Heavy Lift Analyses, Cost Tables, and Regulatory Explainers
Load charts, cost anatomy, and regulatory explainers for the estimators, engineers, and project managers who plan heavy lift work. Figures are verified and regulations are cited, so the numbers hold up when you take them into a bid.
Rooftop HVAC Helicopter Lift Checklist: Before the Aircraft Arrives
A rooftop HVAC helicopter lift checklist covering unit weights, handling instructions and curb readiness, with site protection and day-of briefing checks.
Helicopter Lift Contract Terms Contractors Should Understand
Helicopter lift contracts define minimum hours, ferry charges and delay costs. Compare billing terms and document changes before committing to a lift date.
Weather Delays and No-Go Decisions on Helicopter Lifts
Helicopter lifts stop for visibility, wind, heat and storms. The pilot decides under 14 CFR 91.3, and a hot afternoon can cost about 960 lb of hook capacity.
Sikorsky S-61: The Civil Sea King as a Heavy Lifter
The Sikorsky S-61N hook is published at 10,000 lb against a 12,336 lb empty weight. Variants, hull penalty, fire tanks and what to check on a proposal.
Rotor Wash Safety for Construction Sites
OSHA requires loose gear within 100 ft of helicopter lift points to be secured, yet outwash from a 12.6 t helicopter stays near 34 mph almost 200 ft out.
Solar Farm and Substation Equipment Placement by Helicopter
Helicopters set 500 to 800 kg solar module pallets on large roofs and small gear at roadless substations; a 200,000 lb-plus power transformer stays on a crane.
Restricted-Category Helicopters and Urban Lift Limitations
Restricted-category helicopters like the surplus CH-47D and UH-60A may not fly Part 133 loads over populated areas under 133.45(d), even with an approved plan.
When a Ground Crane Is the Better Choice
A crane wins when a pick exceeds the 28,000 lb civil helicopter ceiling, must be held while it is bolted, goes under cover, or sits beside open, firm ground.
Bell 204 and 205: The Civil Huey Lineage
The civil Huey line runs 204B, 205A-1, 212 and 214B on one airframe. A 205A-1 is certificated to 10,500 lbs external, leaving about 4,000 lbs on the hook.
Helicopter Lift Mobilization Costs Explained
Mobilization is the ferry flight, billed at the flight rate both ways. A CH-47D at $9,785 per hour runs about $173,000 on a 17.7 hour positioning leg.
Church Steeple, Spire, and Cross Placement by Helicopter
Documented US steeples run 2,600 to 23,000 lb, all inside the civil fleet. The crane still wins, because a steeple set has to be held in place while it is bolted.
