About KORDAX
The factory behind the attachments.
KORDAX is the attachments brand of Shanghai Mars Industrial Co., Ltd. We design and manufacture hydraulic breakers, quick couplers, grapples, demolition tools, compactors, augers and rippers for contractors, rental fleets and equipment dealers around the world.
Our story
From breaker workshop to full-line attachment maker
We started by building hydraulic breakers — the most demanding attachment on any excavator. Getting pistons, valves and housings right taught us the discipline of hardened steel, tight tolerances and honest testing.
Customers soon asked for the attachments that go with a breaker: quick couplers to switch tools, grapples to clear the rock, compactors to finish the trench. Today our range covers 30 product families for carriers from 0.8 to 50 tonnes, all built with the same process and the same test bench.
We sell factory-direct, which means you speak to the people who build your attachment — and you get engineering answers, drawings and test reports, not sales slogans.
