What is flexible expandable conveyor?

Flexible expandable conveyor is used to solve problems on transport in such complicated environment as warehousing, packing line and loading/ unloading etc, and can handle all sizes of boxed packages with flat bottom. 

It has an advantage over fixed conveyors in flexibility and movability. It makes skillful use of movement, expansion and compaction so that floor space required can be reduced remarkably.

This conveyor is a complete steel structure, with flexibility. And it can be laid out at your request.

Multiple flexible expandable conveyors can be connected together and can be expanded optionally to any length required.

Load Capacity

When complete expanding, load capacity per unit ( between support legs) is no more than 100kg ( in the state of no impact load.)


4" heavy-duty swivel castors are used. On two ends of flexible expandable conveyor, castors with brake are provided. They stand firmly when handling packages.
