Modular Home Crane Requirements: Capacity, Access, and Cost
What crane a modular home needs, what site access it requires, and what to budget for set day. A US buyer guide to capacity, permits, and crane costs for 2026.
A modular home arrives in pieces on the back of a truck, each section sitting on a steel frame a few feet off the ground. None of it rolls onto your foundation. The crane is how the house gets from the trailer to the slab, and on most lots it is the largest piece of equipment that will ever visit the property.
Every page that ranks for this question is written by someone selling the lift or selling the home. A crane company wants the booking. A builder wants you to stop worrying about your site. This is the buyer’s version: what the crane actually has to do, what your site has to provide, and what the day costs, so you find out before you commit to a lot rather than on the morning the truck shows up.
The numbers below are US planning figures for 2026. Your builder and crane company confirm the exact specs for your project.
Why a modular home needs a crane
The modules leave the factory on a steel carrier frame that the factory reuses, so the frame goes back and the module has to come off it. A true modular home has no chassis or wheels of its own. Once it sits on the foundation it is a fixed structure, the same as a house framed on site, which means the only way to move a section from the trailer to the slab is to lift it. That job belongs to a crane.
This is the line where manufactured and modular homes split. A manufactured home, built to the federal HUD code, rides on a permanent steel chassis that stays with the house for life. That chassis lets some manufactured homes reach a slab by hydraulic trailer with no crane at all. A modular home is built to the same state and local building code as a site built house, comes off its carrier frame, and lands on a permanent foundation. The crane is not an optional upgrade for the set. It is the mechanism.
On the lift itself, the crew runs slings around the whole module, set roughly a quarter to a third of the way in from each end, and spreads the load with steel spreader bars. Sections longer than about 46 feet need three spreader bars to keep the module from flexing as it leaves the trailer.
What size crane does a modular home need?
Most standard residential modular sets need a crane with at least 100 ton capacity, and crane companies that do modular work commonly run machines from 30 to 150 tons depending on the home. Larger or harder sites move into 200 ton territory.
Two things set the number. The first is module weight. A single section runs lighter, a double section sits in the middle, and a multi story or oversized module is the heavy end:
| Home type | Typical weight per section | Crane capacity to plan for |
|---|---|---|
| Single section | 12,000 to 18,000 lbs | 60 to 80 tons |
| Standard double section | 20,000 to 30,000 lbs per section | 80 to 120 tons |
| Multi story or large | 25,000 to 40,000 lbs per section | 120 to 150+ tons |
The second thing is reach, and it is the part buyers miss. A crane cannot stand on the foundation. It sets up to one side and swings the module out over the slab, and a crane’s rated capacity drops as the boom extends. A machine rated at 100 tons close in might be rated closer to 40 tons at full reach. The number that matters is the capacity on the load chart at the exact radius your site forces, not the tonnage painted on the side of the crane. Where the crane can park relative to the foundation often decides the machine size more than the weight of the house does.
Treat the table as planning figures for evaluating a lot. The crane company calculates the real number from the module weights and the geometry of your site.
What the crane truck needs to reach your site
This is the section most buyers underestimate, and it is where a cheap lot turns expensive. Before the crane can lift anything, the trucks have to get there and the crane has to find solid, level ground to stand on.
For the route in, plan on:
| Requirement | Spec to plan for |
|---|---|
| Clear road or driveway width | 15 feet |
| Overhead clearance along the route | 14 feet |
| Clearance from power lines on the route | 15 feet |
| Maximum slope on the access way | 12 inches of rise per 20 feet |
| Bridge or culvert capacity | 15 tons minimum |
| Route must accept | a 75 foot tractor trailer |
Tight roads also need room to turn. A wide paved road over 40 feet across needs only about a 6 foot turning radius, but a road under 24 feet wide needs roughly 30 feet of radius to swing the trailer in. Narrow rural lanes and tight cul de sacs are where deliveries get stuck.
Once on site, the crane needs a clear, flat pad. Plan on a clear, flat, compacted area, and on ground that can carry serious weight. The crane and its load put substantial force through the outrigger pads, so the pad has to be well compacted soil, crushed stone, or timber crane mats. Soft or wet ground is a direct cost escalator: it means hauling in gravel or renting mats before the crane can even set up. On a typical set you also want two staging areas of roughly 30 by 60 feet, one for the crane and one for the module transporter, plus room for the set crew’s trucks.
The foundation itself has to be right before anything lands on it. Modules are set to tight tolerances, so the foundation needs to be level to within about a quarter inch across the whole footprint. Out of level foundations cause alignment problems that surface during marriage wall connection, when the two halves of the house are joined.
