Last week in the HVAC forum, members engaged in lively discussions about the timing of crane operations, particularly why early morning is preferred. Training programs that keep contracts renewed was another hot topic, highlighting the balance between technical skills and customer relations. Solar integration with heat pumps in multifamily settings was also explored, offering insights into cost-efficiency and energy savings. Additionally, there was a deep dive into commissioning checklists, emphasizing their role in coordination among subcontractors for smoother project execution.

We schedule RTU picks around 6 a.m. to beat traffic and catch calmer air — before the wind’s had its coffee; we hang a boom-tip anemometer and use a go/no-go threshold per the crane’s load chart (see https://www.osha.gov/cranes-derricks). Small caveat: some cities block noise before 7, so we get a variance and notify neighbors the day before. What wind cutoff are you using on 200’ booms?
I always do a 15‑min “dry run” the afternoon before — rig the spreader, mark set points, and cut tag-line lengths — so the morning pick is a straight lift/set with no fishing; only caveat is downtown jobs where we bump to 7 a.m. for flaggers, @wilson72. Do you pre‑back out curb bolts to shave time at height?
I pull RTU panels and economizer hoods and tag them to the skid so the pick’s lighter and catches less air, then reinstall on the roof; just confirm the lift points are still within spec and bag the openings if there’s mist — @tommill, you strip or fly them complete?
Because facilities will give us a ‘5–7 a.m.’ shutdown window, we schedule LOTO and verify RTU disconnects before first lift, and the cooler air buys a bit of load-chart margin. Only caveat: fog kills signals, so we add LED scene lights and a backup radio; @Guide, you shifting call times when the marine layer sits in?
Quick example: in our market, city noise rules and a nearby hospital helipad mean we only get a ‘5–7 a.m.’ lift slot, so we stage the day before and run a test pick with a load cell to dial in tag lines before first light. Bonus is the air’s steadier pre-thermals; after 8 a.m — the gusts get sketchy and the tag line turns into a kite — . @tommill I’ll pre-rig softeners or a spin plate for RTUs; if it’s taller than 6 ft we run twin tag lines.
