The Fiat Allis FB7B is a backhoe loader of the Fiat Allis brand, built in Italy. The register lists a water-cooled diesel engine and a crawler undercarriage. A backhoe loader carries a loader at the front for loading and levelling and a backhoe at the rear for digging trenches and pits; both are operated from the same seat.
The Fiat-Allis brand began in January 1974 from the construction equipment business of Allis-Chalmers as a joint venture with Fiat, which held 65 percent at first. It took the name Fiatallis in 1983, and in November 1985 Fiat bought the remaining stake. A crawler undercarriage means the weight is carried on tracks instead of tyres. That lowers ground pressure and the tendency to sink on soft ground, but makes moves between sites slower than on wheels. The register does not list a successor for the FB7B.
Fiat-Allis – other models: the collective page of construction machines FB-80 and FB7B (backhoe loaders), FD110 and FD30B (crawler dozers), FL175 and FL20 (wheel loaders) and SL40B and SL55B (skid-steer loaders)
This page gathers eight Fiat-Allis construction machines that the register could not assign to a named range: the backhoe loaders FB-80 and FB7B, the crawler dozers FD110 and FD30B, the wheel loaders FL175 and FL20, and the skid-steer loaders SL40B and SL55B. Fiat-Allis was formed in 1974 as a joint venture between Fiat and the American maker Allis-Chalmers, combining their construction equipment programmes until the 1990s, when the business passed to Fiat-Hitachi and later to New Holland's construction equipment division; accordingly both Fiat and New Holland engines are recorded for the models covered here.

The register lists here 8 versions with 27 to 250 kW, or 36 to 340 hp; all eight run on diesel.
With a line-up spanning backhoe loaders, crawler dozers, wheel loaders and skid-steer loaders, Fiat-Allis covered nearly the whole spectrum of earthmoving and civil engineering machinery through the 1970s to 1990s, competing in Europe and North America with makers such as Caterpillar, Case and JCB.
When buying used, what counts on these older Fiat-Allis machines is frame cracking and corrosion on load-bearing parts, the condition of hydraulic cylinders and hoses, and wear on the undercarriage or tyres; on the dozers, track rollers, track links and drive sprockets are added to the list. Because of the company's shifting history, spare parts are sometimes only available through specialist used-machinery dealers.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
