Crane main technical parameters (1)

  Crane Crane parameter is the main technical performance indicators parameters. Is the basis for the design of  hoist gantry crane  , crane safety requirements is an important basis. Crane main parameters are described below:

Gn is the nominal weight crane can safely lift spreader or materials with separable attachment quality combined. For its rated capacity crane hook is its safe lifting of the quality of materials. But with separable spreader (such as grab, electromagnetic chuck, balance beams, etc.) of the  steel crane   lifting and material quality which is the sum of rated capacity, which allows lifting the quality of materials is a valid starting weight. Calibration plate on the crane lifting weight, usually refers to the rated lifting capacity crane. From the weight of signs should be prominently displayed in a prominent position on the crane structure (which is one of the elements  overhead gantry crane  safety checks) to prompt the operator to avoid overloading. It should be noted that, for the type of crane jib, its rated capacity with the magnitude of the increase is smaller. Such lifting cranes lifting torque characteristic index is used to represent the value of the calibration plate on specifically refers to the boom at the minimum amplitude of the maximum weight. Clear that this is a safe operation of the crane is very important.
