Verified model comparison
Shortlist these excavators around the trench, truck and lift tasks you actually perform, then compare the documented boom, arm, shoes and counterweight.
Digging depth and ground reach answer different questions. Plot the required trench bottom and spoil position separately, then check loading height against the truck body. The table retains each record’s configuration; a longer arm can change the working envelope without indicating a stronger or more productive machine.
Ask for a cold start followed by a warm digging and loading demonstration with comparable material and buckets. Record cycle consistency, cylinder drift, slew response and visibility from the actual cab. Inspect the undercarriage quantitatively and obtain a parts estimate before interpreting a lower purchase price as lower cost.
Carry transport width, attachment requirements and local service response into the decision. If one example includes a coupler, guarding or guidance system, price the other to the same usable specification. Neither published engine power nor maximum reach establishes lift capacity at your planned radius.
Generation/configuration-aware: measurement basis and reference configuration travel with each value. A difference in basis is not treated as a performance difference.
