Columbus McKinnon shackles are used in
material handling lifting and rigging application, shackles are mechanical couplers
which consist of a U shaped body closed by a pin. CM manufactures shackles
in two general configurations: an anchor pattern and a chain pattern. The
anchor pattern shackle has a more generous loop, better suited to multiple connections. Pins
are available in various styles, including a round pin secured with a cotter
pin, a screw pin secured by tightening, and a bolt, nut and cotter pin arrangement.
Super strong due to greater strength and higher ductility than carbon steel shackles
of the same nominal section size. CM shackles out perform carbon steel
shackles of equal size. Material Handling Load limits have been increased
while maintaining current design factors. CM shackles now have working
load limits from 15 ton 51% greater than equivalent size carbon shackles.
Distortion detector: A quick and effective solution for detecting distortion
in overloaded products. The distortion detector feature designed for visually
indicating whether a product has been previously overloaded. A simple straight
edge is all that's required to determine if a product should remain in service
or be replaced. To be fit for use, the marks must align with a straight
edge.
CM screw pin anchor shackles afford quick and easy removal of the screw pin,
which is secured by torque. Useful in applications where the shackle is
removed frequently. While the threaded pin can resist axial forces, it
is vulnerable to backing out, and the shackle is not reliable in material handling
applications where the pin is subjected to a torque or twisting action. Available
in three materials, in capacities up to 43 tons; alloy steel, carbon steel and
stainless steel.
Carbon Steel: Forged heat treated special bar quality steel body
with forged heat treated alloy steel pin, that meets the requirements of Federal
Spec RR-C-271D Amendment 1.
Alloy Steel: Forged heat treated alloy steel body with forged
heat treated alloy steel pin, that also meets the requirements of Federal
Spec RR-C-271D Amendment 1.
Stainless Steel: Stainless steel body and pin. Available
in anchor pattern only.
Alloy steel shackles are used for material handling overhead lifting.
Logging Trawling Shackles: Similar to screw pin chain shackles,
except that the pin has a hex head for convenience in tightening and loosening
with a wrench. Shackle body is made of drop forged heat treated steel. Pin
is made of heat treated alloy steel. Available in capacities up to 8-1/2
tons.
Carbon Anchor Shackles and Carbon Chain Shackles meets
or exceeds Federal Spec RRC-271D Amendment 1, 29 Nov 1995 . Working Load Limit
and traceability codes shown as permanent marking on body and pin. Also available
in painted, galvanized and self-colored finishes (Dacromate coating upon special
request only). All rigging shackles have alloy quenched and tempered pins.
Shackles exhibit extreme deformation before failure. Special testing and certification
including magnetic particle, proof load, and fatigue test available upon request
at time of order. Special products engineering available to meet your material
handling, special lifting, tie down, and pulling needs.
