Explore our most popular undercarriage components — compatible with leading excavator brands and trusted by Czech contractors, rental companies and dealers.
Czechia is one of Central Europe's most dynamic construction and industrial markets. Understanding the local landscape helps us serve Czech buyers with precision and speed.
The Czech construction industry has seen consistent growth, driven by EU-funded infrastructure programmes, motorway expansions (D1, D35, D48), urban regeneration projects in Prague, Brno and Ostrava, and a surge in logistics park developments. Excavators are the backbone of all these projects, creating steady demand for reliable undercarriage replacement parts.
Czechia has active limestone, sand, gravel and coal extraction operations — particularly in the Ústí nad Labem, Karlovarský and Moravian regions. Heavy excavators operating in these abrasive environments demand high-cycle undercarriage components with superior wear resistance, making premium track rollers, sprockets and idlers essential consumables.
The Czech equipment rental market is expanding rapidly, with companies like Cramo, Ramirent and dozens of local operators maintaining large fleets of Komatsu, Caterpillar, Hitachi, Kobelco and Doosan excavators. Fleet managers require cost-effective OEM-quality aftermarket undercarriage parts to reduce maintenance costs and maximise machine uptime.
Hesen's factory-direct supply model, strict quality standards and global logistics network make us the preferred partner for excavator undercarriage parts in the Czechia market.
No middlemen. Direct supply from our Fujian manufacturing base means Czech buyers enjoy the most competitive pricing on track rollers, idlers, sprockets and track links.
All parts are manufactured to OEM dimensional standards using high-strength alloy steels, precision CNC machining and heat-treatment processes that match or exceed original equipment specifications.
With established sea freight routes to Hamburg and Rotterdam, plus air freight options, we ensure Czech importers and dealers receive orders quickly — minimising costly machine downtime on job sites.
Our product catalogue covers 200+ excavator models including Komatsu, Caterpillar, Hitachi, Kobelco, Doosan, Volvo and Liebherr — all widely used across Czech construction and mining fleets.
Our factory's main products include: track roller (bottom roller), carrier roller (top roller), sprocket, idler, track link assembly, track shoe, bushing & pin, bucket teeth, high-strength bolts and nuts.

Several macro trends are reshaping the Czech heavy equipment aftermarket and accelerating demand for quality excavator undercarriage components.
The Czech Republic is one of the largest beneficiaries of EU Cohesion and Structural Funds in the 2021–2027 programming period. Billions of euros are being channelled into road construction, rail upgrades, flood protection and urban infrastructure — all requiring extensive excavator deployment and a continuous supply of replacement undercarriage parts.
Czech fleet operators are increasingly adopting a total cost of ownership (TCO) approach, choosing high-quality aftermarket parts over expensive OEM replacements. Premium Chinese manufacturers like Hesen offer OEM-equivalent quality at 30–50% lower cost, making them a natural fit for cost-conscious Czech contractors and dealers.
Advanced CNC machining, automated heat treatment and real-time quality inspection systems at Hesen's factory ensure consistent dimensional accuracy and metallurgical properties — meeting the high technical standards expected by Czech and European equipment operators.
Czech environmental regulations and green building initiatives are pushing contractors to extend the working life of existing excavators rather than purchasing new machines. This significantly increases the frequency of undercarriage replacement cycles and boosts demand for track rollers, idlers, sprockets and track shoes.
Czech machinery dealers and independent workshops are increasingly sourcing parts online via B2B platforms and direct manufacturer websites. Hesen's digital catalogue, fast quotation system and multilingual support make it easy for Czech buyers to identify, order and receive the exact undercarriage parts they need.
The Czech Republic has become a major European logistics hub, with massive warehouse and industrial park construction projects around Prague, Brno, Pilsen and Ostrava. These large-scale earthmoving projects run fleets of 20–50+ excavators, generating bulk demand for undercarriage consumables on a regular replacement schedule.
From Prague's metro expansion to Moravian quarries, Hesen undercarriage parts are engineered for the specific demands of Czech job sites.
Projects like the D35 Brno–Olomouc corridor and D48 Frýdek-Místek bypass deploy dozens of 20–30 tonne excavators in continuous operation. Track rollers and sprockets on these machines require replacement every 2,000–4,000 hours, creating a predictable and recurring demand for aftermarket undercarriage parts.
Urban excavation for metro tunnels, underground parking, utility trenching and building foundations in Prague and Brno requires compact and mid-size excavators. Komatsu PC30–PC130 and Hitachi ZX series machines operating in these environments need frequent undercarriage servicing due to hard ground and confined space manoeuvring.
Limestone and granite quarries in the Bohemian and Moravian regions operate large Caterpillar 320–390 and Komatsu PC400–PC800 excavators in highly abrasive conditions. These applications demand premium grade track shoes, hardened sprockets and sealed track rollers to withstand extreme wear rates.
Following major flooding events on the Elbe, Oder and Morava rivers, the Czech government has invested heavily in flood defence infrastructure. Long-reach excavators working in wet, muddy riverbank conditions place exceptional demands on undercarriage sealing systems and track link assemblies.
The Czech Republic hosts over 350 industrial zones. Greenfield logistics park developments for Amazon, DHL and local operators near Pilsen, Liberec and Pardubice involve extensive mass earthmoving, where excavator fleets operate around the clock and undercarriage wear rates are maximised.
Rural Czech regions rely on small and medium excavators for drainage channel maintenance, pond construction and forestry road building. Mini excavators (Komatsu PC30, Kubota, Yanmar) operating in these soft ground conditions require compact undercarriage parts that balance cost and durability for lower-intensity applications.
Our factory's main products include: track roller (bottom roller), carrier roller (top roller), sprocket, idler, track link assembly, track shoe, bushing & pin, bucket teeth, high-strength bolts and nuts.
