09 Frequently asked questions

What we get asked most.

Can't find your answer? Call us and speak to a technician, not an answering machine.

What areas do you cover?

We are in O Barco de Valdeorras (Ourense) and ship daily throughout Spain and to international customers, especially in Portugal.

Are you official distributors for the brands?

Yes. We work directly with each manufacturer and, in Rammer's case, we have been direct importers for Spain since 2021.

How do I choose the right hammer for my excavator?

It depends on the weight of the machine, the hydraulic flow and pressure and the type of rock. Tell us your equipment and the application and we'll recommend the model and the attachment.

Do you have spare parts and after-sales service?

Yes. We keep stock of spare parts and consumables for the brands we distribute and provide technical support before, during and after the sale.

Do you install extraction systems in any industrial building?

Each installation is custom-designed after a study at the quarry or warehouse itself: flow rates, emission points, filtration and applicable regulations.
