Start here

The attachments buyers in your market ask for first, sized for the DX245DM-7.

Which coupler is on your machine?

Pick the system on your machine and we put it in your enquiry. We check the bracket before we send the quote.

How to measure your coupler

Not sure which system it is? Three measurements tell us which bracket you need.

Measure the diameter of both pins.
Measure the distance between the pin centres.
Measure the width between the inside faces of the ears.

If the coupler has a make or type printed on it, send that too.

What the DX245DM-7 figures mean for its attachments

The main pump delivers up to 420 l/min at 343.23 bar. That is the pump output of the whole machine, not the flow an attachment gets.
It digs down to 4,880 mm. That is the deepest trench it can open.
Its maximum reach is 8,500 mm.
Its arm is 2,400 mm long.
Develon lists a bucket capacity of 1 m³.
For transport it measures 11,460 x 2,540 x 3,150 mm (length, width, height).
Engine power is 129 kW.

Before you order: check the interface

The weight class of the Develon DX245DM-7 sizes the attachment. It does not tell you the pin diameter, the pin spacing or the stick width, and those decide whether an attachment fits. Measure them on the machine, or send us the measurements of the bucket it runs today.

At this weight the choice is mostly about the material. A general purpose bucket suits soil and gravel, a reinforced bucket with thicker wear parts suits mixed ground and broken rock, and the quick coupler on the machine sets the bracket every attachment needs.

Heavy excavators dig rock, load trucks and work in quarries, so wear decides the bucket as much as capacity does. Rock and reinforced buckets carry thicker wear steel, teeth and side cutters, and the bucket is sized to the trucks it loads and to the density of the material.

Quick coupler brackets at this weight

In our model tables, the attachments listed for the Develon DX245DM-7 at its weight are built with these brackets. Each code opens the models that list it.

Measure the diameter of both bucket pins.
Measure the distance between the pin centres.
Measure the inside width between the stick ears.
If the machine runs a quick coupler, note its make and type.
