Model ASTL

Non-Locking

Both the Model AST and ASTL were developed primarily for lifting,
turning and stacking lightweight beams and structural shapes while
a constant tension is applied to the lifting shackle. The horizontal
shackle permits a beam to be lifted with the web in a near horizontal
position by placing the clamp on the load with the shackle positioned
over the web, and between the flanges. With a beam lying in a
horizontal position, and the clamp placed with the shackle
overhanging the flange, the beam can be lifted, turned 90
degrees, and raised in a vertical position.

The Model ASTL includes all of the feature of the Model AST plus
a linkage which permits the tool to be removed remotely by setting
the load down with the sling slack, then lifting the crane hook.