Overhead utility lines are the most common access problem on constrained lots. If the boom has to swing near a live line, the utility company may need to temporarily power it down or sleeve it, and that has to be arranged well in advance. OSHA bars any crane, rigging, or load from coming within 20 feet of a live power line without specific protections in place, so a line over the only viable crane position can stop the set cold.
Not sure your lot clears these hurdles? It is worth getting a site survey before you buy the land or sign the build contract, while you can still walk away. Many of the modular home builders on the site offer a site evaluation as part of quoting, which is the cheapest way to find an access problem.
Permits, OSHA rules, and who arranges them
A crane set touches several permits, and which ones apply depends on your town and your route. The lift itself needs a lift plan, normally written by the crane company, that records the load weight, the radius, and the crane configuration. Lifts near power lines or at the top of the capacity chart can require a critical lift plan with engineering calculations behind it.
The modules are oversized loads, so the transport leg needs oversize load permits from every jurisdiction on the route, and dense areas may add a police escort. If the crane has to block a public road or sidewalk, that is a separate road use or street encroachment permit, and busy areas often require traffic control flaggers on the day. Any overhead line that has to be powered down is a utility company job booked ahead of time.
OSHA sets the safety floor under all of it. Operators have to be certified through an accredited body (NCCCO is the most common) or state licensing, and evaluated on the specific machine. Signal persons need documented qualifications. The crane has to carry logged inspections, and the 20 foot power line clearance applies throughout. A reputable crane company handles its side of this as a matter of course.
Responsibility splits roughly like this:
| Task | Who handles it |
|---|---|
| Site prep, access clearing, level foundation | Homeowner or general contractor |
| Foundation level certification | Builder |
| Oversize transport permits for the modules | Builder, typically |
| Crane lift plan | Crane company |
| Operator certification, rigging, lift authorization | Crane company and operator |
| Module connection and structural work | Set crew or builder |
| Road use permits and utility coordination | Often the buyer or GC, confirm in the contract |
The gray box is permits and utility coordination. Some builders fold them into a turnkey package, others assume the buyer or GC is sorting them. Settle who files for what before you sign, because a missed road permit or an unbooked line disconnection is the kind of thing that pushes set day back a week.
When a crane is not required
A crane is not absolutely universal, but the exceptions are narrow. The realistic no crane route is a HUD code manufactured home, which sits on its own permanent steel chassis. On a slab level site with good truck access, those homes can be jacked and blocked or rolled into position without a crane.
For true modular homes the picture is different. Hydraulic jack lift trailers, which raise a deck on heavy hydraulic jacks, can place modules in specific commercial modular work, but they are uncommon for residential modular sets in the US. A single section modular on a slab with direct, level access can occasionally be set without a conventional crane, but most builders still spec a crane set in the contract.
So when a salesperson says you will not need a crane, the question to ask is not about the crane. It is whether the home is built to state and local building code or to HUD code. That classification, not the name on the brochure, decides how the house gets onto the ground. For more on where that line falls and what it costs you, see the hidden costs of prefab homes.
What set day looks like, hour by hour
A standard double section home is set in a single day, usually 6 to 10 hours from the crane arriving to a weathertight shell. A multi story or large home can run into a second day. Here is how a typical day runs:
| Time | What happens |
|---|---|
| 6:00 AM | Crew arrives, inspects the site and foundation |
| 7:00 AM | Crane arrives and sets up, about 45 to 60 minutes on outriggers and leveling |
| 7:30 AM | Modules are unwrapped and rigged |
| 8:30 AM | First module lifted and set on the foundation |
| 10:00 AM | Second module set, marriage line prepared |
| 11:30 AM | Marriage wall connection completed |
| 1:30 PM | Upper modules lifted and stacked, if multi story |
| 3:00 PM | Roof system raised |
| 4:30 PM | Weatherproofing started |
| 6:00 PM | Site cleaned up, home is dried in |
Each lift takes roughly 20 to 45 minutes. The set crew is 4 to 10 specialists, usually the manufacturer’s own team rather than general labor, and they handle the rigging, the seams, the roof fold, and the bolted structural connections that turn separate boxes into one house.
Weather runs the schedule more than anything you can control. Most operators stop lifting when sustained winds reach 20 to 30 mph, because a module hanging from a boom acts like a sail, and they stand down entirely for lightning. Build a day or two of slack into the plan so a windy morning does not cascade into your whole finishing schedule.
For your part on the day: have someone on site to take delivery, keep the access route clear of parked cars, have any utilities disconnected or dropped as arranged, and make sure the foundation has passed inspection before the trucks roll in.
What to budget for the crane and set crew
Crane time for a modular set commonly runs $350 to $550 per hour for a 100-ton machine, or about $2,500 to $6,000 for a day in the 100 to 200 ton class. Step up to a 200 or 300 ton crane for a large or awkward set and the rate can clear $10,000 a day.
