Komatsu PC200 LC-8 Overview
The Komatsu PC200 LC-8 is a mid-sized hydraulic excavator widely used in construction, mining, and heavy civil works. Introduced in the mid-2000s as part of Komatsu’s PC200 series, it replaced the PC200 LC-7 with enhanced hydraulic efficiency, improved operator ergonomics, and stronger structural components. The machine’s rated operating weight is officially listed around 45,000 lbs (20,400 kg), with a standard bucket capacity of 1.0 m³ for general-purpose digging. Over its production run, Komatsu sold tens of thousands worldwide, establishing the PC200 LC series as a workhorse in both developed and emerging markets.
Reported Weight Discrepancy
Several operators have reported that the actual in-field weight of their PC200 LC-8 can exceed the manufacturer’s listed figure by as much as 3,000 lbs (1,360 kg). This discrepancy is often influenced by:
Operating a PC200 LC-8 that exceeds the nominal weight has several practical effects:
Operators should verify weight distribution and consider the following strategies:
In one reported case, a contractor hauling a PC200 LC-8 with an extra thumb attachment exceeded bridge load limits by 2,500 lbs. The company had to obtain a special permit and adjust transport routes, highlighting the importance of checking total machine weight before road transport. In another scenario, lifting operations on a soft clay jobsite showed slight instability due to added weight from a reinforced bucket, emphasizing that even minor weight increases can affect operational safety margins.
Conclusion
While Komatsu’s PC200 LC-8 is engineered for durability and versatility, real-world weights often surpass nominal specifications due to attachments, fluids, and operational additions. Operators must account for these variations to maintain safety, comply with transport regulations, and optimize machine performance. Proper weighing, careful planning, and understanding the impact of extra weight on lift capacity and ground pressure are crucial for efficient and safe operations. By addressing these factors proactively, owners can prevent costly accidents and maximize the productivity of their excavator fleet.

Reported Weight Discrepancy
Several operators have reported that the actual in-field weight of their PC200 LC-8 can exceed the manufacturer’s listed figure by as much as 3,000 lbs (1,360 kg). This discrepancy is often influenced by:
- Additional Attachments: Hydraulic thumbs, quick couplers, or reinforced buckets increase weight beyond OEM specifications.
- Fuel Load: A full fuel tank adds roughly 200–300 lbs, which contributes to overall weight.
- Hydraulic Fluids and Coolants: Fully topped-off hydraulic oil and engine coolant can account for 400–600 lbs extra.
- Track and Undercarriage Wear: Replacement steel tracks or track shoe extensions can add significant mass.
- Optional Counterweights: Some units shipped with extra counterweights for lifting heavy loads or stabilizing excavators on uneven terrain.
Operating a PC200 LC-8 that exceeds the nominal weight has several practical effects:
- Transportation Limits: Overweight equipment may violate legal road limits, requiring special permits or trailers rated for higher loads.
- Lift Capacity: Exceeding weight limits can reduce the safe lifting capacity of the boom and arm, altering stability calculations.
- Ground Pressure: Extra weight increases ground pressure, potentially causing soil compaction or reducing mobility in soft conditions.
- Fuel Efficiency: Heavier machines consume more fuel per operating hour, impacting operating costs over the machine’s lifespan.
Operators should verify weight distribution and consider the following strategies:
- Weigh Machines Accurately: Use certified scales at equipment yards to measure exact weight, including attachments and fluids.
- Adjust Counterweights: If possible, remove unnecessary counterweights when not performing heavy-lift tasks.
- Monitor Lift Charts: Recalculate boom and arm lift capacities with the actual operational weight for safety compliance.
- Plan Transport Carefully: Use transport trailers rated above the measured gross weight to ensure safe over-road movements.
- Track Wear Management: Maintain or replace worn track shoes with lighter alternatives when heavy attachments are frequently mounted.
