Trolley Mounted Motor For Trolley Traversal Via Cable Means Patents (Class 212/321)
  • Patent number: 8550267
    Abstract: Disclosed herein is an apparatus for cable management synchronized with telescopic motion. The apparatus is configured such that cables for transmitting power or signals to a manipulator provided on a lower end of a telescopic tube and for receiving signals therefrom are wound or unwound in response to expansion or contraction of the telescopic tube. Moreover, the apparatus is configured such that the cables are prevented from being displaced from the correct positions, a noise is prevented from being generated, and the tension of each cable is adjusted even when it is in the clamped state.

  • Patent number: 7455188
    Abstract: This invention relates to a load hoist arrangement (1) comprising a control device (50) arranged between a traverse device and a load carrying device (52). The load carrying device (52) is manually guidable in a three-dimentional space and lateral movement of said load carrying device (52) is controlled by a driving device. The driving device is controlled by recorded and transmitted force impacts from said control device (50) to said driving device. The traverse device has support elements (5, 6, 7) for supporting a traveling bridge (4), arranged to travel along said support elements (5, 6, 7), and a carriage (3) arranged to travel back and forth on said traveling bridge (4). The driving device comprises at least one motor, provided with at least two driving wheel units (15, 16), secured to said carriage (3) and two drag elements (21, 21?) secured at its end portions to opposite end portions of said support elements (5, 6) and crossing at said traveling bridge (4).
