It is understood that most of the gearboxes used in China before this time were imported from Germany's ZF and the US Double Disk Company. The HCQ700 lightweight high-speed gearbox was developed by the Marine Research Institute of the Hang Tooth Technology Center. The advent of the HCQ700 has broken the reliance on imported products. This type of gearbox is small in size, light in weight and high in transmission power. It has good maneuverability and emergency commutation performance. It is equipped with a hydraulic control system, a cooling system and an alarm display system. The technical indicators can fully meet the needs of the new high-speed ship The requirements can be widely used in administrative law enforcement ships, port supervision ships, high-speed passenger boats, marine engineering ships and yachts.
Hangfang said that compared with imported products, its HCQ700 light gearbox not only enables users to save more than two-thirds of the cost of the gearbox purchase, but also enables users to get more excellent, convenient and efficient after-sales service. Due to the good market prospects, Hangfang has begun mass production of the HCQ700 series of lightweight high-speed gearboxes.
A Chinese maritime surveillance ship that installed the HCQ700 lightweight high-speed gearbox developed by Hangzhou Advance Gearbox Group Co., Ltd. was successfully piloted in the Pearl River waters. This means that the new product, which has been replaced by imported products, has been recognized by the market.
