Exploring the heavy end of compact electric loaders: the XHD15, XHD20 (2T, 32km/h, 153.6V 460Ah), and XHD25T telescopic (3800mm dump). High-voltage powertrains for serious construction work. CE Certified.
Introduction: Beyond the Garden Gate
The previous articles focused on the "compact and micro" end of the spectrum—machines for gardens, basements, and tight urban alleys. But what happens when the job site scales up? When you need to load 6-yard dumpsters, move 2 tons of aggregate, or work 8 hours straight on a rural road project?
This is where the Xinghang Heavy Duty Electric Series enters. The XHD15 (1.5T), XHD20 (2T), and XHD25T (2.5T Telescopic) are not scaled-up toys; they are structurally reinforced, high-voltage (153.6V) professional machines designed to directly replace diesel loaders in mid-size construction, quarry auxiliary, and heavy material handling.
They represent a shift from "accessibility" (fitting through doors) to "productivity" (cycling heavy loads at speed). With features like dual 25kW working motors, 35kW travel motors, DE20 high-low transmissions, and 153.6V 300–460Ah LiFePO? packs, these machines target contractors who want zero emissions without sacrificing the brute force of diesel.
1. The 153.6V High-Voltage Architecture: Why It Matters
Light-duty loaders (XHD400/XHD500) operate on 60V or 64V systems. They are efficient for their size, but to push 2 tons of material or climb a 15° grade with a full bucket, you need voltage—and lots of it.
The XHD15, XHD20, and XHD25T utilize a 153.6V nominal system (likely a 48-cell LiFePO? configuration at 3.2V/cell × 48 = 153.6V).
Efficiency: High voltage allows for lower current to deliver the same power (P=VI). Lower current means thinner, lighter cabling and reduced resistive heat loss in the motors and controllers. This is critical for sustaining heavy loads without thermal derating.
Power Density: The XHD20 features a 35 kW travel motor and dual 25 kW working motors (50 kW combined hydraulic drive). Delivering this kind of power at 72V would require massive current (over 480 Amps continuous), which is impractical for connectors and wiring. At 153.6V, the current is halved, making the system manageable and reliable.
Charge Rate: The 153.6V system supports high-power charging (e. g., 100A charger mentioned in specs), allowing for faster turnaround. The XHD20 charges from 20% to 100% in approximately 4 hours 50 minutes with the high-amperage charger.
2. XHD20: The 2-Ton Workhorse (Deep Dive)
The XHD20 is arguably the flagship of the heavy series. It is built to compete head-to-head with entry-level diesel loaders (like the Bobcat S450 or similar 2T class machines) but with the advantages of electric.
2.1 Specifications Snapshot
Operating Weight: 6500 kg (substantial counterweight for stability).
Rated Load: 2200 kg.
Bucket Capacity: 1.2 m3 (2000mm wide).
Max Dump Height: 3550 mm.
Travel Speed: 8 km/h (Low) – 32 km/h (High). Note: High speed is for site transit; low is for precise work.
Powertrain: 153.6V 460Ah LiFePO? (approx. 70 kWh usable).
Motors: 35 kW Travel / 25 kW×2 Working.
Transmission: DE20 High-Low Speed Gearbox (Front 2 / Rear 2 gears).
Tires: 16/70?20 (heavy-duty lug).
2.2 The Dual-Working-Motor Advantage
Most loaders use a single hydraulic pump motor. The XHD20 uses two 25 kW motors driving the hydraulic system.
Redundancy: If one circuit is under lower demand, the system optimizes; if both are needed, 50 kW of hydraulic power is available for simultaneous steering, lifting, and tilting under heavy load.
Thermal Management: Splitting the load between two motors keeps each unit cooler than a single 50 kW unit would be, extending motor life.
Breakout Force: The combined hydraulic flow and pressure (16 MPa system) driven by these motors enable the XHD20 to achieve the digging and lifting forces expected of a 2T class machine.
