VOLTER: Battery-Powered Monorail
The Energy of the Future Underground
VOLTER is an explosion-proof battery-powered monorail designed for transporting personnel and materials in underground mines.
It combines a high level of operational performance with full compliance with environmental requirements — representing a new generation of solutions in the Becker MineTrans® system.
Quiet operation, zero exhaust emissions, and remote control capability make VOLTER ideal for methane hazard zones and all environments where safety, reliability, and operator comfort are essential.

Technology and Drive System
VOLTER is equipped with a lithium iron phosphate (LFP) battery system with a high capacity of 142 kWh, integrated with a Battery Management System (BMS) and PLC controller.
The CAN 2.0B communication system enables integration with Becker MineTrans® digital systems, while off-board charging allows fast and safe charging outside the machine.
The drive system uses BWNE electric friction drives, providing high torque, smooth speed control, and the ability to recover energy during braking.
