Lift maintenance runs on cycles, not months — Braun and Ricon publish service intervals by cycle count, and a busy route bus can hit a "yearly" count in a season.
Daily pre-trip
- Cycle the lift completely — deploy, lower, raise, stow.
- Rollstop check: it must raise and hold. A rollstop that drifts is an out-of-service item, not a to-do.
- Listen for new noises — groaning hydraulics, clicking relays, grinding pivots.
The lubrication map
What gets grease, what gets dry lube, what gets nothing — greasing rollers that spec dry lube collects grit and wears them out. Follow the OEM chart for your model family.
Scheduled items
- Gas spring inspection — barriers and rollstops that sag or drift mean springs are done.
- Hydraulic fluid check — level and condition, correct type per OEM.
- Harness inspection at pivot points — chafed insulation is the classic cause of blown breakers.
- Torque checks on platform hardware.
FMVSS 403/404 background
The federal standards for platform lifts require the rollstop and interlocks to function — a deferred rollstop repair is an out-of-service item. Document your inspections; a per-lift log sheet keeps you ahead of both failures and audits.
