Ship Cranes require high reliability, smooth operation, corrosion resistance and low temperature resistance.

According to customer’s special requirements and working environment, Hengli can provide different coatings, from economical nickel-chromium coating to some superior coatings: APS coating, HVOF coatings and laser cladding. We can also use stainless rod to prevent corrosion. The material we used for marine cylinder has a high impact energy under low temperature. Double piston accumulator intelligently designed by Hengli can improve the efficiency of hydraulic system remarkably.
