Conveyor Roller Maintenance Using a Hydraulic Puller for Mining Applications

A mining customer required a safe and efficient method to remove large pulley hubs from a conveyor system. A hydraulic puller solution was used to extract the hubs quickly and safely, minimizing downtime and supporting continued conveyor operation.

A customer operating a conveyor system in a mining application needed to remove two large pulley hubs as part of planned maintenance. The removal process required a controlled pulling solution capable of handling large components safely.

Pulley hubs in mining conveyors are large, tightly fitted, and difficult to remove using conventional methods. Improper removal techniques can result in equipment damage, extended downtime, or safety risks to maintenance personnel.

A hydraulic pulling solution was selected using the PTHT-200T hydraulic puller. The puller provided controlled, high-force pulling capability, allowing the pulley hubs to be removed safely and efficiently from the conveyor system. This type of conveyor maintenance challenge is solved using hydraulic pullers that apply even, controlled force to remove large press-fit components without damaging surrounding equipment.

By using the hydraulic puller solution, The customer was able to complete the pulley hub removal efficiently and return the conveyor to operation quickly. The approach avoided costly downtime while promoting safer maintenance practices. Based on typical conveyor maintenance and hydraulic assistance applications, the solution delivered measurable operational benefits:
•    Maintenance Time Reduction: Hydraulic assistance typically reduces roller removal and installation time by approximately 20–35% compared to manual methods.
•    Downtime Reduction: Faster roller replacement shortens maintenance windows, helping reduce overall conveyor downtime.
•    Labor Efficiency: Reduced manual handling lowers physical effort and can reduce labor hours per maintenance event by an estimated 10–25%.
•    Safety Improvement: Controlled lifting and reduced manual handling lower the risk of strain and pinch-point injuries.
•    Maintenance Consistency: Repeatable hydraulic methods improve consistency across maintenance crews and shifts.
