Rigid and flexible couplings for mechanical drives

Vulkan offers a range of couplings for mechanical drives, including torsionally highly flexible couplings, jaw couplings, tyre couplings, gear couplings and disc couplings with different levels of stiffness, depending on the result to be achieved.

Our rigid couplings transmit synchronous torque values with high axial displacement capacity and are best for working in aggressive environments and on applications subjected to frequent motion inversion.

Flexible couplings absorb shock loads and vibrations deriving from either driving or driven equipment, are easy to install and are maintenance free. This makes them well-suited for heavy-duty applications. The typical claws design guarantees the possibility to transmit the motion, even if the elastic element might be damaged.

Hydrodynamic couplings for mining applications

Highly flexible couplings transmit definite torque values with high elasticity, making them ideal for applications subjected to torsional vibrations.

Our hydrodynamic couplings are specifically designed for mills, conveyor belts, fans and all machinery with proper high inertia. They provide smooth engaging and disengaging of the motion, overload protection for driving and driven machinery, and variable torque transmission capacity ranging from 80% to 270% of the operating torque.

Brakes for conveyor belts and cranes

Vulkan provide pneumatic brakes, electromagnetic brakes, electrohydraulic brakes and hydraulic brakes for applications including conveyor belts, hoist and gantry cranes. The drum brakes line (electromagnetic or electrohydraulic) is ideal for heavy-duty applications used in the mining industry.

Our 100% in-house production allows us to customise all products according to individual requests.

Backstops, freewheels and electromechanical actuators

We offer both high and low-speed backstops and freewheels for conveyor belts, elevators, cranes, velocity reducers and pumps used in the mining industry.

Vulkan electromechanical actuators are developed to activate silo gates, raw material gauges, ventilators, cranes’ mechanical locks, loaders, and paper and pulp-making machines. These actuators bear applications from 30kg to 4,000kg at varied speeds, position sensor and easy-to-adjust overload.

Industrial clutches and rail clamps

Vulkan industrial clutches are designed for specific installation on PTOs, mainly used in the actuation of machinery that requires operation interruption without needing to stop the driving equipment. This equipment may include cranes, hoists, compressors and fans, etc.

Our rail clamps allow you to provide safer clamping of loaders and unloaders, ore stackers and recliners, locomotives, overhead cranes, and gantries.

Anti-vibration mounts for power generation

Vulkan anti-vibration mounts use rubber dampers to isolate vibration from machinery such as propulsive engines (diesel and electric), generator sets, pumps, compressors and any accessory that requires significant structural-borne noise isolation.

Our rubber dampers are specifically manufactured to isolate the supported machine from external forces such as shock excitations, while damping vibrations produced by the machine itself.
