A boom crane truck is a versatile commercial truck with a hydraulic crane and flatbed body, built to transport materials and lift heavy loads at the same job site without calling in separate equipment. Whether you're a contractor pricing out your next fleet addition or a fleet manager looking to sell an underutilized unit, understanding the differences between boom crane truck configurations-capacity, boom type, chassis condition, and compliance history-makes the difference between a smart purchase and an expensive mistake. This guide breaks down every type of boom crane truck on the used market, the features that matter most, and how to choose the right one for your projects and budget.

"Boom crane truck" covers several distinct designs, each optimized for different lifting, transport, and access needs. Mounted boom trucks are affixed to a commercial truck chassis, while unmounted boom trucks are sold without a vehicle or platform-ready to be installed on a chassis the buyer selects. Understanding the main types makes it easier to shortlist the right used units in a marketplace listing or brokerage conversation.
Telescopic boom crane trucks use a straight main boom with multiple hydraulic sections that extend and retract to deliver long vertical and horizontal reach. Telescopic booms extend outward in a predictable, linear geometry, making load charts straightforward and setup relatively fast. These are ideal for steel erection, HVAC positioning, roofing materials, billboard installs, and general construction lifts where heights and working radius are the primary factors.
On the used market, expect capacities ranging from roughly 10 to 65 tons, with boom lengths up to 150 feet on the main boom and total tip heights reaching 200–215 feet when a jib is fitted. Altec telescopic cranes, for example, achieve sheave heights up to 215 feet. Some models feature a maximum main boom length of 151 feet before the jib adds further reach.
For buyers, telescopic boom truck cranes offer simple boom geometry, faster setup, predictable load charts, and a large pool of operators already familiar with their operation. They remain the most common configuration in the mid-to-heavy capacity category and are widely available through platforms like IronMartOnline's boom crane listings.
Knuckle boom trucks have two booms for articulation-a main boom and a secondary hinged section-that fold compactly behind the cab or over the truck bed when not in use. Articulating cranes are designed for maximum payload in tight spaces, and knuckle boom cranes are gaining popularity in the U.S. market for good reason: they can reach around obstacles, work close to the truck, and preserve more payload space on the bed when stowed.
Common applications include building materials delivery, utility work, forestry and log handling, oilfield pipe movements, and urban projects where being highly maneuverable matters more than extreme height. While telescopic booms extend outward, articulating booms fold to navigate obstacles-making knuckle boom trucks the go-to choice in congested areas. Knuckle boom trucks can handle payloads up to 38,185 lbs, placing them firmly in the mid-duty range for construction, maintenance, and utilities.
Used knuckle boom trucks can offer strong value if buyers match crane capacity, outreach, and auxiliary functions-grapples, buckets, winches, and other attachments-to their specific trade. Pay close attention to joint condition, bushing wear, and hydraulic hose routing at each articulation point, as these are the primary maintenance-intensive areas.
Rear-mount units position the crane at the tail end of the chassis, maximizing 360° work area and freeing up bed space for materials or equipment transport. This configuration is ideal for bridge and highway contractors, sign installers, precast concrete crews, and utilities that need full side and rear coverage around the truck.
Rear mounting changes weight distribution significantly, shifting the center of gravity rearward. Buyers evaluating used listings should verify axle ratings, outrigger footprint dimensions, approach and departure angles, and whether the chassis has been properly reinforced. Cab-to-axle (CA) and after-frame length measurements must align with the crane superstructure-mismatches cause stability and road-legality problems that are expensive to correct after purchase.
Service and utility boom trucks pair lower-capacity cranes-typically under 15–20 tons-with integrated service bodies featuring tool compartments, welders, compressors, and storage on Class 5–7 chassis (GVWR roughly 19,500–33,000 lbs). Target users include equipment repair outfits, municipal fleets, line maintenance crews, and small contractors doing daily field service.
Boom trucks integrate multiple functionalities including lifting, material transport, and accessibility, and nowhere is that versatility more apparent than on a well-equipped service truck. On the used market, the overall condition of the service body, PTO, and electrical systems can be as important as the crane itself-a clean crane mounted on a truck with a deteriorated service body and failing auxiliary systems loses much of its practical value.
Some boom crane trucks are designed or approved to carry man baskets or fixed platforms, used for sign work, light pole maintenance, building façade service, and tree care. These units let fleets combine lifting and personnel access duties in one piece of equipment, potentially reducing boom truck rentals of separate bucket trucks.
