A. OPERATING THE V-2Esc SYSTEM - DRIVING MODE
1. First, check that the lifting capacity of the excavator, at the working radius, exceeds
the combined weight of the V-2Esc assembly and the pile. Then, lift the pile using
an appropriately sized cable between the pad eye on the suspension assembly and
theliftingholeinthepile.(Refertogures1and2).Oncethepileishangingnearly
vertical,guideitintothehammerjawsorthreadthepileintoanalreadydrivenpile.
Positionthejawsonthepile(seegure2)andclosethejawsandstartthehammer.
The vibration, coupled with the down crowd force of the excavator drives the pile. Do
not exceed the down crowd force rating.
Always use the pile handling/ safety line to attach the pile to the
hammer.
2. Cut pile handling holes 2ft. or more above center of the pile on either side of center
asrequiredtopositionpileinjawsasshowningure1.

3. The worksite needs to be level to maximize the speed of handling and driving the
pile.
4. As soon as headroom allows, move the pile to the bottom clamp to maximize driving
speed.
5. Thesideclampjawsareintendedtobeusedtostartanddrivethepileinsoftdriving
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.
6. TheV-2Escwillvibratewiththejawsopenedorclosed. Do not start
hammer with jaws open.
