The SAGMOTO X6s is the premium 8x4 heavy-duty dump truck platform in the Fenghan Trading export portfolio, positioned above the X3s as the go-to choice for operators who need higher payload envelopes, stronger driveline components, and a more comfortable operator environment for extended shift cycles. With GVWR ratings from 31 to 40 metric tons and Weichai WP12 powertrains delivering up to 480 horsepower, the X6s is purpose-built for large-scale mining, infrastructure earthmoving, and heavy construction logistics where downtime is measured in lost revenue per hour.
Platform Overview and Positioning
Within the SAGMOTO product hierarchy, the X6s sits between the X3s (volume platform, 20-30T off-road payload) and the X9 series (premium tractor and specialty platform). The X6s is exclusively an 8x4 configuration, meaning it has two steering axles at the front and two driven axles at the rear. This layout provides a higher legal GVW on paved roads (important for mixed on-road/off-road operations) while retaining the off-road traction needed on mine haul roads and construction sites.
Engine and Powertrain
The X6s is equipped exclusively with Weichai WP12 series engines, as the WP10 displacement is insufficient for the higher GVW envelope. Two power ratings are offered, each calibrated for different duty profiles.
| Specification | WP12.460 | WP12.480 |

| Compression Ratio | 17.5:1 | 17.5:1 |
| Boost Pressure | 2.8 bar (wastegate turbo) | 3.0 bar (wastegate turbo) |
| Fuel Consumption (BSFC) | 195 g/kWh @ rated power | 198 g/kWh @ rated power |
| Oil Capacity | 28 L (with filter) | 28 L (with filter) |
| Coolant Capacity | 42 L | 42 L |
| B10 Life | 1,200,000 km | 1,200,000 km |
Both engines are available in EURO III (mechanical pump) or EURO V (SCR + common rail) configurations. For export markets without strict emissions regulations, the EURO III variant is preferred because it eliminates the urea (AdBlue) supply chain dependency and reduces maintenance complexity. For markets with EURO V requirements (Turkey, Russia Eurasian Customs Union, select Middle East markets), the SCR system uses a 40-liter urea tank providing approximately 3,500 km of range at standard consumption rates.
Transmission System
The X6s is equipped with the Fast Gear 12JS160TA transmission, a 12-speed manual with synchronized forward gears and a crawler gear. An automated manual transmission (Fast Gear 12JZ160) is available as an option, using a pneumatic actuator for clutch and shift operations controlled by a TCU (Transmission Control Unit) that receives input from engine speed, output shaft speed, and gradient sensors.
| Parameter | 12JS160TA (Manual) | 12JZ160 (AMT) |
|---|---|---|
| Forward Gears | 12 (including crawler) | 12 (including crawler) |
| Reverse Gears | 2 | 2 |

