Handle Shaft, Fifth Wheel
SAF-Holland

The handle shaft provides a manual control interface for the fifth wheel locking mechanism, allowing operators to operate the locking jaw or associated actuator with deliberate, ergonomic leverage. The shaft translates user input into the precise movement required to engage or release the kingpin, enabling safe, controlled coupling and decoupling under varying loads and environmental conditions. In addition to direct control, the handle shaft is designed to resist bending and shear forces encountered when crews re-seat the fifth wheel after hitching, improving reliability in busy terminal operations or inclement weather. The item sits within category 42774 for handle and control components used in fifth wheel systems, confirming compatibility with a range of SAF-Holland assemblies and related hardware. VMRS 059-001-013 places it within the control and handling functions of the fifth wheel domain, supporting maintenance planning and replacement part catalogs. The product's simple, robust construction minimizes failure points, reduces downtime, and supports safe operation in linehaul fleets and construction sites alike. When installing, verify proper alignment with the latching mechanism, secure fasteners to torque specs, and inspect for wear on the shaft lobes and handle interface during routine inspections.