2.3 High-Low Transmission
Unlike lighter electric loaders that use direct drive, the XHD20 employs a DE20 gearbox.
Low Gear: Provides the torque multiplication needed for digging into a pile, pushing heavy material, or climbing grades with 2200kg in the bucket.
High Gear (32 km/h): Allows the machine to travel quickly between stockpiles and job sites on hard ground, reducing non-productive transit time. This is a rare feature in electric loaders, bridging the gap between "skid steer" and "utility tractor" capabilities.
3. XHD15: The Balanced 1.5T Entry
The XHD15 sits below the XHD20 but shares the same high-voltage DNA.
Weight: 3700 kg.
Load: 1500 kg.
Power: 20 kW Travel / 12 kW Working.
Battery: 153.6V 300Ah.
Dump Height: 2700–3200 mm.
Speed: 12 km/h.
It is the ideal "middle ground" for contractors who need more than 1T but find 2T excessive or too heavy for certain flooring/access points. It retains the 153.6V architecture and hydraulic braking, ensuring professional-grade reliability.
4. XHD25T: The Heavy Telescopic (2.5T Class)
The XHD25T takes the chassis and powertrain of the heavy series and adds a telescopic boom.
Weight: 5900 kg.
Capacity: 1000 kg (extended) / 2500 kg (class rating context).
Dump Height: 2800mm (retracted) / 3800mm (extended).
Reach: 1150mm (extended).
Powertrain: Identical to XHD20 (35kW travel, 25kW×2 working, 153.6V 460Ah).
This machine solves a specific problem: "I need to lift 2.5T class stability and electric power, but I also need to reach over a wall or into a high-sided truck." Standard 2T loaders max out at ~3500mm. The XHD25T stretches to 3800mm, making it viable for loading high-bed trailers or stacking heavy materials on second-tier racking, albeit with reduced capacity at full extension.
5. Application Scenarios for the Heavy Series
Municipal Road Work: The XHD20’s 32 km/h speed allows it to move between manholes or sidewalk sections quickly. Zero emissions allow work in populated areas without fumes.
Quarry / Aggregate Yards: Moving sand, gravel, or crushed stone. The 1.2 m3 bucket and 2200kg rating handle dense materials. The heavy weight (6500kg) provides traction.
Concrete Batch Plant Auxiliary: Loading mixers or moving pigments. Electric operation means no diesel contamination risk near food-grade or sensitive batching.
Industrial Site Prep: The XHD15 handles 1500kg pallets of steel or block. The ROPS/FOPS structure (implied by heavy class) protects the operator.
High-Stack Warehousing: The XHD25T places heavy pallets on high racks (3800mm reach) in electric-only environments (battery plants, indoor logistics).
6. Maintenance: Simplifying the Heavy Machine
Even at 2T–2.5T class, the electric advantage holds:
No Diesel Engine: No DPF regeneration, no fuel filters, no injectors, no glow plugs, no oil changes for the prime mover.
Regenerative Braking: The electric motor acts as a generator during deceleration, reducing wear on the hydraulic brakes (drum type) and saving energy.
Simplified Drivetrain: The DE20 gearbox is robust, but without the complexity of a diesel torque converter or wet clutch packs found in some hydrostatic diesels.
Centralized Cooling: Automatic temperature-controlled cooling for motors and controllers, monitored via the dashboard (implied by heavy class specs).
Conclusion: Diesel Performance, Electric Soul
The Xinghang XHD15, XHD20, and XHD25T prove that "compact electric" does not have to mean "light duty." With 153.6V architectures, dual high-kW motors, high-low transmissions, and weights exceeding 6.5 tons, these machines deliver the cycle times, breakout forces, and durability required on serious job sites.
They offer the contractor a choice: continue battling diesel maintenance and emissions regulations, or switch to a heavy electric loader that works as hard as the old iron—but cleaner, quieter, and often cheaper to run.
