Definitions

  • the present invention relates to a trolley for cableways having a wire running via an end sheave via the trolley and back to the winch.
  • the purpose of the present invention is to make it possible to secure the trolley at an arbitrary place while lifting and lowering a load, without its being necessary to undertake locking of the trolley to a supporting wire. At the same time the wire stags taut through the entire process.
  • the driving of the trolley along the cableway takes place when a radio controlled valve between the oil motors closes the oil flow to both the lines on the oil motor, connected to the cam/hoisting line drum, and simultaneously disengages the second motor so that it is able to run freely.
  • Figure 1 is a schematic illustration of the trolley.
  • Figure 2 is a schematic illustration of the connection between the oil motors.
  • Figure 1 is a schematic view of the trolley for cableways with a pulling wire 7 passing one time around a cam 1 with the return wire 6 passing over a cam 2.
  • Cam 2 is shown coupled with an oil motor 9 which is connected via hydraulic lines 3 with an oil motor 10 connected with cam 1.
  • Cam 1 is shown coupled via a chain drive 5 with a hoisting drum 4.
  • the hoisting drum may, however, be connected by other means with cam 1, such as e.g. via gear transmission, or the hoisting drum may be coupled directly with cam 1.
  • cam 1 will stand still; i.e., the oil connection between oil motors 10 and 9 via line 3 is closed and cam 2 may run freely so that when wire 7 or wire 6, respectively, is pulled, the trolley will be moved.
  • oil motors 9 and 10 are coupled together on the hudraulic side, and these will control each other's speed so that pulling on wires 6 and 7 will turn cam 1 and 2 in the same direction with equal speed, and the trolley will then stand still whilst the hoisting drum 4 is moved for lifting or lowering a load 8.
  • the valves between oil motors 9 and 10 may be closed or opened by means of radio control.
