Gunnebo Johnson A 7 Ton J-Latch, 471783

Johnson's exclusive J-Latch is a uniquely engineered hook latch system providing outstanding flexibility and durability. Its heavy-duty design incorporates a steel beam that positively engages a special recessed area in the hook tip. The removable two-position pin allows the J-Latch to function either as a locked bar or as an automatic spring latch. The J-Latch meets OSHA requirements and is standard equipment on Johnson crane blocks through 330 tons, all Johnson overhaul balls, and all swivels and snatch blocks with hooks. All Johnson block hooks with a J-Latch notch must be fitted with only a J-Latch to ensure proper fit. Inability to properly pin the Johnson J-Latch into its locked position could indicate distortion or permanent deformation in the hook opening. If this condition should occur remove the hook from service immediately and contact the factory.
