PRODUCT FEATURES
1. The AT-4000L ,a next-generation digital track self- prpeled raise-boring machine, employs fully hydraulic drive technology. Itfeatures strong power delivered by a high-torque motor directly driving the gcarbox compact structure, high impact resistance, excellentoperational efficiency, and low deviation rate;
2. The track frame is sel lubricating and maintenance-free, wih excellent ground adhesion and wet-type hydraulic braking mechanism, allowingfor three-speed transmission, in-situ turning and other functions;
3. Requiring no concrete foundation pouring, this machine realizes instant setup for work upon arrival and rapid disassembly and transfer uponcompletion, saving substantial time for foundation pouring, installation and disassembly;
4. Designed with a modular structure. the machine can be disassembled into sections under 3 meters for convenient cage transportation;
5. All operations support wireless remote control and dual-mode backup between wireless control and wired lever control, ensuring high reliability;
