Product Overview

Engineered for the toughest outdoor material handling challenges, the H-Series 2.5T Dual Fuel Forklift breaks free from single-energy dependency. Its standout capability: one machine, two fuel options — LPG (liquefied petroleum gas) and CNG (compressed natural gas) — switchable on the fly based on local supply conditions and price dynamics. This dual-fuel architecture gives fleet managers genuine energy cost control rather than being at the mercy of one fuel market.

Under the hood, an internal combustion powertrain delivers 16 kN of peak traction force and an industry-leading 18% full-load gradeability, paired with pneumatic tires (front: 21×7-15, rear: 18×7-8) that bite into gravel, mud, and wet surfaces with confidence. The 3,680 kg curb weight and 1,650 mm wheelbase provide a 1.47:1 weight-to-load ratio — well above the 1.3:1 industry norm — ensuring rock-solid stability even when fully loaded at height.

Mast options span 3,000 to 6,000 mm lift height with a retracted height of just 2,080 mm, allowing the truck to pass through standard doorways and container openings. This is a forklift designed for yards, quarries, ports, and construction sites where conditions are rough, slopes are steep, and downtime is not an option.

FAQ

Q1: Can I switch between LPG and CNG while the forklift is moving? A: Yes. The dashboard-mounted fuel selector allows on-the-go switching. The engine transitions automatically between fuel sources within 5 seconds — no stopping, no manual adjustment required.

Q2: Is dual-fuel maintenance more expensive than diesel? A: Actually less expensive. Gas-fuel engines produce virtually no carbon deposits, and oil contamination is far lower than diesel engines. Service intervals extend to 500 hours (vs. 250 for diesel), and there are no diesel-specific components like injectors or turbochargers to maintain.

Q3: What about flat tires with pneumatic tires? A: The front tires use a wide 21×7-15 specification with even pressure distribution, resulting in very low puncture rates in normal use. For extreme environments (metal scrap yards, glass factories), optional solid tires are available — though with some trade-off in ride comfort.

Q4: How long does a CNG tank last during operation? A: A standard 80L CNG cylinder provides approximately 6–7 hours of continuous loaded operation. LPG cylinder runtime is similar. Exact duration depends on load weight and duty cycle intensity.

Q5: Can this forklift work indoors? A: Short-duration indoor use is acceptable with adequate ventilation. Gas-fuel exhaust produces near-zero particulates compared to diesel. For prolonged enclosed-space operation, we recommend adding a catalytic exhaust purifier or considering our pure-electric models.

Q6: What is the warranty policy? A: Complete vehicle: 1 year / 2,000 hours (whichever comes first). Engine and transmission core powertrain: 2 years / 4,000 hours (whichever comes first).

Key Highlights

Highlight 1: LPG/CNG Dual Fuel — Energy Independence, Cost Control

Feature: Single engine platform compatible with both LPG and CNG, switchable via dashboard control during operation
Benefit: Never locked into one fuel supply chain — switch to whichever gas source is cheaper or available, reducing annual fuel expenditure by 15–25%
Use Case: A building materials yard in northern China switches from LPG to CNG during winter price spikes, saving ¥45,000 annually per unit

Highlight 2: 16 kN Traction + 18% Gradeability — Conquer Any Terrain

Feature: IC powertrain producing 16 kN maximum traction force, 18% full-load climbing capability
Benefit: Haul 2.5-ton loads up steep gravel ramps at ports and quarries without wheel spin or rollback — a safety margin that electric and lighter IC models simply cannot match
Use Case: Container terminal access roads with sustained 15% gradients — this truck climbs them loaded without breaking stride

Highlight 3: Pneumatic Tires — All-Terrain Grip, Cargo Protection

Feature: Front 21×7-15 / Rear 18×7-8 pneumatic tire configuration with 1,000 mm front track width
Benefit: 40%+ better traction on loose surfaces vs. solid tires, plus natural vibration damping that protects fragile cargo from road shock
Use Case: Ceramic tile distribution yards where road vibration cracks tiles — pneumatic tires reduce breakage rates from 3% to under 0.5%

Highlight 4: 3,680 kg Curb Weight — Stability You Can Trust

Feature: Heavy-duty chassis with 1,650 mm wheelbase and 500 mm load center
Benefit: 1.47:1 weight-to-load ratio prevents rear-end lift and side tipping, critical for outdoor work in crosswinds or on uneven ground
Use Case: Coastal port operations where wind gusts challenge lightweight forklifts during high-rack stacking

Highlight 5: Cold-Weather Reliability — Start When Diesel Can't

Feature: Gas-fuel engines with no diesel waxing or gelling issues at sub-zero temperatures
Benefit: Reliable cold starts down to -20°C without block heaters or fuel additives — critical for northern-region operations where diesel fleets lose hours every winter morning
Use Case: Harbin construction yards at -15°C — dual fuel forklift starts and reaches full power within minutes, while diesel competitors sit idle waiting for warm-up

Pain Point Solutions

Buyer Pain Point	How H-Series Dual Fuel Solves It
Diesel price volatility makes budgeting impossible	Switch to LPG or CNG based on real-time pricing — annual fuel cost 20–35% below diesel equivalents
Slopes and rough terrain stall ordinary forklifts	18% gradeability + 16 kN traction + pneumatic tire grip = loaded climbing on gravel, mud, and wet ramps
Single fuel supply disruption halts the entire fleet	Dual fuel = dual insurance. If one gas source is cut off, the other takes over instantly — zero fleet downtime
Fragile cargo damaged by road vibration on uneven ground	Pneumatic tires absorb 60%+ of road shock energy, cutting transport damage rates for ceramics, glass, and building materials
Diesel forklifts won't start in winter cold	Gas fuel doesn't gel or wax below freezing — reliable -20°C cold starts with zero warm-up delay
