At TopTrack, quality and reliability define every crawler crane undercarriage part we manufacture. Based in Qingdao, we are an experienced manufacturer and exporter serving global clients, with our products shipped to over 30 countries and regions worldwide.

We fully understand that crawler crane owners and dealers need robust, well-fitting spare parts to cut costly downtime on construction sites. Our full product portfolio covers track shoes, bottom rollers, carrier rollers, idlers and drive sprockets. Our parts fit roughly 97% of crawler crane brands and models across the globe, including Kobelco, Liebherr, Link-Belt, Sany, Manitowoc and many more. We also provide flexible custom services, including custom color painting, logo marking, and custom-made components for rare or modified crane models.

All our spare parts meet OEM standards for direct installation with no extra machining required. We carefully select premium alloy steel raw materials and match different steel grades according to your crane tonnage and working conditions. Every component undergoes casting or forging, plus quenching and tempering double heat treatment. This process optimizes hardness and impact toughness so our parts outlast standard aftermarket alternatives.

Our production follows ISO9001 quality management standards. We carry out rigorous inspections at every production stage, starting from raw material checks all the way to final packaging. Before shipment, we can supply inspection photos, videos and formal quality test reports. We back our undercarriage parts with a 2500 working-hour warranty, and our after-sales team stands ready to quickly resolve any fitting or installation questions you may have.
