Abstract:
A telescoping leader system for a construction machine that includes a set of leads having a series of internal nesting segments and an extending means connecting one segment to another segment to allow for the extension of the segments one after the other to an extended position and the retraction of the segments to an internal nesting position. The telescoping leader system further includes a surface engaging member mounted within the set of leads and a pivotable mounting assembly mounted to the set of leads and adapted to adjust the position of the set of leads. A quick connecting means adapted to engage the pivotable mounting assembly is included to allow for the quick engagement and disengagement of the construction machined from the set of leads.
