Abstract: A portable combination tool for use by truckers provides several functions in a single device. The present tool essentially comprises a telescoping tubular assembly, with the smaller diameter tube or rod being adjustably positionable within the larger tube. The smaller rod or tube attaches to the structure of an adjustably positionable tandem axle unit on a semitrailer, with the tool providing for the release of the lock pin handle of the tandem unit. A spring extends from the larger diameter handle portion of the tool, and is secured to the release pin handle of the tandem unit. The handle portion of the tool is extended to apply a tensile force to the release handle through the spring, with the driver then moving the truck and trailer slightly to release any shear frictional loads on the release pins, causing the release handle to release due to the spring tension of the tool.
