As of May 2026, DirectIndustry's industrial-manufacturer index for truck-mounted concrete pumps lists 16 industrial-grade models from five named clusters — Putzmeister (1), SANY (9), SCHWING GmbH (2), XCMG (2) and Henan YCZG Machinery Manufacture Co. (2) — alongside 7 mobile variants [S1].
Okorder SKU pages dated between April 2026 and May 2026 confirm live supply for short-, mid- and long-reach units: HB24A 24 m boom, HB37A 37 m boom (150 m³/h rated productivity), and the LP90.18.195DU long-reach, all advertised at 1,500 PCS/month supply capability out of Shanghai [S3][S5][S7].
Five-OEM Cluster Map and Active Model Count
The supplier map compresses into five named OEMs plus a long tail of Chinese trading-channel SKUs. DirectIndustry's filter set returns 16 industrial-grade models filtered by "industrial" attribute, broken down as SANY 9, SCHWING 2, XCMG 2, Henan YCZG 2 and Putzmeister 1 [S1]. Okorder's parallel channel carries additional non-branded HBCS-series and "diesel-engine generator" variants listed at 1,000 kg verified-weight SKUs [S2][S6].
China-origin supply dominates the verified-listing count: Shanghai is the primary declared loading port across Okorder SKUs (HB24A, HB37A, LP90.18.195DU), with "China Main Port" and Tianjin cited for Putzmeister pipe and generator-set variants [S3][S5][S6][S8]. Standard certifications appearing on datasheets are ISO 9001:2000 and ISO BV certificate; warranty is uniformly 6 months across the HBCS, HB24A, HB37A and LP90.18.195DU listings [S2][S3][S5][S6][S7].
Spec Bands: Output, Pressure, Boom Reach, Chassis
Verified spec windows cluster into three reach bands. Short-reach: HB24A at 24 m vertical boom, crawler-excavator-derived hydraulic transmission [S3]. Mid-reach: HB37A at 37 m with wet-mix shotcrete type, rotor-type structure, rated productivity 150 m³/h, hydraulic drive, ISO 9001:2000 [S7]. Long-reach: LP90.18.195DU, Deutz diesel engine, orange livery, hydraulic-machined concrete-pump type, ISO 9001:2000, global export markets [S5].
Chassis and engine data are partial on the trading-channel pages but converge on diesel power, hydraulic-machined S-valve distribution, and 600 L fuel-tank capacity on the generator-series SKU. Engine power on the HBCS series is declared at 176 kW, with operating weight 11,650 kg and envelope dimensions 9,080 × 2,490 × 3,150 mm (L × W × H) [S2][S6]. The 37 m HB37A unit feeds 150 m³/h at the rated 1,480 r/min engine speed defined on the parallel generator-pump listing [S6][S7]. For buyers cross-referencing carrier-truck options, our concrete pump truck sizing guide maps boom-reach bands to chassis-axle count. The encyclopedia entry on the truck-mounted concrete pump covers the canonical definition and kinematic envelope.
Selection Criteria: Output vs Pressure vs Reach
Three decision criteria dominate OEM selection — theoretical output (m³/h), concrete pressure (bar), and vertical boom reach (m). DirectIndustry exposes all three as filterable ranges: output max. m³/h, pumping pressure max. bar, plus min/max length and height filters in cm [S1]. Okorder SKU data confirms the practical floor: HB24A anchors the short-boom segment, HB37A anchors the mid-reach 150 m³/h productivity tier, and LP90.18.195DU anchors the long-reach segment [S3][S5][S7].
Buyers comparing 24 m vs 37 m vs long-reach units should weight the job-site vertical-reach requirement first, then the m³/h output target, and only then the pumping-pressure bar rating. The 24 m HB24A suits low-rise residential decks; the 37 m HB37A (150 m³/h) suits mid-rise commercial pours; the LP90.18.195DU suits high-rise and infrastructure where Deutz diesel prime-power and long boom kinematics are required [S3][S5][S7]. Standard protocol across the verified listings is ISO 9001:2000 quality-system plus ISO BV certificate for export-declared SKUs [S2][S3][S5][S6][S7].
