Abstract
Apparatus for threading together adjacent steel piles (10, 12) having male and female interlocking edges (10E, 12E). A threading device (14) is removably supported on a separate wheeled frame or dolly (16) mounted for movement along a pair of parallel horizontal beams (18) secured to opposed sides of the driven pile (10). The threading device (14) has a pile supporting slide (36) supporting the undriven pile (12) between a pair of clamping plates (48). The undriven pile (12) together with the slide (36) is moved laterally a predetermined amount upon clearance of the upper end (10C) of the driven pile (10) with the lower end (12F) of the undriven pile (12) by a lever (64) connected to a rope (61) pulled by a workman on the ground.
