| 1. Automated low-lift pallet truck | Typical rated load: about 1.0–2.0 tonnes. Lifts a pallet just clear of the floor; designed mainly for horizontal transport. Travel speed and load rating depend on the model and operating conditions. | Regular pallet transfers between receiving, production, staging, and shipping areas; repeatable routes on mostly level floors. | Plan pedestrian crossings, turning areas, and load-stability controls. Use the truck’s obstacle detection alongside clearly marked routes and appropriate site traffic rules. | Low to medium. Usually one of the simpler options to deploy when routes and hand-off points are predictable. | Does not provide high-level storage or complex pallet placement. |
| 2. Automated walkie stacker | Typical rated load: about 0.8–1.6 tonnes. Lift heights commonly range from roughly 1.6–5 metres, subject to configuration and mast design. | Low- to medium-height rack storage, replenishment, and pallet moves in smaller facilities or areas with moderate throughput. | Assess load height, mast visibility, floor condition, and pedestrian exposure. Rack clearances and load placement need to be validated for the actual truck. | Low to medium. Can suit operations that need stacking without a larger counterbalanced truck. | Lower lift capacity and operating envelope than many ride-on warehouse trucks. |
| 3. Automated counterbalanced forklift | Typical rated load: about 1.0–3.5 tonnes. Common lift heights are approximately 3–6 metres; exact capacity decreases as load centre and lift height increase. | Mixed indoor tasks, dock transfers, floor-level pallet handling, and operations that need a versatile truck with front forks. | Check turning space, reversing and crossing points, dock edges, and mixed-traffic areas. Rated capacity must be checked against the load centre and lift height. | Medium to high. Cost rises with capacity, navigation requirements, and integration with warehouse systems. | Requires more manoeuvring space than many dedicated narrow-aisle solutions. |
| 4. Automated reach truck | Typical rated load: about 1.0–2.0 tonnes. Depending on the design, lift heights can be around 6–11 metres. Aisle needs vary with truck geometry and pallet dimensions. | High-bay pallet storage in selective-rack warehouses where efficient use of vertical space matters. | Verify rack tolerances, aisle clearances, floor flatness, and load stability at height. Establish safe separation from people and manual vehicles. | High. Typically requires more precise site preparation and rack-to-truck coordination than floor-level transport. | Best suited to defined storage aisles; less flexible for frequent work across open areas. |
| 5. Automated double-deep reach truck | Designed to place pallets two positions deep in compatible racking. Capacity and maximum lift height depend on the truck, load centre, and attachment configuration. | Warehouses seeking greater storage density than single-deep selective racking, with reasonably consistent pallet sizes and inventory flows. | Confirm visibility and accurate pallet positioning at both rack depths. Rack design, pallet condition, and load dimensions must match the truck’s operating limits. | High. The truck and compatible racking may require coordinated investment and detailed commissioning. | Access to rear pallet positions can be less direct, reducing selectivity compared with single-deep storage. |
| 6. Automated very-narrow-aisle turret truck | Designed for guided operation in narrow aisles and high-bay storage. Lift heights can reach roughly 10–15 metres on suitable configurations; load capacity and aisle width are model- and site-specific. | High-throughput facilities where land or floor area is constrained and storage density is a priority. | Requires carefully engineered aisle guidance, rack alignment, floor tolerances, and pedestrian exclusion or protection measures. Validate emergency access and recovery procedures. | Very high. Often involves substantial facility, rack, guidance, and systems-integration requirements. | High storage density, but comparatively limited flexibility if aisle layouts or operating processes change. |
| 7. Automated order-picking truck | Performance varies by design: some units carry a picking platform or operator, while others support goods-to-person workflows. Platform height, load capacity, and travel speed are configuration-specific. | Piece-picking operations that need to move pickers or order containers through defined warehouse routes. | For platforms carrying people, assess access, fall protection, emergency lowering, and the exact operating mode. Keep pedestrian interaction and pick-face access in the safety assessment. | Medium to very high. Cost depends strongly on whether the system carries a person, integrates with picking software, or supports automated goods-to-person handling. | Can improve movement between pick locations, but does not remove the need to design safe and efficient picking processes. |
