Komatsu HD465-7

Double tap to zoom



715 net hp drive the 61 ton capacity HD465-7. A very tight turning radius and hydro-pneumatic suspension makes the HD465-7 very maneuverable in close working areas. Cast-steel in high stress areas on the frame give the truck the durability and reliability mines demand today. Two working modes and a seven speed fully automatic transmission with lock-up and skip shift give the HD465-7 power and speed to meet today’s production levels.
