Gantry crane parts reel design parameters described

      Technical difficulties cable reel winding speed is to ensure that the moving speed synchronized with the device, but also to ensure the cable during winding moderate pulling force. Therefore,  gantry crane  cable reel design should consider the following factors:
     1, cable specifications and types: cable cross-sectional area from 1.0 ~ 240mm2, the cable reel diameter directly affects the axial dimension and power requirements. More than 35mm2 cable section should not select a non-motorized reel (with weight can be relaxed to 50mm2), flat cable can only use a single row axial reel. Cables should be selected YCW type (power cables) and CEFR type (control signal cable), etc., softer and have a certain tensile strength. Cable outer diameter and the unit weight to be accurate.
     2, the winding length: Impact gantry crane reel radial dimensions and power demand, the longer the length of the higher power requirements. Non-electric cable reel winding difficult to complete large stroke. Ground anchor position also directly affects the power cable reel selection, common power supply anchor bit ends and the midpoint power supply in two. Non-electric power can not choose the midpoint magnetic coupling type (JQC series).
     3, the mobile device may affect the power cable reel speed motor power and the transmission ratio. When the moving speed of  bridge gantry crane  equipment more than 60 m / min, should be chosen frequency control formula (BP series).
     4, installed high-impact electric motor power cable reel, mounting height is higher, the greater the demand for power. The installation must not exceed the design requirements.
      These four parameters are gantry crane cable reel design selection is based, should be considered, but also the structure and layout of cable reel way to meet actual demand conditions.
