The weight class of the Mecalac 12MRX 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.
Quick coupler brackets at this weight
In our model tables, the attachments listed for the Mecalac 12MRX at its weight are built with these brackets. Each code opens the models that list it.
Brackets we build attachments with in this weight range. Not a confirmed fit.
- 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.

What the 12MRX figures mean for its attachments
- Its auxiliary circuit is rated at 157 l/min and 300 bar. A breaker, auger, tilt rotator or other hydraulic tool states the oil flow it needs, so choose one whose range includes this figure.
- The main pump delivers up to 157 l/min at 300 bar. That is the pump output of the whole machine, not the flow an attachment gets.
- Mecalac lists this quick coupler for it: CONNECT hydraulic quick coupler. The bracket on every attachment has to match the coupler.
- It digs down to 4,100 mm. That is the deepest trench it can open.
- Its maximum reach is 7,125 mm.
- It dumps at up to 4,077 mm, so a truck or skip side has to sit below that height.
- Its arm is 2,210 mm long.
- Mecalac lists buckets from 350 to 1,200 mm wide for this machine.Our sizes in that range: DB - heavy duty digging bucket (DB-120); SDB - heavy duty skeleton DB bucket (SDB-120); DBF - flat-top digging bucket for quick coupler (DBF-120); RDBF - flat-top skeleton DBF bucket on rods (RDBF-120); CB - heavy duty hydraulic clamp bucket (CBR-120)
- Mecalac lists bucket capacities from 0.15 to 0.63 m³.
- Bucket breakout force is 59.5 kN and arm crowd force 32.9 kN. That is the force a bucket or ripper works with at the tooth.
- Its tail swing radius is 1,385 mm, which matters beside a wall or in a live traffic lane.
- Its transport length is 4,619 mm.
- Its transport width is 2,397 mm.
- Engine power is 85 kW.
