Abstract

The mechanism is for maintaining balance in the pick-up of loads by hydraulic cranes or dredgers, and involves a hinged, suspended counterweight capable of balancing the supporting vessel in any position by displacement of the centre of gravity. The counterweight is also connected by rods to the front arm (4) of an articulated arm lifting mechanism (2). Via these rods (6) the centre of gravity is displaced a second time in order to balance the lifting mechanism. A final adjustment is made by the pressure in the articulated arm cylinder being transferred to an auxiliary cylinder which automatically then corrects the counterweight. The arrangement enables a 75 per cent saving in engine power for activating the crane.

Description

Le système se compose de :The system consists of:

  • 1) Un contre-poids suspendu mobile qui met en équilibre la flèche principale dans n'importe quelle position en déplaçant les centres de gravité.1) A mobile suspended counterweight that balances the main boom in any position by shifting the centers of gravity.
  • 2) Le même contre-poids est relié par une bielle à l'avant-bras et à la charge de la grue. Par cette bielle le centre de gravité du contre-poids est déplacé une deuxième fois afin d'équilibrer le balancier et charge.2) The same counterweight is connected by a connecting rod to the forearm and to the load of the crane. By this rod the center of gravity of the counterweight is moved a second time in order to balance the balance and load.
  • 3) Une correction supplémentaire est obtenue en transmettant une partie de la force dans le vérin de la flèche (ou balancier) dans un vérin auxiliaire qui donne une position optimale au contre-poids en rapport avec les charges à lever. Cette correction peut être bloquée par le conducteur de la grue.3) An additional correction is obtained by transmitting part of the force in the boom cylinder (or pendulum) in an auxiliary cylinder which gives an optimal position to the counterweight in relation to the loads to be lifted. This correction can be blocked by the crane operator.
  • 4) Comme l'ensemble rèste toujours en équilibre dans n'importe quelle position, il ne faut que de l'énergie pour déplacer une partie de la charge nominale. Cet épargne d'énergie peut avec ces types de grues, s'élever à 75 % de l'énergie repris normalement, c.à.d. un moteur de 50 CV au lieu de 200 CV pour faire le même travail.4) As the unit always stays in equilibrium in any position, it only takes energy to move part of the nominal load. This energy saving can, with these types of cranes, amount to 75% of the energy taken up normally, i.e. a 50 CV engine instead of 200 CV to do the same job.
  • 5) Cet équipement donne également l'avantage que le bras principal est en grande partie seulement utilisé en compression et n'est pas soumis à des efforts de flexion.5) This equipment also gives the advantage that the main arm is largely only used in compression and is not subjected to bending forces.
L'ensemble de la machine se compose de :The whole machine consists of:

  • 1) Une base soit fixée sur le sol ou élevé - portique - sur rails - pneumatiques ou chenilles.1) A base is fixed on the ground or raised - gantry - on rails - tires or tracks.
  • 2) Partie tournante ou plate-forme qui repose sur une couronne de giration sur la base qui permet de tourner jusqu'à 360°.2) Rotating part or platform which rests on a gyration on the base which allows to rotate up to 360 °.
  • 3) La flèche principale est montée dans des coussinets sur la plate-forme. Elle porte en porte à faux à l'avant le balancier du lest et à l'arrière le balancier du contre-poids et la bielle reliant les deux.3) The main boom is mounted in bearings on the platform. It is cantilevered at the front with the ballast balance and at the rear with the counterweight balance and the connecting rod connecting the two.

La levée et la descente est opérée par des vérins soit hydrauliques, électriques ou mécaniques.

  • 4) Le balancier monté sur la flèche à l'avant donne la possibilité de varier le rayon de travail et la hauteur.
  • 5) Le balancier porte-contre-poids et du vérin auxiliaire de déplacement du contre-poids, équilibre la flèche, le balancier et une partie de la charge.
  • 6) Avec la possibilité de correction auxiliaire (voir no.5) il est possible de déséquilibrer la grue c'est à dire, quand on doit manipuler par exemple une charge de 5 Ton nes, on peut régler le contre-poids que l'ensemble des bras est déséquilibré de 2 tonnes. Donc sans charge dans le godet, l'ensemble monte par l'excès de contre-poids et il faut tirer sur la flèche pour la faire descendre.
Lifting and lowering is operated by either hydraulic, electric or mechanical cylinders.
  • 4) The pendulum mounted on the boom at the front gives the possibility of varying the working radius and the height.
  • 5) The counterweight balance and the auxiliary cylinder for displacement of the counterweight, balances the boom, the balance and part of the load.
  • 6) With the possibility of auxiliary correction (see no.5) it is possible to unbalance the crane, that is to say, when you have to handle for example a load of 5 Ton nes, you can adjust the counterweight as the set of arms is unbalanced by 2 tonnes. So without load in the bucket, the assembly goes up by the excess of counter-weight and it is necessary to pull on the arrow to make it go down.

Quand on prend la charge, dans ce cas 5 tonnes, il faut donc seulement lever 3 tonnes.When you take the load, in this case 5 tonnes, you only need to lift 3 tonnes.

Résultat : La puissance nominale du moteur sera encore une fois diminuée de 40 % et les hautes pointes de consommation d'énergie (par exemple électricité) sont éliminées.Result: The nominal power of the motor will once again be reduced by 40% and high energy consumption peaks (eg electricity) will be eliminated.

CONCLUSIONCONCLUSION

Par ce système dans les grues de reprise au tas, déplacement, terrassement, avec benne preneuse, godet rétro ou aimant ou autre moyen de prise de charge ou lest il est possible de réduire de façon considérable la consommation d'énergie :

  • a) Comparée avec les grues mécaniques à câble ou la benne preneuse qui pèse approximativement le même poids que la charge, le système d'équilibrage équilibre compléte- ment le poids de la benne, du bras et en partie de la charge.
  • b) Comparée avec les grues hydrauliques ou le poids de la flèche du balancier et du godet s'élèvent de 4 à 10 fois le poids de la charge, la consommation d'énergie est réduite jusqu'à 90 % et la grue ne consomme que 10 %.
By this system in cranes for heap recovery, displacement, earthmoving, with clamshell bucket, backhoe bucket or magnet or other means of load taking or ballast it is possible to considerably reduce energy consumption:
  • a) Compared with mechanical cable cranes or a clamshell that weighs approximately the same weight as the load, the balancing system completely balances the weight of the grab, the arm and part of the load.
  • b) Compared with hydraulic cranes where the weight of the pendulum boom and bucket is 4 to 10 times the weight of the load, energy consumption is reduced up to 90% and the crane consumes only 10%.
