Talking about the current mainstream of development overhead crane

 Overhead crane development in our country for nearly five decades of history, fifty years, the basic mechanical structure  overhead bridge crane  working device, rotary equipment, travel agencies, etc. for its form and appearance of the shape basically did not change significantly, this is because the basic principle of overhead cranes and performance is not essentially changed.
     To meet the massive infrastructure needs and the needs of national defense construction, bridge crane is the general trend of the development of small-scale to large-scale development of small to large hoist gantry crane  lifting heavy development, crane current mainstream of development to large and efficient development.
     Bridge  sino hoist  equipment reliability studies to be further improve and perfect, crane work, each hanging weight, lifting height range are different, showing a random phenomenon in the past taken to determine the amount or maximum hoist design, there are deficiencies, the lack of rationality is to maximize the good design should meet the actual situation, which is designed to bridge crane equipment workers endeavors.
