IV. SYSTEM SET UP INSTRUCTIONS (CONTINUED)
C. V-22 DRIVER/EXTRACTOR
The V-22 hammer is factory fitted with its suspension assembly and is shipped
flat on its side. It is designed to receive a 7/8" multiple loop wire rope sling
properly sized and clamped to provide a factor of safety of five times the 45 ton
maximum line pull capacity of the hammer, which in turn, can be slipped over a
lifting crane hook. The V-22 hammer can be lifted from the horizontal to the
vertical without danger of excessive stresses upon its connecting parts or
structure.
1. Hanging in the air, the V-22 hammer should be hoisted, swung and
rotated to assure that the hose bundle hangs free of any loops or
entanglements.
2. Manipulating the V-22 hammer in the air during the foregoing
procedure, as well as later when setting the hammer on a pile, will be
made possible by fastening a ground handling rope to the V-22 clamp
housing before hoisting the hammer aloft.
D. V-22 JAW SHIELD
The jaw shield is generally shipped connected to the V-22 clamp assembly.
Before using the V-22 assure that the jaw shield is tightly connected (with four
hex head cap screws and lock washers) to the V-22 clamp assembly. The jaw
shield not only acts as a guide for positioning the V-22 on a standing pile, but is
also necessary to protect the jaws and the clamp assembly from unnatural
impact shock and resulting damage.
