Definitions

  • the two balancing arms are separated from the double roller blocks, and only one of the two load hooks with its bearing block is inserted into the corresponding bearing connection on the intermediate rocker of one of the two single roller blocks. This reduces the weight of the bottom block to about half and is now only 17 t.
  • a maximum weight of 500 tons can be lifted in this way.
  • FIG. 2 shows a bottom block variant composed of a part of the components of FIG. 1 for a maximum load capacity that is approximately half as large. For this purpose, only one of the two double roller blocks 4a, b from FIG. 1 is used.
  • connection of a load hook 2a with a single roller block 1 a can also take place without the interposition of an intermediate rocker 3a.

Abstract

L'invention concerne un ensemble de moufles pour une charge maximale donnée, constitué de moufles inférieures à puissances de levage variables, destinées à une grue, notamment une grue de fort tonnage, cet ensemble comprenant les éléments suivants : quatre moufles individuelles (1a-d) avec chacune plusieurs poulies ; deux crochets de levage (2a, b) ; deux bielles oscillantes intermédiaires (3a, b) qui permettent chacune de regrouper deux moufles individuelles (1a, b ou 1c, d) en une moufle double (4) ; une unité oscillante de compensation (5) comprenant deux bielles oscillantes (6, 7) reliées entre elles par un bloc d'articulation (8) comportant un axe de pivotement vertical et au moins un axe de pivotement horizontal. L'une des bielles oscillantes (6) peut être mise en liaison avec les deux bielles oscillantes intermédiaires (3a, b) au moyen d'une première articulation tournante horizontale (10a, b), et l'autre bielle oscillante (7) peut être mise en liaison avec les deux crochets de levage (2a, b) au moyen de deux blocs-supports (11a, b) dotés d'une deuxième articulation tournante horizontale (12a, b). Les crochets de levage (2a, b) tournent autour d'un axe de rotation vertical dans leur bloc-support (11a, b) respectif, et dans au moins une des bielles oscillantes intermédiaires (3a, b) se trouve un raccord de support (13) dont les cotes de raccordement correspondent à la deuxième articulation tournante horizontale (12a, b).
