Engineered for high load capacities and long service life in urban excavation sites.
London is currently experiencing one of the most intensive periods of infrastructure remodeling in its history. From the massive tunnels of the Thames Tideway Project and the high-speed rail links of HS2, to extensive urban regeneration schemes across Greenwich Peninsula and the Docklands, tracked excavators are the workhorses driving this evolution. However, operating heavy machinery in the London market presents unique geological and regulatory challenges that contractors must address.
The ground beneath London is dominated by the infamous "London Clay"—a highly cohesive, stiff soil that becomes extremely sticky when wet and rock-hard when dry. For crawler excavators, this soil profile places immense stress on undercarriage components. Sticky clay adheres to track shoes, packing into the chain links and rollers, which increases track tension and accelerates wear on sprockets and bushings. Standard undercarriage parts quickly fail under these conditions, leading to costly downtime. This is why London contractors demand specialized, high-durability track shoe systems and heavy-duty rollers designed to shed debris and resist structural fatigue.
Operating in Greater London requires strict adherence to the Non-Road Mobile Machinery (NRMM) Low Emission Zone regulations. While engines must meet Stage V emissions standards, site managers also prioritize mechanical efficiency. A worn undercarriage increases rolling resistance, forcing the excavator engine to work harder and consume more fuel, thereby increasing carbon emissions. High-quality track links, sprockets, and rollers from reliable factories ensure that the machine operates at peak mechanical efficiency, minimizing fuel burn and aligning with London's net-zero construction goals.

In the UK construction sector, hourly downtime costs for a 20-ton excavator can exceed £500. Sourcing reliable track shoes and rollers directly from an experienced factory like Hesen guarantees OEM quality and minimizes unexpected site failures.
Quanzhou Hesen Machinery Industry Co.,Ltd, located in Fujian Province, is a highly experienced manufacturer founded in 1990. We are a factory specialized in high-strength bolts and nuts, bucket teeth, pins & bushings, and excavator and bulldozer undercarriage parts. We also maintain a large-scale warehouse to store parts and provide rapid delivery for our global customers. By combining professional design, R&D, advanced manufacturing, and sales, our products have successfully captured major markets both at home and abroad.
Our factory processes leverage state-of-the-art forging lines, automated machining centers, and strict quality control protocols to ensure every track shoe, roller, and sprocket meets or exceeds OEM standards.
Learn More About UsWhen selecting excavator track shoes (also known as crawler shoes or track pads) for London's demanding construction environments, material science and heat treatment are the two most critical factors. Track shoes must support the weight of the excavator while providing traction and resisting wear from abrasive soils.
At our factory, we use high-grade alloy steels (such as 25MnB or 23MnB) for track shoe production. These boron-alloyed steels offer exceptional hardenability. Through our advanced continuous hardening and tempering process, we achieve a surface hardness of HRC 42-49 and a core toughness that prevents cracking under heavy impact. This ensures that when an excavator is navigating rubble on a demolition site in central London, the track shoes will not bend or fracture.
The track link assembly is the heart of the crawler system. The pins and bushings act as the hinge joints, bearing massive rotational forces. We manufacture our track pins using 40Cr steel, induction hardened to a depth of 3-5mm with a surface hardness of HRC 52-58. The track bushings are made from 20CrMnTi, carburized and quenched to resist internal wear from abrasive soil entry. Our sealed and lubricated track (SALT) chains are highly recommended for London contractors to significantly reduce internal pin and bushing wear, extending overall track life by up to 50%.
To ensure uniform track wear, the alignment of bottom rollers (track rollers) and top rollers (carrier rollers) must be precise. Our rollers feature heavy-duty dual-cone seals and high-quality bronze bushings, pre-filled with synthetic oil to run cool in demanding conditions. Our drive sprockets are forged and induction-hardened on the tooth profile to prevent premature chain slippage and track jumping.
Explore our extensive range of high-performance replacement parts engineered for global excavator brands.

Our factory provides seamless logistical connections to the UK. Standard container shipments land at the Port of London (Tilbury/Gateway), while urgent replacement parts can be dispatched via air freight to London Heathrow (LHR) within days, backed by our extensive warehouse inventory.
For plant hire companies operating in London, managing operational costs is a primary objective. Undercarriage wear accounts for up to 50% of an excavator's maintenance budget. Sourcing directly from an established Chinese manufacturer like Hesen Machinery allows companies to optimize their supply chain and reduce parts cost without sacrificing reliability.
Hesen Machinery provides a direct factory-to-site supply channel. By bypassing intermediate distributors, we offer substantial cost savings to UK plant hire companies, contractor groups, and local equipment dealers. Our technical support team assists in selecting the precise steel grades and specifications required for the unique soil conditions and machine models active on your job sites.
