The Kemer KST45000 is a hydraulic track undercarriage designed for mobile equipment requiring a high load capacity and stable tracked mobility. With a rated load capacity of 45,000 kg, 352 kN traction force and a maximum gradeability of 30°, the undercarriage is suitable for heavy-duty machinery operating on demanding job sites.
The KST45000 can be configured around the requirements of the host machine, including track dimensions, mounting interface, travel performance and hydraulic system specifications. OEM and custom engineering support is available for equipment manufacturers and project-based applications.
A track undercarriage consists of interconnected components such as track chains, sprockets, rollers, idlers, track frames and the travel drive system. Properly matched components help the tracked machine transfer load to the ground and maintain stable movement across different work environments.
Heavy equipment undercarriages are subjected to continuous loading, vibration and contact with soil, rocks and other job-site materials. Selecting appropriately sized undercarriage components helps support reliable machine operation and controls component wear.
The track system distributes machine weight over a larger contact area than a conventional wheeled system. This can help improve machine stability and mobility when operating on uneven or soft ground, depending on the machine configuration and site conditions.
Sprockets, rollers, idlers, track assemblies and hydraulic travel systems need to work together as a complete undercarriage system. Correct component matching is important for alignment, track tension, travel performance and serviceability.
Hydraulic track undercarriages can be engineered for different types of mobile equipment used in construction, material handling, forestry, mining and other off-road applications. Configuration depends on machine weight, center of gravity, required travel speed, hydraulic supply and operating conditions.
Regular inspection helps identify wear, contamination, leaks and mechanical issues before they affect machine operation. The following inspection points can be used as a general maintenance checklist. Always follow the host machine and component manufacturer's safety and service procedures.
Shut down and secure the machine: Make sure the machine is stopped, isolated and secured before beginning inspection.
Use appropriate protective equipment: Wear suitable safety glasses, gloves and protective footwear for the inspection environment.
Overall condition: Check the track undercarriage for visible wear, cracks, deformation, loose components, contamination and hydraulic oil leakage.
Track links and shoes: Inspect the track assembly for abnormal wear, cracks, damage or loose hardware.
Track tension: Verify that track tension is within the host machine manufacturer's specified range. Excessive looseness or excessive tension can affect wear and operating performance.
Adjustment system: Check the track adjuster and follow the manufacturer's approved adjustment procedure when correction is required.
Tooth wear: Check sprocket teeth for abnormal wear, chipping, deformation or excessive hooking.
Alignment: Confirm that the sprocket and track assembly are correctly aligned to help reduce uneven wear.
Roller condition: Inspect rollers for cracks, abnormal surface wear, damage and signs of seal leakage.
Rotation: Check that rollers rotate correctly and do not show signs of seizure or abnormal resistance.
Idler condition: Check the front idler for wear, cracks, deformation and other visible damage.
Track adjuster: Verify that the track adjustment system operates correctly and maintains the required track tension.
Remove accumulated mud, stones, debris and other foreign material from the undercarriage. Material trapped between components can affect inspection, track movement and service access.
After inspection and only when safe to operate the machine, pay attention to unusual knocking, grinding or other abnormal sounds that may indicate a mechanical issue.
Record component wear, observed damage, leaks and maintenance actions. A consistent inspection record can help support planned maintenance and component replacement decisions.
