Patent number: 11505435Abstract: A trolley of a crane is arranged to move along a main support structure of the crane. The trolley includes a support frame structure; bearing wheels which are fastened to the support frame structure and by means of which the trolley is arranged to move along the main support structure; and a hoisting mechanism that has a rope drum for a hoisting rope, a rope pulley arrangement through which the hoisting rope may be guided from the rope drum to a fixed fastening point on the trolley, and a hoisting member in cooperation with the hoisting rope for hoisting a load. The rope drum is supported to the support frame structure of the trolley so that the axle of the rope drum is parallel to the main support structure. The rope pulley arrangement is located, in the axial direction of the rope drum, at least partly outside one rope drum end which is on the side of said fastening point.Type: GrantFiled: September 21, 2018Date of Patent: November 22, 2022Assignee: KONECRANES GLOBAL CORPORATIONInventors: Niko Laukkanen, Atte Lähteenmäki, Teppo Lindberg, Mats Åkesson, Henri Helkiö, Henri Kokko

Patent number: 10584019Abstract: A rope drum for drawing and releasing a rope under tensile stress. Support segments are arranged to provide a number of grip sections for supporting the rope through the grip sections as a continuous spiral surrounding the rotated drum part by at least two rounds so that, when the drum part is rotated, a number of grip sections move due to the guidance of the support segments along the drum part depending on the rotation direction of the drum part towards the first end of the drum part or towards the second end. Prevention grooves or ridges together with the support segments restrict the movement of the grip sections supporting the rope on the drum part with regard to the drum part in the direction of the perimeter to a maximum that is defined by the mutual geometry of the prevention grooves or ridges and the support means.Type: GrantFiled: May 18, 2016Date of Patent: March 10, 2020Assignee: KONECRANES GLOBAL OYInventors: Ollipekka Jaatinen, Adeyinka Abass, Johannes Grönroos, Atte Lähteenmäki, Matti Pajula, Jesse Parviainen
