PRECISION EXCAVATOR ATTACHMENTS.
MADE IN POLAND.
Buckets, quick-couplers & attachments for excavators and loaders

European-made buckets, couplers and tools for 1–65 t excavators, and for heavier carriers on request. Built for contractors and dealers.
Many attachments in our catalog began as a custom solution for a customer who needed something that didn't exist.
Backed by EN 10204 3.1 inspection certificates.
WHAT ARE YOU WORKING ON?
FROM PROBLEM TO PRODUCT.
1. The Requirement
You encounter a site constraint or specific machine geometry. We define the operational parameters and load requirements together.
2. The Engineering
We engineer the solution for your machine and your application. We simulate stress loads, select materials (Hardox® 450/500), and prototype the attachment.
3. The Solution
The design goes into series production. OEM projects are treated as confidential and are not moved into the public catalog. Improvements that are not tied to one customer go into our standard products.

Pressure-vessel authorisations
The group holds UDT authorisations for the manufacture, modernisation and repair of pressure vessels, and the attachments division inherited its qualified welding procedures and material certificates.
Our lineageNine processes under our own roof
Nine processes in our own plant, across seven production steps: milling, turning, plasma and gas cutting, bending, rolling, welding, assembly, painting and quality assurance. Heat treatment, blasting and casting are done by partners. 3,000 m² of production floor.
Inside the plant6 engineers in our own design office
We build to your drawing, work from a sketch just as readily, or reverse engineer from a worn part.
