The Flexible Expandable Gravity Roller Conveyor is a portable, non-powered conveyor designed for efficient carton and tote handling in warehouses, loading areas, logistics centers, and packaging operations. Its expandable scissor frame allows the conveyor to extend, retract, and curve according to changing material handling requirements.
With adjustable working height, swivel casters with brakes, multiple roller options, and a compact retractable design, this flexible roller conveyor is ideal for loading and unloading, temporary transfer lines, and warehouse areas where conveyor layouts frequently change.
Roller Diameter: 50 mm / 60 mm
Conveyor Width: 450 mm / 500 mm / 600 mm
Expansion Ratio: 1:3
Adjustable Height: 650–950 mm
Maximum Steering Angle: Up to 180°
Operation: Gravity / Manual
A flexible expandable gravity roller conveyor provides an adaptable alternative to permanently installed roller conveyor systems. Instead of using a fixed frame, it features a scissor-type expandable structure that allows the conveyor length and direction to be adjusted according to the working area.
Goods move across the freely rotating rollers by gravity or manual pushing, so no built-in motor or electrical drive system is required.
The conveyor consists mainly of an expandable scissor frame, conveying rollers, adjustable support legs, and swivel casters with brakes. It can be configured in straight or curved layouts and repositioned between different work areas, making it particularly suitable for warehouses, distribution centers, loading docks, and temporary material handling operations.
(Figure 1 Schematic diagram of the flexible expandable gravity roller conveyor – comparison of retracted and extended states)
The conveyor provides an expansion ratio of up to 1:3. It can be extended during operation to provide the required conveying distance and retracted into a compact footprint when not in use.
This makes the expandable roller conveyor especially useful in warehouses and loading areas where floor space needs to remain flexible.
Unlike a conventional fixed roller conveyor, the flexible frame can be adjusted to create straight or curved conveying routes.
With a maximum steering angle of up to 180°, the conveyor can adapt to changing warehouse layouts, workstations, loading positions, and temporary material handling routes.
The support legs provide a conventional height adjustment range of 650–950 mm.
The working height can therefore be adjusted to suit loading docks, packing stations, existing conveyors, and different material transfer points. The conveyor can also be configured horizontally or at an incline where appropriate.
Swivel casters allow operators to move and reposition the conveyor between work areas without permanent floor installation.
Once positioned, the caster brakes help secure the conveyor during operation. This makes it suitable for facilities where conveying equipment needs to be frequently deployed, moved, and stored.
Different roller configurations and materials are available according to the goods being handled.
Options include:
Single-row rollers
Double-row rollers
50 mm or 60 mm roller diameters
Galvanized carbon steel rollers
Stainless steel rollers
PVC rollers
Aluminum alloy rollers
Rubber-coated rollers
The appropriate roller configuration can be selected according to carton size, product weight, working environment, and handling requirements.
The flexible gravity roller conveyor can work independently or serve as a temporary connection between fixed conveyors, packing stations, sorting areas, and loading points.
Multiple conveyor sections can also be combined when longer conveying distances or more flexible layouts are required.

Best For | Loading, unloading and changing layouts | Permanent production lines |
A flexible expandable roller conveyor is generally more suitable when the conveying route, working position, or required conveyor length changes frequently.
Fixed roller conveyors are better suited to permanent production or material handling lines where the conveyor route remains unchanged.
The flexible expandable gravity roller conveyor is designed primarily for cartons, totes, boxes, and other goods with stable bottoms.
The conveyor can be extended toward loading docks, dispatch areas, or temporary loading points to reduce manual carrying distances during carton handling.
Its expandable design allows the conveyor to be positioned closer to truck trailers and container loading areas. After the operation is complete, the conveyor can be retracted and moved away to free up working space.
Use the conveyor as a flexible connection between sorting, temporary storage, packing, and dispatch areas where material flow changes throughout the day.
Expandable conveyors are suitable for e-commerce warehouses that experience changing order volumes and frequently adjusted packing or dispatch workflows.
The conveyor can provide temporary or auxiliary connections between workstations, packing areas, and existing conveyor equipment without requiring a permanent conveyor installation.
Choosing the right flexible expandable roller conveyor depends on several key factors:
Product Dimensions:
Consider the length and width of the cartons, totes, or boxes being conveyed. The bottom of the load should maintain stable contact with multiple rollers.
Product Weight:
Confirm the maximum weight of individual goods and the expected total load on the conveyor.
Required Conveyor Length:
Measure the distance between loading, unloading, packing, or transfer points to determine the required expanded length.
Conveyor Width:
Choose the conveyor width according to the dimensions of the goods. Common options include 450 mm, 500 mm, and 600 mm.
Working Height:
Consider the height of existing conveyors, workstations, loading docks, or other equipment that the flexible conveyor needs to connect with.
Roller Material:
Select galvanized steel, stainless steel, PVC, aluminum alloy, or rubber-coated rollers according to the goods and working environment.
Gravity or Powered Operation:
For manual or gravity-assisted carton handling, a flexible gravity roller conveyor provides a simple and economical solution. For continuous automatic conveying, a powered flexible roller conveyor may be more suitable.
Example: FA-50-500×4
FA – Single-row roller series
50 – Roller diameter
500 – Conveyor surface width
×4 – Four sections
Example: FB-50-800×5
FB – Double-row roller series
50 – Roller diameter
800 – Conveyor surface width
×5 – Five sections
For model selection, provide your required conveyor width, expanded length, working height, product dimensions, and load weight.
A flexible expandable roller conveyor is a movable conveyor with a scissor-type frame that allows its length and conveying direction to be adjusted. It can be extended during operation and retracted for compact storage.
It is primarily suitable for cartons, boxes, totes, and other products with flat and stable bottoms that can move smoothly across conveyor rollers.
No. This gravity model has no built-in motor. Products are moved by gravity or manual pushing, making the conveyor simple to operate and maintain.
Yes. The expandable and mobile design makes it suitable for temporary truck, warehouse, and loading dock material handling operations.
Yes. The conventional support height adjustment range is approximately 650–950 mm, allowing the conveyor to connect with different workstations and material handling equipment.
A gravity flexible conveyor relies on gravity or manual pushing to move goods. A powered flexible roller conveyor uses motorized rollers to provide continuous automatic product movement.
Different conveyor widths, roller diameters, roller materials, section quantities, and configurations can be selected according to product dimensions, load requirements, conveying distance, and working conditions.
