5.2-6 Clamps without Arms
Customer-supplied arms can be welded to the vertical
bases that connect the Clamp's parallel sliding arm bars.
Sliding arm assemblies must be removed from the Clamp
to accomplish this procedure.
1 Remove the sliding arm bar assemblies as described
in Section 5.2-1.
2 Using approved welding procedures, weld the custom
arm to the vertical base connecting the sliding arm
bars.
CAUTION: Weld fabricated arms to the vertical arm
bases only. Do not weld or bolt special-built arms or
forks directly to the arm bars. Surface flatness on the
arm base must remain within .010 in. (0.25 mm).
3 Assure that the sliding arm bars remain parallel over
their entire length, using the dimensions shown.
4 For reassembly, reverse the above procedures with the
following exceptions:
• Check that the arms slide free manually.
Arm bar base material is AISI C-1020 steel with
the following specifications:
Tensile Strength – 61,000 psi
Yield Strength – 43,000 psi
Carbon Content – 23 % Max.
WARNING: Use a certified welder and
proper welding procedures when welding
customl arms to the sliding arm bases.
