Cranes on the farm: bins, trusses and spring road limits
Farm crane work around Sioux Falls means long drives on county roads, big open yards and overhead lines. Spring road limits can decide the date more than the job does.

Can a crane get to my farm in the spring?
Often, but plan around frost. South Dakota can restrict loads on roads anytime from February 15 through April 30, and heavy cranes may need a longer route or a later date. Send the road the crane will use and whether it is gravel, and the operator will check the current restrictions before booking.
- Spring load restrictions can apply from February 15 through April 30.
- Post-frame trusses and bin roof sections usually fit a 40 to 60 ton boom truck.
- Farm yards often have overhead lines; OSHA requires 20 feet of clearance up to 350 kV.
- A 60-ton boom truck day runs about $1,800 on published rates, before fuel and travel.
The road in matters first
A crane has to reach the yard before it lifts anything. South Dakota can put spring load restrictions on state roads anytime from February 15 through April 30, based on frost and thaw, and counties and townships post their own. A heavy crane, or the truck hauling its counterweights, may need to go the long way around or wait until limits come off.
When you send the job, include the road the crane would use, whether it is paved or gravel, and any weight-posted bridge on the way. The operator checks the current map before setting a date.
Common farm lifts
- Post-frame trusses. Shops and machine sheds with long clear spans. A 40 to 45-ton boom truck sets most truss packages in a day.
- Grain bin roofs and rings. Many crews assemble the roof on the ground and lift it with a crane, then jack the bin. The dealer has the weights.
- Equipment and tanks. Dryers, fuel tanks and machinery set on pads or moved between yards.
- Steel and hangars. Bigger steel buildings and long trusses move up to 60 tons or more.

Lines, ground and wind
Farm yards are full of overhead lines running to bins, dryers and shops. OSHA keeps a crane boom at least 20 feet from lines up to 350 kV unless the utility de-energizes or insulates them, so call the co-op early if a line crosses the work area.
Gravel yards hold up well. Thawing fields and low spots do not, and OSHA puts the job of providing firm ground on whoever controls the site. Point out any buried tanks, drain tile or fresh fill. Open ground also means wind, and a bin roof catches a lot of it, so lifts often start early in the day.
Farm lift costs
On published boom truck rates:
| Job | Machine | Rough cost |
|---|---|---|
| Small tank or equipment set | 26-ton boom truck, 4 hours | $660 |
| Truss day on a machine shed | 40 to 45-ton boom truck, 8 hours | $1,640 |
| Bin roof or long-span steel | 60-ton boom truck, 6 hours | $1,800 |
Add the fuel surcharge and travel. A farm an hour from the crane yard can add two billed hours on portal to portal billing, so lining up work with a neighbor the same day helps.
Common questions
How much does a crane cost for a post-frame building?
A 40 to 45-ton boom truck at $205 an hour for a full 8-hour day of trusses is about $1,640 on published rates. Longer spans or a big shop may need the 60-ton at $300 an hour with a 6-hour minimum. Travel from the yard is billed too.
Can a crane set a grain bin roof?
Yes. Many crews build the roof on the ground and have a crane set it on the first ring, then jack the bin up ring by ring. Give the operator the bin diameter and the roof weight from the dealer.
What if the yard is soft after the thaw?
A crane on soft ground needs mats or a firmer spot. If the yard is wet in April, a later date or setup on the driveway may save the day.
