We run four crews on 12-hour rotations; I’ve started slotting 25-minute micro-sessions at lineup (0545) and before crib (1730) to cover LOTO, spotter protocols, and the new 793F telematics without stalling the pit. If you’ve balanced certs and production better — especially nights — how are you rotating operators so the shovel, dozers, and dispatch screens never sit cold?
Do you have one cross‑qualified rover who can start 15 minutes early and hot‑seat the shovel during your “1730” and 0545 blocks, then slide to a dozer and babysit dispatch until the op returns? That’s how we keep nights covered and still hit the 25‑minute bites, and we train them on the 793F telematics so they can answer quick in‑cab questions. If headcount’s tight, we’ve pulled a utility hand into the rover slot on Sundays to avoid cold screens.
Pair your 25‑minute blocks with a mini‑TPM on the shovel so it’s not “cold” for nothing — at 1730 we do teeth/GET check and slew ring temps while dispatch holds one truck string and reroutes the rest to a short queue. Nights, we flip it to “0545” during plant reset so trucks are naturally pausing and a dozer tidies the floor for 10 minutes; , dead time without a task drives me nuts. Do you have a predictable maintenance or plant changeover window you can anchor the sessions to?
, nights were killing us until we added a dedicated ‘swing seat’ per shift — a trainer-level op who hot-seats the shovel for 12–15 minutes and then a dozer while you run the 0545 and 1730 refreshers, so dispatch never idles a string. We mirror the dispatch client on a rugged tablet for the trainee so they still see truck flow; small caveat, you’ve got to protect that swing from getting sucked into breakdowns. @timothy2584, have you tried a swing seat or are you covering with fuel/lube only?
We switched the 1730 block to a rolling circuit — 8–10 minutes at the shovel cab, then dozer, then dispatch — so only one seat pauses at a time and the queue keeps moving… Dispatch just biases assignments to the live unit for two cycles while I’m at the cab; total hit per asset is about 9 minutes instead of 25, but you need a trainer with a radio and a posted order. @timothy2584, think that circuit would slot into your nights?
