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.
