The XMPYT roof-cleaning trolley produced by our company is a specialized piece of equipment widely used in China’s non-coal mines for addressing the hazards of roof and sidewall collapses in mine shafts and tunnels. It is also known as a tunnel-cleaning machine or a roof-lifting trolley. Currently, the standardized XMPYT series of roof-cleaning trolleys includes three main general models: the XMPYT-97-700A, the XMPYT-97-700B, and the XMPYT-45-450. Each model, further refined and customized according to specific application requirements, can be configured in various specialized versions, including general-purpose models, high-altitude climate-resistant models, high-temperature environment-resistant models, dual-operator models, and remote-control operation models.
1. The scientifically and rationally designed structural configuration meets the requirements of various underground mine conditions, including turning radii, gradeability, and passage for mining operations in tunnels and shafts. Specifically, the vehicle features a dedicated chassis, a front-mounted bulldozer blade, a fully sealed wet-type axle (with pressure-loss protection), and a matching MICO braking system from the U.S., along with a remote-control operating device—all of which ensure safety, stability, and reliability, placing it at the forefront of the industry.
2. Utilizing high-strength structural steel stamping processes, Haoke Energy Stress Aging Treatment, and gas-shielded welding technology, the vehicle’s structural components have undergone strength verification and are capable of withstanding heavy loads.
3. The rotary structural design of the working arm and the chipping hammer head provides a wide coverage area, meeting the requirements for all-around chipping and hazard removal operations.
4. The key components of the hydraulic system—including the chipping hammer, hydraulic oil pump, spool-type proportional control lever, solenoid valve assembly, hydraulically controlled multi-way valve, priority valve assembly, rotary reducer, swing cylinder and hydraulic cylinder, and braking system—are all sourced from high-quality domestic and imported brands. These components boast reliable quality and performance, a high safety factor, energy efficiency, reduced consumption, and smooth operation.
5. The system oil temperature is controlled using air-cooling technology, which is scientifically sound, reasonably designed, and features low operation and maintenance costs.
6. The cab and control system feature a well-designed, ergonomically optimized layout. Equipped with a sealed, air-conditioned cab, a dual-seat cab, centralized controls, and remote operation capabilities, the design is both scientifically sound and remarkably comfortable and effortless. The entire vehicle boasts safe and stable operation, exceptional maneuverability, remote control functionality, rapid evacuation capability, and robust protective features—fully highlighting the characteristics of modern mechanized equipment.
