Recently, Wuhan Marine Machinery Co., Ltd. completed the drawings and process design of the first 500-ton shark pliers (hydraulic chain lock stopper or hydraulic cable clamp) and retaining piles in China. At present, the product has entered the production stage.
Shark pliers are an important part of the marine ship deck machinery. The main function is to clamp the towline wire rope and avoid the steel wire rope swinging left and right during the navigation of the ship to avoid damage to the ship's side and wire rope. Its design and manufacture have long been a foreign monopoly. Based on the successful development of small-tonnage shark tongs in the early stage, Wuhan Shipbuilding has repeatedly carried out simulation analysis through repeated verification of design, and overcome the difficulties in the structure, performance, safety and simulation test of large-tonnage shark tongs, and completed the first 500 in China. Tons of shark pliers and retaining piles.
