MARATHON Hydraulic C-Press (or C-frame press) is a type of hydraulic press characterized by its C-shaped frame, allowing easy access to the workpiece from three sides. These presses are used for tasks such as punching, stamping, bending, and assembling. Below are common specifications for hydraulic C-presses:

1. Pressing Force

• Range: 10 tons to 300 tons, depending on the model and application.
• Suitable force depends on the material and thickness being pressed.

2. Throat Depth (C-Frame Depth)

• The distance from the centerline of the ram to the C-frame, determining the size of the part that can be processed.
• Range: 200 mm to 1000 mm or more, depending on press size.

3. Stroke Length

• The distance the ram can travel during each pressing cycle.
• Range: 100 mm to 600 mm or more.
• Adjustable stroke lengths are common for precision applications.

4. Daylight Opening (Open Height)

• The maximum space between the ram and the bed when fully opened.
• Range: 200 mm to 1,500 mm.
• Larger daylight openings allow for bigger workpieces or taller tooling setups.

5. Working Table Size

• The dimensions of the working bed where the workpiece is placed.
• Range: 300 mm × 300 mm to 2,000 mm × 1,500 mm or larger.

6. Ram Speed

• Speed at which the ram moves during the press cycle (typically includes approach speed, pressing speed, and return speed).
• Approach Speed: 50 to 300 mm/sec.
• Pressing Speed: 10 to 50 mm/sec.
• Return Speed: 50 to 300 mm/sec.

7. Motor Power

• Power required for the hydraulic system.
• Range: 3 kW to 30 kW or more.
• Higher power is needed for presses with greater force or faster cycle times.

8. Hydraulic System Pressure

• Maximum pressure in the hydraulic system, often measured in bar or MPa.
• Range: 10 MPa (100 bar) to 30 MPa (300 bar).

9. Control System

• Manual, semi-automatic, or fully automatic operation.
• May include a PLC (Programmable Logic Controller) for automation and precision control.
• Controls include force adjustment, stroke length, and cycle time adjustment.

10. Frame Construction

• Typically made from heavy-duty welded steel to minimize deflection and improve stability.
• Robust frames for precise and repeatable operations.

11. Safety Features

• Emergency stop buttons, light curtains, and two-hand control for operator safety.
• Overload protection and pressure relief valves to prevent damage to the press and tooling.

12. Application-Specific Tooling

• Customizable tooling options for specific operations like punching, bending, forming, or stamping.

13. Power Supply

• Voltage: Commonly 220V, 380V, or 440V, three-phase.
• Hydraulic pumps powered by electric motors or external hydraulic power units (HPUs).

14. Weight and Dimensions

• Machine weight: From 1,000 kg for smaller presses to 10,000 kg or more for larger, high-tonnage models.
• Dimensions depend on capacity but typically range from 1,500 mm × 800 mm to 3,000 mm × 2,000 mm or larger.

15. Pressing Cycle Time

• Range: 10 to 30 seconds, depending on stroke length, material, and press configuration.

Hydraulic C-presses are widely used in industries like automotive, aerospace, and metal fabrication.
