Description
Hydraulic Ram, Punches, and Dies
The hydraulic punching action is accomplished with a
single-acting ram. Hydraulic pressure advances the ram
to drive the punch and an internal spring retracts the
ram after the hole is made.
The punches are designed to punch through solid and
laminated bus bar. Punches larger than 8mm have a
spring-loaded centering pin for precise alignment. Two
sets of dies are supplied with the bus bar punch: dies
with a black finish for punching laminated bus bar, and
dies with a bright zinc finish for punching solid bus bar.
Alignment Table
The alignment table is adjusted vertically to support the
bus bar at the working level of the punch. The adjust-
able handle allows the top plate to be moved from side
to side.

Bus Bar Punch System
The bus bar punch operator can set precise hole
locations using the alignment top plate, the side align-
ment guide, and the depth stop. These have scales to
indicate the distance from the edge of the bus bar to the
center of the hole.
Hydraulic Pumps (Electric/Manual)
The bus bar punch is intended to be used with any
Greenlee hydraulic pump capable of developing 10,000
psi (690 BAR). See the manual supplied with the pump
for specific instructions concerning its use.
X-Y Table (Optional)
An optional X-Y Table is available for quick set-up and
repetitious punching of standard 2-bolt and 4-bolt hole
patterns. See catalog number 37736.
