OUTER TUBE CLAMP ASSEMBLY INSPECTION INSTRUCTIONS
All SwapLoader hooklift hoists come equipped with an outer tube clamp assembly located on the
bottom of the outer tube at the opening where the jib telescopes in and out (see illustration
below). On SwapLoader 400 series hoist models the outer clamp assembly is fixed in height.
INSPECTION
The illustration below is a typical hoist clamp assembly for the SwapLoader 400 series hoist
models. For optimum performance out of your SwapLoader SL-400 hooklift the gap between
the top of the jib horizontal tube and the top inside surface of the outer tube should be kept
between 1/16" to 1/8" (see Section View A-A below). When a gap greater than 1/8" exists,
since the clamp assembly has a fixed elevation, inspect the clamp liner, clamp plate, and
fasteners for excessive wear or damage (see Section View A-A below). Replace parts as needed
to bring the outer tube clamp assembly back to recommended specifications (see Drawing No.
42H04 in the Parts List pages of the manual).
