Truck-mounted aerial work platforms (also called aerial work trucks) span 5 m single-mast one-man lifts to 90 m telescopic booms on 48 t chassis, with the working envelope dictated by boom geometry and chassis rating rather than by a single "standard" model [S2]. The class is not one product: it is a family whose selection criteria are working height, lateral outreach, basket capacity, terrain, and whether the unit must drive on public roads under a normal truck license [S2][S3].
Inside that family, the dominant sub-types used in 2026 specifications are telescopic booms, articulated booms, vertical mast lifts, scissor platforms, trailer-mounted units, and truck-mounted self-propelled lifts, each mapped to a different working-height and load band [S2][S3]. The aerial work platform reference page covers the MEWP-side terminology that overlaps with these chassis-mounted variants.
Boom Geometry: Telescopic vs Articulated vs Mast vs Scissor
Telescopic booms on truck-mounted chassis deliver the largest envelopes, with PALFINGER's >3.5 t class reaching 30–90 m working height and 20–41 m lateral reach via a distinctive X-Jib [S2]. The <3.5 t telescopic class covers 17–28 m working height on a lighter chassis, with an optional battery pack for hybrid operation [S2]. Articulated booms, with single or double outrigger articulation, trade straight-line reach for up-and-over access around obstacles; the new PALFINGER TEC range combines increased reach, improved basket stability, higher basket load, and reduced weight at 19–28 m in the 3.5 t chassis class [S2].
At the lower envelope, vertical mast lifts, one-man lifts, and aerial order pickers from Chinese OEM Hangzhou Sivge (SIVGE, founded 1995) cover 8–12 m platforms using aluminum-alloy masts, with basket capacities around 300 kg and 24 V battery drive for indoor or finished-floor work [S3]. The truck-mounted lift, scissor working platform, and trailer-mounted lift categories on the same SIVGE catalogue sit one step higher in working height, with self-propelled electric articulated booms reaching 16 m on wheeled chassis for warehouse and facility maintenance [S3]. For readers cross-referencing the dump truck page, the difference is functional: a aerial work truck carries a man-riding platform and stability logic, not a tipping body.
Chassis-Class Map: <3.5 t, 3.5 t Standard, and Heavy 12–48 t
Chassis rating is the second classification axis. PALFINGER's published portfolio is split into <3.5 t, the 3.5 t class (TEC range), and >3.5 t, with overall truck-mounted platform compatibility stated for chassis from 3.5 t up to 48 t metric tons [S2]. Below 3.5 t, the chassis is typically a light commercial vehicle (van or pickup-derived) and the platform is usually a compact telescopic or vertical mast, with maximum working heights of 17–28 m and a 3.5 t dead weight tuned for road-legal operation [S2]. The 3.5 t class is where hybrid battery packs, full-color digital control panels, and memory-function one-button positioning start to appear as standard features on the TEC range [S2].
Above 3.5 t, the structure changes. Special-profile sections and lightweight materials bring dead weight down so the truck can carry more tools and materials to height, and the X-Jib geometry takes over for 30–90 m working height with 20–41 m lateral reach [S2]. Heavy chassis 12 t and above are required for any boom above roughly 45 m, because outrigger pad load, rotational moment from the turret, and counterweight sizing all scale with outreach. The reach truck page is a useful contrast: a reach truck is rated for warehouse-aisle racking, while a truck-mounted reach-class boom is rated for roadside or off-road deployment with a man-riding basket.
Working-Height and Outreach Bands: A Side-by-Side Comparison
The cleanest way to compare sub-types is on four decision criteria: working height, lateral reach, basket load, and road-legal chassis weight. PALFINGER's published numbers give the bands: telescopic <3.5 t at 17–28 m, TEC range 19–28 m on 3.5 t, telescopic >3.5 t at 30–90 m with 20–41 m lateral reach, articulated platforms across the same chassis range, and kits/special solutions for 11–24 m niche tasks such as tunnel, water, or rough-terrain work [S2]. On the lower end, SIVGE's catalog of vertical mast lifts, single-mast lifts, one-man lifts, and scissor working platforms sits at roughly 8–16 m with 300 kg-class basket load, optimized for indoor or smooth-surface work rather than road deployment [S3].
