Abstract

L'invention a trait aux appareils de levage. Elle a pour objet une commande de synchronisation automatique de deux dispositifs de levage de grue travaillant en compoundage, dont chacun est muni d'un entraînement hydraulique qui se compose d'une pompe et d'un moteur hydrauliques réglables. Aux canalisations haute pression 12, 15 des entraînements hydrauliques 3, 10, 6, il sont raccordés les cylindres de réglage 19, 20 des moteurs hydrauliques 3, 6 par l'intermédiaire dune soupape 4/2 voies 14, de telle sorte que lors du soulèvement, la canalisation haute pression 12, 15 d'un entraînement soit reliée au cylindre de réglage 19, 20 du moteur hydraulique associé, et au cylindre de réglage 20, 19 de l'autre moteur hydraulique lors de l'abaissement. Application : grues travaillant en compound.The invention relates to lifting devices. Its object is an automatic synchronization control of two crane lifting devices working in compounding, each of which is provided with a hydraulic drive which consists of an adjustable hydraulic pump and motor. To the high pressure pipes 12, 15 of the hydraulic drives 3, 10, 6, the adjusting cylinders 19, 20 of the hydraulic motors 3, 6 are connected by means of a 4/2 way valve 14, so that when lifting, the high pressure line 12, 15 of a drive is connected to the adjustment cylinder 19, 20 of the associated hydraulic motor, and to the adjustment cylinder 20, 19 of the other hydraulic motor during lowering. Application: cranes working in compound.
