  • The working principle of the gantry crane hoisting mechanism The motor of the crane is connected together by a coupling and a reducer. It works by rotating the low speed shaft of the reducer to bring the reel and hook together with the wire rope and so on.

  • How To Operate Gantry Crane – Professional Gantry Crane for Sale

    The gantry crane operation mechanism generally only four active and from the train wheel. If the lifting weight is very large, it often uses the method of increasing the wheel to reduce the wheel pressure. When the wheel exceeds four, the hinged balanced frame device must be used to make the load of the gantry crane evenly distributed on each wheel. Gantry Crane Price for Sale

  • A gantry crane is a crane built atop a gantry, which is a structure used to straddle an object or workspace. They can range from enormous "full" gantry cranes, capable of lifting some of the heaviest loads in the world, to small shop cranes, used for tasks such as lifting automobile engines out of vehicles. They are also called portal cranes, the "portal" being the empty space straddled by the gantry. The terms gantry crane and overhead crane are often used interchangeably, as both types of cran
