Model H
HORIZONTAL
SPRING-LOADED CAM
APPLICATION
The Model H is a horizontal lifting clamp intended to be
used in pairs (Fig. 39) or sets of pairs for transporting plate.
A single operator can use these clamps due to their dual
spring, which hold the cam of the first clamp in place while
the second is being positioned.
OPERATION
Step 1
Before using any Campbell
®
clamp, refer to the Application section at the beginning
of this manual to be sure the lift to be made is appropriate for the size and style of
clamp. Know the type of material to be moved before making a lift. Do not lift
plate, or plates, if they will buckle under load. Some exotic steels are too hard to
allow the teeth of the cam to sink in. This may be true of structural members and
fabricated sections.
Step 2
Select a clamp with the appropriate capacity and grip
range. The model designation, capacity and grip range
are shown on the face of the clamp (Fig;. 40).
Note: The 3T WLL for the “H” clamp is 3T per clamp.
