Operation TL/TLA
Step 1.
Before using any RENFROE clamp, refer to the Application Section to confirm
that the operation to be undertaken is an appropriate application for this prod-
uct.
Step 2.
Select appropriate capacity and plate thickness. The model designation, ca-
pacity, and plate thickness are stenciled on each clamp.
WARNNG: Never exceed rated capacity or use on plates that are not
within the range of plate thickness stenciled on the clamp. Lift only one
plate on each lift.
Always use a clamp with maximum plate thickness and rated capacity near
equal to the thickness and weight of the plate being lifted.
Step 3.
Inspect clamp before each lift.
WARNING: Do not use if in need of repair.
If in doubt, refer to Maintenance Section for detailed maintenance instructions
and exploded view of the clamp for part identification.
A. Check the clamp to be certain the identification and warning tags are pre-
sent and legible.
B. Do not use the clamp if the tags are missing or illegible.
C. Inspect gripping surfaces for wear and defects. Gripping surfaces must
be sharp and free of foreign matter.
D. Inspect condition of body for wear, damage and distortion, particularly in
the area of the jaw opening.
E. Inspect lifting shackle and all pins for wear and damage.
F. Lock spring must have definite amount of tension when the lock is moved
to the “Lock Closed” position without material in the clamp. Lock Pawl
must rest on body spacer sleeve.
G. On the model “TLA” the auxiliary lock button must have a positive spring
action that projects it out to engage the lock handle when the handle is
moved to the “Lock Closed” position.
H. Remove any clamp from service in need of repair.
Step 4.
The clamp is a component of the rigging used in lifting or transporting a plate.
It is important to use safe and adequate rigging. The lock is used to hold the
clamp in place until the gripping mechanism is actuated by a force applied to
the lifting shackle.
WARNING: Improper or excessively heavy rigging may interfere with
the operation of the clamp and its ability to maintain a proper position
on the plate. Never attach crane hook directly to the clamp - always use
a flexible sling between crane hook and clamp.
