How to Choose the Right Crane Body for Your Work Truck

If you’re in the market for a crane body for your work truck, you already know the stakes are high. A crane body is one of the most significant investments you’ll make in your fleet — and picking the wrong one can cost you time, money, and jobs. At Star Truck Equipment in Wharton, TX, we’ve helped hundreds of contractors, oilfield operators, and service businesses across Texas and Louisiana find the right crane body setup. Here’s what you need to know before you buy.

What Is a Crane Body?

A crane body (also called a crane service body or mechanics crane truck) combines a fully enclosed service body with an integrated truck-mounted crane. The result is a mobile work platform that lets technicians carry tools, parts, and equipment while having the lift capacity to handle heavy components on-site. These rigs are common in oilfield services, utility work, HVAC, construction, and fleet maintenance.

Step 1: Match Crane Capacity to Your Heaviest Lifts

The most critical spec is crane capacity — rated in tons at a specific radius. Don’t go by the headline number alone. A crane rated at “3-ton” may only deliver that capacity at minimum reach; at full extension, lift capacity drops considerably.

  • Light-duty (1–2 ton): Ideal for HVAC, electrical, and general contractors lifting compressors, panels, and equipment up to 4,000 lbs.
  • Mid-range (3–6 ton): Popular for construction and utility crews handling transformers, generators, and heavy machinery parts.
  • Heavy-duty (8–12+ ton): Oilfield and industrial applications — engine blocks, wellhead components, heavy iron.

When in doubt, size up. Operating near maximum capacity daily wears out a crane fast and creates safety risks. We carry Tiger Cranes and STI crane bodies in a range of capacities — call us at (979) 532-1486 to talk through your lift requirements.

Step 2: Choose the Right Truck Chassis

The crane and body are only as capable as the truck underneath them. Crane bodies add significant weight, so Gross Vehicle Weight Rating (GVWR) matters.

  • Ford F-450 / F-550: The most popular choice for medium-duty crane bodies. The F-550 chassis cab handles heavier bodies with ease and is widely available.
  • Ram 4500 / Ram 5500: Strong alternative — the 5500 offers excellent payload for larger crane body configurations.
  • Chevy Silverado 4500HD / 5500HD: Growing in popularity; good payload and cab comfort.
  • Medium-duty (Class 6–7): For the heaviest crane setups, some operators move to International, Ford F-600, or similar platforms.

Cab-to-axle (CA) measurement is also critical — it determines what body lengths will fit your truck. Be sure to specify your CA when ordering. Our team can help you verify fitment before you order.

Step 3: Steel or Aluminum Body?

Most crane bodies are built in steel for maximum rigidity and weld strength — important when the crane is bolted to the body. Aluminum options exist and save weight (which helps payload), but for crane applications where structural integrity under dynamic load is paramount, most buyers and manufacturers stick with steel. If weight savings matter to you, discuss it with your dealer before specifying aluminum.

Step 4: Compartment Layout and Body Length

Crane bodies come in various lengths — typically 9 ft to 14 ft — with compartment layouts configured to your trade. Consider:

  • Number and size of compartments: More compartments = better organization for tools and parts.
  • Drawer packages: Slide-out drawers are popular for mechanics trucks handling lots of hand tools.
  • Crane placement: The crane can be mounted at the back, mid-body, or behind the cab depending on your workflow and balance requirements.
  • Air compressor mounts: Many crane body buyers add an integrated air compressor. Plan for this upfront.

Step 5: Know the Key Brands

Not all crane bodies are built equal. Here’s a quick rundown of the major names we carry and recommend:

  • STI (Service Trucks International): STI is widely regarded as one of the best American-made service body and crane body manufacturers. Their crane bodies are purpose-built for durability and long service life — popular across Texas oilfield and construction markets.
  • Tiger Cranes: A leading truck-mounted crane brand. Tiger makes a broad range of models by capacity and reach, with strong dealer support and parts availability across the South.

Step 6: Installation and Upfitting

A crane body is not a bolt-on accessory — proper installation requires a certified upfitter who understands chassis engineering, crane mounting, hydraulic lines, electrical integration, and outrigger placement. Poorly installed crane bodies are a safety hazard and can void manufacturer warranties.

At Star Truck Equipment, we handle the full upfitting process in-house at our shop in Wharton, TX. We serve customers throughout Southeast Texas and Southwest Louisiana — and we ship rigs to buyers across the region.
