As production levels grow and conveyors are pushed harder than ever, head pulleys find themselves under increasing strain. In WA's mining and resource industries, it's crucial that conveyors can handle higher loads, longer distances and heavier materials.
One of the most effective ways of ensuring operational efficiency is investing in a replacement head pulley. Promet is proud to facilitate conveyor pulley replacements across Australia, partnering with trusted suppliers to provide durable, fast and efficient units.

Why Head Pulley Capacity Matters
The head pulley is a conveyor's powerhouse. It transfers torque from the drive to the belt to enable constant material flow. When load demands rise, the head pulley must be built to withstand greater stress and torque.
If your business starts to experience a growth in production or heavier ore grades, you may find your pulley isn't rated for those conditions. That can result in:
-
Increased belt slippage and wear
-
Shaft or bearing failure
-
Excessive vibration
-
Reduced efficiency
-
Unexpected downtime
Once these signs emerge, it's worth considering an upgrade to a purpose built, higher capacity head pulley. That will ensure reliability under heavy loads and extend the life of your equipment.
Why You Should Replace, Not Refurbish
WA's mining environments require high performance and refurbished units often fail to meet those demands. They retain hidden structural weaknesses and their load ratings will remain limited by their original design.
That's why Promet specialises in delivering replacement pulleys engineered for modern load capacities. By replacing, you benefit from:
-
Higher Torque Handling: Precision balanced shafts and reinforced shells prevent deformation under stress
-
Reduced Slippage: We utilise advanced lagging materials to increase belt traction and ensure consistent power transfer
-
Longer Service Life: With brand new components you eliminate the risk of internal fatigue and misalignment
-
Lower Long Term Cost: Our units often cost less than full refurbishment
-
Improved Safety and Compliance: Promet Pulleys are built and tested to Australian standards, supporting site safety goals
Refurbishment might restore performance temporarily, but if the shell, shaft or bearings are already fatigued, full replacement is the most cost effective path.
Implementing Crowned Designs to Further Improve Belt Tracking
Operations with a particularly high load may choose to upgrade to a crowned head pulley. These have a slightly convex surface that helps centre the belt during operation. The belt naturally tracks inward toward the crown, reducing edgewear and alignment issues.
These are not required in every system, but crowned pulleys can improve stability when load distribution is uneven or tension varied. At Promet, we can supply replacement head pulleys with crowned profiles, paired
Customisable Lagging Solutions for High Load Conditions
Selecting the right lagging is crucial in managing traction and reducing slippage under heavy loads. We can pair head pulleys with one of four high traction lagging options, each suited to the unique needs of WA's mining environments:
-
Rubber Lagging: Diamond or chevron grooved surfaces for traction and self cleaning
-
Ceramic Lagging: Dimpled or hybrid designs for maximum grip on high tension belts
-
Polyurethane Lagging: For operations requiring chemical resistance
-
Flame Resistant Lagging: For coal and other combustible applications
Each surface is reinforced and can be applied via hot vulcanised or cold bonded methods.
