The HY55-PT pallet truck is an electric walk-behind model with a 5,500 lb load capacity, powered by a 24V or 48V lithium-ion battery (typically 200–300Ah). It features a low-profile design (6″ clearance) for tight spaces, travel speeds up to 4 mph, and regenerative braking. Standard specs include IP54 waterproofing, 10-hour runtime, and LiFePO4 compatibility. Ideal for warehouses, docks, and retail logistics.

What are the load capacity and dimensions of the HY55-PT?
The HY55-PT handles 5,500 lbs max with fork dimensions of 27″W x 48″L. Its compact build (67″ overall length) ensures maneuverability in aisles under 7ft. For example, lifting 40 stacked pallets/day (2,200 lbs each) won’t strain its dual hydraulic pumps. Pro Tip: Never exceed 80% load capacity on ramps—lithium batteries drain faster under strain.

Technical specs include 1.5″ thickened steel forks and a 3-stage mast reaching 7.5ft. But how does this compare to similar models? The HY50-PT maxes at 4,850 lbs, while competitors like the Crown PT20 handle 4,400 lbs. Think of the HY55-PT as a “heavy-duty pickup” versus “sedans”—it trades compactness for brute strength. Transitionally, warehouses needing high-density lifts benefit most.
| Model | Capacity | Fork Length |
|---|---|---|
| HY55-PT | 5,500 lbs | 48″ |
| HY50-PT | 4,850 lbs | 42″ |
| Crown PT20 | 4,400 lbs | 36″ |
What battery and charging system does the HY55-PT use?
The HY55-PT supports 24V/200Ah or 48V/300Ah lithium batteries, achieving 8–10 hours per charge. Chargers use 10A CC-CV cycles (0–100% in 5–6 hours). For instance, a 48V LiFePO4 pack provides 14.4kWh—enough to move 25+ pallets daily. Pro Tip: Avoid chargers without temperature sensors; lithium cells degrade if charged below 32°F.

Battery specs include 2,000+ cycles at 80% DoD and CAN-Bus communication for real-time diagnostics. Why does voltage matter? Higher 48V systems reduce current draw, extending motor life by 30% compared to 24V. Transitionally, warehouses with multi-shift ops should opt for 48V for faster recharge during breaks. A typical analogy: 48V is like a highway (efficient for long distances), while 24V resembles stop-and-go traffic.
| Battery Type | Voltage | Cycle Life |
|---|---|---|
| LiFePO4 | 48V | 2,500+ |
| NMC | 48V | 1,200 |
| Lead-Acid | 24V | 500 |
How does the HY55-PT enhance maneuverability?
It uses pivoting tiller heads with 180° rotation and 6″ wheelbases for zero-turn capability. The 4 mph speed is controllable via thumb throttles—ideal for narrow aisles. Imagine threading a needle: the HY55-PT’s 43″ turning radius lets it navigate racks spaced just 6ft apart. Pro Tip: Lubricate pivot joints monthly to prevent stiffness in cold storage.
Features include auto-braking on inclines over 5° and LED headlights for low-light areas. But what happens if the tiller malfunctions? The backup manual hydraulic pump allows limited lifts, though at 50% slower speeds. Furthermore, its polyurethane wheels minimize floor scuffing—crucial for epoxy-coated surfaces. Transitionally, this design suits both grocery warehouses and automotive plants with mixed terrain.
What safety mechanisms are integrated?
The HY55-PT has emergency stop buttons, overload sensors, and tilt alarms. If the load shifts beyond 10° laterally, an alarm sounds and brakes engage. For example, unevenly stacked boxes trigger auto-lock before tip-overs. Pro Tip: Test tilt sensors quarterly using a 500-lb test load at varying angles.
Technically, the dual-circuit hydraulic system prevents sudden drops during power loss. Why is redundancy vital? In a refrigerated warehouse, condensation might short circuits—dual systems ensure failsafe operation. Additionally, the anti-rollback feature on ramps acts like a seatbelt, preventing backward slides. Think of it as an airplane’s redundant controls: essential for high-risk environments.
How does the HY55-PT compare to diesel-powered models?
Unlike diesel pallet trucks, the HY55-PT runs emission-free with 60% lower noise (65 dB vs. 95 dB). Maintenance costs drop 40%—no oil changes or exhaust filters. Picture a library vs. a construction site: the HY55-PT’s quiet operation suits indoor retail, while diesel dominates rugged outdoor yards. Pro Tip: Lithium batteries retain charge better in cold (down to -4°F) than diesel engines.
Key trade-offs: Diesel offers unlimited runtime via refueling but emits carcinogens. The HY55-PT’s 10-hour limit requires shift planning. Transitionally, food/pharma facilities favoring cleanliness benefit most. However, for 24/7 ports, hybrid models might bridge the gap. A cost example: HY55-PT saves $1,200/year in fuel but requires a $3k battery every 5 years.
What maintenance routines maximize HY55-PT lifespan?
Daily fork inspections for cracks and weekly battery terminal cleaning are critical. Lubricate mast chains every 500 operating hours—neglect risks jerky lifts. For instance, a distribution center using ISO-certified greases reported 20% fewer component replacements. Pro Tip: Use dielectric grease on battery connectors to prevent corrosion-induced voltage drops.
Advanced upkeep includes BMS firmware updates every 6 months and motor brush replacements at 2,000 hours. Why prioritize firmware? Updates optimize charge curves, preventing cell imbalance. Transitionally, proactive maintenance is like dental care—small efforts prevent major breakdowns. Replace hydraulic fluid annually; contaminated fluid is the #1 cause of pump failures, akin to clogged arteries in humans.

FAQs
Yes, but only with all-terrain tires (sold separately). Standard wheels are for smooth indoor surfaces—gravel or dirt risks motor debris ingress.
What’s the warranty period?
3 years for structural components, 1 year for electronics/battery. Extended plans cover hydraulic systems for up to 5 years.