The trade-off matrix is direct: telescopic booms win on straight-line reach and height, articulated booms win on up-and-over obstacle clearance, vertical masts and one-man lifts win on footprint and indoor floor loading, and scissor platforms win on vertical-only large-platform area for two-person loads [S2][S3]. For very low working heights (5–8 m) in finished-floor or retail environments, a 24 V battery-driven 10 m platform with 300 kg capacity is the typical spec [S3].
Drive and Energy: Diesel, Battery, Hybrid
Drive power is the third axis. The <3.5 t and 3.5 t PALFINGER telescopic classes are offered with an optional battery pack for hybrid operation, paired with the digital control panel and memory function on the TEC range [S2]. Heavy >3.5 t telescopic platforms are typically diesel-hydraulic with the truck PTO supplying hydraulic flow, which is why the 30–90 m class still favours a 12 t+ chassis rather than a battery-electric one. SIVGE's indoor and warehouse-class equipment, by contrast, is consistently 24 V battery drive with self-propelled electric articulation, including 16 m self-propelled articulated boom lifts and 8 m single-mast lifts, all using aluminum-alloy structures to keep the dead weight inside warehouse floor-loading limits [S3].
Selection here is straight engineering: choose battery or hybrid when indoor air quality, noise, or exhaust rules apply, and choose diesel-hydraulic when the job site is outdoor, off-grid, or above roughly 30 m working height where the hydraulic power density still beats batteries. For a related energy-and-power sizing discussion, the harmonic reducer market sizing piece covers the rotary-actuation side of the same engineering envelope that drives boom slew and basket leveling.
Use-Case Routing: Telecom, Construction, Utilities, Indoor Maintenance
Roughly 60% of truck-mounted telescopic platform sales in the published PALFINGER portfolio target telecom, sign, and street-lighting work in the 17–28 m band, with 30 m and above reserved for wind-energy blade maintenance, high-rise facade work, and special-solution tunnel or water deployments [S2]. The 11–24 m "Kit" band is for utilities and small-fleet operators who need a versatile boom that can be re-mounted on multiple chassis, and the special-solutions line covers stationary, rough-terrain, water, and tunnel installations [S2]. On the lower end, SIVGE's one-man lifts, vertical masts, and order pickers are specified for warehouse inventory, retail fit-out, and facility-maintenance contracts where the platform has to enter a public building and run on finished floors [S3].
Articulated booms are the default for utility line work and tree-care because the knuckle boom can reach over a fence, a parked car, or a hedge to position the basket, while a straight telescopic cannot [S2]. For very large platform areas (two-person tools and materials), scissor working platforms in the SIVGE catalogue are specified with larger baskets and higher load ratings than mast or one-man lifts, but at the cost of reach [S3]. The cross-link to concrete mixer truck installation and site-prep is operational, not technical: both require paved access and outrigger pad preparation before deployment, as covered in the concrete batching plant installation guide.
Standards, Stability Logic, and Subframe Engineering
The mechanical backbone of every truck-mounted platform is the subframe: double longerons, front and rear fixed legs, a rotary table bearing, the rotary table, and reinforcing ribs, with the front edge typically shaped as a triangular, U-, or L-section to avoid a stiffness step against the host chassis [S1]. Case-based-reasoning (CBR) CAD research on subframe design shows that the subframe is the part that gets redesigned for almost every new chassis, because the chassis frame width, height, and mounting-hole pattern differ between truck models even when the boom above is identical [S1].
Stability is governed by outrigger pad load and the moment reaction at each pad, which is why the >3.5 t class is paired with the heavier chassis and counterweight [S2]. Operators control outrigger deployment and boom motion from a full-color digital control panel in the basket, and the memory function stores preferred working positions for one-button recall [S2]. Buyers evaluating used truck-mounted platforms should weigh the chassis-year, subframe retrofit history, and the most recent outrigger-pad load test alongside the boom-hour meter, because subframe cracks are the typical failure mode rather than boom-fatigue [S1][S2].
