HLM CRANES: Fully foldable telescopic cranes with HLM 25/3S The HLM cranes with their rack and pinion slewing system are very compact and light. This makes the HLM type ideal for use on small vessels, especially where space is limited. Cranes of this type, our ‘workhorses of the sea’, are indispensable for auxiliary vessels including multifunctional work boats, tugs and pontoons. CHARACTERISTICS • The crane is able to work in any configuration; with boom extended upwards or folded downwards offering great manoeuvrability • Rotation exceeds 360°. This is possible because the crane is fitted with a double rack and pinion system with bronze bushes that guarantees safe operation, even at excessive heel and trim angles. CONTROL AND SAFETY • Stationary fixed control console • Counterbalance valves directly mounted on each cylinder provide a fast response • Proportional Electrohydraulic Control Valve Block with internal compensation for simultaneous movements and self-centring manual levers; supplied by primary worldwide producers • Electrohydraulic load moment limiting device; prevents the crane being overloaded and damaged. STRONG AND RELIABLE Doubling the number of racks and cylinders doubles the power of the slewing system. Moreover, the life of these components is extended because the load is shared. CUSTOMISATION The HLM crane series is standardised, however, there are a surprising number of options allowing a degree of customisation. 6
