The slotted design enables the latch to be seated in the hook in a way that prevents disengagement or damage to the latch, ultimately keeping loads more secure, reducing the risk of damaged equipment and enhancing operator safety.
Another feature of the design is a spring-biased safety latch that allows for installation onto the hook without spring tension, simplifying hook latch replacement in the field, according to Columbus McKinnon.
“Latches are often difficult to assemble, requiring the alignment of multiple components and screw installation while under spring pressure,” said Troy Raines, manager, rigging and chain products at Columbus McKinnon. “This can result in tired hands, lost components and multiple attempts at assembly to get components in place. With the slotted latch design, Columbus McKinnon has made this installation process easier.”
Once the latch is assembled, a user can pivot it past the hook tip to the closed position and tighten the screw. When tightened, the screw head and nut centre the latch in the hook and ensure the latch will not slip around the hook tip.
The new design is protected by patent number 11,390,493.
