This heavy-duty track guard is a critical undercarriage protective casting part independently produced by Shandong Hengji Group Co., Ltd., perfectly matched for Shantui SD32 and SD320 320HP crawler bulldozers, widely used in open-pit mines, rock quarries and heavy earthmoving construction sites.
We adopt high-toughness alloy cast steel as raw blank, one-time integral casting forming without splicing welding, which avoids cracking risks under severe impact. The full production process includes precision casting, rough grinding, overall stress relief annealing, magnetic particle non-destructive flaw detection, shot blasting rust removal and anti-corrosion yellow paint spraying. The thickened arc curved structure enhances bending resistance and impact resistance; after annealing treatment, internal casting stress is fully released, so it will not crack or deform under long-term rock collision and bumpy road conditions.
Installed on both sides of the track frame outside track rollers, this track guard acts as a buffer barrier to block sharp stones, ore blocks and hard soil from directly hitting track chains, track rollers and idler wheels. It can greatly reduce surface abrasion, chain bending deformation and track derailment failures caused by foreign object impact. Compared with thin aftermarket split guards, our integral cast track guard extends the service life of the whole walking undercarriage by more than 40% under harsh mining environments, cutting frequent replacement costs of track and roller spare parts for machinery operators and maintenance merchants.
All casting, heat treatment and inspection procedures are completed in our self-owned casting and machining workshops without outsourcing, ensuring consistent structural thickness and stable mass delivery cycles for OEM bulk supporting orders. Every finished track guard passes full flaw detection and dimensional calibration with factory inspection reports, and all export products obtain CE certification with a 12-month quality warranty. Besides standard SD320 track guard models, our engineering team accepts customized thickened reinforced track guards for ultra-heavy mining working conditions according to customer requirements.
We maintain long-term stable OEM supply cooperation with domestic top construction machinery brands including Shantui, Sany and Liugong. Our bulldozer undercarriage castings are exported in large quantities to South Africa, Guinea, Tanzania, Saudi Arabia, Russia and Southeast Asian markets. Global machinery distributors highly recognize our track guard products for solid impact resistance, competitive FOB factory prices and flexible minimum order quantity. Our professional technical team provides matching installation guidance and timely after-sales technical support for all international machinery partners.
