Patent number: 11186467Abstract: A crane includes a jib which is mounted on the crane structure so as to be rotatable about a bearing point, a counterweight arrangement which can be positioned variably in relation to the bearing point, and a hoisting cable which runs out from a hoisting winch and is guided via the jib. A counterweight adjustment device, which is coupled to the counterweight arrangement, includes a lever element mounted rotatably about a pivot point, a hoisting cable guide arranged in the course of the hoisting cable between the hoisting winch and an upper jib section, with a first deflecting pulley arrangement mounted on the jib and a second deflecting pulley arrangement mounted on the lever element, wherein the hoisting cable is guided in an alternating manner via the first and the second deflecting pulley arrangement, and a coupling element acting on the lever element and connected to the counterweight arrangement.Type: GrantFiled: December 22, 2017Date of Patent: November 30, 2021Assignee: MANITOWOC CRANE GROUP FRANCE SASInventors: Bernd Backes, Frank C.

Patent number: 10322915Abstract: A locking head is configured such that it can be moved within and along the longitudinal axis of a telescope, which comprises at least two telescope sections, by means of a telescoping device, comprising a base body, at least one releasing device which is configured to release a telescope section lock and at least one coupling device which is configured to couple a telescope section with the telescoping device. The locking head comprises an operating member which mechanically acts on the releasing device and the coupling device in order to operate the releasing device and the coupling device. The operating member comprises a first link guide for the releasing device and a second link guide for the coupling device, wherein the links for the first and second link guides extend in a single plane or in parallel planes.Type: GrantFiled: August 8, 2014Date of Patent: June 18, 2019Assignee: MANITOWOC CRANE GROUP FRANCE SASInventors: Gerhard Kaupert, Bernd Backes, Johannes Schürmann

Patent number: 7258242Abstract: The present invention relates to a mobile crane boom having a self-sufficient energy supply arranged on it for supplying hydraulic energy to at least one hydraulic load arranged on the mobile crane boom. The supply of the hydraulic load arranged on the mobile crane boom is therefore not carried out by means of a hydraulic unit arranged on the revolving superstructure of the crane, which provides the hydraulic energy to each hydraulic load via hoses, but by means of a hydraulic unit which is arranged in the upper reaches of the mobile crane boom or in the area of the linkage of any second boom section. By arranging the hydraulic unit directly on the boom, the hoses normally required for supplying the hydraulic loads can be eliminated.Type: GrantFiled: August 20, 2004Date of Patent: August 21, 2007Assignee: Terex-Demag GmbH & Co. KGInventors: Michael Irsch, Bernd Backes
