1. Choose by Project Scale
Small-scale projects (e.g., indoor backfilling, rural roads):
Select medium-to-small models with a tamper energy of 5–20 kJ. These are lightweight (compatible with small excavators/loaders) and suitable for shallow compaction (0.5–3 meters).
Large-scale projects (e.g., highways, airport foundations):
Opt for large models with a tamper energy of 20–50 kJ or higher, capable of deep reinforcement (over 3 meters). They require matching with large equipment (e.g., excavators over 20 tons).
