A small truck-mounted forklift (often called a "piggyback" forklift) is a compact, self-loading forklift that attaches to the rear of a delivery truck or trailer. It travels with the vehicle and detaches at the delivery site, allowing drivers to unload heavy cargo without needing a separate forklift or loading dock .
These machines are the ideal solution for "last-mile" logistics, especially when delivering to construction sites, farms, residential areas, or other locations where the customer does not have unloading equipment .
Why "Small" Matters: Compact Dimensions
The defining characteristic of a "small" truck-mounted forklift is its ability to fit onto a standard truck without exceeding legal road limits or taking up valuable cargo space.
Key Compact Design Features:
Low Collapsed Height: The mast folds down to a compact height (often 70" to 96") to fit under truck roofs and through low-clearance doorways .
Minimal Overhang: The unit does not stick out excessively beyond the truck's rear. The Moffett M4 45.3P has an overhang of just 52 inches .
Low Dead Weight: The forklift itself is lightweight to maximize the payload of the carrier vehicle. The Palfinger FLM 25 has a dead weight starting from just 1,870 kg .

Critical Features for Small Spaces
When choosing a model for tight delivery areas, look beyond just the weight and size. These specific features significantly enhance maneuverability:
4-Way Steering: This is a game-changer for long loads (pipes, lumber). The wheels can rotate 90 degrees, allowing the forklift to drive sideways. This makes it possible to navigate through narrow passageways or place long goods directly against walls .
Foldable Wheel Arms: This feature allows the forklift to be mounted on vehicles with strict overhang limits or "Euro hooks," preventing the unit from extending too far behind the truck .
Ground Assist / Remote Control: Some models (like the Palfinger FLM) allow the operator to mount or dismount the forklift while standing safely on the ground, which is a huge advantage when maneuvering in tight truck bays or slippery conditions .
Applications for Small Truck-Mounted Forklifts
These machines are essential for industries where the delivery point is difficult to access:
Building Supply & Roofing: Delivering lumber, shingles, and drywall directly to scaffolding or second-story levels.
Landscaping & Agriculture: Transporting sod, pavers, and feed across soft, muddy fields without damaging the turf or getting stuck .
Construction: Unloading heavy steel beams, concrete blocks, or windows at sites without cranes or ramps.
Waste & Recycling: Handling large bins and bales of scrap metal or paper in cramped industrial yards.
HVAC & Windows: Placing bulky items directly into loading zones with millimeter precision.
Installation and Mounting Options
How the forklift attaches to the truck affects legality and ease of use:
Standard ISO Hooks: Most common method; slides onto rails bolted to the truck chassis.
Undercounter / Box Mount: The forklift sits in a custom-built metal box under the truck body, offering the lowest center of gravity and safest road handling .
Foldable/Top Mount: Mounts on the top of the chassis; best for vehicles where rear overhang is strictly regulated by law .
The Bottom Line: Is a Small Truck-Mounted Forklift Right for You?
If your delivery routes frequently involve customers with no loading dock (construction sites, farms, residential homes) and you struggle with tight alleyways or soft ground, a small truck-mounted forklift is the ultimate productivity tool.
The Trade-off: You lose a bit of cargo space for the mounting equipment.
The Payoff: You eliminate the need for a second vehicle, waiting for a third-party crane, or manual unloading labor. For businesses like building supply, roofing, and landscaping, this machine often pays for itself within months by converting "difficult deliveries" into profitable revenue.
