The H40-70FT IC Pneumatic Forklift series offers load capacities from 4,000 to 7,000 kg, powered by robust diesel/LPG engines (45–63 kW) for heavy outdoor tasks. Key specs include pneumatic tires (28×9-15 front/21×8-15 rear), dual-stage mast lifts up to 6.5m, and travel speeds up to 24 km/h. Advanced safety features include load-sensing hydraulics and ROPS/FOPS-certified cabins for warehouse/logistics durability.

What load capacities does the H40-70FT series cover?
The H40-70FT handles 4–7 metric tons, ideal for lumberyards and container handling. Models scale in 500 kg increments (H40=4T, H70=7T), with overload protection up to 110% via hydraulic derating. Pro Tip: Avoid sideloading >15°—uneven weight shifts risk tire slippage on slopes.

Built for rugged terrain, these forklifts use reinforced chassis and dual-differential axles to stabilize 7T loads. For example, the H70FT lifts steel coils to 4.5m heights without counterweight adjustments. But how do operators maintain stability? The system auto-reduces lift speed if the load center exceeds 600mm. Transitioning to hydraulics, the gear pump delivers 180 L/min flow—30% faster than standard IC models—cutting pallet cycle times by 8–12 seconds.
| Model | Capacity | Lift Height |
|---|---|---|
| H40FT | 4,000 kg | 5,500 mm |
| H70FT | 7,000 kg | 6,500 mm |
What engine options are available?
The H40-70FT uses Kubota V3800 diesel or Mitsubishi 4G94 LPG engines, generating 62–84 HP. Diesel variants offer 310 Nm torque for ramp climbs up to 25% gradient.

Designed for 10–14 hour shifts, the Kubota V3800 engine reduces fuel consumption by 18% via turbocharged intercooling. But what if operators need emission compliance? The LPG model meets EPA Tier 4 standards with particulate filters. Practically speaking, diesel suits outdoor yards due to higher torque, while LPG excels indoors with cleaner output. A 60-liter fuel tank provides 6–8 hours runtime, but idling longer than 20 minutes triggers auto-shutdown to conserve resources. Pro Tip: Use synthetic 10W-40 oil to extend engine life by 300–400 hours between services.
How do pneumatic tires impact performance?
The 28×9-15 front tires offer superior traction on gravel/mud, with 8-ply ratings resisting punctures. Rear tires (21×8-15) optimize turning radius at 3.2m, critical in tight docks.
Pneumatic tires absorb 70% more shock than cushion types, protecting loads on uneven ground. For instance, handling concrete slabs on construction sites becomes smoother, reducing product damage claims by 15–20%. However, these tires require 35 PSI checks weekly—underinflation causes 10–12% drag, burning extra 0.8L fuel/hour. Transitioning to maintenance, the deep treads need rock extraction after off-road use to prevent premature wear.
| Tire Type | Surface | Pressure |
|---|---|---|
| Pneumatic | Outdoor/Rough | 35 PSI |
| Cushion | Indoor/Smooth | N/A |

FAQs
Yes, but only with quad-mast attachments—the standard dual-stage mast lacks lateral reach beyond 4m. Always consult load charts for racking configurations.
Are these forklifts suitable for freezing temps?
Diesel models operate down to -20°C with block heaters. LPG loses efficiency below -10°C due to vaporization issues.
What’s the service interval for hydraulics?
Replace hydraulic filters every 1,000 hours—contaminated oil causes valve sticking and 20% slower lift speeds.
