Heila Cranes manufacture heavy-duty cranes expressly designed for marine applications both shipboard and off-shore. Stiff Boom Cranes Designed for general cargo handling and service onboard ships and offshore units. Stiff boom cranes are most suitable when the amount of space on deck is ample. These cranes offer a cost-effective alternative to knuckle booms or telescopic booms. Those cranes are fixed where the lift is mostly done by the winch. Cannot be hydraulically extended and retracted and have no knuckle function. Telescopic Boom Cranes Telescopic boom cranes can be hydraulic extended and retracted without a knuckle function. These cranes should always be executed with a hoisting winch installation. HM type for the small capacity cranes with slewing cylinders. HMR type for the bigger capacity cranes with slewing rings. Fully Foldable Telescopic Cranes These cranes are designed to keep the constant the torque moment, reducing the 'pendulum effect' of the load. They require a minimum of deck space. HLM type designed for the small capacity cranes with slewing cylinders. HLRM type designed for the bigger capacity cranes with slewing rings. Knuckle Boom Cranes These knuckle boom cranes can be found on vessels with a big deck area and are also used on fixed platforms. The costs compared with knuckle booms with hydraulic extension are less high. Another advantage is that these cranes require less maintenance due to the fact that there are fewer joints. HM type designed for the small capacity cranes with slewing cylinders . HR type designed for the bigger capacity cranes with slewing rings. Offshore Cranes
