QPI’s Pit Stop Drum/ Pulley is a modular type drum system that can be used to create tail, snub, and drive configurations rapidly. With over 2,500 supplied and fitted nationwide.
Pit Stop Pulley Overview
Rapid Configuration Drum & Pulley Systems
QPI’s Pit Stop Drum / Pulley system is engineered to support rapid maintenance response and simplified conveyor pulley replacement across tail, snub and drive pulley applications.
The system provides the benefit of ‘off the shelf’ shaft ends that can be dispatched in the event of a bearing failure or can be held by sites on stock if down time is a critical factor.

Drum Types &
Specification Factors
Conveyor drum performance depends on pulley position, shaft arrangement, bearing selection, lagging suitability, conveyor duty and the manufacturing process behind each assembly.
Drum Types
Drive, Tail, Bend & Snub Pulleys
Conveyor drum selection should match the pulley position, belt tension, wrap angle, material loading and operating environment. Drive drums, tail drums, bend pulleys and snub pulleys each perform different roles within the conveyor system.
Position-Specific SelectionStandard Drums
External Bearing Drum Assemblies
Standard conveyor drums provide a proven solution for heavy-duty material handling applications, with external bearing arrangements, site-specific drum face widths, shaft configurations and lagging options available.
Standard Drum SupplyInternal Bearing Drums
Compact Conveyor Drum Design
Internal bearing drums are suited to restricted conveyor layouts where reduced external projection, cleaner guarding integration and compact installation are important operational requirements.
Compact Drum AssembliesShaft Options
Live, Dead, Stepped & Keyed Shafts
Shaft arrangements are specified around conveyor loading, torque transmission, bearing layout, pulley size and long-term operational reliability. Options can include live shafts, dead shafts, stepped shafts and keyed shaft configurations.
Shaft ConfigurationBearings
Dodge Bearing Support
Bearing selection is critical to drum performance, load capacity and service life. QPI can support conveyor drum assemblies using heavy-duty Dodge bearing arrangements where required for demanding industrial use.
Dodge Supplier SupportManufacturing Process
Built Around Conveyor Duty
Drum manufacture should account for shell construction, shaft fitment, welding quality, balancing, lagging compatibility, bearing selection and final inspection to support dependable conveyor operation in harsh environments.
