Patent number: 11591190Abstract: A hydraulic crane comprising: —a rotatable column (7); —a crane boom system (10) comprising two or more liftable and lowerable crane booms (11, 13); and —an electronic control device (25), which is configured to prevent an execution of crane boom movements that would make the lifting moment of the crane exceed the maximum allowed lifting moment of the crane, and to continuously establish position information as to the prevailing position of the load suspension point (P) of the crane boom system. When the lifting moment of the crane has reached a limit value at a given level below the maximum allowed lifting moment, the electronic control device is configured to prevent the execution of any combination of crane boom movements that would increase the horizontal distance between the load suspension point and said vertical axis of rotation and at the same time allow the execution of any combination of crane boom movements that keeps said horizontal distance unchanged or reduces said horizontal distance.Type: GrantFiled: April 20, 2017Date of Patent: February 28, 2023Assignee: Hiab ABInventors: Sten Sirén, Per Gustafsson, Lars Rydahl

Patent number: 10429864Abstract: A computer implemented method for post installation adjustment of a climate system including determining a desired change of at least one radiator flow, determining a change of at least one Cv-value required to achieve the desired flow change, using a software implemented model of the system to automatically calculate a set of radiator flow changes resulting from the change of at least one Cv-value, identifying a subset of radiator flow changes from the set of radiator flow changes which have a perceivable impact on system performance, and repeating the above steps until the subset is empty. The iteration allows an operator to determine a complete set of Cv adjustments that will provide the desired radiator flow change(s) while (as far as possible) leaving other radiator flows unchanged.Type: GrantFiled: May 9, 2018Date of Patent: October 1, 2019Assignee: QSEC ABInventor: Per Gustafsson
