XA11992L
Secondary Lock S/A
SAF-Holland

Secondary locking device within the latch actuation chain reinforces safe operation by preventing inadvertent release of the primary locking mechanism during transit and vibration. The component is identified in the fleet's catalog by VMRS code 059-001-010, marking its function and enabling standardized service documentation. Its attributes include a component family designation in the product attributes, which supports targeted replacement in maintenance workflows. Heavy-duty construction and tight tolerances ensure reliable engagement and retention under repeated cycles. Proper integration with the seizing or pawl assembly gives the operator predictable control and reduces the risk of uncoupling caused by mechanical fatigue or improper user action. Installation requires alignment with existing latch geometry and adherence to torque and timing recommendations. It is compatible with common locking assemblies used in heavy-duty couplers and conforms to standard frame and bracket interfaces within the 42784 category segment, supporting fleet-level interchangeability and streamlined stocking.