Regulatory requirements are strict: units must comply with OSHA and ANSI standards for basket rating, guard rails, and overload protection. Documented inspection history is essential on used equipment-safety systems including load-moment indicators, limit switches, and angle indicators must be fully functional. Fleets looking to replace aging bucket trucks should compare these boom truck options carefully, ensuring all platform certifications are current before taking the machine into service.
The attributes below determine whether a used boom crane truck is safe, productive, and good value. Each subsection explains why the attribute matters and what buyers should expect to see in well-prepared listings-detailed specs, clear photos, and inspection notes that remove guesswork.
Rated lifting capacity (in tons) and the manufacturer's load chart govern what the crane truck can safely lift at every combination of radius and boom length. Safety limits depend on boom length, load distance, and load chart specifications-never on headline numbers alone.
The typical lifting capacity of boom trucks ranges from 15 to 65 tons, though smaller units start well below that. Boom trucks can lift capacities from 1,000 pounds to 50 tons depending on configuration. Match capacity to real-world loads: a 4,000 lb HVAC rooftop unit at 60 ft radius requires a very different machine than a 10,000 lb precast panel at 30 ft.
Always review the original manufacturer load chart, confirm it's legible on the unit, and verify that no unauthorized structural modifications-welding, boom section replacements from different models, or uncertified repairs-have been made. These trucks typically have a lower maximum weight capacity than all-terrain cranes, so knowing your actual lift requirements at working radii is critical.
Main boom length and total tip height with a jib determine how far and how high the crane can reach on the jobsite. A 60–90 ft boom handles most light construction and residential work, while 100–150+ ft booms serve commercial and industrial applications. Telescopic boom cranes can reach heights up to 215 feet with jib extensions, and boom trucks can lift loads over 100 feet high-well above a typical 10-story building.
On used units, inspect boom wear points carefully: telescoping section condition, wear pad thickness, slide track alignment, and smoothness of extension and retraction under load. Listings and photos should highlight these areas. For knuckle booms, check each articulation joint for play and hydraulic integrity.
The truck chassis is as critical as the crane. Manufacturer, model year, mileage, GVWR, and axle configuration (6×4, 8×4, tandem, tri-axle) all factor into road legality, stability, and remaining useful life. Boom trucks can travel at highway speeds and typically require no special permits for road use-but only if the chassis, axle ratings, and loaded weight comply with federal bridge laws and state regulations.
Check axle ratings against crane capacity, tire condition, and suspension type. Fleets doing heavy highway miles should prioritize newer, lower-mileage chassis with comfortable cabs, current emissions packages, and reliable automatic transmissions. Mostly on-site units may tolerate higher mileage if the crane structure is strong. A clean crane on a worn-out chassis can trade 15–25% below a comparable unit with a solid truck base.
Outriggers stabilize the boom crane truck during heavy lifts, and their condition directly affects safe operating capacity. Common styles include A-frame, H-style, full-span, and mid-span configurations. Full-span outrigger spreads on mid-duty 25-ton telescopic boom trucks typically measure 5.8–7.2 meters-important dimensions for working in tight spaces or urban streets.
Evaluate outrigger pads, cylinder seals, welds, and controls on used units. Determine whether the manufacturer supports short-jack or asymmetrical setups, which expand flexibility on confined sites. Any electronic stability systems or load-moment indicators (LMI) should be tested and functional. Boom trucks require minimal setup time and space compared to larger cranes, but only when outriggers are in proper working order.
The hydraulic system powers the boom movement and lifting operations-every function from telescoping to slewing to winching depends on clean, responsive hydraulics. Inspect hose age and routing, check for leaks at fittings and cylinders, and test valve responsiveness under moderate load.
Control systems vary: stand-up ground controls, seat-side pedestal cabs, and radio remote systems each suit different operators and applications. Radio remotes offer visibility and flexibility; pedestal cabs provide weather protection during extended operation. Ask for recent hydraulic service records and oil sample results when available, and request videos of all functions operating under load before committing to a purchase.
Model year, engine hours, crane hours (if separately metered), and total mileage work together as indicators of remaining life. High engine hours with low crane hours can signal a chassis that has been heavily road-driven but lightly used for lifting-or a unit that idled extensively. Either way, powertrain wear may exceed what the crane hours suggest.
Documented inspections-annual crane inspections per ASME B30.5, DOT inspections, and maintenance logs-add significant buyer confidence. Listings that call out major rebuilds (new boom sections, cylinder reseals, pump overhauls) with dates and documentation consistently command higher pricing. If you're selling heavy equipment, thorough maintenance records are one of the easiest ways to protect resale value.
