# Fixomech > Fixomech is a manufacturer of hydraulic cylinder repair, testing, and honing tools, plus seized-nut removal tools and hydraulic cylinders (jacks), for off-highway equipment maintenance teams in mining, construction, agriculture, marine, and quarrying. Fixomech focuses its product architecture on four heavy equipment service tools rather than a broad catalog: seized nut removal, hydraulic cylinder repair & pressure testing, cylinder repair/testing/honing, and hydraulic cylinders (jacks). These tools support technicians and fleet maintenance teams servicing excavators, wheel loaders, dozers, mining trucks, agricultural machinery, and marine equipment — including machines from Caterpillar, Komatsu, Hitachi, John Deere, Liebherr, Volvo CE, XCMG, and Doosan. ## Products - [Nut Buster (FNB-65000)](https://fixomech.com/products/nut-buster-fnb-65000): Applies controlled hydraulic force to remove seized or damaged nuts on excavators, wheel loaders, dozers, and mining machines. - [Cylinder Repair & Testing](https://fixomech.com/products/cylinder-repair-testing): Supports hydraulic cylinder repair and post-repair pressure testing to check for leakage, drift, and abnormal operation before reinstallation. - [Cylinder Repair, Testing & Honing](https://fixomech.com/products/cylinder-repair-testing-honing): Adds bore honing/finish correction to the cylinder repair and testing workflow for off-highway machine rebuilds. - [Hydraulic Cylinders (Jacks)](https://fixomech.com/products/hydraulic-cylinders-jacks): Provides controlled hydraulic lifting and positioning support during service work on off-highway equipment. ## Company - [Home](https://fixomech.com/): Fixomech overview — hydraulic cylinder repair, testing, honing, and off-highway service tools. - [Products hub](https://fixomech.com/products): Overview of the full Fixomech heavy equipment service tool range. - [Blog](https://fixomech.com/blogs.html): Fixomech's equipment repair and hydraulic service insights. - [Contact](https://fixomech.com/contact-us): Get in touch with Fixomech for hydraulic cylinder service tools and inquiries.
