A loading arm includes a stand pipe, a coupler configured to be connected to a tank to deliver a product, and a pipe assembly having a first pipe end pivotally coupled to the stand pipe and a second pipe end pivotally connected to the coupler. The pipe assembly includes a pivot joint disposed between the first pipe end and the second pipe end such that the pipe assembly is movable between a retracted position and an extended position. A linkage assembly has a first portion connected to the pivot joint and a second portion connected to the stand pipe. The linkage assembly is operable to allow for the positioning of the coupler at any of a plurality of points corresponding to the pipe assembly being positioned between the retracted position and the extended position. The linkage assembly is fully supported by the stand pipe such that movement of the pipe assembly does not require manipulating the weight of the linkage assembly.