Who the Five OEMs Are For — and Who They Are Not
SANY's 9-model count and SCHWING's 2-model count make them the default picks for buyers who need multi-tier reach coverage from a single OEM line [S1]. XCMG and YCZG suit price-sensitive emerging-market pours where the 6-month Okorder warranty and 1,500 PCS/month declared capacity are acceptable [S1][S2][S5]. Putzmeister's single tracked model — confirmed via a separate Putzmeister-branded pipe SKU at 50 pc MOQ and 2,000 pc/month supply capability out of Tianjin — suits buyers who specifically need Putzmeister wear-parts continuity on a fleet already on Putzmeister hydraulics [S1][S8].
These five OEMs are not interchangeable. Buyers needing 50+ m vertical reach, factory-direct service-network coverage in Europe or North America, or emission-certification documentation beyond ISO 9001:2000 will find the trading-channel SKUs underspecified and should engage Putzmeister, SCHWING or SANY direct rather than the Okorder B2B layer. Buyers needing small-lot (under 5 units) prototyping, on the other hand, get faster RFQ turnaround on the Okorder channel where Min Order Qty is 1 PCS across HB24A, HB37A and LP90.18.195DU [S3][S5][S7].
Comparison Table: Top OEMs Against Four Buying Criteria
Filtering the DirectIndustry and Okorder datasets against four decision criteria yields a tight spec matrix. Verified-listings count: SANY 9, SCHWING 2, XCMG 2, YCZG 2, Putzmeister 1 [S1]. Standard certification disclosed: ISO 9001:2000 across HB24A, HB37A, LP90.18.195DU and the HBCS series; ISO BV certificate on HBCS [S2][S3][S5][S6][S7]. Supply capability declared: 1,500 PCS/month on HB24A, HB37A, LP90.18.195DU; 2,000 pc/month on Putzmeister pipe [S3][S5][S7][S8]. Warranty term: 6 months uniformly across the HBCS, HB24A, HB37A and LP90.18.195DU listings [S2][S3][S5][S6][S7].
Buyers who already operate a concrete mixer truck fleet should confirm the pump chassis shares the same OEM service network before committing. Where the pour is a one-off or short-program job, the truck-mounted concrete pump sizing breakdown provides a cross-reference of output, pressure and reach bands to target model codes.
Limitations and Failure Modes Buyers Should Track
Trading-channel data is partial. The HB24A datasheet labels its driveline as "Crawler Excavator / Internal Combustion" with hydraulic transmission — a category mismatch that signals the listing is repurposed from an excavator template, so buyers must request a corrected driveline spec sheet before PO [S3]. The 150 m³/h productivity figure on the HB37A is a nominal rating, not a sustained-duty figure; sustained duty on rotor-type wet-mix units typically runs below nominal [S7].
Supply capability is declared, not audited. The 1,500 PCS/month figure on three different Okorder SKUs (HB24A, HB37A, LP90.18.195DU) is a self-reported maximum, not a verified run-rate, and lead-times swing with raw-steel and Deutz engine allocations [S3][S5][S7]. The 6-month warranty term across all four verified SKUs is shorter than the 12-month typical for direct-OEM channels — a signal that the trading-channel price reflects a service-net deficit, not just a margin cut [S2][S3][S5][S6][S7]. Buyers needing full emission documentation for European or North American deployment should request the Stage V / EPA Tier 4 Final paperwork up front, since neither ISO 9001:2000 nor ISO BV certificate covers in-service emissions compliance.
Sourcing Standards and Procurement Channels
Two standards dominate the verified datasheets: ISO 9001:2000 quality-system (declared on HB24A, HB37A, LP90.18.195DU and HBCS-series variants) and ISO BV certificate (declared on the HBCS-series and diesel-generator variants) [S2][S3][S5][S6][S7]. Payment terms across the channel are uniformly TT or LC; loading ports cluster on Shanghai, with "China Main Port" and Tianjin as secondary declarations [S3][S5][S6][S8].
For a broader concrete pump truck supplier map covering boom reach and sourcing levers, the parallel guide consolidates OEM counts against FOB price signals. Buyers comparing truck-mounted concrete pumps against trailer-mounted or dump truck alternatives for low-output pours can also reference our dump truck spec guide for pulp and paper mill service to see where the carrier-truck class overlaps with concrete-pump carrier chassis.
Two signals to track over the next two quarters: any change in the 1,500 PCS/month self-reported supply-capability figure on the HB24A, HB37A and LP90.18.195DU listings (a leading indicator of OEM allocation shifts), and any update to the 6-month Okorder warranty term (a lagging indicator of post-sales-service maturity on the trading channel) [S3][S5][S7].
