摘要： A hydraulic crane comprising: —a rotatable column (7); —a crane boom system comprising a first crane boom (11) connected to the column; and —an electronic control device for controlling the movement of the column and the crane boom system on of the basis of control signals from a manoeuvring unit and a calculation model for boom tip control. The control device is configured to switch from a first control mode into a second control mode when the first crane boom is about to interfere with an obstacle. In the first control mode, the control device controls the crane boom movements in accordance with an ordinary control strategy. In the second control mode, the control device makes the load suspension point (P) of the crane boom system move along the trajectory defined by said control signals while controlling the crane boom movements in accordance with an auxiliary control strategy in which the first crane boom is prevented from interfering with the obstacle.

摘要： A mobile crane includes a crane main body including a control valve which controls a supply flow rate of hydraulic oil to a main-body driving motor and a pilot-pressure control device which controls a pilot pressure supplied to the control valve. The pilot-pressure control device increases the pilot pressure at a first ratio according to an increase in an operation amount of an operation section when a counterweight carrier is an uncoupled state, increases the pilot pressure at a second ratio lower than the first ratio according to the increase in the operation amount when the counterweight carrier is a coupled state and a grounded state, and increases the pilot pressure at a third ratio higher than the second ratio and equal to or lower than the first ratio according to the increase in the operation amount when the counterweight carrier is the coupled state and an afloat state.

摘要： Disclosed are a concrete distributing device and a control method, a control system and an electrical control system for composite motion of a boom thereof. The control method comprises the steps as follows: calculating the flow of a boom pump when an operating handle sends a command; according to the command sent by the operating handle, calculating theoretical demand flow of all actuating mechanisms of the boom and theoretical control signals of all electronic proportional control valves; comparing the total theoretical demand flow of the actuating mechanisms with the flow of the boom pump; providing the theoretical control signals to all the electronic proportional control valves when the flow of the boom pump is greater than or equal to the total theoretical demand flow of the actuating mechanisms, otherwise, providing actual control signals smaller than the theoretical control signals to all the electronic proportional control valves and reducing the movement speeds of all the actuating mechanisms proportionally. In this way, when undersaturation of system occurs to the composite motion of the boom, the movement speeds of all the actuating mechanisms are reduced proportionally independent of the load difference of the actuating mechanisms, thereby ensuring that the boom can move in a motion track expected by an operator.
