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

- 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.

- The main pump delivers up to 752 l/min at 324 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- It digs down to 14,210 mm. That is the deepest trench it can open.
- Its maximum reach is 19,870 mm.
- It dumps at up to 14,760 mm, so a truck or skip side has to sit below that height.

Before you order: check the interface
The weight class of the Hidromek HMK 520 LC LR 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.
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.
