EXCAVATOR MOUNT
B. OPERATING THE V-2Esc SYSTEM - EXTRACTING MODE
1. Forpileextractingoperations,theV-2Eschammershouldbettedwithashackle
and an auxiliary line attached to the pad eye on the suspension assembly. The
V-2Esc hammer is clamped to a steel sheet pile to be pulled and the auxiliary line is
fastened into a lifting hole in the pile. The V-2Esc hammer is operated to extract the
pile until the pile can be easily lifted out of place exclusively by the extraction force
of the excavator. The V-2Esc hammer is then stopped by pushing the vibrate lever
to neutral. The pile is pulled out of the ground and the hammer and pile are swung
to where the pile will be stacked. The lower end of the pile is set on the ground
andtheV-2Eschammerjawsareopenedallowingthepiletohangbythelineand
shackle. The V-2Esc hammer and pile are then lowered to the ground where the line
is disconnected from the pile.
2. Thesideclampjawsareintendedtobeusedtopullthepileinsoftextracting
conditions. For best results and longer hammer life, the bottom clamp should be
used whenever possible. When using the side clamps line pull should be limited to 4
tonsandcrowdforcelimitedto4tons.Ifthesideclampjawssliponthepilestopthe
hammer and move to the bottom clamp.
Do not unclamp the jaws from the pile while the hammer is
vibrating.
3. The amount of pull which can be exerted on the V-2Esc hammer is limited by the
rating of the suspension assembly and the strength of the pile.
Do not pull in excess of the rating of the V-2Esc hammer
suspension assembly or excess stresses will be put on the suspension
assembly damaging one or more parts.
4. Always maintain proper vertical alignment between the
suspension and the pile when driving and pulling the pile.
