SAF-Holland hosted a session dedicated to the maintenance of fifth wheels at the Australian Trucking Association’s (ATA) 2025 Technology and Maintenance Conference (TMC25) earlier this week.
At this session, the manufacturer delivered a clear message – while the fundamentals of fifth wheels haven’t changed much in decades, attention to maintenance, correct adjustment and operator training remains critical to safety and reliability.
SAF-Holland Technical Officer, Ross Molloy, noted that modern fifth wheels may look familiar, but years of refinement have tightened tolerances, improved castings and enhanced sensor reliability.
“All the moving parts underneath are basically the same as 40 years ago,” he said. “What’s changed is how we manufacture and maintain them.”
The Holland FW351 and FW331 models have seen their ratings increased to 210kN, supported by upgraded castings and tighter pin-and-bore tolerances that reduce vertical movement from day one.
Both models now feature refined pocket liners and optional bolt-on feet, expanding mounting flexibility beyond the traditional welded base.
The discussion also highlighted the ongoing evolution of electronic lock indicator technology, now offered as the ELI-te system – a reliable, plug-and-play 12-volt setup that provides both visual and optional audible alerts to verify coupling integrity.
“It’s there to assist the driver, not replace good practice,” said Molloy.
“Drivers still need to get out, look, and perform a tug test.”
SAF-Holland’s focus on training and inspection was evident throughout the session. Attendees were reminded that improper lubrication, over-tight jaw adjustment or neglecting wear tolerances can quickly lead to premature component failure or worse.
The company provides USB toolkits with service bulletins, maintenance checklists and inspection guides to help workshops stay compliant and confident in their fifth wheel servicing.
