摘要： Mobile telescopic hydraulic crane, which is furnished with at least one service opening (48, 48') in the area of a telescopic secondary section (4), namely on its free terminal portion (42) and in particular at a suitable distance apart from the terminal portion (442) of the external tubular section (44) in the area of arrangement of at least one hydraulic connector (431) for connecting a flexible hydraulic pipe (43), which is on the other hand connectable with a hydraulic connector (432) on the free terminal portion (452) of an internal tubular bearing section (45), wherein said at least one service opening (48, 48') is available in a suitable shape and dimensions, which allow access there-through from the outside of each telescopic section (4) by means of suitable hand tool, which is required in order to establish or disassemble each hydraulically sealed connection between each flexible hydraulic pipe (43) and each belonging hydraulic connector (431) within said telescopic arm (4). Such measure then allows a quick and simple replacement of each hydraulic pipe (43) within the telescopic secondary arm (4), without significantly reducing the carrying capacity and reach of the crane.

摘要： The invention refers to a computer-controlled mobile crane, comprising a column (2), which is rotatable around its vertical axis (200'), a primary arm (3), which is pivotally connected to said column (2) and is supported by a hydraulic driving means (23), a secondary arm (4), which is optionally telescopic and is pivotally connected to said primary arm (3) and supported by a hydraulic driving means (34) and moreover furnished with attachment point (420), in which a gripping assembly (6) is attached, which is optionally rotatable by means of a hydraulic rotating unit (5), which is mounted between said attachment point (420) and said gripping assembly (6). Controlling of each movement of said column (2), said primary arm (3) and secondary arm (4), as well as of said gripping assembly (6), is performed by means of a hydraulic control unit (71), which is optionally controlled by means of a computer control unit (8) and corresponding software within each determined coordinate system (x, y, z) on the basis of detection of each position of said column (2), said arms (3, 4) and said gripping assembly (6), and is in cooperation with an optical measuring unit (9) capable to control each movement of said gripping assembly (6) towards each initial point T1 (x1, y1, z1), in which a load is located, and then from said initial point T1 (x1, y1, z1) towards each end point T2 (x2, y2, z2), where the load should be deposited. The invention also provides that said computer control unit (8) also allows avoiding of an obstacle T0 (x0, x0, z0), the presence of which could jeopardize either operation of the crane as such or reliability of transferring each load.
