The Ford F-550 Super Duty is one of the most capable Class 5 cab chassis trucks in Texas — and when you pair it with a CM service body configured for crane mounting, you get a serious work truck ready for oilfield service, utility line work, telecommunications, and heavy construction. At Star Truck Equipment in Wharton, TX, we spec and build CM crane body configurations on Ford F-550 trucks for operators across Texas and Louisiana.

Why Ford F-550 for a Crane Body Build?

The F-550 Super Duty offers a GVWR of up to 19,500 lbs — significantly more capacity than the F-450 — which gives you room to carry a full-size crane body, a mounted crane, tools, and a payload without maxing out the truck’s ratings. That matters a lot when you’re spec’ing a crane body truck for real work:

  • Higher GVWR: 19,500 lbs vs 14,000–16,000 lbs on F-450 — more payload for crane + body + cargo
  • 6.7L Power Stroke diesel: Available with the F-550, providing the torque needed to drive PTO-powered cranes
  • Longer CA options: F-550 cab-to-axle lengths allow 11′ to 14′ crane body fitments
  • Heavier rear axle rating: F-550 rear axle handles crane body subframe loads better than lighter-rated platforms

CM Service Body Models Used for Crane Body Builds

CM SK (Service King) Body

The CM SK is CM’s flagship steel service body with high compartment walls, full-length side compartments, and a wide-open top work area. It’s one of the most popular service body platforms in Texas for crane mounting because:

  • High compartment sides provide storage for crane rigging, tools, and heavy equipment
  • Flat rear deck behind the compartments provides a stable crane mount point
  • Available in 9′, 10′, 11′, and 12′ lengths — 10′ to 11′ most common for F-550 crane builds
  • Steel construction handles the stress of crane operation and heavy crane-mounted loads

CM SRX Service Body

The CM SRX is a lighter-duty service body option — good for smaller crane applications (2–4 ton cranes) where you want to keep overall truck weight lower. Less compartment depth than the SK, but still a proven platform for light crane body work in Texas and Louisiana.

Crane Integration on CM Bodies for F-550

At Star Truck Equipment, we build complete crane body trucks — not just bodies. We integrate the crane into the CM body package on your F-550. Common crane pairings include:

  • Tiger Cranes: Our primary crane brand — mounted behind the cab or at the rear of the body; capacities from 3,000 to 12,000 lbs at various boom extensions
  • Autocrane: Another popular Texas oilfield crane option
  • Stellar: Knuckle boom cranes for utility and telecommunications work

The crane mount is welded to a dedicated subframe attached to the truck’s main frame rails — not just to the body floor. This is critical for safety and structural integrity when operating under load. We handle the full build: CM body, crane, subframe, hydraulic system, and final inspection.

F-550 Body Sizing and CA Measurements

The Ford F-550 is available in:

  • Regular Cab, 84″ CA: Takes a 10’–11′ CM body
  • Crew Cab, 60″ CA: Takes a 9’–10′ CM body
  • Crew Cab, 84″ CA: Takes a 10’–12′ CM body (the most popular crane build config)

We always verify the truck’s actual CA measurement before ordering the CM body — variations in chassis builds and upfit packages can shift these numbers.

Who Uses CM Crane Body Builds on F-550?

  • Oilfield service companies: Setting downhole equipment, pulling rods, handling tubular goods on lease roads
  • Utility companies: Electric and gas utility line crews needing a mobile service/crane truck
  • Telecommunications contractors: Tower maintenance and equipment installation
  • Construction contractors: HVAC, mechanical, and structural contractors needing a crane service truck
  • Municipalities: Parks, public works, and road crews
