American Crane Parts
American crawler cranes are widely deployed across global infrastructure projects, wind farm construction and petrochemical engineering works. We have specialized in manufacturing American crane undercarriage parts for well over a decade. We are capable of supplying full matched travel system assemblies to fit all classic American crane models, including the HC range and heavy-duty 900 series. Every single undercarriage part we produce is built to match official OEM drawings, so clients can carry out direct replacement installation as soon as the goods arrive at their worksite.
Available Model
American 5299, 5300, 500, 700 Series, 7250, 7260, 900, 900 Series, 9260, 9299, 9310, 9320, 11320.
Our Product
We offer a complete set of American crane undercarriage parts
American Crane Track Shoes
Track shoes, connecting shafts, nuts, and bolts make up the full track assembly for crawler cranes. We produce our crane track shoes using different premium alloy casting materials, including 35SiMn, 31Mn2Si, 28CrMnMo, 31Mn2SiMo and 28CrMnMoNi. We select the appropriate raw alloy grades separately according to the lifting tonnage of each crane model to match its load demands. Every finished track shoe holds precise coaxiality after finishing machining. This precise dimensional control ensures smooth assembly on site and lets maintenance crews complete installation quickly without extra adjustments.
American Crane Bottom Rollers
Bottom rollers stand as the key load-bearing part within all American crane undercarriage parts, tasked with supporting the full weight of the entire machine unit. This critical role places extremely high standards on the rollers’ resistance to heavy impact and abrasive wear. Every bottom roller we produce goes through a two-stage heat treatment process combining quenching and tempering. This balanced treatment delivers ideal matching of surface hardness and internal toughness, so the rollers will not crack or split even after long stretches of continuous heavy-load operation. Beyond the dual heat treatment step, each roller body also receives dedicated surface quenching work. After this finishing procedure, its surface hardness hits HRC52 to 56, which drastically boosts overall wear life when working on rough construction and mining ground.
American Crane Top Rollers
Crane top rollers are also commonly called carrier rollers or upper rollers in the machinery industry. Just like our American crawler crane bottom rollers, every one of our top rollers goes through rigorous standard heat treatment procedures. Both our upper and bottom rollers are fitted with advanced floating oil seal structures paired with imported rubber O-rings. This reliable sealing setup successfully stops mud, gravel and other construction debris from seeping into the roller’s inner cavity, and also prevents lubricant oil leaks during long working shifts. With these reliable sealing components in place, the overall service lifespan of all our top and bottom rollers gets a noticeable upgrade.
American Crane Idlers
Every idler we make for American crawler cranes is integrally cast from standard premium 35SiMn alloy steel. Unlike ordinary carbon steel alternatives, this silicon-manganese alloy boasts better toughness and wear resistance, resisting cracks and fast abrasion under gravel-heavy loads on mining and construction sites. Precision boring on central shaft holes adheres strictly to American OEM tolerance standards. Post-installation, the wheel turns smooth without jams, eliminating eccentric wear and track derailment from uneven track stress during long-hour operation. Each finished guide wheel passes full dimensional inspection before shipment to guarantee consistent performance for all crawler crane equipment.
American Crane Sprockets
Sprockets serve as the power core of crawler crane travel assemblies. Their gear teeth mesh with track chains to transfer driving force, enduring frequent impact and constant abrasive wear. Like our guide wheels, each drive wheel is integrally cast from high-purity 35SiMn alloy steel, featuring robust base strength and great toughness to absorb persistent track impact loads.
We apply high-frequency surface quenching to load-bearing gear teeth to build a thicker hardened wear layer, with precise machining for tooth profiles, mounting holes, and inner shaft bores. All dimensions match American OEM specs, enabling steady power transfer and greatly lowering failures, including abrasion, broken teeth, and structural deformation.
What other services can we provide?
Comprehensive after-sales service support
Strict quality inspection is an essential step before shipping all American crane undercarriage parts. We test raw steel before machining to spot internal impurities, cracks and other material defects. Post-casting non-destructive testing finds hidden pores and concealed cracks inside each casting. Finished pieces get full dimensional checks matching American OEM standards, plus hardness verification after heat treatment. We can provide inspection photos, videos and official test documents if clients require supporting proof.
Fast delivery mechanism of American crane undercarriage parts
We keep ample stock of regular American crane undercarriage parts all year round to cut financial losses brought by prolonged equipment downtime for clients. Once a customer’s order gets confirmed, we arrange shipments without delay. Our dedicated logistics team tracks cargo transit status end-to-end and supplies all customs paperwork buyers need for clearance.
Comprehensive after-sales service support
Our official warranty covers up to 2500 working hours, which shows our full confidence in our part quality as well as our sincere commitment to every customer. Our after-sales staff remain reachable around the clock; we will give prompt replies to all issues related to product quality or fitting compatibility once you raise them. Whenever clients need assistance, we can deliver detailed remote installation guidance via video calls to help with on-site assembly and troubleshooting.
