Operating weight 6710kg, rated power reduced to 34.1kW. Higher spare‑part cost. ## Notes for Used & Overseas Business - The ‑5A with Isuzu engine enjoys good reliability in field operation. - For EU export: prefer **ZX70‑5G (CE certified)**. Domestic ZX70‑5A has no CE certificate and cannot clear EU customs. - Auxiliary hydraulic line: Factory‑option hammer piping. 178.5L/min main pump flow suits 6‑7 ton hydraulic breakers.
