The present disclosure refers to a mobile telescopic hydraulic crane, which may include at least one service opening in a terminal portion of a telescopic section adjacent to at least one hydraulic connector, wherein said at least one service opening is configured to allow access for a hand tool from the outside of the telescopic section to establish or disassemble a hydraulically sealed connection between a flexible hydraulic pipe and associated hydraulic connector within said telescopic arm. The at least one service opening allows for a quick and simple replacement of each hydraulic pipe within the telescopic secondary arm without significantly reducing the carrying capacity and reach of the crane.
