored using Balluff linear measurement systems and Sick cable extension encoders. Parallelism monitoring is activated at the start of the press cycle. The monitoring accuracy can be configured via the control system. During idle travel, this function is deactivated. Two SICK cable encoders measure the left and right positions of the ram. The control system adjusts the oil flow to the cylinders via special high-speed valves. The required parallelism accuracy is less than 1 mm across the full width.
