Abrégé

The present invention relates to a crane safety management system using a vision camera, the crane safety management system comprising: an image information acquisition unit which is coupled to a crane and acquires image information; a central server which recognizes a person located in a sensing area by using image information transferred from the image information acquisition unit, and determines a state of the recognized person; and a manager terminal which receives information on the person located in the sensing area, transferred from the central server, and displays same.

The present invention relates to an oil-flushing apparatus, for an electro-hydraulic control actuator, having a structure in which a first body, having first to fifth flow paths, a detection flow path and a test-point coupling, and a fluid pressure generation part are connected, and a high-pressure flushing guide part is disposed selectively or at all times on a pipe between the first body and the fluid pressure generation part. Therefore, operational conveniences can be provided such as enabling the oil-flushing apparatus to be easily and detachably attached to a servo actuator and separated therefrom after oil-flushing, and normal operation to resume when the servo actuator and fluid pressure generation part are reconnected.

The present invention relates to a crane having an anti-vibration function, the crane comprising: a hoist unit comprising a hoist body, a wire drum which is provided in the hoist body and on which a wire is wound, a hook which is moved up and down according to winding and unwinding of the wire wound on the wire drum, a wire motor which rotates the wire drum, and a press unit which is installed on the lower portion of the hoist body and is configured to selectively carry out downward pressing or upward recovery operation according to whether a driving hydraulic pressure is supplied; a trolley which is coupled to the hoist body and moved along a guide rail to move the hoist unit; a balancing unit which includes a structure that can be coupled to and separated from a coupling rod and a structure that can come into contact with the press unit, and of which the pose is synchronized with the hook by coupling to the coupling rod; and a control unit which controls the pose of the hook by restricting the supply of the driving hydraulic pressure to the press unit and limiting the eccentricity of the balancing unit coupled to the coupling rod via the press unit.
