Definitions

  • the invention relates to an apparatus for displacing a load, comprising a platform with a telescopic boom movable in the vertical plane, means mounted on the free end of the boom for removably arranging attachments such as lift forks, a winch supported by the platform for a hoisting cable guided along the boom and having a hook for the load.
  • Such an apparatus is normally used for earth-moving purposes or load displacement, for which purpose the telescopic arm is provided with an exchangeable attachment.
  • a vehicle is also known in the field as a "telescopic handler".
  • This machine is provided for this purpose with a number of suitable attachments, for instance an excavator or gripping device, forks for use with pallets, and a tackle for hoisting purposes.
  • a lift platform can further be arranged for lifting workers such as painters and the like.
  • the invention has for its object to modify the apparatus of the type stated in the preamble such that it can operate better as hoisting apparatus.
  • the apparatus is distinguished according to the invention in that a jib provided with a fixed top pulley for the cable is pivotally mounted on the free end of the boom, wherein the length of the jib is such that, as seen in the vertical plane, for all positions of the boom the vertical line along the top pulley runs clear of these mounting means on the boom.
  • the jib can be folded relative to the boom, whereby the telescopic handler can operate up to a maximum height.
  • the invention further relates to an apparatus for displacing a load, comprising a platform with a telescopic boom movable in the vertical plane, a winch supported by the platform for a hoisting cable guided along the boom and having a hook for the load.
  • Such an apparatus which can be a random crane with telescopic mast, is distinguished according to the invention in that a jib provided with a fixed top pulley for the cable is pivotally mounted on the free end of the boom, wherein the length of the jib is such that, as seen in the vertical plane, for all positions of the boom the vertical line along the top pulley runs clear of these mounting means on the boom.
  • the advantage of this embodiment is that when the telescopic boom is extended, i.e. when the sections of the boom slide apart, the hoisting cable co-displaces synchronously so that the crane operator need only concentrate on the load for hoisting, which retains the same height in a determined angular position during lengthening or shortening of the boom.
  • FIG. 1 Designated in figure 1 with the numeral 1 is the mobile platform which can be manufactured in random manner. At the four corner points the mobile platform 1 is embodied with outriggers 2 which can be retracted and extended in known manner to enable stable arrangement of the platform in the situation of use. On platform 1 is arranged a turret 3 which is embodied here with a telescopic arm 4 in the form of four pipe sections slidable into each other.
  • a coupling member 7 On the free end of telescopic arm 4, i.e. the end remote from pivot shaft 5, is arranged a coupling member 7 which in the normal course of events is used for coupling of random attachments, for instance forks for pallet use, excavators for excavation purposes and other types of attachment.
  • a jib 8 which is further elucidated hereinbelow with reference to figures 2 and 3.
  • This jib is particularly intended for lengthening boom 4 such that the boom with jib 8 can form one long boom for a hoisting attachment, this such that a hoisting cable 9 can be trained along the boom and jib 8 via guides.
  • Cable 9 is wound or unwound round a driven drum 10 and is provided on the free end with a hook 11 for a load L.
  • Figure 2 shows a detail of jib 8 which is mounted pivotally on the end of telescopic boom 4.
  • the jib 8 is in line with boom 4 and cable 9 runs round a top pulley 12 which is received for free rotation on a shaft 13 between mounting plates 14.
  • the jib is also provided with a second pivot shaft 20 which extends perpendicularly of said first pivot shaft 15.
  • Jib 8 can hereby be folded along boom 4, whereby the telescopic arm 4 with mounting means 7 for the other attachments becomes freely accessible.
  • Figure 5 shows a schematic diagram, wherein the sections of boom 4 are monitored by a roller 25 along which a magnet sensor 26 detects the rotation, i.e. the distance covered by the sections relative to the other section.
  • the generated signal from the magnet sensor is fed to an electronic circuit 27, which also receives information from a second magnet sensor 28 co-acting with a roller 29 which rolls against movable hoisting cable 9.
