Definitions

  • the invention relates to a hoist, the load member via a transmission from an engine is drivable, which together with the gearbox and the load handling device is a structural one Unit forms through which the load organ is passed, the two free ends the load member fixed to a suspension element to form a load and an empty strand are and the empty strand can be wound onto a storage drum.
  • hoists are also used as small electric hoists denotes and serve to move loads, the driving motor Accompanied movement of the load organ.
  • the human hand guides this device like a tool, and with the push of a button can the up and down movement can be controlled.
  • the invention is therefore based on the object of a hoist of the type mentioned to be trained so that the risk of the load falling if any Engine part is excluded.
  • This object is achieved in that on the storage drum for the Load device a centrifugal brake is provided.
  • centrifugal brakes or acceleration brakes are also for example Seat belts in cars for the empty run of the load element, i.e. the seat belt known.
  • the second strand is without Last and is stored in the supply roll or bobbin.
  • On the axis of the spring-loaded supply roll acts a brake that accelerates and on jerks reacted very sensitively. This is set such that forces, accelerations or Jerks in the load organ that are greater than the permitted and preset values block processing.
  • the secure adhesion between the attachment - So the suspension element - the storage drum and the load hook is retained, even in any of the conceivable cases in which the engine, transmission or brake fail.
  • the drive wheel for the load member is a gear is trained.
  • the load element is a flat rope or belt, the corresponding one Has recesses for engaging the teeth of the drive wheel.
  • the burden organ is on the load side and empty side of the pressure rollers (11, 12) to the drive wheel (10) pressable.
  • a particularly flat flat rope is used for the load element, so that the supply roll diameter required for the lifting height does not become too large.
  • the Flat rope used has tooth-shaped on one or both edges Recesses that interact with corresponding teeth of the drive wheel. This ensures a permanent positive connection between the load element and the drive, too if the above engine parts break.
  • the housing of the hoist is designated 7.
  • the Flanged drive motor 8 Details of the gearbox are not in the drawing shown. But you can see the drive wheel 10, which is driven by the engine.
  • This drive wheel is designed as a gear, i.e. are on its outer circumference gear-like recesses and elevations are provided. These correspond to Recesses 14 on the load member 13.
  • the load member 13 consists of a flat rope or belt.
  • the motor / gearbox / load hook unit is an assembly that hangs in the burden organ. In this way, a load strand 5 and an empty strand 4 are formed.
  • the a free end of the load member 13, namely the load strand 5, is in the example shown a crane hook 6 fixed to a suspension element 1, while the other free end, i.e. of Empty strand 4, runs onto a supply roll 2.
  • This is spring-loaded, so that the load organ is constantly under minimal tension.
  • the supply roll 2 is one Centrifugal brake 3 is provided.
  • the load member 13 runs with its load strand 5 in a form-fitting manner between the drive wheel 10 and the pressure rollers 12 and 11 and then as Empty strand 4 to the supply roll 2.
  • 9 in the drawing denotes the load hook.
