A defined path above the floor.
An overhead conveyor moves suspended parts or carriers along a track through production, finishing, assembly or transfer areas. The purpose is to connect work steps while keeping useful access below.
Track, trolleys, carriers, supports and a method of movement work together. A powered chain may move connected loads; power & free allows designed independent carrier stops; a hand-pushed system uses manual movement.
Recognize the terms before comparing systems.
Some names describe the track and others describe how loads move. Enclosed track and I-beam identify construction; power & free identifies carrier control. Over-N-Under identifies an upper-and-lower closed-loop arrangement.
The selection guide explains the tradeoffs. Individual system pages show what needs to be checked for the application.
Where Overhead Conveyors Fit Best
Overhead conveyors are useful when the process needs a defined material path and the floor below has more valuable work to do. Typical applications include moving parts through paint or finishing processes, carrying assemblies between work areas, buffering production between operations, transporting fixtures, and keeping repetitive material flow out of forklift aisles.
If vertical lifting or broad hook coverage is the main task, compare a powered hoist monorail or bridge crane. An overhead conveyor follows a defined production path; it is not a substitute for every lifting or handling requirement.
What Has to Be Engineered
- Load and carrier: weight, dimensions, center of gravity, attachment points, carrier spacing, and the combined moving load.
- Route: pickup and drop-off points, turns, elevation changes, process zones, accumulation needs, and equipment clearances.
- Drive and take-up: chain pull, speed, duty, route friction, take-up travel, and service access.
- Support: building steel or freestanding structure, suspension method, column locations, deflection, bracing, and coordination with utilities.
- Controls and safety: starts, stops, process interfaces, switches, guarding, access, emergency devices, and the facility’s required risk review.
- Installation: staging, lifts, rigging, shutdowns, alignment, utilities, testing, commissioning, and startup support.
Installation and maintenance belong in the first layout.
The route needs practical support, access to the work and room to service the equipment. Define the installation scope while the layout can still change, and use the installed equipment documentation to plan maintenance.
Is an overhead conveyor the same as a monorail crane?
No. A conveyor normally moves suspended carriers through a repeatable production route. A monorail crane carries a hoist that lifts and positions a load along a runway. The track may look related, but the operating method, loading, controls, and design criteria are different.
Prepare a first discussion.
Bring the product and carrier dimensions, approximate weight, route, loading points, movement frequency or production rate, and available building information. Mark unknowns clearly. Existing-system photographs and equipment identification help establish the next review.
