HYDRAULIC TUBE STRAIGHTENING PRESS WITH TRAVELLING GANTRY – PRT Made In Italy

Maximum pressure valve

As a safety measure to guarantee the operator's safety and to safeguard the machine, a maximum pressure valve is installed inside the hydraulic control unit on all hydraulic presses produced by SICMI.

Anchoring electrical cables

The tubes for the passage of the electrical cables are anchored to the press frame by means of special collars.

Unlike many competitors who use simple plastic ties that are destined to dry out and break quickly, these collars are made of highly resistant material and are screwed to the structure of the press.

Anchoring hydraulic pipes

As a safety measure, the hydraulic hoses of all the presses produced by SICMI are firmly fixed to the machine frame using special collars which prevent any movement of the hydraulic hose.

These collars have the base welded to the frame, while the upper part is screwed.

Stopflex anchor

All SICMI hydraulic presses are equipped with the Stopflex hose retention system, designed to secure pressurized hydraulic hoses and prevent uncontrolled movement in the event of fitting failure.

The system helps reduce the risk of the whip effect, protects personnel and equipment, and limits hydraulic oil release into the working area.

Current transformer

24V Low-Voltage Control System

The press operates with a 400V three-phase power supply. For operator safety, a transformer inside the electrical panel reduces the control voltage to 24V, minimizing the risk of electric shock.

• 400V Three-Phase Power Supply
• 24V Low-Voltage Control
• Built-In Safety Transformer
• Reduced Electrical Shock Risk

Pipe lifting and rotation supports

Hydraulic Pipe Supports

The hydraulic supports lift and rotate the pipe, making it easier to position and handle during straightening operations.

The supports slide along the press bed and can be manually positioned according to the workpiece length.

Anti-fall and anti-explosion valves

All SICMI hydraulic presses are equipped with anti-fall and anti-burst safety valves to protect the operator and machine.

• Anti-Fall Valve – Keeps the hydraulic cylinder securely in position if a hydraulic hose fails, preventing the upper platform from falling.
• Anti-Burst Valve – Releases excess hydraulic pressure if it exceeds the permitted limit, helping to protect the cylinder from damage.

Digital control with Siemens touchscreen display

The optional Siemens KTP 700 Basic touchscreen provides precise control of the hydraulic press, including:

• Cylinder up/downstroke limits
• Working pressure and pressure-holding time
• Decompression time
• Piece counter
• Pre-stop function with 0.1mm accuracy
• Alarm management
• Manual or automatic operation

Up to 100 machining programs can be stored. Stroke and pressure are monitored via a wire encoder and pressure transducer.

When equipped with a hydraulic cushion, its operation can also be controlled through the touchscreen.
