Abstract

A truck-mounted forklift, also known as a piggyback forklift, TMFL (Truck-Mounted Forklift), or all-terrain forklift, is a compact, self-propelled forklift designed to attach securely to the rear of a delivery truck or trailer. It travels with the vehicle and detaches at the delivery site, allowing drivers to unload cargo without needing a separate forklift or loading dock. These units can be dismounted and ready to deliver loads in under 60 seconds.How a Truck-Mounted Forklift WorksThe forklift is secured to the rear of a truck or trailer using a pre-installed carrier system with hooks, chains, or latches. Once the delivery truck arrives at the destination, the forklift is dismounted from the carrier under its own power. After the delivery is complete, the forklift is driven back onto the truck and secured for transport.The design allows the forklift to be carried on almost any truck or trailer without taking up valuable load space on the truck bed itself.Key Features and Specificatio

How a Truck-Mounted Forklift Works

The forklift is secured to the rear of a truck or trailer using a pre-installed carrier system with hooks, chains, or latches. Once the delivery truck arrives at the destination, the forklift is dismounted from the carrier under its own power. After the delivery is complete, the forklift is driven back onto the truck and secured for transport.


The design allows the forklift to be carried on almost any truck or trailer without taking up valuable load space on the truck bed itself.

Hydrogen Powered Forklifts: The Complete Guide to Fuel Cell Technology in Material Handling

Hydrogen powered forklifts represent a growing alternative to traditional battery-electric and internal combustion lift trucks. Instead of storing energy in a heavy battery that requires hours to charge, these machines use hydrogen fuel cells to generate electricity on board, producing only water vapor as exhaust. As of 2024, approximately 50,000 hydrogen forklifts operate worldwide, with the majority in the United States [0†L37-L38]. Major logistics operators including Walmart, Amazon, and BMW have deployed hydrogen forklifts in their warehouses, and BMW plans to convert its entire intralogistics fleet of around 320 industrial trucks to hydrogen by 2031 [0†L10-L12][0†L23-L28].How Hydrogen Powered Forklifts WorkA hydrogen powered forklift uses a fuel cell instead of a battery to generate electricity. Hydrogen gas is stored in high-pressure tanks mounted on the forklift, typically at pressures of 350 bar (5,000 psi) or 700 bar (10,000 psi). The fuel cell combines hydrogen with oxygen fr