Axles, Suspension, and Brakes
The X6s uses a Hande axle set that draws on MAN axle technology. The front twin steering axles are both rated at 7,500 kg each (15,000 kg total front axle capacity), and the rear tandem is rated at 16,000 kg per axle (32,000 kg tandem). The rear axle uses a hub-reduction design for increased ground clearance and torque multiplication at the wheel, which is essential for launch on steep gradients at full GVW.
The front suspension uses parabolic leaf springs with telescopic shock absorbers on both steering axles. The rear suspension is available in two configurations: a standard 13-leaf progressive spring pack for mixed on-road/off-road duty, and a heavy-duty 16-leaf variant with reinforced spring eyes for dedicated mining operations. A load-sensing ride-height valve is fitted to the rear suspension on AMT-equipped models, providing the TCU with rear axle load data for shift-point optimization.
The braking system uses dual-circuit air brakes with a WABCO or KNORR air dryer and four-circuit protection valve. Front brake drums are 410mm diameter, and rear drums are 410mm with larger friction area for the higher GVW. Spring brake chambers on the rear axles provide parking brake function. An ABS system is standard on all export models, and an optional ESC (Electronic Stability Control) system is available for markets requiring it.
Chassis Frame and Tipper Body
The X6s frame uses a double-layer ladder construction with 320mm main rails (8mm inner + 6mm outer web), providing a section modulus of 1,620 cm3 — approximately 9 percent higher than the X3s. The higher section modulus is necessary to accommodate the 8x4 wheelbase (1,800 + 3,200 mm) without frame flex that could compromise tipper body alignment and cause premature hinge wear.
The tipper body is manufactured from Hardox 450 wear-resistant steel with the following standard thicknesses: floor 10mm, side walls 8mm, front wall 6mm. Three body geometries are available — rectangular (general construction), U-body (sticky materials, wet clay, ore), and semi-U (mixed duty). The body is lifted by a 4-stage telescopic hydraulic cylinder mounted at the front of the body, driven by a PTO-mounted gear pump.
| Body/Frame Parameter | Specification |
|---|---|
| Frame Material | Q690 high-tensile steel, yield 700 MPa |
| Frame Height x Web | 320mm x (8+6)mm double-layer |
| Body Material | Hardox 450 (or HB450 equivalent) |
| Body Floor Thickness | 10mm |
| Body Volume Range | 16-24 m³ |
| Hydraulic Cylinder | 4-stage telescopic, front mount |
| Lift Time (loaded) | 22 seconds to 50° |
| System Pressure | 22 MPa (220 bar) |
Cab and Operator Environment
The X6s cab is a significant upgrade over the X3s platform, featuring a wider interior (2,400mm vs 2,280mm), improved sound insulation reducing interior noise to 73 dB(A) at 60 km/h, and a standard 7-inch multi-function display. The driver seat is an ISRI-brand air-suspended seat (imported for export models) with lumbar support, armrest, and three-point belt with pre-tensioner. The cab is mounted on four-point hydraulic isolation mounts rather than the rubber blocks used on the X3s, which reduces transmitted vibration by approximately 35 percent.
Air conditioning is standard with dual-zone temperature control (driver and passenger), rated for ambient temperatures up to 55°C. The cab includes a single sleeping berth (lower), with an optional upper berth for relay driving operations. The dashboard features storage compartments, cup holders, and a 12V power outlet as standard. A 220V inverter (300W) is available as an option for powering laptops and communication equipment.

Frequently Asked Questions
What is the fuel consumption of the X6s in mining operations?
In typical open-pit mining duty cycles (2-3 km haul, 30T payload, 8% average gradient, 25-30 cycles per 10-hour shift), the X6s with WP12.460 consumes approximately 55 to 65 liters of diesel per 100 km, or roughly 3.0 to 3.5 liters per loaded cycle. The WP12.480 variant consumes 3 to 5 percent more fuel but completes cycles approximately 8 percent faster due to higher torque output, resulting in similar per-ton fuel costs.
Is the X6s available with a Cummins engine?
The X6 platform (X6, not X6s) is the Cummins-powered variant in the SAGMOTO lineup. The X6s uses Weichai engines exclusively. Fleet operators who require Cummins engines for global parts standardization should consider the X6 instead. The X6s and X6 share the same chassis, cab, and body options — the difference is purely the powertrain.
What spare parts should be stocked for a 10-unit X6s fleet?
For a 10-unit fleet operating at 6,000 hours per year, we recommend maintaining stock of: WP12 engine filters (oil, fuel, air — 6 month supply), clutch assembly (2 units), transmission synchronizer rings (1 set), brake drum/shoe sets (4 units), hydraulic cylinder seal kits (3 sets), and a complete PTO pump assembly (1 unit). The total recommended parts inventory value is approximately USD 15,000-20,000, representing 3-4 percent of fleet acquisition cost.
Conclusion
The SAGMOTO X6s is the definitive choice for fleet operators who need the maximum legal GVW and off-road payload in an 8x4 configuration without stepping up to the premium Cummins-powered X6. Its Weichai WP12 powertrain is proven across millions of kilometers of mining and construction service, the Fast Gear 12-speed transmission offers both manual and AMT options, and the reinforced chassis and Hardox body deliver the durability needed for the toughest job sites. For fleet buyers evaluating the X6s, the key decision points are engine power (460 vs 480 HP), transmission type (manual vs AMT), and body geometry (rectangular vs U-body vs semi-U) — all of which should be matched to the specific duty cycle and material profile of the intended operation.