The crane is one line on a longer bill. A realistic all in budget includes:
| Item | Typical range |
|---|---|
| Crane and operator | $2,500 to $6,000 per day (100 to 200 ton) |
| Mobilization and travel | $500 to $1,500 |
| Rigging and crew support | $1,000 to $2,500 |
| Set crew labor (4 to 10 workers) | $5,000 to $20,000 for the day |
| Oversize transport permits, escort if needed | $1,500 to $3,000 |
| Street encroachment permit, if required | $500 to $2,000 |
| Traffic control flaggers, if required | $1,000 to $3,000 |
| Temporarily powering down a line | $500 to $1,500 |
| Crane mats or gravel pad for soft ground | site specific, can be steep |
For a standard double section on a lot with decent access, set in one day, most buyers land between $8,000 and $15,000 all in. Soft ground, a bigger crane, a police escort, or a multi story home can carry that past $20,000, and a genuinely awkward urban or remote site can reach $30,000 or more.
Watch the cheap headline rates. A quote that names only the crane day, with no set crew, mobilization, or permits, is quoting one line of the invoice. The honest comparison is the all in number for your specific site.
The cleanest way to handle the whole thing is to ask the modular builder to quote the crane and set as a single turnkey line item rather than booking the crane yourself. A builder with an established crane relationship usually gets a better rate and, more to the point, takes on the coordination risk for sizing, permits, and scheduling. If anything goes wrong on the day, it is their problem to solve, not yours.
Crane logistics are one of the clearest signals of whether a builder runs a tight operation. Compare the modular home builders who spell out the set process and price it upfront, and browse modular homes for sale to see how the houses you are weighing actually get to the ground.
Frequently asked questions
Do all modular homes need a crane?
Almost all true modular homes need a crane. The modules leave the factory on a steel carrier frame that has to go back, so each section arrives held off the ground with no wheels or chassis of its own. A crane is the only practical way to lift the module off the frame and set it on the foundation. The exception is HUD code manufactured housing, which rides on a permanent steel chassis and can sometimes be placed by hydraulic trailer without a crane. If a builder tells you no crane is needed, confirm whether the home is built to state and local code (modular) or to HUD code (manufactured), because that classification decides the set method.
What size crane is needed for a modular home?
Most standard residential modular sets need a crane with at least 100 ton capacity, and crane companies serving modular work commonly run machines from 30 to 150 tons. A single section home can sometimes be set with 60 to 80 tons, a standard double section typically needs 80 to 120 tons, and multi story or heavy modules can require 150 tons or more. Capacity is not driven by weight alone. A crane has to set up outside the foundation and reach over it, and its rated capacity falls sharply as the boom extends, so a 100 ton crane at full reach may be rated closer to 40 tons. The crane company sizes the machine from a load chart at the exact radius your site requires.
How much does a crane cost to set a modular home?
Crane time for a modular set commonly runs $350 to $550 per hour for a 100-ton machine, or roughly $2,500 to $6,000 for a day in the 100 to 200 ton class. The crane is only part of the bill. Once you add the set crew, mobilization, rigging, and any permits, most standard double section sets land somewhere between $8,000 and $15,000 all in for a single day with good site access. Difficult access, soft ground, a larger crane, or a multi story home can push the total past $20,000. The cleanest way to handle this is to ask the modular builder to quote the crane and set as a single turnkey line item rather than booking it yourself.
How long does it take to set a modular home with a crane?
A standard double section home is usually set in one day, roughly 6 to 10 hours from crane setup to a weathertight shell. The crane itself takes 45 to 60 minutes to set up on its outriggers and level, then each module is lifted and placed in about 20 to 45 minutes. Multi story or large homes can run into a second day. Weather can stop work at any point: most operators halt lifting when sustained winds reach 20 to 30 mph and stand down completely for lightning, so build a day or two of contingency into your schedule.
Can a modular home be placed without a crane?
Rarely, and usually not for a true modular home. The module arrives on a carrier frame the factory reuses, so something has to lift it off and onto the foundation, and that something is almost always a crane. Hydraulic jack lift trailers can place certain modules in specific commercial situations, but they are uncommon for residential modular work in the US. The no crane route applies far more often to HUD code manufactured homes, which sit on a permanent chassis and can be jacked and blocked onto a slab. For a true modular home, plan on a crane and prepare the site for one.
Who arranges the crane and the permits on set day?
The crane company supplies the crane, the certified operator, and the lift plan. The manufacturer or its set crew handles rigging, module connection, and the structural work once each section lands. Site preparation, a level foundation, and clearing access are the homeowner or general contractor's responsibility. Permits and utility coordination are the gray area: some builders fold them into a turnkey package, others leave them to the buyer. Settle who files for oversize transport permits, road use permits, and any temporary line disconnection before you sign the build contract, not in the week before set day.
