Patent number: 10029892Abstract: A hoisting rope arrangement in a trolley moving along a main girder of a crane and driven by an outside mechanism is provided. Both sides of the trolley are provided with successive rope pulley pairs located at a distance from one another in a longitudinal direction of the trolley and, below these, sheaves situated in a hoisting member, whereby on both sides of the trolley, a first hoisting rope is led from a first end of the main girder of the crane via one rope pulley of a first rope pulley pair down to the sheave and therefrom via an other rope pulley to a second end of the main girder, and a second hoisting rope is led from the second end of the main girder via one rope pulley of a second rope pulley pair down to the sheave and therefrom via an other rope pulley to the first end of the main girder.Type: GrantFiled: February 27, 2014Date of Patent: July 24, 2018Assignee: KONECRANES GLOBAL CORPORATIONInventor: Esa Ojapalo

Patent number: 9708163Abstract: A crane, particularly a rubber-wheel container crane includes a frame which has, on opposite sides of its lower part, main beam structures at both ends of which, i.e. in the lower corners of the crane, there are two successive rubber wheels or wheel arrangements through which the crane is supported by its moving carrier. These wheels are supported by the main beam structure rigidly and in an unsuspended manner.Type: GrantFiled: June 26, 2014Date of Patent: July 18, 2017Assignee: KONECRANES GLOBAL CORPORATIONInventor: Esa Ojapalo

Patent number: 9695555Abstract: The invention relates to a method to form a rail joint, in which staggerings (6, 7) corresponding to each other are made in joinable solid-profile rail ends (4, 5) of parts (2, 3) of a rail (1) so that when a completed rail joint is viewed from above the rail heads bond; both rail ends are secured to a corresponding mounting; the rail ends secured to the mountings are brought against each other whereby said bonding is established; and the mountings that are against each other are secured to one another. The staggerings (6, 7) are made in such a manner that the lower edges (4a, 5a) of the rail ends (4, 5) are left substantially unstaggered whereby the staggerings extend from these lower edges towards the top surfaces or the rail ends; and the rail ends (4, 5) are welded by their lower edges (4a, 5a) at their entire width to their mountings (8, 9). The invention also relates to a rail joint made by this method.Type: GrantFiled: January 30, 2014Date of Patent: July 4, 2017Assignee: KONECRANES GLOBAL CORPORATIONInventors: Kari Mäenpää, Esa Ojapalo
