Страница: 11 / 24

WARNING: The rated capacity is based on a sling angle of 60 de-
grees. Refer to Illustration D. Sling angles less than 60 degrees in-
creases load on the clamps. Refer to Operation Section, Step 3,
Chart E, for corrected loading of clamp with sling angles less than
60 degrees. Always use an adequate number of clamps to assure a
balanced load. Never exceed the rated capacity of a single clamp.
Never use on a plate or a bundle of plates that are not able to sup-
port themselves without sagging. Refer to Illustration D.
WARNING: Refer to the section on Operation and Maintenance
for the approved procedures in the Operation and Maintenance of
this product.
OPERATION
Step 1.
Before using any RENFROE clamp, refer to the Application Section to
confirm the operation to be undertaken is appropriate for the product.
Step 2.
Select appropriate capacity and jaw opening. The model designation,
capacity and jaw opening are stenciled on each clamp. Use of sling
angles under 60 degrees decreases the rated capacity. Refer to Chart E.
WARNING: Never exceed rated capacity or use on material whose
thickness is not within the range of jaw opening stenciled on clamp.
Always use clamps with maximum jaw opening and rated capacity
near or equal to the thickness and weight of the section being lifted.
