    摘要: An apparatus for detecting and protecting a telescopic oil cylinder of a crane comprises a large-cavity pressure sensor (205), a small-cavity pressure sensor (206), a controller (203), a telescopic oil cylinder (213), and a telescopic oil cylinder regulator. Further disclosed is a method for detecting and protecting a telescopic oil cylinder of a crane, in which the large-cavity pressure sensor (205) measures the oil pressure in a large cavity of the telescopic oil cylinder (213); the small cavity pressure sensor (206) measures the oil pressure in a small cavity of the telescopic oil cylinder (213); the controller (203) controls an output electrical signal according to a large-cavity oil pressure fed back by the large-cavity pressure sensor (205) and a small-cavity oil pressure fed back by the small-cavity pressure sensor (206), and, by means of the electrical signal, controls a change of the amount of hydraulic oil flowing into and out of the large cavity and the small cavity of the telescopic oil cylinder so as to regulate the oil pressures in the large cavity and the small cavity.

    摘要: The present invention relates to a device and method for controlling, or compensating for, the deformation of a crane boom (1) in lifting or placing a load (2). The deformation of a crane boom (1) is detected or measured and the detected or measured deformation is applied to a controller device (10). A target value for the position of the crane boom (1) is applied to the controller device (10) and the controller device (10) outputs signals which control or drive at least one positioner for the crane boom (1) so that the crane boom (1) is maintained substantially in its target position.

    摘要: A hydraulic power system and a work machine. The hydraulic power system includes a hydraulic oil tank (3), an engine (1), a motor (2), a first pump set, and a second pump set. The engine (1) is connected to the first pump set, and the motor (2) is connected to the second pump set. The first pump set includes a first load-sensitive pump (101), and the second pump set includes a second load-sensitive pump (201). An oil outlet pipeline of the first load-sensitive pump (101) and an oil outlet pipeline of the second load-sensitive pump (201) are connected in parallel, and a feedback pipeline of the first load-sensitive pump (101) and a feedback pipeline of the second load-sensitive pump (201) are connected in parallel by a reversing valve. Each of the engine (1) and the motor (2) is disposed to be connected to a pump set, and the first pump set and the second pump set are arranged in parallel, so that switching between two power sources of the engine (1) and the motor (2) can be implemented. Moreover, the motor (2) may be flexibly arranged without being limited to a connection to a gearbox power take-off, and the motor (2) and the second pump set are not limited to being mounted on a chassis, thereby improving mounting universality and convenience.

    摘要: [Problem] To provide an actuator control device with which desired drive control characteristics can be obtained by means of a simple operation.
    [Solution] This device performs: a reception process (S12) in which designations of a minimum operation amount and maximum operation amount of an operation unit for driving an actuator, and a maximum driving speed which is the actuator driving speed corresponding to the maximum operation amount are received; a determination process (S13, 14) in which a function representing a characteristic line that links a first point, which corresponds to the minimum operation amount and the driving speed of 0, and a second point, which corresponds to the maximum operation amount and the maximum driving speed, is stored in a storage unit as a drive control characteristic; and a drive control process in which, in response to operation of the operation unit, the actuator is driven at a driving speed corresponding to the operation amount specified by the drive control characteristic stored in the storage unit.
