Product Description

20t Four Ropes Marine Crane Clamshell Grab

It is an effective tool for loading and unloading bulk ores such as ore, scrap, nickel ore, domestic waste and wood chips under all kinds of harsh environments. For some more cobblestones, they can also be used for river dredging. The grab is simple in structure and easy to operate, and it can accurately finish opening and closing actions in various states. The grab is designed by three-dimensional virtual design, and ANSYS is used for strength analysis and checking of the main components of the grab. The weight distribution is more reasonable and the service life is longer. The grab is suitable for loading and unloading of the double winding crane. The grab is equipped with lifting chain and can directly connect with the lifting rope of the crane. The connection form of the wire rope can be customized according to the requirements of the crane. When the multi flap grab is used to grab large scrap or domestic waste, to facilitate insertion of tooth tips, the general bucket is designed to be semi open.