CDL class requirements depend on GVWR-most boom crane trucks above 26,001 lbs GVWR require a Class A or B CDL. Bridge law compliance, axle weight distribution, and overall dimensions with outriggers stowed must be verified against state and federal regulations.
OSHA, ANSI, and state-specific regulations govern crane certification and inspection frequency for construction and utility work. Under ASME B30.5, frequent inspections (daily to monthly) and periodic inspections (1–12 month intervals depending on severity of service) are mandatory. Units idle for more than one month require more comprehensive inspection before returning to operation. Verify current certifications and inspection tags before purchase, and budget for bringing lapsed units up to code.
Choosing the right boom crane truck comes down to matching the machine's specifications to your actual work, not just buying the biggest or cheapest unit available. Here's how the key decision factors should guide your search through used listings:
Primary Work Type & Industry - Core applications drive configuration choice. Residential construction and material delivery favor compact knuckle booms. Highway and bridge work demands rear-mount telescopic units with full 360° coverage. Utility line maintenance calls for service-body configurations. Mining and industrial applications may need the heaviest capacities available. Boom trucks are versatile for construction, maintenance, and utilities-but no single setup excels at everything.
Typical Load Weights & Heights - List your heaviest and most frequent lifts with specific weights and heights. Boom truck cranes can lift up to 50 tons and reach over 100 feet, but your loads at your working radii are what matter. A 4,000 lb rooftop unit to 80 ft and a 10,000 lb precast panel to 40 ft require very different machines. Consult load charts at actual working conditions, not just maximum ratings.
Jobsite Access & Terrain - Urban streets, soft ground, or confined industrial sites favor compact knuckle booms with shorter wheelbases and flexible outrigger designs. They are often used in urban areas where maneuverability and compact design are important. Open construction sites with firm, level ground allow full-span outrigger deployment and favor telescopic booms.
Road Miles vs On‑Site Use - Fleets logging heavy highway transportation miles should prioritize newer, lower-mileage chassis with current emissions compliance, comfortable cabs, and reliable drivetrains. Boom trucks can travel at highway speeds, making the road-going chassis a critical daily-use component. Units that mostly operate on-site may tolerate higher mileage if the crane and hydraulics are strong.
Budget & Total Cost of Ownership - Used boom trucks cost between approximately $38,000 and $430,000 depending on capacity, boom length, age, and hours. Balance purchase price against expected remaining life, upcoming major service items (tires, hydraulics, engine emissions), and potential resale value. Brands like Tadano, National Crane, and Elliott tend to retain value better in the mid-capacity used market. Explore financing options to spread costs across the machine's productive life.
Operator Skill & Training - Some crane controls and boom styles have steeper learning curves. Buyers with mixed-experience crews may favor simpler control layouts and widely supported brands where training materials and experienced operators are easy to find. Boom trucks reduce rental needs by combining multiple functions, but only if your team can operate them efficiently and safely.
Resale & Fleet Standardization - Sticking to a few brands and capacities simplifies parts stocking, operator training, and later resale through platforms like IronMartOnline. Integrated hauling capability allows boom trucks to transport and lift in one operation-standardizing around this versatility multiplies fleet efficiency.
Below are answers to the questions contractors and fleet managers most frequently ask when comparing boom crane trucks and browsing used inventory.
A boom crane truck is a truck mounted crane built on a road-legal commercial truck chassis that drives to the job site under its own power, often combining lift and material transport on the same vehicle. Traditional mobile cranes-rough-terrain, all-terrain, or crawler cranes-are purpose-built lifting machines that may require a trailer for transportation and significantly more setup time. Boom crane trucks typically offer faster mobilization and lower operating costs for moderate lifts, while large mobile cranes handle heavier, more complex picks that exceed boom truck capacity.
Capacities on common used models range from under 10 tons to 65+ tons, and boom trucks can lift up to 50 tons or more on larger units. However, actual allowable loads depend on boom length, working radius, and outrigger setup-a 50-ton-rated truck may only be allowed to lift 8,000 lbs at full boom extension. Always consult the specific unit's load chart in the listing and never exceed manufacturer ratings.
Purchasing used makes sense when you have frequent weekly use, predictable long-term projects, or when boom truck rentals are scarce or expensive in your region. Boom trucks reduce rental needs by combining multiple functions-lifting, hauling, and sometimes personnel access-into one piece of equipment. Renting may still be smarter for rare specialized lifts, short-term demand spikes, or when testing a new crane type before committing capital. IronMartOnline can help owners sell under-utilized units later, improving the economics of buying used.
