IC forklifts with cushion tyres are internal combustion-powered material handling vehicles equipped with solid, non-pneumatic tyres designed for smooth indoor surfaces. These tyres—made from durable rubber—have a smaller diameter and wider tread to maximize stability in tight spaces like warehouses. Common fuel options include propane, diesel, or gasoline. They’re ideal for controlled environments, offering compact maneuverability and capacities ranging from 3,000 to 15,000 lbs.
How Much Do Different Forklift Batteries Weigh by Type?
What distinguishes cushion tyres in IC forklifts?
Cushion tyres on IC forklifts feature solid rubber construction with non-marking tread to prevent floor damage. Their compact design reduces the forklift’s turning radius by 15–20% compared to pneumatic tyres. Key metrics include 6–10 inch diameters and widths up to 12 inches for load distribution. Pro Tip: Always check tyre hardness (60–80 Shore A)—softer tyres grip better but wear faster on abrasive surfaces.

Beyond tread composition, cushion tyres lack air-filled chambers, eliminating puncture risks in debris-heavy environments. They’re often paired with a suspension-less chassis, relying on tyre compression (10–15 mm under max load) to absorb shocks. For example, a Toyota 8FGCU25 with cushion tyres maneuvers through 8-foot aisles effortlessly. But why avoid outdoor use? Uneven terrain can cause uneven wear or even axle misalignment. Transitional Note: While durable, these tyres require regular cleaning—grime buildup reduces traction by up to 40%.
How do cushion tyres improve indoor forklift performance?
Cushion tyres enhance indoor performance through space-efficient turning and consistent floor contact. Their slim profile lowers the forklift’s overall height by 8–12 inches, enabling entry into standard loading docks. Tests show they reduce lateral sliding by 30% on epoxy floors compared to pneumatics. Pro Tip: Rotate tyres every 500 hours to balance wear patterns.

Indoor settings demand precision, and cushion tyres deliver with a static load capacity of up to 18,000 lbs. Their wide contact patch distributes weight evenly, minimizing floor stress—critical for facilities with weight-sensitive mezzanines. Imagine threading a forklift through pallet racks: cushion tyres act like a ballet dancer’s slippers, offering nimble pivots. However, they’re less forgiving on cracked concrete; even a ¼-inch gap can destabilize loads. Transitional Note: For mixed environments, some models offer hybrid tyre materials, though compromises exist.
What are the load capacity ranges for IC cushion tyre forklifts?
IC cushion tyre forklifts handle 3,000–15,000 lbs, with heavy-duty models reaching 35,000 lbs for specialized logistics. Standard units (5,000–8,000 lbs) dominate retail warehouses, while high-capacity versions serve manufacturing. Key factors: tyre width, axle strength, and combustion engine torque (e.g., 55–100 HP).
Load capacity directly correlates with tyre size and reinforcement. A Hyster H50-70HD with 10-inch tyres supports 15,000 lbs but requires a 4-cylinder diesel engine for torque. Pro Tip: Overloading by 10% reduces tyre lifespan by half—stick to OEM limits. Real-world example: An Amazon fulfillment center uses 6,000-lb capacity Mitsubishi forklifts with 8-inch tyres for small-item stacking. Transitional Note: Always verify load center adjustments—a 24-inch center versus 36-inch can derate capacity by 25%.
| Model | Capacity (lbs) | Tyre Size (in) |
|---|---|---|
| Toyota 8FGCU25 | 5,000 | 8×4 |
| Hyster H50CT | 10,000 | 10×6 |
| Cat ET3000 | 15,000 | 12×8 |
What fuel options power IC cushion tyre forklifts?
IC cushion tyre forklifts primarily use propane, diesel, or gasoline. Propane dominates indoor use due to low emissions, while diesel suits high-torque outdoor/indoor hybrids. Gasoline models are cost-effective but less common in regulated industries. Pro Tip: Diesel engines last 30% longer but require frequent DPF filter cleaning in dusty settings.
Propane’s popularity stems from quick refueling (3–5 minutes) and cleaner combustion—emitting 80% fewer particulates than diesel. However, diesel variants like the Komatsu FD50T-17 deliver 20% more torque for heavy loads. Gasoline models, though rare, appeal to budget-focused operations but face rising ethanol-related corrosion issues. Did you know? A single propane tank typically lasts 6–8 hours, while diesel engines average 10–12 hours per tank. Transitional Note: Fuel choice impacts maintenance schedules; propane engines need 100-hour spark plug checks, diesels require 500-hour injector servicing.
How to maintain cushion tyres on IC forklifts?
Maintain cushion tyres through daily debris checks, monthly tread depth measurements, and bi-annual rotations. Use pH-neutral cleaners to prevent rubber degradation. Target tread depth: above 3/16 inch. Worn tyres increase energy consumption by 12–15% due to slippage.
Start by inspecting for embedded nails or glass—common in shipping hubs. A tread gauge costs under $20 and prevents surprises. Rotate tyres every 500 operational hours to balance wear; front tyres wear 3x faster than rears. For example, a Wal-Mart DC triages tyre wear by assigning forklifts to zones based on floor abrasiveness. Pro Tip: Apply silicone-based protectants quarterly to prevent rubber cracking. Transitional Note: Never ignore vibrations—they signal uneven wear or axle issues.
Cushion vs. Pneumatic Tyres in IC Forklifts: Key Differences?
Cushion tyres excel indoors with solid construction and compactness, while pneumatics tackle outdoor terrain using air-filled shock absorption. Cushion tyres last 2–3x longer on smooth surfaces but fail on uneven ground.
Cushion tyres reduce costs (no air pumps/flat repairs) but limit application flexibility. Pneumatic tyres, with 10–15 PSI adjustability, handle gravel but require weekly pressure checks. For instance, a construction supply yard uses pneumatics, while a pharmaceutical warehouse opts for cushion tyres. Transitional Note: Hybrid solutions exist but sacrifice 15% efficiency in both environments.
| Factor | Cushion Tyres | Pneumatic Tyres |
|---|---|---|
| Surface | Smooth indoor | Rough outdoor |
| Maintenance | Low | High |
| Cost | $200–$400/tyre | $400–$800/tyre |

FAQs
Brief outdoor transitions (under 10% of runtime) are acceptable, but prolonged use causes rapid tread wear and cracks. Always rinse tyres post-exposure to remove corrosive elements.
How often should I check tyre alignment?
Inspect alignment every 250 operating hours. Misalignment over 1/8 inch accelerates wear by 40% and strains drivetrains.
