| Rated Load Capacity | 3,500 kg at a commonly specified 500 mm load center | Capacity decreases when the load center is longer, the mast is raised higher, or the load is uneven. | Select a truck with a residual capacity above the heaviest planned load, including pallets, attachments, and load-center changes. |
| Load Center | 500 mm is a common rating point; 600 mm or more may apply to long or irregular loads. | A longer load center increases the overturning moment and reduces safe lifting capacity. | Use the manufacturer’s capacity chart for the actual load dimensions rather than relying only on the nominal 3.5t rating. |
| Lift Height | Common mast configurations provide approximately 3,000–6,000 mm of lift; higher options are available. | The required lift height depends on rack height, clearances, ceiling height, and load stability. | Choose a mast that reaches the top storage level while maintaining sufficient overhead clearance and residual capacity. |
| Mast Configuration | Two-stage, full-free-lift two-stage, and three-stage masts are commonly available. | Full free lift helps prevent the forks or load from rising into low ceilings before the mast extends. | Use full free lift for containers, low doorways, and low-ceiling areas; use a three-stage mast for high racks. |
| Fork Length | Typical fork lengths are approximately 1,070–1,220 mm, with other sizes available. | Forks that are too short may not support the load adequately; forks that are too long can create clearance and handling problems. | Match fork length to pallet depth and load geometry, while keeping the load properly supported and balanced. |
| Aisle Width | Many counterbalance trucks require roughly 3,900–4,500 mm for a 90-degree pallet-turning aisle, depending on configuration. | Truck dimensions, load size, steering angle, and operator skill all affect the minimum safe aisle width. | Measure the narrowest aisle with the largest pallet and compare it with the truck’s published turning-radius and aisle data. |
| Turning Radius | Approximately 2,400–2,800 mm is a common range for many 3.5t counterbalance configurations. | A smaller turning radius improves maneuverability in congested warehouses but does not replace adequate clearance. | Prioritize compact dimensions and responsive steering for indoor storage areas and tight loading zones. |
| Power Source | Electric, diesel, and liquefied petroleum gas configurations are commonly used in this capacity class. | Power choice affects emissions, noise, refueling or charging time, operating cost, and suitability for indoor use. | Choose electric for clean, quiet indoor work; diesel for demanding outdoor applications; LPG where fast refueling and mixed-use flexibility are important. |
| Battery and Charging | Lead-acid and lithium-ion battery systems are widely used; charging requirements vary by voltage, capacity, and duty cycle. | Battery capacity, charging access, ventilation, and shift pattern determine equipment availability. | For multi-shift operations, evaluate opportunity charging, spare batteries, charging-room requirements, and total energy cost. |
| Tire Type | Cushion tires are suited to smooth floors; pneumatic or solid pneumatic tires are better for rougher surfaces. | Tires influence traction, vibration, ground clearance, turning behavior, and indoor floor protection. | Use cushion tires on smooth warehouse floors and pneumatic-style tires where outdoor surfaces, ramps, or uneven ground are common. |
| Ground Clearance and Gradeability | Ground clearance and maximum gradeability vary by tire, drivetrain, load, and operating surface. | Ramps, dock plates, yard surfaces, and wet conditions can reduce traction and climbing performance. | Confirm performance using the actual loaded weight, ramp gradient, surface condition, and travel direction. |
| Attachment Compatibility | Side shifters, fork positioners, clamps, rotators, and other attachments are commonly available. | Attachments add weight and move the effective load center, which can reduce rated capacity. | Specify the attachment, maximum load, and load dimensions together, then verify the revised capacity plate. |
| Operator Visibility and Safety | Important features include an overhead guard, clear mast visibility, seat belt, lights, horn, reversing alarm, and mirrors or camera systems. | Visibility and warning systems help reduce collision, pedestrian, and falling-load risks. | Select safety equipment according to traffic density, visibility limitations, site rules, and applicable local regulations. |
| Ergonomics | Adjustable seating, low-vibration controls, accessible visibility, and easy-entry steps are common evaluation points. | Better ergonomics can reduce operator fatigue and support consistent productivity during long shifts. | Conduct an operator trial during representative loading, travel, reversing, and stacking tasks. |
| Maintenance and Service Access | Daily checks commonly include forks, chains, mast, tires, fluids, battery or fuel system, brakes, steering, and safety devices. | Accessible service points can reduce inspection time and help prevent avoidable downtime. | Compare inspection access, service intervals, technician availability, spare-parts support, and expected downtime. |
| Operating Environment | Indoor warehouses, outdoor yards, cold rooms, dusty areas, wet zones, and hazardous locations have different equipment requirements. | Temperature, ventilation, dust, moisture, and surface conditions affect safety, reliability, and power-system suitability. | Document the site conditions before selection and confirm that the truck configuration is approved for the intended environment. |
| Compliance and Training | Operator training, pre-use inspections, capacity marking, and workplace risk controls are fundamental requirements. | Safe operation depends on both suitable equipment and competent, authorized operators. | Confirm local legal requirements, provide documented training, and maintain a routine inspection program. |
