This product is an opening handle assembly on the inside of the driver's cab door. The handle body is made of black high-strength engineering plastic, with anti slip texture and grooves for easy finger insertion on the surface, which conforms to ergonomic design. Adopting original factory vacuum packaging, the packaging bag is printed with the red "HITACHI" logo, and usually contains the handle body and necessary installation screws or buckles inside. Its core function is for the driver to trigger the door lock mechanism by pulling inside the car to open the door.

Daily inspection: During weekly or daily pre shift inspections, you can easily operate and test. If you feel loose, stuck, or require abnormal force to open, you need to check. Replacement timing: When the handle is broken, severely worn, the internal mechanism is damaged, or loses elasticity, causing the door lock to fail to trigger normally, it should be replaced in a timely manner. Caution: Avoid using brute force during operation to prevent damage to plastic buckles or connecting rods; Avoid high temperature and heavy pressure during storage.
