China truck crane OEM and export listings concentrate in Shandong (Jining) and Shanghai, with the Wolwa Group facility covering 88,000 m² and reporting 1,000+ employees and annual sales of USD 10-30 million [S3]. Made-in-China's index surfaces the full XCMG-style QY model band — QY12, QY16C, QY16D, QY25, QY25K, QY25K5, QY30K5, QY35K5, QY40K, QY50B, QY50K — as the dominant 12-50 ton class exported from Chinese ports [S2].
Small-class 6-ton mobile cranes list at USD 20,000-50,000 per unit FOB Shanghai with 1-unit minimum order quantity and 15 units per month supply capability under TT or LC payment terms [S6]. A representative 20-ton class unit (model QY20G.5) carries overall dimensions of 12,400 mm L × 2,500 mm W × 3,320 mm H, with 26,020 kg travel weight split 6,900 kg front axle / 19,120 kg rear axle — a useful envelope benchmark when pre-checking bridge formulas and transport permits [S8].
Model-Code Band and Tonnage Class Map
Chinese truck crane model codes follow the "QY" prefix convention (Qingyu / crane-yidong), where the trailing two digits express nominal tonnage: QY12 = 12 ton, QY25K5 = 25 ton fifth generation, QY50K = 50 ton [S2]. The QY25K5 and QY30K5 sit in the 25-30 ton sweet spot, while QY40K and QY50K cover the 40-50 ton segment [S2]. Below the QY band, Okorder lists a generic 16-ton construction truck crane platform using HQ600 high-strength steel for the upper structure, with free factory-based operator training included in the supply scope [S4].
The 6-ton entry-level tier, priced USD 20,000-50,000 FOB Shanghai, is positioned for site work, station loading, sea port and warehouse duty rather than heavy infrastructure lifts [S6]. A direct counterpart article on construction equipment sourcing notes that 1-unit MOQ with 15-unit monthly capacity is a typical small-class benchmark — the same pattern seen in the pneumatic-system OEM tier map, where 1-unit MOQ and 15-unit run-rates are common at entry tier [S6]. Buyers comparing this to the tapered-roller-bearing selection guide will recognize that envelope checks (axle load split, travel height under 3.4 m) matter more than headline capacity for road-transport compliance [S8].
Steel, Axle Distribution and Structural Anchors
Upper-structure steel grade HQ600 is a stated 600 MPa-class high-strength plate used on at least one 16-ton construction truck crane supplier's boom assembly, paired with "top brand components" for hydraulics, slewing bearings and winch motors [S4]. The 20-ton QY20G.5 ships at 26,020 kg total travel weight with a rear-biased axle split — 6,900 kg front / 19,120 kg rear, i.e. ~73.5% on the drive bogie — which is typical of crane-carrier layouts where the upper counterweight hangs behind the rear axle [S8].
Travel envelope (L 12,400 mm × W 2,500 mm × H 3,320 mm) keeps the unit inside most 40-foot container and flat-rack limits when the boom is stowed, a key spec for Africa and Middle East export lanes that containerise equipment for Red Sea and West Africa roll-on/roll-off [S8]. The 6-ton class smaller envelope is broadly half of that footprint, which lines up with its USD 20,000-50,000 price band and 15-unit monthly throughput [S6].
Supplier Cluster Geography: Shandong, Shanghai, Jiangsu
Wolwa Group Co., Ltd. is a Jining City, Shandong-based manufacturer founded in 2005 covering 88,000 m², with 1,000+ employees and USD 10-30 million annual sales; the company lists excavators as its main product line but markets truck cranes in adjacent categories [S3]. Beijing Zhongpu Construction Machinery operates a Shanghai office at Room 411, Litong Business Building, No. 349 Jiudu Road, Songjiang District, Shanghai — a typical trading-company front used by Shandong-origin OEMs to handle export documentation [S1]. Shanghai Super-Above Industry Holdings sits in the same export-trading cluster, with stated main markets in Eastern Europe, Southeast Asia, Africa and the Middle East under FOB, CFR and CIF Incoterms [S5].
The cluster is not unlike the SPC flooring cluster map 2026, where Shandong and Jiangsu provinces concentrate base production while Shanghai handles export documentation. Buyers who have worked through the hot-chamber die casting machine supplier map will see the same exporter-anchored sourcing structure: factory in inland province, trading arm on the coast.
