Door Locking Hydraulic Cylinder

Door locking hydraulic cylinders are critical for securing heavy-duty access points in industrial and hazardous environments. These robust actuators provide fail-safe clamping force (typically 5-200 tons) to maintain structural integrity under extreme conditions.     In **steel mills**, they securely lock furnace doors and rolling mill enclosures, withstanding radiant heat up to 250°C while preventing accidental openings during operation. Their thermal-resistant seals and water-cooled jackets ensure reliable performance near molten metal.     **Marine and offshore** applications utilize corrosion-resistant models (316L stainless steel) to seal watertight compartments and hatches. The cylinders maintain constant pressure despite vessel motion, with IP69K-rated models resisting saltwater immersion.     For **nuclear facilities**, specially certified versions feature dual-redundant locking mechanisms and seismic-rated construction. They control containment door access with ±0.5mm positi…
