About Kobelco CKE2500 Crawler Crane
The KOBELCO CKE2500 is a 250-ton lattice boom crawler crane. It works mainly for wind power projects, infrastructure, bridge construction and heavy lifting jobs. Undercarriage parts are wear-prone parts.You need regular inspections and timely replacements once they wear out. The full set of Kobelco CKE2500 undercarriage parts includes track shoes, track rollers, carrier rollers, idlers and sprockets.
Full Range of Kobelco CKE2500 Undercarriage Parts
The Kobelco CKE2500, as a 250-ton-class heavy-duty crawler crane, is widely used in heavy-load projects such as wind turbine installation, bridge construction, and large-scale infrastructure development. The undercarriage parts, which operate continuously on rocky, muddy, and uneven terrain, are the most wear-prone parts.Appropriate replacement parts can reduce equipment downtime and ensure project schedules.Now we will walk you through the track shoes, track rollers, carrier rollers, idlers and sprockets built for this crane model.
1 CKE2500 Crane Track Shoe
Made for the heavy-duty Kobelco CKE2500 crawler crane, these parts use premium alloy steel as raw material. The full production process includes casting and bulk heat treatment to strike a good balance between hardness and toughness.This track shoe features a widened plate design to spread the crane’s total weight and reduce ground pressure. It resists sinking and slipping when working on soft or muddy job sites.It holds steady against constant abrasion from gravel and repeated rolling loads. It extends the service life of the whole track assembly and counts as one of the frequently replaced undercarriage wear parts on site.
2 CKE2500 Crane Bottom Roller
Track rollers serve as the main load‑bearing parts for the CKE2500 undercarriage. They carry most of the crane’s total weight and take repeated impacts from rocks on the ground while the machine travels.We machine these rollers from forged blanks. Quenching and tempering heat treatment makes the outer surface wear-resistant while keeping the core tough enough to avoid chipping or cracking.They come with proven floating oil seal assemblies fitted with imported seal rings. The seals block sand and mud from getting inside the roller, fixing the common industry issues of oil leaks and premature failure. We check dimensions and hardness on every finished roller. They match original mounting specs perfectly for easy fitting, and keep the crawler crane running steadily through long continuous shifts.
3 CKE2500 Crane Carrier Roller
Carrier rollers sit on the upper section of the undercarriage. They hold up the top track chain, limit track sag, and stop heavy shaking, chain jumping or derailment when the crane travels at speed. This CKE2500 carrier roller starts with carefully machined blanks. Professional heat treatment boosts wear resistance on the roller surface. It spins smoothly and cuts extra friction between the track links and roller. We run dimension checks and flaw inspection on every unit before shipment to rule out hidden internal defects.
4 CKE2500 Crane Idler
The idler works together with the track adjuster cylinder and recoil spring. It guides the track, absorbs impacts and adjusts track tension to prevent track deviation. Our idler made for the CKE2500 uses one-piece forming and goes through full heat treatment. It balances impact toughness and surface wear resistance, standing up to repeated blows from the track links as the crane moves. High concentricity machining lets it rotate freely. It guides the track smoothly and cuts uneven wear on links and pins. It passes multiple quality checks before leaving our factory. Dimensions meet OEM replacement standards, so you can swap it in directly without extra modification or adjustment.
5 CKE2500 Crane Sprocket
The sprocket is the power hub of the travel system. It meshes its teeth with track links to pass power from the travel motor and move the entire crane. Made for the heavy loads of the CKE2500, its tooth profile copies the original shape precisely. This delivers smooth meshing and even load distribution, avoiding track jamming or tooth skipping.
We apply special surface hardening on the teeth. The tooth face stands up to wear while the tooth root retains solid strength, reducing chances of broken teeth and fast abrasion under continuous heavy power transmission. We use ultrasonic inspection in production to catch hidden flaws like internal pores and cracks. The part gets released for shipment only after hardness and dimension tests pass, to maintain steady power transfer for heavy lifting projects.
Our Manufacturing & Quality Control
Manufacturing
We make crawler crane undercarriage parts with either casting or forging for blanks, based on what each component needs. Once the blank takes shape, we start rough machining to cut away excess stock and shape the outline, getting it ready for heat treatment later.
Heat treatment comes next. We first carry out quenching and tempering to temper the workpiece. This gives it balanced hardness and inner toughness so it does not snap easily under impact. For areas that see constant friction, such as roller bodies and tooth surfaces, we add a second surface hardening step. This boosts surface wear resistance and extends service life when parts work in rough, rocky or muddy job sites.
After heat treatment, we move to finish machining. We refine the workpiece and hold all dimensions within OEM tolerances. The finished surface is smoother, and the part fits without hassle during installation. We then assemble components and spray protective topcoat paint. Every finished part goes through our full quality control sequence. We pack the goods and arrange shipping only once all inspections are passed.
Quality Control
Before production starts, we test the raw material’s chemical makeup and basic mechanical properties. We confirm the material meets our production specs and rule out substandard material issues right at the source.
When parts reach the final inspection stage, we use a full set of equipment for complete verification:
Coordinate measuring machines take high-precision dimension readings on key areas of the workpiece and pick up tiny deviations on complex profiles;
Handheld 3D scanners quickly scan the overall shape. We compare scans against original samples to spot any shape distortion fast;
Metallurgical microscopes let us view the steel’s internal grain structure and check whether grain conditions after heat treatment are up to standard;
The universal testing machine measures tensile and compression performance to verify structural strength;
Ultrasonic flaw detectors look deep inside workpieces and find hidden defects such as pores and cracks;
Impact testers check how well parts resist shock loads, making sure they do not crack under impacts on site.
We also carry out routine random dimension checks. This whole inspection workflow guarantees all finished parts stay within OEM tolerance limits. They fit properly and install smoothly on the crane.
