Bulldozer Maintenance and Care
Bulldozer Maintenance: The Three Essentials Proper bulldozer maintenance hinges on three key areas: daily inspection, scheduled replacement, and critical component care. Mastering these points is the most effective way to extend your equipment's service life. The Focus of Maintenance 1. Never Skip Daily Checks Before and after operation, always inspect fluid levels (oil, water, diesel), clean the exterior, and check for loose bolts and abnormal instrument readings. Address any oil or water leaks immediately to prevent further damage. 2. Strictly Follow Scheduled Replacements Replace engine oil, filters, and hydraulic oil based on operating hours. First Service: Typically at 500 hours. Subsequent Service: Every 500 hours thereafter. Air Filter: Clean or replace the air filter whenever it appears dirty. 3. Meticulous…
Maintenance & Repair of Used Motor Graders
Upon purchasing a used motor grader, the core strategy must be "Comprehensive Inspection, Proper Break-in, and Strict Maintenance." Due to the unknown history of previous usage, it is critical to focus on hidden wear and oil contamination. Systematic maintenance is required to restore performance and extend service life. I. In-Depth Inspection Upon Purchase (Critical Steps) Before deploying the machine for high-intensity operations, a full teardown-level inspection is necessary to prevent operating with existing faults. Powertrain System: Check engine oil for metal shavings (indicating cylinder or bearing wear). Test torque converter outlet pressure and oil temperature; if the oil contains a large amount of aluminum particles and the temperature spikes rapidly, this indicates damage to the pump or turbine wheel, requiring…

Used Cat Excavator: 7 Checks Before You Buy
A used Cat excavator can help you add digging capacity without paying the full price of a new machine. It can also become an expensive problem if you focus only on the model year, paint, or hour meter. You may find two excavators of the same model with nearly identical hours, yet one is ready to work while the other needs an undercarriage, hydraulic repairs, and emissions-system service. The difference often comes down to how the machine was operated, maintained, stored, transported, and repaired. The market also changes quickly. In May 2026, inventory for used heavy-duty construction equipment in the United States was down 11.55% year over year. Used crawler excavator inventory fell 1.41% month over month, while crawler excavator…

Bulldozer Operation: Safety and Precautions
The operation of bulldozers must strictly adhere to the principle of "Inspect First, Operate Safely, No Violations." The core precautions are as follows: I. Pre-Operation Inspection & Site Assessment 1. Equipment Static Check Verify that engine oil, coolant, and hydraulic fluid levels are normal and free of leaks. Check track tension (sag should be between 10–20 mm) and ensure all bolts are tight. Test the functionality of brakes, steering, lights, and the horn. 2. Environmental Safety Survey Identify the location of underground pipelines and cables; mark them clearly. Remove large obstacles from the work area. Confirm the slope does not exceed equipment limits (typically ≤10° laterally, ≤30° longitudinally). Prohibition: Operation is strictly forbidden at night or during severe weather (heavy…
