In the short-distance material transportation project of a mountainous mine area, the traditional operation mode is facing severe challenges - the steep terrain makes it difficult for excavators and transport vehicles to coordinate, resulting in low material transportation efficiency and high costs. However, the new tracked transport vehicle equipped with the Q345 manganese plate arm assembly, relying on the innovative design of "excavation-transportation" integration, has successfully solved the problem and become the key to accelerating the project.
The person in charge of the mine project revealed that the previous operation mode of "excavator + ordinary tracked transport vehicle" had the following problems: due to the rough roads in the mine, the excavator had to dig in a fixed area, and then the transport vehicle had to detour to the operation point for loading. The single material transportation cycle was as long as 40 minutes. Moreover, the frequent scheduling of excavators and transport vehicles easily caused damage to the road surface due to rolling. However, the newly put into use integrated tracked transport vehicle, with the arm assembly made of Q345 manganese plate, has significantly improved the operation efficiency: the arm can directly complete the ore excavation on the vehicle body, and then the transport vehicle can realize material loading without moving. The single transportation cycle is shortened to 15 minutes, the daily operation volume is increased by 160%, and the maintenance cost of the mine road surface is reduced by 30% due to the reduction of equipment round trips.
The excellent performance of this arm assembly is inseparable from the strong support of Q345 manganese plate. As a high-strength low-alloy structural steel, Q345 manganese plate has a yield strength of 345MPa. While ensuring the lightweight of the arm, it endows it with super bearing capacity - when facing ore excavation operations, the arm body has no obvious deformation, ensuring stable excavation depth and grasping force; its excellent toughness is like a "dynamic buffer layer". When the tracked transport vehicle is driving on bumpy roads, it can absorb the impact of the vehicle body vibration on the arm, avoiding the weld cracking problem of traditional steel due to excessive rigidity, and extending the service life of the arm assembly to 1.5 times that of traditional products.
In the "excavation-transportation" integrated operation, the advantages of the Q345 manganese plate arm assembly are further amplified: first, the uniform mechanical properties of the material ensure the precise movement of the arm. Cooperating with the stable chassis of the tracked transport vehicle, it can complete excavation and loading on a 35-degree slope, solving the problem of "shaking and inaccuracy" of traditional equipment in complex terrain operations; second, the lightweight feature reduces the center of gravity of the whole vehicle, making the transport vehicle turn more stably when fully loaded, with the passability improved by 40%, adapting to various complex working conditions such as mines and muddy construction sites; third, the integrated design of the arm and the transport vehicle reduces the equipment connection loss. Compared with the split operation, the energy consumption is reduced by 25%, and due to the corrosion resistance and easy maintenance of Q345 manganese plate, the monthly maintenance time of the equipment is shortened to 2 hours, which is far lower than the 8 hours of the traditional arm.
"What used to be done by two pieces of equipment can now be done by one vehicle. Especially the arm is powerful and durable, and it doesn't 'break down' even after 10 hours of continuous operation," the on-site operator spoke highly of the equipment. At present, this tracked transport vehicle equipped with the Q345 manganese plate arm assembly has been widely used in mines, infrastructure projects and other places. Its "efficient, durable and all-round" performance is redefining the material operation mode in complex terrain.
