When designing the HMK 145 LC SR crawler excavator, focus was placed on configuring the cabin so the driver will feel as relaxed and comfortable as he would be sitting in an office. To this end, the workplace was fitted with the Opera control system, which assists in operating. The compact excavator thus offers well-conceived ergonomics comparable to that of a heavy machine. The air conditioning is located at a special position that makes maintenance easy, and the tilting cabin offers quick access to the hydraulic system.
