Chassis & Running Gear
Axle & Braking System
This trailer is equipped with four ZONXIN 10-ton disc brake axles, featuring a 1st and 4th axle lift system for improved maneuverability and reduced tire wear during empty runs. The braking system incorporates KORMEE EBS (Electronic Braking System) in a 4S/2M configuration, ensuring precise, responsive braking under all load conditions. With 8 dual-chamber air brakes and WABCO relay valves, safety is never compromised.
Suspension
The ZONXIN air suspension system provides a smoother ride, better load distribution, and reduced road damage — a critical advantage when transporting sensitive liquid cargoes.
Wheels & Tires
•Tires: Linglong brand 385/65R22.5 — 8 mounted + 2 spares = 10 total
•Rims: Aluminum alloy 11.75” — 8 mounted + 2 spares = 10 total
The large-diameter, low-profile tire configuration offers excellent stability and a lower center of gravity.
Tank Body Design
Material & Construction
Built entirely from high-grade aluminum alloy, this tanker delivers exceptional strength-to-weight ratio. The tank body and anti-surge baffles are 5.5mm thick, while the end plates are reinforced to 7mm for maximum structural integrity.
Compartment Configuration
The 40m³ tank is intelligently divided into 5 compartments:
Compartment
Volume
Manhole Position
1 5m³ Center
2 8m³ Center
3 10m³ Center
4 9m³ Center
5 8m³ Center
This multi-compartment design allows for simultaneous transport of different fuel grades or liquid products, maximizing operational flexibility.
Tank Shape
The tank features a front-tapered, rear-straight barrel design with a circular cross-section and gooseneck barrel with main beam frame structure. This aerodynamic profile reduces drag and improves fuel efficiency for the tractor unit.
Safety & Operational Features
Manholes & Venting
•5 European-standard manhole covers, each positioned at the center of its respective compartment
•Each manhole includes a built-in breathing valve for pressure regulation and vapor recovery
Discharge System
•5 × 4-inch aluminum alloy ball valves — one per compartment
•All discharge lines converge to a single 3-inch male coupling with end cap, located in the right-side mid-mounted valve box
•5 × 4-inch aluminum alloy emergency shut-off valves (subsea valves) for immediate flow isolation in emergencies
Valve & Tool Boxes
•Valve box: 1 aluminum box, right-side mid-mounted
•Tool box: 1 aluminum box, left-side mid-mounted
Discharge Hoses & Fittings
•Discharge hose boxes: 2 stainless steel boxes, 6-meter specification
•Discharge hoses: 2 hoses, 6-meter specification (5.5-meter actual length)
•Discharge hose couplings: 4 × 3-inch aluminum alloy couplings
Coupling & Support Equipment
Kingpin:90# / 50# assembly type
Landing Gear:28-ton single-action external type
Electrical Socket:Additional 15-pin socket (50# / 90#)
Electrical & Air Lines:Mounted beneath the front end plate baffle
Spare Tire:2 units
Spare Tire Rack:1 unit
Ladder:Rear-mounted
Tractor Unit Compatibility
