Axle Bulk Cement Tanker Semi Trailer

A 4 axle bulk cement tanker semi trailer is a pneumatic dry bulk tanker that carries cement, fly ash and mineral powder in a sealed V-shaped tank and pushes it out with compressed air instead of tipping. This Tongya unit runs a 50 m³ (50,000 L) V-shape tank on four 13-tonne axles with LINGLONG 12R22.5 tires, driven by an on-board Weifang Tianhe 4105P diesel engine and a 12 m³ Bohai twin-cylinder air compressor. Residual volume stays under 0.3%, so almost every kilo you load is a kilo you get paid for — and the extra axle keeps per-axle loading and tire wear under control on long, heavy cement and fly-ash hauls.

Why Fleet Operators Specify a 4 Axle Bulk Cement Tanker Semi Trailer

Three axles are enough for a 35–40 m³ cement bulker. Once you push tank volume past 50 m³ and start running 60–70 m³ class units, four axles stop being optional and start being commercial sense:

• More payload per trip, legally distributed. Four 13-tonne axle sets spread the same gross weight over more contact points, so each axle, tire and spring stays inside the limits your destination market enforces.
• Lower cost per tonne moved. A 50 m³ tank moves roughly a quarter more cement than a 40 m³ unit per trip — the same driver, the same fuel on many routes, fewer trips for the same tonnage.
• Better stability on site roads. The extra axle group shortens the load's unsupported span and steadies the trailer on the rutted, unpaved access roads typical of ready-mix plants and silo yards.
• Less tire punishment. With four axles the tire brand becomes a maintenance decision, not an afterthought — which is why this unit ships on LINGLONG 12R22.5 tires, with other brands selectable on request.

What You Can See on This Unit

Paint colour and rim colour are specified by the buyer; the unit photographed is finished in white with copper-gold rims, the configuration most fleet customers in dry-bulk work choose for heat reflection and easy dust inspection.

Technical Specifications

Component brands above are the factory standard package (JOST, WABCO, Bohai, Weifang Tianhe, ZY/FUWA/BPW axles as ordered). Tires, axles and suspension are configured against the axle-load rules of your destination country — send us the target market and we will size the tank and running gear accordingly.

Which Powders Can a Dry Bulk Cement Tanker Carry?

Any free-flowing, non-hazardous dry powder light enough to be fluidised by air works in this tanker. Typical cargoes our cement bulkers ship with:

• Cement — OPC, PPC and blended cement from plant to ready-mix batching plants and silos
• Fly ash — power-station ash for concrete and road-base projects (see our dry bulker tanker platform)
• Lime powder, mineral powder and chemical powders — with the tank sealed against moisture ingress
• Grain and food-grade dry bulk — where the customer specifies a food-compatible internal finish and cleaning regime

If your material is abrasive, hygroscopic or unusually dense, tell us the bulk density and we will adjust plate thickness, slope angle and compressor sizing instead of shipping a standard tank that under-performs.

Tank and Discharge System: Why the V-Shape Matters

Everything about pneumatic discharge comes down to how the powder behaves inside the tank. Our V-shape multi-chamber tank with an optimized internal slope keeps material moving toward the discharge points instead of packing into flat dead corners, and the whole welding process is done so the tank holds pressure without leaks.

• Sealed, welded tank body — machine welding that stays pressure-tight, so compressed air actually moves material rather than escaping through the seam
• Optimized slope and flow structure — lower centre of gravity, higher effective load, faster emptying
• 4-inch discharge line with auxiliary blower and wear protection — smoother, faster unloading at the receiving silo
• Residual volume under 0.3% — less product left behind per trip, less cross-contamination between loads

Customization Options

This trailer is built to order in our own plant, so the following are specification choices rather than aftermarket jobs:

• Tank capacity and shape — sized to your cargo density and legal payload
• Plate thickness — heavier plate for abrasive mineral powders
• Axles and suspension — 13 T axle sets, air or mechanical suspension, air-lift axles on request
• Tires and rims — 12R22.5 or 315/80R22.5, brand of your choice, single or dual fitment
• Paint and branding — powder coating with baking enamel in your colour, plus OEM brand lettering for distributors and dealers
• Discharge package — on-board engine and compressor, or PTO from the tractor

Factory-Direct from Tongya (CTAC TONGYA AUTO), Not a Trading Company

Tongya Automobile Co., Ltd has been building semi trailers and tanker trailers in Liangshan, Shandong since 1982, and has exported since 2005. When you buy this 4 axle bulk cement tanker semi trailer you are dealing with the works that welds the tank — not an intermediary re-selling someone else's trailer under a different badge. That matters in three practical ways: weld and pressure integrity are controlled in-house, customization is a drawing change rather than a negotiation with a third party, and spare parts and warranty claims come from the factory that built the unit.

• 400,000 m² manufacturing plant
• Since 1982 — more than four decades of trailer and tanker production
• Export experience across 50+ countries, with specs adapted to local regulations
• 12-month warranty and open invitation to 100% inspection before shipment
• Certified processes — ISO 9001:2015 and CCC
