Side-Rolling Hatch Cover · Hatch Covers & Cargo Access
Crew and engineers on board rely heavily on efficient cargo hold access systems to ensure smooth loading and unloading operations, maintaining the vessel's operational integrity and safety. MacGregor’s Side-Rolling HC is designed for medium-capacity applications, offering a load capacity of 1.75 t/m². This system features hydraulic cylinders or motors with slow to moderate speeds, integrated load-holding valves, and panels that can be configured in two to six sections per hatch. The panels are available with double steel skins (foldable covers) or single steel skins (rollable covers). Sealing options include FlexSeal, Cat-Profile, C-Seal, Omega, Omega Lite, or sponge rubber with compression bars. The system’s support pads—such as Fixpad, Flexipad, Lubripad, or Unipad—are designed to transfer weight during ship movement. The hydraulic filling is tailored for marine use, incorporating a heating and cooling system, and the tank size is minimized to save deck space. Corrosion protection measures include stainless steel piston rods or sleeves, bronze ball bearings, and lubrication nipples between seals. Common maintenance issues involve inspecting gaskets for aging, compression bars for corrosion, hydraulic cylinders for leaks, drainage systems for blockages, bearing pads for wear, and compression joints for leaks. Spare parts are available directly from MacGregor with a lead time of 3-8 weeks, and it is recommended to keep seals and valve inserts on board. Rail alignment should be checked at every dry-dock, and cross-joint packing should be replaced as needed.
