Claim Text:
1. A method of controlling relative telescoping extension of multiple telescoping assemblies connecting a main frame of a slipform paver to a side frame member of the slipform paver, the telescoping assemblies being extendible and retractable to adjust a frame width of the slipform paver, each telescoping assembly having a telescopic lock associated with the telescoping assembly, comprising: (a) applying a common telescoping force across first and second telescoping assemblies to widen or narrow the frame width of the slipform paver; (b) monitoring extension of the first telescoping assembly; (c) monitoring extension of the second telescoping assembly; and (d) locking at least one of the telescopic locks for the first and second telescoping assemblies so as to determine which of the telescoping assemblies is allowed to telescope under the application of the common telescoping force.
