The LHD with Intelligent System would help underground mine create an safety and healthy working environment and improve the work efficiency.   

HOT Low-profile LHD uses diesel as powder, adopts hydraulic transmission, articulated frame and front discharge bucket. The LHD has solid body structure, transversal arrange operators’ compartment, and equipped with mine cutting resistant engineering tyre and diesel exhaust purification plant, that is a kind efficient equipment suitable for producing mine and slag. Except for the underground mineral materials of loading, unloading and transportation, the LHD could also be used in railway, highway, and tunnel project, specialized in poor working conditions, narrow and low working site, and muddy working surface.  

LHD also combines with advanced intelligent technology of ALPHA company.jpg

Comparing with traditional LHD, this LHD also combines with advanced intelligent technology of ALPHA company, which has the function of remote operation and control of Internet of Things(IOT), Line of Sight control remote system and Predictive Maintenance(PdM). To ensure personal safety, especially when recovery of orebody in Goaf, the remote control is particularly important. Because of the unstable goaf environment and high risk factor, the operators are permitted driving vehicles in special area. So the ALPHA‘s remote control could handle this problem perfectly through vehicle mounted receiving unit to switch between the local and remote control, through handheld remote control to realize the remote point-to-point real-time control.

Remote function: monitoring center send instructions, remote LHD proceed all kinds operations, including forward, back, accelerator, turning left, turning right, lifting arm, lowering arm, loading, unloading, parking brake, auxiliary brake, fire extinction, starting engine, speed gear, abrupt stop, front light, back light, horn and all protected procedures.

At the same time, ALPHA also focuses on IoT date in the Cloud and intelligent analysis. Through LHD vehicular unit to real-time monitor the running status and unload to ALPHA intelligent analysis platform. The status information includes engine oil pressure, engine oil level, engine temperature, gearbox oil temperature, gearbox oil pressure, braking oil pressure, braking oil level, fuel tank level, mileage, driving time, engine working status, braking status, neutral position status, LHD forward, back, accelerator, turning left, turning right, lifting arm, lowering arm, loading, unloading, parking brake, auxiliary brake, fire extinction, starting engine, speed gear, abrupt stop, front light, back light and so on.

Through the intelligent analysis of cloud platform, real-time analysis of massive monitoring data and intelligent algorithm of platform, it can predict the equipment operation status and realize the safe protection of LHD. Before the LHD malfunction, we can get the notice from Wechat or APP to realize the PdM.
