About us

VULKAN Group, a Germany company, supports MINING Industry through its VULKAN DRIVE TECH business division, specialized in power transmission solutions: brakes systems, rail clamps, backstops, couplings, as well as driving tailored made solutions. Within the Mining industry, stackers and reclaimers, conveyor belts, mills, crushers, are typical heavy duty machinery whose drives are characterized by shock loads and dynamic displacement of large masses with big inertias. FLUID COUPLINGS for soft starting of the machinery, FLEXIBLE COUPLINGS for speed shaft, SERVICE BRAKES and resilient MOUNTS are typical products used for these applications that are part of VULKAN DRIVE TECH portfolio. Inclined conveyors also require safety equipment in order to maintain the stability of the transported material in emergency conditions. Such situations include failure of the drive train and the resultant rolling back of the belt with a potentially dangerous depositing of the goods at the tail end. All such demanding can be supported by VULKAN DRIVE TECH Solutions.

Products and services

VULKAN Drive Tech portfolio includes Flexible Couplings, Fluid Couplings, Rigid Couplings, Brake Systems, Clutches, Backstops and Mounts, as well as driving tailored solutions.

At applications such as BELT CONVEYORS, STACKERS AND RECLAIMERS, our FLEXIBLE COUPLINGS are generally installed onto high speed shaft of the drive train and onto low speed shaft, between the gearbox and the pulley. While our BACKSTOPS AND BRAKE SYSTEMS are properly selected to withstand the most critical working conditions to which the conveyor will be subjected to.

And about applications such as CRUSHERS, MILLS, SEPARATORS AND AGITATORS, that are typical heavy duty machinery whose drives are characterized by shock loads and dynamic displacement of large masses with big inertias. FLUID COUPLINGS for soft starting of the machinery, GEAR COUPLINGS for low speed shaft applications and ELECTROHYDRAULIC SERVICE BRAKES are typical products used for these applications.

News & Innovations


The NEW V317 Power Supply is smaller, lighter and able to control any DC electromagnetic brake within its maximum current range. V317 current output operates in a closed loop system that allows better performance control and faster response of electromagnetic brakes, making operation safer and more agile. V317 series power supplies are AC/DC drives with a fully digital control system to drive electromagnetic brakes. It is programmable to supply a call current for opening the brake, then an economy current to keep it opened.

Some features:
SUPPLY: From 3-phase alternating current from grid power or generator unit 220 … 480 V AC +/– 15 % – 50/60 Hz, insensitivity to phase sequence

Available with optional card. MODBUS protocol according to RS232-C standard and RS485 standard.

DISPLAY: Mounted to control board with 2 digit segmented alphanumeric and four LED status indicators.
