Key benefits
MacRack improves hatch cover operations by simplifying system architecture and reducing dependence on oil-based components.
- Reduced installation and commissioning effort through a simplified, integrated system design.
- Spill risk is eliminated, and routine maintenance demands are reduced by removing hydraulic oil and hydraulic hoses.
- Consistent performance in cold and harsh climates is delivered by reliable electric operation.
Together, these benefits help you lower the total cost of ownership while maintaining safe and dependable cargo operations.
Key features
MacRack’s patented solution combines lifting and rolling into one electrically driven unit mounted on the hatch coaming.
- The combined rack-and-pinion drive integrates lifting and rolling into a single compact unit.
- The lever mechanism converts motor rotation into a controlled vertical lift and smooth rolling motion.
- Variable frequency drives optimise torque and speed throughout the operating sequence.
- The portable operating unit allows safe control with full visibility along the coaming.
- Disengaged-at-sea design allows free movement of the hull and cover without structural stress.
These features work together to deliver smooth operation, simplified maintenance throughout the system lifecycle, reliable sealing, and protection for your cargo.
