Komatsu LC755-3-ME(S/N 30001-UP)
Maintenance schedule, common problems & OEM parts breakdown
The Komatsu LC755-3-ME is a 4.9-ton mini crawler crane designed for precision lifting in confined spaces. It is powered by a Komatsu 4D102E engine rated at 40.5 kW (55 PS) at 1,750 rpm. The machine features a fully hydraulic 5-section telescopic boom extending from 4.56 m to 15.56 m, with a maximum lifting height of 16.35 m and a working radius of 14.45 m. Dimensions are 4,490 mm in length, 2,230 mm in width, and 2,545 mm in height, with a transportable weight of approximately 9,600 kg. It is part of Komatsu's historical mini crane lineup, which also included rail and city-class rough terrain variants.
Komatsu has ceased manufacturing telescopic cranes, making the LC755-3-ME a discontinued model in the used market. Its significance lies in its compact footprint and high maneuverability, which remain valuable for industrial plant installations and interior building work where larger cranes cannot operate. The machine's reliability and specific hydraulic configurations continue to drive demand for its specialized parts and service expertise.

Servicing the LC755-3-ME(S/N 30001-UP) beyond the schedule
Predictive Maintenance & Fluid Analysis
Utilize KOWA fluid analysis at every major service interval to monitor engine wear metals, hydraulic particle counts, and coolant pH levels. The 4D102E engine requires Komatsu Genuine Lubricants to maintain strict engineering standards. Regularly sample hydraulic oil for viscosity changes and oxidation. Monitor DEF levels daily to ensure Tier 4 emissions compliance. Track fuel dilution and soot levels in the engine oil to predict injector or piston ring wear before failure occurs.
Corrective & Common Repairs
Address hydraulic hose cracks and leaks immediately to prevent system contamination. Inspect the 5-section telescopic boom for structural fatigue or weld cracks during the 1,000-hour structural inspection. Check the swing bearing and travel system for excessive play. Replace the hydraulic return filter and fuel filter at 500-hour intervals to protect the high-pressure pumps. Verify the integrity of the electronic monitoring systems for the hoist drum rotation and other critical operations.
Overhaul & Rebuild Points
Plan major overhauls at 2,000-hour intervals, including hydraulic oil changes, coolant flushes, and transmission service. Inspect the turbocharger and perform valve adjustments as needed. Evaluate the undercarriage wear at 500-hour intervals to determine track chain and sprocket replacement timing. Comprehensive component evaluation at 2,000 hours identifies wear in the derrick cylinder and hook block mechanisms. Replace worn belts and clamps to prevent secondary engine damage.
Seasonal & Environment Servicing
Clear debris from the radiator and oil cooler fins daily to prevent overheating in dusty or hot environments. Check track tension and shoe condition regularly to maintain stability on soft or uneven ground. Inspect the air filter restriction indicator frequently in high-dust conditions. Ensure the cooling system SCA levels are adequate for the operating climate. Verify that the DEF system is protected from freezing in cold weather operations.
