Definitions

  • the invention relates to a hoisting gripper for lifting a chimed drum in an upright position, the gripper being adapted to engage an upper chime of the drum and being provided with an upper arm with gripping jaw and a lower arm with gripping jaw, the two arms being pivotally interconnected and the lower arm, at its one end, carrying the upper gripping jaw and forming, at its other end, a supporting face which is adapted to rest against the side wall of a drum to be hoisted, with the upper arm, at its one end, carrying the other jaw end being provided, at a specific distance in the direction of its other end, with a point of application for a hoisting member.
  • the objective of the invention is a hoisting gripper of the above mentioned type lacking said drawback.
  • a hoisting gripper is provided with an automatic locking devicefor locking the two arms in the gripping position.
  • Said locking device may comprise a locking catch pivotally connected to the upper arm, and which is forced to the locking position by a pre-compression gear, in such a way that, as soon as a drumis hoisted, the gripper will automatically arrive in the locked position.
  • the catch may be provided with a grip for'unlockin'g. v
  • the upper arm may comprise a plurality of selectively usable points of application for the hoisting member, so
  • the supporting face and the gripping jaw of the lower arm and/or the jaw of the upper arm can have a configuration corresponding with the shape of the drum in such a way that in the gripping position the upper arm will automatically occupy a substantially radial position relative to the drum to be hoisted.
  • FIG. 1 shows in continuous lines a view in side elevation of a hoisting gripper according to the invention resting in unloaded position on a drum;
  • FIG. 2 is a top view according toFIG. l.
  • a hoisting gripper generally indicated by (l) is shown in side elevation, resting on a drum 2, of which only a minor portion is schematically indicated. Said drum is provided customarily with an upper chime 3.
  • the hoisting gripper comprises an upper arm 4 formed of two elongated plate portions and an under arm 5 formed of one elongated plate portion. The two arms are pivotally interconnected'at 6 through a boltnut connection 7.
  • the upper arm in the rest position shown comprises a substantially horizontally extending arm portion wherein two points of application 8 for a hoisting member are shown. Naturally, more points of application can be applied, if need be.
  • the left-hand end of the upper arm comprises a downwardly directed end part 9 whereon is disposed a lower gripping jaw 10, in-
  • the lower gripping arm 5 is provided, at its lower end, with a supporting face 11 and, at its upper end, with a rightwardly directed end part 12 with upper gripping jaw 13.
  • a locking catch or lower 15 between the two parts of the upper arm 4.
  • the catch is forced by a tension spring 16 to a locking position, the end face 17 of the catch resting against a corresponding face 18 at the upper end part of the lower arm.
  • an unlocking lever 19 at the other side of the pivot 14 relative to the catch 15.
  • Said tension spring not only acts as a means for moving the catch into its active position but also as a means for accommodating deviations of the chime.
  • The' lower and the upper gripping arm of approximately equal length and are slightly over half the diameter of the largest drum to be hoisted for which the hoisting gripper is designed.
  • a hoisting member will be connected to one of the points of application 8, through which the hoisting gripper can be lifted.
  • the weight of the gripper is so slight as a matter of fact that it can be easily handled manually by one man.
  • the lower arm 5 will be substantially vertical underneath the pivot 6, whereby the gripper is lowered onto a drum, the upper vjaw 13 coming to rest at some place behind the chime 3 on the cover of the drum.
  • the stop 11 will come to rest against the drum wall.
  • the upper arm 4 will thenoccupy a position as shown in FIG.
  • the upper gripping arm when approaching the gripping position if this was not yet the case originally, will occupy a substantially radial position relative to the drum.
  • the hoisting member can engage exactly above the centre of the drum, enabling it to be hoisted-in vertical position.
  • a chimed-drum gripper for holding the drum in an upright position while being hoisted comprising, a first arm means extending substantially radially of the upper end of the drum, second arm means extending substantially vertically with respect to the side wall of the drum, means pivotally connecting said first and second arm means to each other, a first gripping jaw formed on one end of the first arm means adapted to engage one side of the chime on the upper end of the drum, a second gripping jaw formed on one end of the second arm means adapted to engage the opposite side of said chime, a supporting face formed on the opposite end of the second arm means adapted to rest against the side wall of the drum, hoist engaging means formed on the opposite end portion of the first arm means, and locking means operatively connected between said first and second arm means for locking the gripping jaws in the gripping position against the drum chime, said locking means including a lever pivotally connected to said first arm means, one end of said lever engaging a portion of said second arm means adjacent said second gripping jaw, spring means biasing said
  • a gripper according to claim 3 wherein the hoist engaging means comprises a plurality of longitudinally spaced apertures formed in the first arm means.
