What Is The E2.2-3.5XN 4-Wheel Forklift Truck?

The E2.2-3.5XN 4-Wheel Forklift Truck is a specialized industrial vehicle designed for narrow mining tunnels and underground operations. Engineered with a compact chassis and wet-brake system, it handles 3.5-ton loads in confined spaces like mines or hydropower tunnels. Key features include all-terrain stability, compliance with mining safety standards (e.g., explosion-proof certifications), and enhanced maneuverability for transporting ores, debris, or construction materials.

How to Jumpstart a Forklift Safely and Effectively

What defines the E2.2-3.5XN’s structural design?

Built with a reinforced steel frame and articulated steering, this forklift prioritizes durability in harsh environments. Its narrow body width (~1.2m) allows operation in low-clearance tunnels, while 4-wheel drive ensures traction on steep inclines. Pro Tip: Regularly inspect the chassis for stress fractures caused by uneven terrain.

The E2.2-3.5XN uses a monocoque structure with 10mm thick wear plates protecting critical components. Hydraulic dampers absorb shocks during off-road travel, reducing maintenance needs. For example, in limestone mines, its 28° approach angle prevents undercarriage scraping when navigating rocky surfaces. But how does it balance load capacity with compactness? Engineers achieve this through a rear-mounted counterweight and low-center-of-gravity battery placement. Warning: Overloading beyond 3.5 tons risks bending the rear axle.

What power systems drive the E2.2-3.5XN?

A 63kW diesel engine or optional lithium battery pack powers this model. The diesel variant offers extended runtime (8–10 hrs/tank), while electric versions provide zero emissions for enclosed spaces. Transitional torque management prevents wheel spin during acceleration.

The diesel engine couples with a 4-speed automatic transmission, delivering 420Nm peak torque at 1,800 RPM. Electric models use dual 30kW PMSM motors with regenerative braking, recovering 15–20% energy during descents. Why choose electric for underground use? Battery versions eliminate exhaust ventilation costs in tunnels. For instance, Jinchuan Group deployed 20 electric E2.2-3.5XN units, cutting ventilation expenses by ¥300,000/month. Pro Tip: Electric models require IP67-rated battery enclosures to withstand mine water exposure.

What safety features are critical for mining operations?

ROPS/FOPS-certified cabin and methane detectors ensure operator safety in explosive atmospheres. Dual-circuit brakes provide redundancy during emergency stops.

The cabin features tempered glass with 5mm polycarbonate layers to resist flying debris. Methane sensors trigger automatic shutdown at 1% gas concentration, exceeding China’s GB16423-2020 mining standards. What if visibility drops in dusty tunnels? Integrated LED floodlights (12,000 lumens) and thermal cameras detect obstacles up to 30m ahead. Example: At the Sichuan coal basin, these systems reduced collision incidents by 43% in 2023. Pro Tip: Monthly calibration of gas sensors is mandatory to maintain compliance.

How does it handle material transport in tight spaces?

Its 4-way steering modes (crab, pivot, 2WS/4WS) enable precise maneuvering. The hydraulic lifting mechanism reaches 3m heights with ±2mm positioning accuracy.

The crab steering mode allows diagonal movement—ideal for aligning with conveyor belts in 2.5m-wide tunnels. Load tests show 98% stability when carrying 3 tons on 15° slopes. But how quickly can it cycle loads? Advanced models achieve 25 cycles/hour via automated pallet recognition. For example, Yunnan Copper Mine reported a 30% efficiency gain after adopting automated E2.2-3.5XN units. Warning: Manual override is required when handling irregularly shaped cargo.