Pricing Bands, MOQ and Incoterm Anchors
The 6-ton class mobile crane reference price is USD 20,000-50,000 per unit, with 1-unit MOQ, 15-unit monthly supply capability, and TT or LC payment terms; FOB Shanghai is the listed loading port [S6]. Higher-tonnage QY25K5 / QY30K5 units sit in a different band that requires direct quotation — Made-in-China's QY25K search page does not surface a single sticker price, only a multi-supplier index, indicating that 25-ton+ truck cranes are quote-on-inquiry rather than catalogue-priced [S2]. The 16-ton construction truck crane on Okorder follows the same quote-on-inquiry pattern with free factory training bundled in [S4].
Shanghai Super-Above publicly declares FOB, CFR and CIF as standard Incoterms — the same three-mode set that Wolwa and Beijing Zhongpu offer through Made-in-China listings [S5]. For a related cross-reference on container-load economics, the asphalt paver suppliers 2026 sourcing note shows that FOB/CFR/CIF is the default three-mode set across Chinese construction-equipment exporters, not just crane vendors.
Tyre, Component and Aftermarket Spec Layer
Truck crane tyres are a distinct procurement line, with the Made-in-China 2026 tyre-price index calling out GCC-certified OTR radial loader patterns such as the Hanmix RR-312 E2 [S7]. The "GCC certified" tag is material for Middle East and Africa buyers who must present Gulf-region conformity paperwork at port of entry, and the tyre spec is separate from the crane OEM's own warranty — buyers must align load index, E2 pattern and rim diameter against the carrier axle rating rather than accept the OEM's standard fitment [S7].
Boom and slewing-system components (hydraulic cylinders, slewing bearings, winches, outrigger pads) are not enumerated by Wolwa or Super-Above in their public Made-in-China profiles; Okorder's 16-ton listing refers generically to "top brand components" without naming the supplier, which is the standard hedging language in Chinese construction-machinery export listings [S4]. Buyers specifying 25-ton+ units should request a component list — slewing-bearing maker, hydraulic pump model, main valve brand — as part of any technical proposal, since the same OEM may use different sub-suppliers for the 6-ton vs 50-ton bands.
Selection Criteria: Tonnage, Steel, Aftermarket, Export Lane
A spec-driven shortlist for a 2026 truck crane procurement should fix four decision axes: (1) tonnage class, (2) upper-structure steel grade and documented heat-treatment, (3) axle-load envelope for the destination country's road permits, and (4) tyre / component after-market availability in the destination port. On axis (1), the QY12-QY50K range covers virtually all general-construction duty [S2]. On axis (2), HQ600 plate is a stated spec on at least one 16-ton listing; buyers in the 25-50 ton band should request the same declaration in writing [S4]. On axis (3), the QY20G.5's 26,020 kg / 73.5% rear-axle split is a useful benchmark — anything heavier than ~32 t GVW will require multi-axle trailer rather than self-drive transport in most African and Middle Eastern jurisdictions [S8]. On axis (4), GCC-certified OTR tyres are a checkable spec on the 2026 sourcing index [S7].
Buyers who need to cross-check lifting-class envelopes against carrier specifications can lean on the truck-mounted-crane reference page for the carrier-crane mechanical interface, and use the aerial-work-truck reference to separate boom-lift aerial platforms from true truck cranes when RFQs get conflated. The concrete-mixer-truck reference is a useful control comparison for axle-split budgeting where the carrier shares the same 6×4 / 6×2 layout.
Limitations and Watch-Outs in the 2026 Sourcing Cycle
Public Made-in-China and Okorder listings do not state emission tier (Euro III / Euro V / Stage V / EPA Tier 4 Final) for the carrier diesel engine — a critical gap for European Union and North America-bound shipments, since post-2024 EU non-road mobile machinery rules are tightening [S1][S4]. Wolwa's USD 10-30 million annual-sales figure is a self-declared range, not an audited number, and "1,000+ employees" without a fixed headcount is common hedging on Chinese trading-company pages [S3]. The 15-unit monthly supply capability on the 6-ton class is fine for 1-2 unit pilot orders but will not cover a 30-unit fleet delivery in a single month — buyers planning fleet deployment should request a 3-month rolling production slot [S6].
Trackable signals to watch through 2026 H2: (1) Made-in-China QY25K and QY50K pages moving from multi-supplier index to per-listing sticker prices, which would indicate 25-50 ton segment commoditisation; (2) emergence of explicit Euro V / Stage V engine model codes on Okorder 16-ton listings, which would unlock EU-bound export lanes [S4]; (3) component-level disclosure (slewing bearing maker, hydraulic pump model) on Wolwa and Super-Above product pages, which would let buyers run a bill-of-materials side-by-side against XCMG and SANY directly [S3][S5].
