Definitions

  • the present invention relates to a hoist and load handling with directional distributor arrow, comprising a pylon with a rotating pivot, a mounted boom in articulation at the top of the pylon by an axis of rotation horizontal arranged at the first end of the said arrow, an arrow lifting device and a restraint assembly arrow comprising a punch, at least one sling of boom retainer and a mobile counterweight connected to the boom by said restraining sling.
  • cranes are usually used horizontal directional distributor arrow, on which slides a trolley serving as a guide to ways of suspension of charges.
  • the lift cranes have the advantage, for example compared to horizontal boom cranes, to be able to bring loads at greater heights, at tower heights comparable.
  • the effort of the dead weight of an arrow operating in workable mode of work varies considerably between arrow positions close to the horizontal and position raised close to the vertical. That's why this type of crane is sometimes equipped with a mobile counterweight, whose position varies depending on the angle that the arrow with the horizontal.

  • the position of the arm is slaved to the angular position of the boom, attached to the other end of the swingarm, such so that the counterweight is close to the axis of rotation of the pylon when the arrow is raised, and spreads in a pendulum motion when the arrow tilts horizontally.
  • This device assists the operation of lifting for important lifting angles.
  • This kind of crane always requires a lifting device to high torque.

  • the counterweight is mounted rolling on straight spars of the platform, which have a slight slope directed towards the axis of pylon.
  • the counterweight is connected by a tie rod to the boom, via a pulley, so that deviate from the pylon when the arrow falls towards horizontally and to get closer to the pylon when the arrow is raised.
  • This device makes it possible to compensate the moment of the dead weight of the boom on the pylon structure but the lifting requires a mechanism providing a very important.
  • Port-type cranes can also be used. with articulated horizontal directional distributor arrow, moving the load, moving away respectively bringing it closer to the pivot axis of the crane by deployment, respectively refolding the arrow.
  • the moment of the own weight of an arrow of this type varies considerably between the extended position of the arrow and the folded position towards the pylon. He is difficult to balance these variations of effort by a single counterweight mobile.
  • Document DE 1 260 733 describes a crane of this type and proposes to reduce or even eliminate the counterweight and use a distribution reminder cable, attached to the end of the dart tip, cooperating with a cable arrow retainer acting on the end of the counter-dart, via punches and return pulleys, these two cables being operated by winches.

  • the arrow consists of an arrow foot, the first of which end is mounted in rotation at the top of the pylon, and a dart mounted in articulation on the second end of the foot of arrow, this dart being delimited by this articulation in two parts, namely a counter-dart and a dart tip.
  • the counter-dart and the part of foot of arrow near this joint are consistent so that the foot of the arrow and the dart can come into alignment in a work-up mode, which increases both the horizontal reach and the height maximum under hook of the machine.
  • This device uses a distribution cable not held by guides on a great length when the arrow is almost completely deployed, resulting in stability problems in rotation and in distribution under load and headwind.
  • Applicant's patent application WO 02/04336 describes collapsible lifting gear and tower cranes, with arrows adjustable, articulated, liftable and tilting darts.
  • the part of the neighboring arrow foot the dart and counter-dart have shapes conjugates allowing the dart tip to come into aligned with the boom foot in working mode lift.
