TOWERS
The EZ Liner System is equipped with pulling towers
at front of machine. Optional rear towers are also
available. Multiple pulls can be set up quickly and are
controlled by a hand-held remote control switch.
Lateral and elevated pulling angles can be made or
changed in just a fraction of a minute.
CAUTION:
1. The 1/2 inch (13mm) tower chain is proof test-
ed to 28,000 lbs. and has a normal working
load limit of 13,000 lbs.
2. The 3/8 inch (10mm) tie down chain is proof
tested to 20,000 lbs. and has a normal working
load limit of 7,300 lbs.
IMPORTANT: The following information on towers
relates to front towers only! Although much of
this information is applicable to rear towers,
refer to Auxiliary Tower Owners Manual for
specific instructions.
To operate front towers:
NOTE: Tower operation requires use of tower pins or
tower tie bolts. The following procedure refer-
ences use of tower pins. Tower tie bolt applica-
tions appear on Page 7.
1. Swing tower to desired lateral pulling angle and pin
it to mainframe or movable crossmember. (See
Figure 7.) Tower pin can be used in any tie down
hole or along edge of machine. (See Figure 8.) DO
NOT position tower pin in front of or at rear of mov-
able crossmember as it will apply excessive stress
to crossmember locks. Instead, install tower pin
through crossmember tie down hole. (See Figure 7.)
Tower pin must be fully seated in lower pinning
hole to avoid damage to top pinning hole. (See
Figure 9.)
2. To adjust slack tower chain, grip chain on each side
of tower. (See Figure 10.) Lift out on tail of chain
until it is approximately 45 degrees from tower.
Then disengage chain from tower head and pull
chain to either increase or decrease amount of slack.
