Frequently Asked Questions
Q1: What advantages does the 360° horizontal rotation of the working platform and ±90° swing of the three-section boom bring to mining operations?
A: The 360° horizontal rotation of the working platform and ±90° swing of the three-section boom enable the equipment to achieve full-range operation without blind spots. It can flexibly reach various positions in the roadway, significantly improving the efficiency of excavation, trimming and other operations, especially suitable for the complex and confined working environment of underground mines.
Q2: How does the equipment avoid collision with roadway facilities such as rock bolts and roof during operation?
A: The boom height of the equipment can be flexibly adjusted according to the size of the roadway section. This design allows the equipment to avoid touching rock bolts, cable bolts and roadway roofs effectively, ensuring safe operation in roadways of different heights and reducing the risk of equipment damage and roadway structure damage.
Q3: Can this mining excavator be customized to meet different operation requirements, and what are the specific options?
A: Yes. The equipment supports multiple optional attachments, including hydraulic breakers, milling heads and hydraulic shears. By equipping different attachments, it can realize multi-functional operations such as rock breaking, milling and shearing, achieving the goal of one machine for multiple uses and helping buyers save the cost of purchasing multiple specialized devices.
