Mining - extreme challenges for people and machines
The extraction of raw materials is one of the most demanding industrial fields of application worldwide. Whether in open-cast mines, underground mines or mobile processing plants – machines and components in the mining sector are exposed to extreme loads on a daily basis.
In the harsh and dusty environment of mining, machine components are exposed to extreme loads – high lateral forces, vibrations, shock loads and abrasive particles are the order of the day. This is precisely where Overhung Load Adaptors (OHLAs) from Zero-Max, for example, offer a crucial protection and performance component.
Harsh environmental conditions
Challenge:
Dust, moisture and extreme temperatures have a massive impact on seals, bearings and gearboxes.
Zero-Max Solution:
Overhung Load Adaptors (OHLA) with sealed, large-dimensioned bearings protect sensitive drives from dirt, water and mechanical overload.
Benefit:
Extended service life of pumps, gearboxes and bearings – less maintenance, lower failure rate.
Continuous mechanical load
Challenge:
Systems run in continuous operation with high torques, impact loads and changing operating conditions.
Zero-Max Solution:
CD®-Couplings (Composite Disc Couplings) transmit high torques backlash-free and are at the same time torsionally stiff and maintenance-free.
Torq-Tender® Safety Couplings reliably protect against sudden jams and overload situations.
Benefit:
Protects the drive chain against mechanical damage – fast-reacting, low-wear and reliable in continuous use.
Maintenance intensive locations
Challenge:
Spare parts and maintenance are time-consuming and expensive in decentralized mining locations.
Zero-Max Solution:
OHLA and CD-Couplings are maintenance-free and designed for long-term operation.
Adjustable Speed Drives enable easy mechanical speed control without electronics – ideal for regions with an unstable power supply.
Benefit:
Minimized maintenance, no lubricant change, simple installation – maximum availability with minimum support.
Economic pressure
Challenge:
Downtimes cause high costs – every component must function reliably.
Zero-Max Solution:
Robust OHLA´s take the load off critical components such as hydraulic pumps or motor shafts.
Torque Limiter Torq-Tender® disengages exactly to the defined torque in the event of overload – prevents expensive consequential damage.
Modular couplings can be quickly exchanged and tailored to specific requirements.
Benefit:
Increased operational reliability, predictable maintenance, low life cycle costs – Zero-Max protects your system before damage occurs.
Overhung Load Adaptor (Outrigger Bearing Assembly) for Mining
Powerful in harsh environments
Whether dust, slurry, vibration or extreme temperature differences – OHLAs have been specially developed for continuous operation in harsh industrial environments. Robust bearings, integrated sealing systems, and optional customized flange connections make them the ideal addition to stationary and mobile mining applications.
Protection for bearings and drive systems
OHLAs absorb external radial and axial loads that would otherwise act directly on pump or gearbox bearings. They therefore protect sensitive components and extend the service life of drives such as:
- Hydraulic pumps
- Gear motors
- Screw Conveyors / Auger Conveyors
- Vibration screens
- Belt Conveyors
Robust design for extreme operating conditions
- Sealed bearings for maximum service life in dirty environments (e.g. ore transportation or crushing plants)
- Large dimensioned bearing to support high combined loads
- Customizable mounting flanges for flexible integration into OEM systems
- Shifting the load point from the motor mount to the robust OHLA mount
- Integrated contamination barrier offers protection against contamination
Typical applications in the mining sector
- Mobile heat exchanger
- Conveyor belt systems and idlers / pulleys
- Rock crusher / pulverizer
- Mobile bucket wheel excavation
- Crushing and screening systems
- Drilling equipment, tracked vehicles
- Mobile heating systems
- Pump units for slurry applications
Advantages at a glance
- Extended service life of gearboxes and pumps
- Protection against axial and radial loads
- Lower maintenance costs due to external support of the load
- Compact design for easy integration into mobile and stationary mining systems
- Designed for continuous operation under vibration, dirt and high load changes
Composite disc couplings for mining - maintenance-free, robust and powerful
In the mining industry, power transmission components are exposed to extreme loads: dust, vibration, high torques and continuous operation are part of everyday life. Composite disc couplings from Zero-Max have been specially developed for these harsh operating conditions. They transmit torques reliably and without backlash – without lubrication and with minimal maintenance.
The fiber-reinforced composite discs offer high torsional stiffness combined with good shock absorption. Even in the event of misalignment, the coupling remains reliable and protects connected motors, gearboxes and pumps from overload. With their compact, corrosion-resistant design, CD couplings are ideal for conveyor systems, crushers, pump systems and mobile processing machines.
Advantages at a glance:
- Maintenance-free & durable – no need to change lubricant
- High torque capacity in a compact design
- Resistant to dust, moisture and shocks
- Ideal for misalignments and dynamic loads
- Temperature and corrosion-resistant for the harshest environments
