Hyster partnered with RICO to develop explosion-proof electric trucks for hazardous environments like oil refineries and chemical plants. These trucks integrate RICO’s ATEX-certified components with Hyster’s robust forklift designs, using lithium-ion batteries with intrinsic safety features. The collaboration focuses on thermal runaway prevention, spark-resistant motors, and reinforced enclosures to suppress explosions. Charging systems comply with IECEx standards, ensuring operation in Zone 1/21 areas.

What drove Hyster’s collaboration with RICO?
Hyster sought RICO’s expertise in ATEX-certified explosion-proof systems to expand into high-risk industrial markets. The partnership combined RICO’s safety engineering with Hyster’s material handling scalability, addressing demand for safer lithium-powered equipment.
RICO’s proprietary spark containment tech was critical—think of it like a car’s crumple zone, but for electrical arcs. Their motors use encapsulated windings and pressure-relief vents to neutralize ignition risks. Pro Tip: Always verify ATEX/IECEx certification labels on trucks operating in flammable atmospheres. For example, Hyster’s E50-70XD trucks with RICO systems handle ethanol processing facilities where traditional diesel forklifts pose explosion risks. A key advantage? Lithium-ion’s zero-emission operation eliminates exhaust sparks entirely.
What tech defines these explosion-proof trucks?
Core innovations include hermetically sealed battery compartments, intrinsically safe circuits limiting energy below ignition thresholds, and temperature-controlled PWM motor drivers. These systems prevent sparks during abrupt load changes or brake regeneration.
Lithium batteries here aren’t your average cells—they’re modified with ceramic separators and pressure-tolerant casings. If a cell faults, how does it avoid chain reactions? Redundant fusing and gas-vent channels redirect thermal energy away from flammable zones. Practically speaking, these trucks work like a submarine’s airlock: isolating hazards layer by layer. Pro Tip: Opt for LiFePO4 chemistry here—its higher thermal runaway temperature (270°C vs. NMC’s 150°C) adds critical safety margins.
| Feature | Hyster-RICO | Standard EV |

| Circuit Voltage | <30V | 48-80V |
| Certifications | ATEX, IECEx | CE/UL |
How do these trucks exceed safety standards?
They implement three-layer protection: mechanical containment, electronic current limiting, and chemical suppression. This multi-barrier approach ensures fail-safety even if two systems malfunction.
Consider the battery enclosure—it’s not just sealed; it’s pressurized with inert nitrogen to starve potential fires of oxygen. Why does this matter? In grain silos, airborne dust can ignite at 1mJ—50x lower than gasoline vapors. RICO’s solution? Enclosures withstand 8-bar explosions internally, while external sensors trigger shutdowns at 20% LEL (Lower Explosive Limit). Pro Tip: Schedule bi-annual gas testing on battery vents—contamination from hydrogen sulfide can degrade safety buffers.
| Risk | Mitigation | Testing Interval |
|---|---|---|
| Electrical Arcing | Silver-coated relays | 500h |
| Thermal Runaway | Coolant jackets | 6 months |
| Gas Infiltration | Positive pressure | Continuous |
What industries benefit most from this partnership?
Pharmaceuticals, petrochemicals, and waste treatment plants gain the most, where volatile organic compounds (VOCs) necessitate explosion-proof logistics. These sectors often face OSHA/NEC mandates for certified equipment in classified zones.
Take biogas facilities—traditional ICE forklifts risk igniting methane leaks. Hyster-RICO trucks eliminate that via electric drivetrains and hermetically sealed switches. But aren’t electric motors inherently safer? Not entirely—brushless motors can still arc during regenerative braking. That’s where RICO’s dynamic voltage clamping enters, capping back-EMF spikes to <10V. For operations in paint spray booths, these trucks reduce insurance premiums by 15-30% via risk mitigation.

FAQs
Yes, with optional H2 sensors and palladium-coated connectors that prevent catalytic ignition—critical for fuel cell facilities.
Are battery swaps safe in Zone 1 areas?
Only using Hyster’s pressurized swap stations—external swaps risk ambient gas exposure during disconnection.
Do these trucks cost more than diesel counterparts?
Upfront costs are 40% higher, but TCO drops 30% via reduced maintenance and hazard pay eliminations.
