The S80-120FT forklift from the brochure specs offers a load capacity of 8,000–12,000 lbs (3.6–5.4 tons) with lift heights up to 248 inches. Powered by AC motors and LiFePO4 or lead-acid batteries, it features Mast Standard 3-stage (15–25 ft lift), a 24-inch load center, and travel speeds up to 9.7 mph. Attachments like side-shift forks expand flexibility in warehouses and docks.
48V 400Ah/420Ah Forklift Lithium Battery
What are the load capacity and lift height specifications?
The S80-120FT handles 8,000–12,000 lbs loads with a 24-inch load center. Its 3-stage mast achieves lift heights up to 248 inches (20.6 ft), ideal for stacking in high-rack warehouses. Lowered heights (90–106 inches) suit low-clearance docks. Pro Tip: Overloading beyond load center reduces stability—add counterweights for uneven loads.

When evaluating lift capacity, the S80-120FT’s specs adhere to ISO 10596 standards, factoring load moment and mast tilt angles. For example, a 10,000-lb load at 24 inches requires a forklift weight of 15,000+ lbs to prevent tipping. Why does lift height matter? Higher reaches demand slower ascent speeds (≤0.7 ft/sec) to avoid pendulum effects. A dual-cylinder hydraulic system ensures smooth lifting, but operators must monitor load shifts.
| Load Capacity | Max Lift Height | Load Center |
|---|---|---|
| 8,000–12,000 lbs | 248 inches | 24 inches |
| 9,000 lbs (at 24″) | 220 inches | 24 inches |
What power source options are available?
The S80-120FT supports LiFePO4 (48V 400–630Ah) or lead-acid batteries. LiFePO4 offers 2,000+ cycles, 2-hour charging, and 30% weight savings. Lead-acid provides lower upfront costs but requires daily watering. Pro Tip: Use LiFePO4 for multi-shift operations—no equalization needed.

Beyond voltage specs, LiFePO4 batteries, like Redway’s 48V 600Ah/630Ah Forklift Lithium Battery, deliver 8–10 hours runtime and maintain 80% capacity after 3,000 cycles. Lead-acid alternatives need 8–10 hours charging and suffer sulfation if undercharged. How do temperature extremes affect performance? LiFePO4 operates at -4°F to 140°F (-20°C to 60°C) with <5% capacity loss, while lead-acid loses 50% at freezing temps. Transitional phrases help connect specs to real-world use: "For instance, a 48V 400Ah LiFePO4 pack supports two full shifts in a refrigerated warehouse."
| Power Source | Cycle Life | Charge Time |
|---|---|---|
| LiFePO4 | 2,000–3,000 | 1.5–2 hours |
| Lead-Acid | 1,000–1,500 | 8–10 hours |
What mast configurations and attachments are supported?
Standard 3-stage masts (15–25 ft lift) dominate, while duplex masts optimize low-clearance. Attachments include side-shift forks, carton clamps, and drum handlers. Pro Tip: Avoid mast modifications without OEM approval—improper welding weakens structural integrity.
Mast specs vary by lift height and free lift. For example, a 3-stage mast with 80 inches free lift allows height adjustment without mast extension, critical for confined spaces. But what if you need lateral flexibility? Side-shift forks (±6 inches) align uneven pallets but add 200–400 lbs, reducing net capacity. A real-world analogy: Using a duplex mast in a 10-ft warehouse is like switching to a sports car—lower profile, faster maneuverability.
How does travel speed and braking performance affect operations?
Loaded travel reaches 8.7 mph, unloaded up to 9.7 mph. Regenerative braking recovers 10–15% energy on deceleration. Pro Tip: Test braking distances on inclines—grades >5% require 3x stopping distance.
The S80-120FT’s AC motor provides precise torque control, but speed isn’t just about productivity—it’s safety. For instance, stopping a 10,000-lb load at 8 mph requires 15–20 feet on dry concrete. Wet surfaces? Double that. Why use regenerative braking? Beyond energy savings, it reduces brake pad wear by 40%. Transitional phrases link specs to outcomes: “Practically speaking, regenerative systems are a must for facilities prioritizing efficiency and maintenance costs.”
What safety features are included in the S80-120FT?
Standard safety includes seatbelt interlock, emergency reverse braking, and LED lights. Optional features: automatic speed reduction on turns, load backrest extensions. Pro Tip: Train operators on stability indicators—alarms won’t prevent reckless driving.
The seatbelt interlock halts movement if unbuckled, but operators often bypass sensors. How to mitigate this? Pair with speed limiters (5 mph in pedestrian zones) via geofencing. Load backrest extensions prevent items falling backward, crucial for irregular shapes. Real-world example: A dockworker avoiding backrests saw a 20% increase in load drops.
What maintenance intervals and costs should operators expect?
LiFePO4 models require 50% less maintenance vs. lead-acid. Inspect hydraulics every 500 hours, tires every 250. Pro Tip: Log motor temps—AC units overheating >176°F signal bearing failure.
With LiFePO4, electrolyte checks and terminal cleaning vanish, saving $1,200+ annually. However, hydraulic leaks still account for 60% of downtime. A real-world cost analogy: Skipping a $200 hose replacement can lead to a $3,000 pump failure. Why track tire wear? Solid pneumatic tires lose 10% traction after 2,000 hours, increasing slip risks. Transitional phrases bridge specs to budgets: “In essence, upfront LiFePO4 costs are offset by 3-year maintenance savings.”
