Cement Tanker Trailer · Published: July 24, 2026 · Updated: July 24, 2026 · By Kales Vehicle Technical and Central Asia Business Teams · Technical review scope: tank, pneumatic discharge, chassis configuration, and export documentation · Market focus: Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, and Russian-speaking CIS procurement
Kales 35m³ bulk cement tanker trailer: a 12,500 mm, three-axle pneumatic powder semi-trailer developed for long-distance cement logistics in Central Asia and Russian-speaking markets. In regional procurement searches, this vehicle is commonly called a Полуприцеп-цементовоз, цементовоз полуприцеп, or cement tank semi-trailer.
The configuration combines a Q355 high-strength steel tank, approximately 34m³ effective volume, an independent diesel-driven 12m³/min compressor, and selectable cold-weather braking components. Final material grade, homologation package, axle loading, and winter equipment are confirmed in the signed technical agreement for the destination country.
Quick answer: this 35m³ cement bulker is best for CIS fleets that need about 33 tonnes of reference payload, independent unloading at remote projects, and a long 12,500 mm platform for controlled axle-load distribution on cross-border highways. For operation approaching -40°C, specify the required low-temperature steel impact grade, material certificates, low-temperature lubricants and seals, an air dryer, and WABCO-compatible anti-freezing brake controls in the purchase agreement. Kales can prepare the technical drawings, VIN data, conformity documents, and border-delivery file used by the buyer’s accredited EAEU certification body and customs broker.

Where This CIS Cement Bulker Fits
The 35m³ Kales cement tanker is intended for cement producers, dry-bulk carriers, batching-plant supply fleets, and infrastructure contractors operating between plants, border terminals, depots, and remote construction sites. It is configured for Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan, and comparable Russian-speaking procurement programs, subject to each country’s registration and mass limits.
Best for
- Long-distance cement and fly-ash routes across open steppe and cross-border highways
- Remote sites without a dependable stationary air source
- Fleets standardised around Weichai, FUWA, BPW, SAF, JOST, or WABCO service networks
- Buyers who need a documented EAEU homologation support package and overland border delivery
- Operations that need a 35m³ platform rather than a larger-volume multi-compartment tanker
Not ideal for
- Operation at -40°C unless the complete low-temperature material and component package is written into the technical agreement
- Any route where the 4,000 mm reference height, 40,000 kg mass, or selected axle loads exceed national limits
- Wet cargo, liquid products, food-grade cargo, or powders whose density and fluidisation characteristics have not been reviewed
- Sites without a compatible receiving silo, safe pressure procedure, and trained unloading personnel
Core Advantages for CIS and Central Asian Fleets
| Procurement priority | Technical direction | Operational value |
|---|---|---|
| Cold-climate preparation | Specified low-temperature Q355 grade, certified impact properties, WABCO-compatible anti-freezing valve, air dryer, low-temperature seals and lubricants | Reduces brittle-fracture, condensate icing, and frozen-control risk when the complete package is correctly selected and maintained. |
| Long-route stability | 12,500 mm overall platform with selectable 4,300-4,600 mm front wheelbase and engineered axle-load distribution | Supports predictable tracking and load distribution on high-speed cross-border routes. Stability still depends on tank geometry, suspension, tyres, speed, wind, and loading practice. |
| Low-residue unloading | Large-area fluidisation bed (Аэрационная система), 1.2-1.8 t/min reference rate, and ≤0.3% residual target | Reduces unloading time and retained product when cement condition, pressure, hose arrangement, and operator procedure meet the design basis. |
| Independent power station | Huafeng 4105 or Weichai diesel engine with 12m³/min twin-cylinder compressor | Allows pneumatic unloading at remote infrastructure sites without relying on plant electricity or a stationary compressor. |
| Tractor compatibility | 50 mm (2 inch) or 90 mm (3.5 inch) king pin | Supports specification matching for Shacman, Sitrak, HOWO, KAMAZ, MAZ, and other tractors after fifth-wheel height and load checks. |
| Homologation support | Technical drawings, VIN data, conformity documents, component details, and liaison with the buyer’s broker/certification body | Provides the evidence needed for the applicable EAEU TR CU 018/2011, ОТТС, and ЭПТС process without claiming automatic approval. |
Specification-Backed Advantages
- Tank structure: the reference 5 mm Q355 shell and 6 mm end plates establish a defined material baseline; the required low-temperature impact grade is confirmed against the minimum design temperature.
