HYDRAULIC C-FRAME PRESS FOR RAILWAY RAIL STRAIGHTENING

We are offering a new/replica version of this press.

The press will be placed on sale by the customer in the second or third quarter of 2026 due to the project's extension.

The CF-400E/NC hydraulic press belongs to the CF/NC series and was specifically designed for railway rail straightening.
Equipped with an upper and lower table made of machined C45E steel with DIN 650 grooves.
It uses an optimized hydraulic system with a pressure of less than 255 bar, ensuring long service life and reliable performance.
It meets all essential health and safety requirements according to CE regulations.

STRUCTURE AND TABLE:
• The gooseneck structure is electro-welded and made entirely of S355JR steel.
• Stabilized and machined at the end of the welding process to ensure perfect parallelism and precision.
• Calculated and designed using finite element software.
• The upper table ensures perfect alignment with four 80 mm diameter lateral cylindrical guides equipped with maintenance-free bimetallic bushings.
CYLINDERS AND HYDRAULIC GROUP
• Single-acting main cylinder with jacketed barrel, chrome-plated piston, and maintenance-free, wear-resistant guides.
• Two lateral double-acting cylinders with chrome-plated pistons and wear-resistant guides, enabling fast start-up and return speeds.
• Includes two independent hydraulic safety blocks.
• Motorized hydraulic group with pre-fill valve for forward and reverse flow. Constant power, variable flow pump.
• Equipped with a directional control valve, a pressure relief valve, a decompression valve, and an air-oil cooling system.
• Glycerin pressure gauge with tonnage indicator.
ELECTRICAL INSTALLATION AND SAFETY
• Includes a SIEMENS safety PLC, model SIMATIC S7 1200, and a 7-inch touchscreen, model KTP-700 CONFORT, located in the control cabinet. It allows programming of semi-automatic and automatic operating modes, power, stroke, and dwell time. It has a memory capacity of 300 recipes, with each recipe capable of programming all previous values.
• Electrical and hydraulic maneuvers are redundant and self-controlled. It includes an additional safety block and self-checking devices for maneuvers and safety. It includes verification and certification of correct operation and the safety distance for photocells.
• Operation is via a low-voltage electric pedal.
• For safety, lasers and work area protection with Category IV photoelectric barriers are integrated.
