All O’ Bannon hoisting tools are designed for
ease of operation under all conditions or temperature
extremes. Electric steel alloy castings are heat treated
for optimum strength and hardness, every shank, body
and bail is magnaflux tested. Capacity ratings are determined
by tensile strength testing. The API rating applied
to each tool is based upon API Specification 8C.
Frontlock Hooks
Frontlock Hooks the automatic locking mechanism on O’Bannon
Frontlock Hooks is as easy to open as your hand. Half
concealed in the shank of the hook is a lever, which
releases the latch only when the hook is gripped to
engage or disengage the elevator bail. The latch is
hinged just above this point and extends across the
mouth of the hook. It is strong enough to ward off beams
and girts, yet sensitive enough to respond instantly
to the grip of the operator.
For those operators who prefer, the Regular hook is
supplied with a guard over the latch (cast as an integral
part of the shank).
Bearings
The main bearing in the Frontlock hook is a heavy-duty
ball thrust type, fully enclosed to keep out dirt. It
is easily lubricated through a shielded zerk fitting.