- Pneumatic output: a 12m³/min twin-cylinder compressor supports independent unloading, with reference output of 1.2-1.8 tonnes/min under suitable operating conditions.
- Load planning: three curb-weight and wheelbase directions let the engineering team reconcile payload, axle-group load, tractor fifth-wheel load, and destination-country limits before production.
How the Tank and Pneumatic Unloading System Work
The Kales 35m³ cement tanker uses a pressure tank, internal fluidisation bed, intake piping, safety controls, discharge piping, and an onboard compressor. Compressed air passes through the fluidisation material and suspends the cement particles so pressure can move the powder towards the outlet. The related bulk powder tanker operation and maintenance guide explains loading, pressure control, discharge, depressurisation, cleaning, and inspection in more detail.
The stated 1.2-1.8 tonnes/min discharge rate and ≤0.3% residual are engineering reference values, not unconditional guarantees. Cement moisture, particle size, ambient temperature, air-slide condition, hose length and lift, system pressure, receiving-silo back pressure, and operator sequence all affect actual performance.
Tank-section options
| Dimension | Scheme 1 | Scheme 2 |
|---|---|---|
| Tank length including end plates | 8,200 mm | 8,080 mm |
| Maximum tank width | 2,500 mm | 2,550 mm |
| Maximum cross-section height | 3,050 mm | 3,170 mm |
| Buyer selection basis | Narrower envelope and route-clearance preference | Wider section where national width and registration rules permit |
Kales confirms tank section, overall height, axle layout, and tractor coupling geometry together. A longer 12,500 mm platform can improve longitudinal load distribution and directional tracking, but length alone does not lower the centre of gravity; rollover resistance also depends on tank cross-section, loaded centre height, suspension, tyre behaviour, speed, steering input, and crosswind.
Cold-Climate Configuration for Operation Down to -40°C
A trailer should only be described as suitable for -40°C after the minimum design temperature is tied to verified material and component data. For the tank and structural parts, the technical agreement should identify the exact Q355 grade, low-temperature impact requirement, heat numbers, and mill certificates. Welding procedures, consumables, and inspection records must match that material selection.
- Air system: WABCO-compatible air dryer, oil-water separator, anti-freezing emergency relay valve, protected drain points, and a maintenance interval based on condensate load.
- Power unit: low-temperature starter, suitable battery capacity, winter-grade diesel and lubricants, fuel filtration, and optional pre-heater according to the agreed temperature range.
- Seals and hoses: elastomers and pneumatic hoses selected for the declared minimum temperature rather than standard temperate-climate parts.
- Operating control: daily condensate draining, dryer-cartridge service, pressure-leak inspection, and warm-up procedures documented for the fleet.
Power Station and No-Compressor Option
The standard independent unloading package combines a Huafeng 4105 or Weichai diesel engine with a 12m³/min Suzhou or Fuda twin-cylinder compressor. Weichai is widely used across Central Asian heavy-vehicle fleets, which can simplify access to routine filters and service knowledge; the buyer should still verify the exact model’s local parts coverage.
If every receiving site has a verified stationary air source, Kales can quote a no-compressor configuration. Removing the front power package can shorten the trailer to approximately 8,400 mm and reduce curb weight, but the external source’s pressure, flow, air quality, coupling, hose route, and operating responsibility must be approved before the order is frozen.
Braking, Suspension, Axles, and Tyres
| System | Available configuration | CIS buyer check |
|---|---|---|
| Braking | Aluminium air tanks, dual brake chambers, emergency relay valve, Ruili/Kormee ABS; WABCO ABS/EBS and air dryer upgrade | Confirm cold-temperature rating, EAEU documentation, diagnostics access, and local service support. |
| Axles | FUWA, Kales, BPW, or SAF; front lift axle optional | Match legal axle loads, empty-running strategy, bearing/brake parts availability, and workshop capability. |
| Suspension | Mechanical leaf spring or air suspension | Mechanical suspension favours rugged sites and simple repair; air suspension favours highway ride and weld-load protection. Compare both in the leaf spring vs air suspension guide. |
| Landing gear | FUWA, Kales, or JOST | Confirm parked load, shoe type, low-temperature grease, and fleet standardisation. See the semi-trailer landing gear selection guide. |
| Tyres | Dual tyres or super singles with route-matched size and load index | Review cold inflation pressure, casing supply, spare strategy, rolling resistance, and legal rating using the semi-trailer tyre and wheel guide. |
| King pin | 50 mm or 90 mm | Confirm fifth-wheel size, coupling height, imposed load, and tractor compatibility; compare the Kales 50 mm and 90 mm king pin options. |
EAEU, ОТТС, and ЭПТС Documentation Scope
For an EAEU-market vehicle, the applicable approval path should be confirmed before production with the buyer’s accredited certification body and customs broker. Kales can design the agreed configuration with reference to applicable requirements of TR CU 018/2011 and provide factory conformity documents, technical specifications, drawings, component information, and VIN data for the ОТТС and ЭПТС workflow.
