Title (EN) ANTI-TWO-BLOCK SENSING SYSTEMS
(FR) SYSTÈMES DE DÉTECTION ANTI-RAPPROCHEMENT DE MOUFLES
Abstract:
(EN) Various hoisting systems with anti-two-block sensing devices are provided. In one embodiment, an apparatus includes a crane having a hoisting line and an anti- two-block sensing device installed about the hoisting line. The anti-two-block sensing device includes an upper chandelier, a lower trigger assembly suspended from the upper chandelier, and a detector positioned to detect movement of the lower trigger assembly with respect to the upper chandelier. The lower trigger assembly can include two plates each having a hoisting line aperture and a slot that allows transverse installation of the plate about the hoisting line. Further, the two plates can be positioned such that their slots are offset from one another and the plates cooperate to fully surround the hoisting line. Additional systems, devices, and methods are also disclosed.
(FR) La présente invention concerne divers systèmes de levage pourvus de dispositifs de détection anti-rapprochement de moufles. Dans un mode de réalisation, un appareil comprend une grue équipée d'un câble de levage et d'un dispositif de détection anti-rapprochement de moufles installé autour du câble de levage. Le dispositif de détection anti-rapprochement de moufles comprend un chandelier supérieur, un ensemble déclencheur inférieur suspendu au chandelier supérieur et un détecteur positionné de façon à détecter un déplacement de l'ensemble déclencheur inférieur par rapport au chandelier supérieur. L'ensemble déclencheur inférieur peut comprendre deux plaques présentant chacune une ouverture de câble de levage et une fente qui permet une installation transversale de la plaque autour du câble de levage. En outre, les deux plaques peuvent être positionnées de telle sorte que leurs fentes sont décalées l'une de l'autre et que les plaques coopèrent de façon à entourer complètement le câble de levage. La présente invention concerne également d'autres systèmes, dispositifs et procédés.
