Attachments for a 5 to 10 tonne excavator
The pivotal class.
Enough power for demolition and recycling, still
compact enough for an urban site — and that is where the hydraulic coupler
stops being a luxury.
Other names for this class: midi-excavator, midi digger, compact excavator, 8 tonne excavator, 8 tonne digger, 6 t excavator, intermediate excavator, 10 tonne excavator.

What this class allows, and what it rules out
It is the first class that does real heavy work without becoming a logistical
problem.
It still travels on an ordinary low-loader, it gets onto
a city-centre site, and it has the flow needed for a breaker or
a grab.
It is also the threshold of the hydraulic coupler. One model recorded
covers 4 to 60 t:
from this class on, changing tools without
getting out of the cab becomes an ordinary choice, not a convenience option.
The constraint that decides here is the number of hydraulic
functions. A hydraulic coupler uses up one function.
A rotating
grab uses up two.
A tiltrotator more still.
The machine you
have does not necessarily have enough lines for the tool you are aiming at, and that does not
show on a sales data sheet.
The tools that go on this class
-
The breaker, fully
One model recorded covers 4 to 7 t, and the higher ranges
take over up to the top of the class.
See the hydraulic breaker. - Selective demolition Demolition grabs, concrete crusher, shear, and the crusher bucket, which finds here its first useful sizes.
-
The top of the mini ranges
Screening bucket mini up to
8 t, mixer up to
8 t, pruning saw up to
8 t, saw trimmer up to 8 t.
Above 8 t, these families change range. - Sorting and road work Grapples, sorting grabs, kerb grab, asphalt disc, hydraulic drum cutter.
What does not fit yet: the
screening bucket from the large range, of which one
model recorded starts at 17 t.
On this class, it is the mini
range that is needed, and it does not give the same output.
What is checked before buying
- How many hydraulic functions are really available And how many are left once the coupler is fed. See the 7 criteria.
-
The flow and the pressure, at working speed
A badly fed breaker does not break:
it strikes without effect, and it wears out. -
The type and size of coupler
An S type coupler recorded covers 1 to 90 t in successive
sizes:
it is the size that counts, not the family. See the couplers. -
The operating weight, arm extended
A crusher bucket or a screener work loaded.
It is that weight that governs the sizing, not the catalogue one.
Have your machine checked.
Give us the make, the model, and above all the number of auxiliary lines
installed.
On this class, it is that piece of information that opens or closes
half the catalogue.
