By machine class

Attachments for a 10 to 20 tonne excavator

The standard site excavator.
Here the question is no longer “will it fit” but “does it produce enough” — and the constraint moves towards transport.

Other names for this class: tracked excavator, earthmoving excavator, digger, 14 t excavator, 20 tonne excavator, site excavator, wheeled excavator of the same tonnage.

The essentials

Common coupler: Hydraulic, S or CW
Auxiliary line: Standard
Constraint no. 1: Transport
Strength: Output

Five silhouettes of excavators arranged from the smallest to the largest.
Under each one, its tonnage range, the constraint that governs the choice
of an attachment and the strength of the class. The class dealt with by this
page is picked out in colour. — Your class is the fourth. The machine can do almost everything:
what limits it is transport — the width, height and mass of the whole once the tool is fitted.
The relative sizes are indicative.

A tracked excavator loading a lorry on an earthworks site, its bucket above the body. — It is the most widespread class, and that is no accident:
it loads a lorry without having to move it.

01 The class

What this class allows, and what it rules out

It is the production machine.
Housing-estate earthworks, roads and utilities, cleaning out a length of ditch, ordinary demolition, loading:
it does everything, and it does it fast.
Almost no family of attachments is closed to it.

Hydraulic flow and stability are no longer the questions. What limits it is what can be brought onto the site and taken away again:
beyond a certain machine-plus-tool weight, transport tips into another category, with its authorisations and its costs.

It is the class where a quick coupler pays for itself fastest. A machine of this tonnage costs a lot per hour.
Every tool change made by hand, by two people, with pins to knock out, is paid for in hours of downtime — and several are made every week. See the hitching technologies.

02 What fits

The tools that go on this class

On-site recycling, at last at full capacity A screening bucket from a large range, as recorded, covers 17 to 24 t, another 23 to 40 t.
It is from here on that on-site screening becomes worthwhile.
Sorting and heavy handling Clamshell grapple bucket recorded at 2 to 50 t, forestry timber grapple 2 to 35 t.
See the grapples and the sorting grabs.
Ripping and demolition A ripping tooth recorded goes up to 60 t. Breakers, grabs, crusher, crusher bucket :
the whole family is available, in useful sizes.
Production earthmoving Buckets of great width, tilting ditching bucket, skeleton bucket recorded at 1 to 50 t.

Beware of “mini” ranges on this class. One rotary mulcher recorded stops at 15 t, a pruning saw and a saw trimmer at 8 t.
Fitting an undersized tool on a big machine does not make it faster:
it destroys it.

03 Check

What is checked before buying

The system and the exact size of coupler Type S, CW, Klac, Morin, or direct pins. These systems are not interchangeable, and the size is read down the column, never across the row. See the couplers.
The total machine-plus-tool weight, for transport It is the constraint specific to this class.
It is checked before the order, not on the day of delivery.
The flow available for a tool with a continuous function A screener or a crusher turns without interruption. See the 7 criteria.
Compatibility with the existing fleet If you already have several machines, choosing the same coupler family allows the tools to be shared.
It is the easiest saving to make, and the most often forgotten.

Have your machine checked.

Give us the make, the model and the coupler system.
If you have several machines, say so:
the right choice is not always the one that suits a single one of them.
