A truck-mounted forklift turns a delivery truck into its own loading dock. The unit rides on the back of the vehicle between stops, drops to the ground when the driver arrives, and unloads pallets at job sites, stores, and yards that have no dock and no forklift of their own. The category is also called a TMFL, an all-terrain forklift, or simply a Moffett, after Cecil Moffett, who invented the concept, and the name survives because Moffett units dominate the market. The convenience explains the demand: truck mounted forklift draws roughly 1,900 US searches a month at a cost per click around $5.52, moffett forklift about 4,400 searches at a CPC near $4.95, and moffett forklift training about 30 searches at a CPC above $10, all at keyword difficulty of zero per the DataForSEO snapshot behind this page. The safety picture is less convenient: three wheels, no counterweight, and a mounting operation at every stop. This guide covers what that means in practice. It sells no forklifts and no safety systems.
What a truck-mounted forklift is
A truck-mounted forklift is a powered industrial truck designed to be carried on, and operated from, a delivery vehicle. It has pneumatic tires and is intended for outdoor use on uneven ground, which is how it unloads at unimproved sites. Most are three-wheel machines, and unlike a conventional counterbalance truck they carry no counterweight: the truck body and its positioning provide what stability the design has. That single difference, plus the mount and dismount cycle repeated at every stop, is why the machine gets its own training category even though OSHA treats it as a powered industrial truck under 29 CFR 1910.178. The types of forklifts guide places it in context; the outdoor forklift safety guide covers the ground conditions it operates on.
Why stability is the core issue
Trainers state the risk plainly: truck-mounted forklifts may be more prone to tipping because they have only three wheels, and manufacturers engineer the geometry to resist rollover, but the classic tip triggers remain turning or braking too quickly and driving too fast on uneven ground. The missing counterweight changes the load math as well. Because the machine does not carry a counterbalance, the weight of the load sits further forward in the stability picture, and any attachment that adds weight or changes the center of gravity must carry the manufacturer’s explicit approval, with the capacity plate updated to match. Attachments that raise people, such as lift platforms, are not permitted on these trucks at all, because there is no counterbalance to support them, per the guidance published by Hard Hat Training. The forklift tipping guide explains the stability principles underneath all of this.
Mounting and dismounting
The mount and dismount cycle is the operation most other forklift programs never think about, and it is a trained skill. Provider course outlines treat it as a core competency: the practical test for a truck-mounted forklift includes mounting and dismounting a trailer, mounting, starting and stopping the truck, driving forward and reverse with braking, accurate steering, placing loads, judging fork-tip position at height, stacking and de-stacking, and parking, per the syllabus published by 2 Start Training. Around the mount points the routine is the same one the forklift mounting and dismounting guide describes for any truck, with the added rule that the unit is only lowered and raised on stable, level ground with the delivery vehicle secured, wheels chocked, and the surrounding area clear of people. Riders and helpers stay clear of the mount zone, and nobody stands under the unit while it is being raised or lowered onto the truck.
Load limits without a counterweight
With no counterweight, the rated capacity and the load chart are the entire stability program. Loads must stay centered, within the rated capacity, and as low as practical while traveling, and the operator judges every load against the machine’s rating rather than assuming the truck will handle what a counterbalance unit of similar size would. The approved-attachment rule is absolute: any attachment, from extended forks to swivel mounts, requires manufacturer approval and a revised capacity plate, and personnel platforms are out of bounds. The forklift load backrest guide and the forklift data plate guide cover the plates and load-placement fundamentals that apply to every class.
Pre-use checks
Truck-mounted forklifts need the same daily pre-operation inspection as any powered industrial truck, and provider checklists show how long the list is: lights and warning devices, steering, hydraulics and hydraulic controls, the mast, mast rollers, lift chains and pulleys, the back-rest extension, carriage plate, fork arms, tires and wheels, drive and braking, external condition, the operator seat and operating position, plus fuel checks covering oil, coolant, battery, belts, and the inching pedal on internal combustion units or electrolyte levels and connections on electric ones. The inspection checklist guide on this site is the base form to adapt for the extra mounting hardware and the terrain duty.
Training and certification
Because the machine is a powered industrial truck, OSHA 29 CFR 1910.178(l) training applies: classroom and practical instruction specific to the truck type and workplace, evaluation before solo operation, and refresher training with re-evaluation at least every three years, plus retraining after accidents, near misses, or observed unsafe operation. Operators must be at least 18. Provider programs reflect the extra skills involved: UK course structures run about five days for a novice, three for an experienced operator, one for a refresher, and two to three for a conversion from another truck type, with refresher intervals of three to five years recommended under the UK approved code, per 2 Start Training. US operators also face the general powered industrial truck rules on speed, clear view, horn use, and the load-upgrade rule on grades, all of which the OSHA regulations guide walks through. The training cost guide and the certification FAQ cover the program and the paperwork side.
Delivery-site hazards
The delivery environment adds exposures a warehouse never has: public areas, customer employees who are not trained around forklifts, tight maneuvering around parked vehicles, weather, and soft or sloping ground at the delivery point. Site rules that apply here mirror the guidance in the warehouse pedestrian safety guide and the safety rules guide: separate pedestrians from the machine, use spotters in congested or blind areas, sound the horn before moving, and never assume bystanders see the truck. The forklift transport guide covers the securement side for the delivery vehicle itself.
