What a machine dealer gets from us
Matched to your models
Tell us the brands and weight classes you sell. We match buckets and couplers to each model: pin sizes, coupler interface and bucket widths.
The coupler your machines use
We build to the common quick coupler interfaces, including the S-System, CW and MS, and to pin-on mounting.
One factory for your whole range
Digging, ditch cleaning and grading buckets, grabs and quick couplers come from our own factory, so one supplier covers the attachments for your whole range.
Design office on site
For a model we have not built for yet, our design office works from the machine data, a sketch or a sample.
Want to see what we already offer for a given machine? Attachments by make and model
Fleet standardisation: if your customers run several machine models, we can build the attachments to one coupler interface across the whole fleet. Send us the model list and the coupler you want to settle on, and we check each machine.
Do you run a rental fleet? Attachments for rental fleets
Ready for your pre-delivery
We paint the attachments in your machine brand's colour and mark them to your numbering scheme, so they arrive ready for your pre-delivery inspection.
Bucket and coupler can leave your yard on the machine, sold as one package with it.
Standards and paperwork
Our buckets and quick couplers are designed to EN 474-1. Our MS and S-System quick couplers are designed and built to EN 474-5 and ISO 13031.
The attachments are CE marked and made in line with the European directives, including the Machinery Directive.
Every product that carries the CE mark ships with its CE declaration of conformity. If you want, we agree the EN 10204 3.1 inspection certificate as a standing term of your supply: every delivery then carries it. By serial number we also send the test report and the manual, where one exists. Manuals come in English, German, French and Polish. Other EU languages are available on request.
Lead time, stock and delivery
Every offer names the dispatch week, so you can plan it against your machine deliveries.
No minimum order. A new machine dealer usually starts with a few test units, one of each of its most-requested models.
Depending on the item, we build to stock or to order. What we keep in stock for you is agreed with each distributor and machine dealer: finished attachments, subassemblies or parts, so the lead time stays short.
We quote ex works Ostrołęka, or delivered to your yard on request. We deliver to every EU country, Norway, Switzerland and the United Kingdom.
After the sale
Our attachments carry a 12-month warranty. You stay your customer's first contact: send us the serial number and photos, and we repair or replace from our factory.
Attachments you hold in stock: the 12-month warranty starts when the attachment is installed at your customer, not when we deliver it to you.
Spare and wear parts for every attachment we build come from our factory. For each bucket we send the exploded parts diagram by serial number.
We can train your sales and service staff on the range.
Your contact is Adrian Sieruta, Managing Director: adrian@sieruta.com. Our engineers work as one team for all partners.
