摘要： A working equipment (2) comprising a hydraulically movable arm arrangement (4) for a crane, at least one electric motor (6) arranged to be powered by a battery system (8), at least one hydraulic pump (10) arranged to be operated by the electric motor (6), and a pump controller (12) configured to control the electric motor (6) and/or the hydraulic pump (10), and to monitor the current consumption (13) of the at least one electric motor (6). A plurality of actuators (14) is provided, arranged to be operated by hydraulic fluid discharged from the at least one hydraulic pump (10) and further arranged to move the movable arm arrangement (4) during a working assignment, and an equipment controller (16) configured to control movement of the movable arm arrangement (4) by generating operating signals (18) controlling the flow and/or pressure of hydraulic fluid to the plurality of actuators (14). The equipment controller (16) is arranged to determine a maximum flow limit of the hydraulic fluid from the at least one pump in dependence of a comparison of the current limit received from the battery system (8) and the current consumption (13) monitored by the pump controller (12). The equipment controller (16) is configured to compare said determined maximum flow limit with the required flow of hydraulic fluid from the at least one pump (10) needed to move the movable arm arrangement (4) in accordance with the operating signals, and if the result of the comparison does not fulfil at least one rule of a set of fluid control rules, the equipment controller (16) is configured to adapt the operating signals (18) to reduce the flow of hydraulic fluid to at least one of the plurality of actuators (14) according to at least one rule of a set of adaptation rules, such that at least one rule of said set of fluid control rules is fulfilled.

摘要： Provided is a crane that is capable of protecting a hydraulic cylinder by suppressing operation of the hydraulic cylinder when the hydraulic cylinder is in poor connection with a hydraulic circuit. A crane (1) provided with a derricking cylinder (15) configured as a detachable hydraulic cylinder is configured in such a manner that: a head side hydraulic sensor (32) and a rod side hydraulic sensor (33) are provided to the derricking cylinder (15); and when the hydraulic pressure Pr of a rod side oil chamber (15F) becomes equal to or higher than the hydraulic pressure Ph of a head side oil chamber (15E) before a prescribed time T elapses after power supply to the head side hydraulic sensor (32) and to the rod side hydraulic sensor (33) is started, and a derricking direct-acting switching valve (28) is switched, by a derricking operation tool (22B), to a state of supplying hydraulic oil to the head side oil chamber (15E), it is determined that the rod side oil chamber (15F) and the derricking direct-acting switching valve (28) are not coupled to each other via a one-side joint (16A).
