West-Trak is here to support you with any crawler crane undercarriage parts
Maintaining Your Crawler Undercarriage
Maintaining your tracked undercarriage is important to keep your crawler crane running in top condition. Here are a few tips for maintaining your tracks:
- Inspect the tracks and components regularly and listen for unusual noises – high pitched/squealing sounds indicate wear points.
- Check the tension of the tracks chains as per the manufacturer’s guide. Loose tracks mean accelerate wear.
- Clean the undercarriage to remove dirt, debris, and other contaminants especially around the sprocket and idler areas. Packed debris acts like an angle grinder!
- Check Track Shoes, Final Drives, Roller and Sprocket bolts and nuts as per the service requirements laid out in the machine operating manual. A loose bolt will cause elongation and expensive damage.
- Feel for heat spots in track rollers and idler centres – these indicate loss of lubricant and imminent failure.
To keep them running in top condition, you need to make sure you’re maintaining the crawler undercarriage.
Sourcing Crawler Undercarriage Parts
Finding crawler undercarriage parts for your tracked crane has never been easy – it’s an expense that comes up only once every seven or eight years on a crane so choice is often limited to the original manufacturer or his distributor.
West-Trak is here to supply you with all your crawler crane undercarriage parts. We stand out from our competitors. Our prices are realistic, and our component quality is not negotiable.
The shells of our track rollers are manufactured from hard-wearing 40Mn2 steel, extending service life. The bushings are industry-leading 6-10 mm thick pure copper rather than a less hard-wearing duplex combination of iron and copper, and our pins are made of tested and tried robust 42cr steel.
This attention to quality and performance is the same across the range – track shoe assemblies, chains with conventional bolt-on pads. idlers, and sprockets, all built to fit, perform and last.

The Foundation of Stability: The Crawler Undercarriage
Starting from the undercarriage and base of a crawler crane, often simply called the ‘crawler,’ this is no ordinary set of wheels. This robust undercarriage boasts a set of continuous tracks that distribute the crane’s weight evenly across the ground. This unique design gives crawler cranes exceptional stability, allowing them to operate on uneven terrain and lift massive loads without tipping over.
The crawler undercarriage itself comprises several key components, including:
Track Shoes:
Durable steel segments that form the tread of the tracks, ensuring smooth movement and providing traction on various surfaces.
Track Rollers:
Rollers that support the track shoes for smoother movement.
Sprocket and Idler Wheels:
The drive sprockets at the front engage the tracks, propelling the crane forward or backward. The idler wheels at the rear maintain tension in the tracks.
Carrier Rollers:
Additional rollers positioned along the underside of the tracks for further support and smoother travel.
