The Most Likely Candidate: A Sumitomo LHD-Series Excavator

The strongest match for the model number “HLD-80” is Sumitomo’s family of heavy-duty crawler excavators. Their model numbers use the “SH” prefix, but many of their machines intended for demanding work in quarries and mines carry the “LHD” (Heavy-Duty) designation .

A model like the Sumitomo SH800LHD-5 is an 80-tonne class machine, which aligns perfectly with the “80” in “HLD-80” . Based on the specifications of this model, the HLD-80 would be a machine of this caliber:

• Operating Weight: Approximately 80,100 kg (176,590 lbs) .

• Engine Power: A robust engine producing around 377 kW (513 PS) .

• Bucket Capacity: A large bucket ranging from 3.3 m³ up to 5.0 m³, depending on the configuration and material density .

• Performance: This class of excavator is designed for high productivity, featuring powerful digging forces. For instance, the SH800LHD-5 can achieve a bucket digging force of up to 460 kN with a Mass excavation bucket . It is engineered for large-scale earthmoving and mining projects .

What “HLD-80” Signifies

Based on standard industry naming conventions, the model name breaks down as follows:

• HLD: This likely stands for “Heavy-Duty” or “High-Lift” and aligns with the naming of other large excavators used in mining .

• 80: This number typically refers to the machine’s weight class. In this case, an “80” would indicate an 80-tonne (80,000 kg) class excavator .

Potential Alternative: A Different Manufacturer

It’s also possible that the “HLD-80” is a model from another manufacturer using a different naming system. For example, many brands have model numbers for their large excavators, such as the Hyundai HX series, which includes models like the HX480L (a 48-tonne class machine) .
