What the HMK 390 LC LR figures mean for its attachments

- It digs down to 11,870 mm. That is the deepest trench it can open.
- Its maximum reach is 16,870 mm.
- It dumps at up to 12,680 mm, so a truck or skip side has to sit below that height.
- Its arm is 6,000 mm long.
- Hidromek lists a bucket capacity of 1 m³.
- Hidromek gives a lifting capacity of 7,150 kg. Check a heavy grab or hammer, plus its load, against the full load chart.

- Engine power is 210 kW.

Before you order: check the interface
The weight class of the Hidromek HMK 390 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.
