Crane track shoes are individual units of the crawler track that work with other crawler undercarriage parts such as track links, bottom rollers, and sprockets to ensure the crawler crane moves smoothly and efficiently.
Main functions of crane track shoes:
Support and stability: Crawler track shoes evenly distribute the weight of the crane, prevent excessive ground pressure, and ensure stability when operating on challenging surfaces.
Traction: They help the crane move forward or backward by gripping the ground and preventing slipping, especially on uneven, muddy, or soft terrain.
Durability: Crane track shoes are usually made of durable steel or other high-strength materials to withstand harsh working conditions, including rough terrain, extreme weather, and heavy loads.
To replace the crane track shoes, you'll need a few essential tools: a hydraulic jack or lifting equipment to raise the crane, wrenches and impact tools to remove bolts, and a torque wrench to properly tighten them. If the shoes are heavy, lifting straps or slings will help with handling. Wear safety gloves, goggles, and steel-toed boots for protection. A hammer can be used for stubborn bolts. These tools ensure a safe and efficient replacement process.
First, ensure the crane is on level ground, activate the parking brake, and stabilize the crane. If needed, block the tracks with wedges to prevent movement. Then, use a hydraulic jack or lifting equipment to raise the crane, relieving weight from the track shoes for easier removal.
Locate the bolts or pins securing the track shoe to the track link, which may be held with nuts and washers. Use a wrench, socket wrench, or impact tool to loosen them. For stubborn fasteners, apply penetrating oil and tap with a hammer. If needed, remove the track shoe in sections or detach a specific link. Once all bolts/pins are removed, carefully lift or slide the track shoe off, using a sling or extra help if it's heavy.
Prepare the new track shoe by ensuring it meets the crane's specifications and cleaning the installation area. Align the new shoe with the track link, matching the bolt/pin holes. Insert the bolts/pins and secure with nuts and washers, tightening them to the manufacturer's recommended torque to ensure a secure fit.
Ower the crane slowly once the track shoe is installed. Check alignment by manually rotating the track or driving the crane forward to ensure smooth movement and listen for any unusual sounds. After testing, recheck the bolts or pins to ensure they are properly tightened, using a torque wrench if needed.
Conduct a final inspection of the entire track system, checking for misaligned or loose components. Perform a test run under low load conditions to ensure proper track function, monitoring for any unusual behavior during movement.
