Folding Type HC

Regular maintenance is crucial to ensure the reliability and longevity of hatch covers and cargo access systems. MacGregor's Folding Type HC model, with its medium load capacity of 1.75 t/m², is designed for efficient cargo hold access on Handysize and Handymax vessels. This system features hydraulic cylinders or motors with slow to medium speeds, integrated load-holding valves, and a robust panel construction with double steel skins or single steel skins that can be either folded or rolled. The sealing systems include options like FlexSeal, Cat-Profile, C-Seal, Omega, Omega Lite, and sponge rubber with compression bars, ensuring reliable protection against the elements. To maintain optimal performance, regular checks are essential. Inspect gaskets for signs of aging, such as discoloration, cracks, or loss of elasticity, and replace any damaged sections at least one meter in length. Compression bars should be checked for rust, bends, or rough surfaces, which can compromise sealing effectiveness and damage rubber components. Hydraulic cylinders must be inspected for leaks and corrosion on piston rods; oil levels should be monitored, and filters replaced annually. Additionally, ensure that bearing pads like Fixpad, Flexipad, Lubripad, or Unipad are not worn down by more than 4 mm, as this can lead to improper compression and increased wear. Conduct an ultrasonic tightness test per IACS guidelines to detect leaks at compression joints, and perform a hose test every six months. Keeping spare seals and valve inserts on board is recommended to minimize downtime.
