Return Roller
Lifting Cradles
Galvanised return roller lifting cradle systems designed to make return roller replacement safer, more controlled and more efficient across quarrying, aggregates and heavy-duty conveyor environments.
Return Roller Lifting Cradle Overview
Safer Return Roller Replacement Support
QPI’s return roller lifting cradles are designed to support safer and more efficient return roller replacement by keeping the roller supported during changeout and reducing the manual handling challenges associated with conventional return roller maintenance.
Suitable for single walkway and dual walkway access arrangements, the galvanised cradle system uses a pivoting mechanism locked by retaining bolt and can be operated using a standard spanner.

Roller Types &
Applications
Conveyor roller and frame specification depends on belt duty, loading conditions, material characteristics, return-side requirements, impact zones, frame compatibility and long-term maintenance access.
Standard Idlers
Carrying & Support Rollers
Standard idlers support the carrying side of the conveyor belt and are specified around belt width, load, troughing angle, frame layout and site duty. Correct idler selection supports tracking, belt stability and consistent material flow.
Core Belt SupportSpiral Returns
Self-Cleaning Return Support
Spiral return rollers are commonly used where material carryback and build-up need to be reduced on the return side of the belt. Their spiral form helps shed material and support cleaner belt return operation.
Return-Side CleaningRubber Disc Returns
Build-Up Resistant Return Rollers
Rubber disc return rollers are suited to return belt positions where sticky, wet or difficult materials may create build-up. Disc spacing helps minimise material accumulation and supports improved belt tracking.
Carryback ControlImpact Rollers
Loading Zone Belt Protection
Rubber impact rollers are used around loading and transfer points to help absorb shock loads, protect the conveyor belt and reduce stress on the supporting conveyor structure.
Impact AbsorptionSuspended Sets
Field Conveyor Roller Sets
Suspended roller sets can be used on field conveyors and longer conveyor runs where flexible belt support, ease of replacement and heavy-duty material handling performance are required.
Field Conveyor SupportUni Rollers
One Base Roller, Multiple Ends
Uni Rollers are designed around a versatile base roller format that can accommodate multiple terminal-end arrangements, helping reduce stockholding complexity and improve response for maintenance or breakdown replacement.
Stockholding EfficiencyRoller Construction
Shell, Shaft & Seal Options
Roller specification can include shell thickness options from 3.6mm to 12mm, shaft and bearing diameters from 20mm to 50mm, a 5-seal system and roller ends manufactured to suit existing conveyor frames.
3.6–12mm / 20–50mmFrames & Transoms
Alignment, Tracking & Support
Conveyor frames and transoms support roller alignment, belt tracking and structural stability. Options can include in-line and staggered layouts, self-cleaning cross members and slotted tracking fixings for adjustment.
Frame CompatibilityImpact Beds
Transfer Point Belt Support
Impact beds support the belt through high-load transfer points, helping reduce belt damage, improve material containment and protect the conveyor structure around loading zones.