ОТТС issuance is controlled by the authorised conformity-assessment process, not by the manufacturer alone. The importing party remains responsible for confirming national registration, customs, recycling-fee, dimensional, mass, lighting, braking, and electronic-passport requirements. The signed technical agreement and pro forma invoice should list every certification-sensitive component before production starts.
DAP Border-Port and TIR Delivery
- Configuration review: buyer provides cargo density, route, minimum temperature, tractor model, target payload, unloading-site data, destination, and preferred axle/brake brands.
- Technical and document freeze: both parties confirm dimensions, mass, components, low-temperature package, drawings, commercial terms, and certification responsibilities.
- Production and inspection: Kales supplies agreed production records, dimensional checks, tank/pneumatic inspection evidence, and vehicle identification documents.
- Border delivery: the quotation can be prepared for DAP Khorgos, Alashankou, Bakhtu, or Kashgar, with handover scope and customs responsibility stated under the selected Incoterms rule.
- Inland option: TIR road transport to destinations such as Almaty or Tashkent can be arranged subject to carrier availability, route permits, dimensions, and the final delivery agreement.

Frequently Asked Questions
What is a Полуприцеп-цементовоз?
A Полуприцеп-цементовоз is a semi-trailer designed to carry dry bulk cement in a sealed pressure tank and unload it pneumatically into a receiving silo. The Kales CIS model has 35m³ total volume, approximately 34m³ effective volume, three axles, and an optional independent diesel-compressor package.
Is the Kales 35m³ cement tanker certified for -40°C?
Cold-weather suitability is configuration-specific, not automatic. For a declared -40°C design target, the order must specify the exact low-temperature steel impact grade, mill certificates, welding requirements, seals, hoses, lubricants, battery and starting package, air dryer, and brake-valve ratings. Kales confirms these items in the technical agreement before production.
Why use the 12,500 mm extended platform?
The 12,500 mm layout provides room for the power station and supports engineered distribution between the king pin and 24,000 kg reference tri-axle group. The longer layout can improve tracking and longitudinal load distribution, but it does not lower the centre of gravity by itself; tank geometry, suspension, tyres, load condition, speed, and crosswind remain critical.
How fast does the trailer unload cement?
The reference discharge rate is approximately 1.2-1.8 tonnes per minute, with a target residual of ≤0.3% under suitable conditions. Actual results depend on cement moisture and particle condition, fluidisation-bed cleanliness, compressor output, hose length and lift, pressure, receiving-silo back pressure, ambient temperature, and operator procedure.
Can the trailer unload without an external air source?
Yes. The standard direction uses a Huafeng 4105 or Weichai diesel engine and a 12m³/min Suzhou or Fuda twin-cylinder compressor. A no-compressor version is available when the buyer verifies a compatible stationary source at every unloading location.
Can Kales provide documents for ОТТС and ЭПТС?
Kales can provide the agreed factory conformity documents, technical specifications, drawings, component data, and VIN information used by the buyer’s accredited certification body and customs broker. Final ОТТС and ЭПТС acceptance depends on the applicable EAEU and national approval process; it is not guaranteed by a factory document package alone.
Which Central Asian border ports are available for delivery?
Kales can quote DAP delivery to Khorgos, Alashankou, Bakhtu, or Kashgar. TIR delivery to inland destinations such as Almaty or Tashkent can also be evaluated after the final dimensions, route, carrier, border procedure, and delivery term are confirmed.
Are local spare parts available?
The specification can use Weichai engines, FUWA/BPW/SAF axles, JOST landing gear, and WABCO brake components that have established service channels in many CIS markets. Buyers should verify the selected model and local distributor coverage before ordering; Kales can include a route-specific spare-parts kit in the quotation.
Request a DAP Khorgos or Alashankou Quotation
Send your destination country and city, cargo density, target payload, minimum operating temperature, tractor model and fifth-wheel height, preferred axle and suspension, unloading-site air-source details, order quantity, and requested delivery term. The Kales Central Asia team will prepare a USD or RMB quotation, technical configuration, and document-scope checklist.
