12' 60° Roof Cap Ground Control
Ground control comes standard on 12' 60° Bulk Feed Tanks. Ground control is optional on all 45° Bulk
Feed Tanks. Ground control components come fully assembled for the convenience. The ground control
is shipped with the arm secured for safety and shipping purposes. The wire and retaining tie are intended
for shipping use only.
Refer to control arm and ground control details
for component part assembly. The peak cap
latch hook, located opposite the cap hinge, latches over the cap hold-down bracket. (Ref# 20, ground
control detail
). One end of the ground control chain is secured at the counterweight arm
with a cotter pin.
The chain is passed up and over the cap, through the grommet on the
pivot arm and through the roof eave bracket (BLK-11950), then continues down the side of the tank.
