Prior to loading operations, the swing mechanism of the挖掘装置 should be positioned in the middle and secured with a pull plate. During loading, use the low-speed gear. When lifting the bucket arm, avoid using the valve's floating position. The hydraulic control system's distribution valves are divided into front and rear sets of four valves each. The front four valves control the legs, lifting arm, and bucket for leg extension and loading tasks; the rear four valves operate the bucket, rotation, boom, and handle for rotation and excavation tasks. The mechanical power performance and the hydraulic system's capacity do not permit nor allow simultaneous loading and excavation operations.
The general mining loader (double-duty) is primarily powered by a wheeled tractor, with loading and digging attachments added to the front and rear, respectively, increasing the machine's length and weight. Therefore, it should avoid high speeds or sharp turns while in motion to prevent accidents. Do not coast downhill in neutral. When the hydraulic piston rod of the bucket and handle is fully extended, it allows the bucket to close to the boom, placing the digging attachment in its shortest state, which is beneficial for travel. During travel, the support legs should be fully retracted, the digging attachment should be securely fastened, the loading attachment should be lowered, and the hydraulic piston rod of the bucket and handle should remain fully extended.
