Sampierana has started teasing a new construction machine under the internal nickname “The Beast,” offering almost no official specifications but enough clues to suggest that the Italian manufacturer is preparing something outside its conventional compact excavator formula.
The company describes the project as a machine with an aggressive stance, unconventional design and performance intended to reach a higher level. No official model designation, engine specification, operating weight or launch date has been disclosed.
That deliberate lack of detail has already triggered speculation among followers. One of the most interesting guesses is “100STR,” while another commenter suggested “35TR.”
The first theory deserves particular attention because the Eurocomach product catalog now includes an excavator carrying exactly that designation.
Eurocomach 100STR Clue
Eurocomach, Sampierana’s earthmoving machinery brand, currently lists the 100STR, a roughly 10-ton Short Radius crawler excavator developed around a configuration that differs significantly from the company’s conventional machines.
According to Eurocomach, the 100STR has a transport weight of 100 quintals, or about 10 metric tons, and uses a fixed-base triple-piece boom. Unlike an excavator with the usual boom swing articulation at the chassis, the boom assembly is mounted rigidly to the machine structure.
That design is intended to increase structural rigidity, lifting capability and stability while retaining the positioning flexibility of a three-piece boom.
Eurocomach also specifically positions the machine for use with tilt-rotators, particularly in markets such as Sweden, Norway and Germany where these attachments have become common on highly equipped excavators. The company says the hydraulic and mechanical configuration was engineered to handle the additional weight and hydraulic requirements of multifunction tilt-rotators without compromising machine balance.
Those characteristics fit remarkably well with Sampierana’s description of a project featuring an unusual layout and performance ambitions above the normal level.
There is still an important distinction, however. Sampierana has not publicly stated that “The Beast” and the Eurocomach 100STR are the same machine. Until the manufacturer makes that connection itself, the identification remains a strong possibility rather than a confirmed model reveal.
Why the 100STR Is Different
The engineering philosophy behind the 100STR is arguably more interesting than the model designation itself.
Most compact and midi excavators are designed around versatility. Boom swing allows the operator to work close to walls or reposition the digging geometry without moving the entire upper structure.
Removing that articulation sacrifices one type of flexibility but eliminates another joint from the load path.
Eurocomach says the fixed mounting reduces the mechanical play associated with boom swing pins and gives the structure greater rigidity. Combined with the articulated three-piece boom, the arrangement is intended to provide both reach flexibility and improved load handling.
For operators using heavy tilt-rotators, grading attachments or other complex hydraulic tools, that tradeoff makes considerable sense.
It also points toward a broader change taking place in the European excavator market. Manufacturers are increasingly engineering machines around attachments rather than treating attachments as equipment added after the excavator has already been designed.
A tilt-rotator changes weight distribution, hydraulic demand and the loads applied to the boom and stick. Designing those requirements into the excavator from the beginning can produce a much better working package than simply adding the attachment later.
100STR vs 100TR
The 100STR would also give Eurocomach two distinctly different approaches around the 10-ton class.
The existing 100TR has a transport weight of approximately 10.08 metric tons and uses an articulated triple boom. Eurocomach positions it as a versatile midi excavator for intensive excavation and loading work. Its published engine output is 53.7 kW.
The 100STR takes that general size class in a more specialized direction.
Its Short Radius configuration, fixed boom base and explicit compatibility with tilt-rotators suggest greater emphasis on lifting, attachment work and operation in space-constrained urban environments.
That would explain why Sampierana might choose to market such a machine differently rather than presenting it as another incremental addition to the Eurocomach excavator lineup.
What “The Beast” Could Signal
My view is that the nickname is probably more significant than the usual social media teaser language.
Sampierana already manufactures machines covering the mainstream compact and midi excavator categories. Creating a deliberately aggressive teaser around another conventional excavator would offer limited value unless the underlying machine introduces a noticeably different layout or capability.
The 100STR fits that logic.
Its design is not radical in the sense of introducing an entirely new excavator architecture, but the decision to combine Short Radius packaging, a rigid boom mounting, a three-piece boom and tilt-rotator optimization represents a fairly focused engineering concept.
That could be particularly attractive in Northern and Central Europe, where contractors often expect one excavator to perform digging, grading, lifting and material-handling duties using multiple hydraulic attachments.
If “The Beast” does turn out to be the 100STR, its real selling point will probably not be maximum horsepower. The more important numbers will be lifting capacity, hydraulic flow, stability with heavy attachments and usable working envelope.
Those are the specifications worth watching when Sampierana releases the complete technical sheet.
About Sampierana Brand
Sampierana traces its origins to 1950, when Aleardo Para founded a small metalworking workshop in Italy. The company later expanded into earthmoving machinery, beginning production of mini excavators and other compact machines in 1993. Today Sampierana says it has more than 250 employees and collaborators.
Its main headquarters at San Piero in Bagno has expanded to more than 80,000 square meters. The company also operates a Modena location with more than 12,000 square meters of warehouse space, while a new Cesena production plant opened in June 2023 to expand production of excavators, compact loaders and electric machines up to the 2-ton category.
Sampierana produces construction equipment through the Eurocomach brand while also manufacturing undercarriages and replacement components. It has been an authorized Berco dealer for more than 40 years and introduced its own Sampierana-branded undercarriage component line in 2007.
CNH Industrial agreed to acquire Sampierana in 2021 in a transaction valued at €101.8 million, initially purchasing 90% of the company with a mechanism designed to obtain full control over the following four years. Sampierana had exceeded €100 million in annual revenue in 2020 before the acquisition agreement.
For now, Sampierana is keeping “The Beast” behind the curtain. But with the 100STR already appearing in the Eurocomach lineup, there is now considerably more substance behind the speculation than the teaser initially suggested.
