The special application environment at sea brings great challenges to marine cranes. On the one hand, it needs to have higher reliability and smooth operation to ensure positioning accuracy and transportation efficiency. On the other hand, there are high requirements for its corrosion resistance and low temperature resistance. Hengli can provide standard nickel-chromium coatings, plasma spray coatings, supersonic flame spray coatings, other corrosion-resistant technologies and integral stainless steel piston rods according to customer needs and the actual use environment of marine cranes.
For equipment with low temperature resistance requirements, materials with excellent low temperature impact properties will also be used to ensure that the crane is sufficient to withstand harsh environments. In addition, Hengli provides double-piston accumulators for cranes with heave compensation. Its innovative structural design makes the weight lighter and improves the efficiency of the entire hydraulic system.
