Product Overview

Gravity roller conveyor is a non-powered, cost-efficient material handling solution that relies on the gravitational force of goods to achieve automatic sliding along an inclined track. Composed of freely rotating rollers mounted on a fixed frame, it requires no motor drive and delivers smooth conveyance for flat-bottomed unit loads such as cartons, plastic totes, turnover boxes and light pallets.

Featuring a simple modular structure, flexible layout and zero energy consumption, it can be freely spliced into straight lines, curves and split paths, and is widely used for short-distance transfer, temporary buffering, manual picking assistance and loading/unloading docking. It is an ideal choice for scenarios pursuing low investment, quick deployment and maintenance-free operation, and can be flexibly matched with powered conveyor lines, sorting systems and warehouse workstations.

Typical Application Scenarios

01/

Warehouse Loading & Unloading Docks: Telescopic and fixed gravity roller conveyors are installed between the truck compartment and the warehouse platform to realize fast sliding transfer of cartons and totes, eliminating manual carrying distance and significantly improving loading and unloading efficiency.

02/

Order Picking & Sorting Buffer Zones: Inclined gravity roller lines are arranged behind the picking workstations. Picked goods slide to the sorting area automatically by gravity, realizing queuing and temporary storage of orders without power, which is suitable for e-commerce and retail distribution centers.

03/

Production Line Workstation Connection: Gravity roller tables are set between adjacent assembly processes, so that workpieces can be transferred to the next station by self-weight after processing, realizing beat-type circulation of materials and reducing redundant handling actions.

04/

Carton & Tote Temporary Storage Areas: Multi-section parallel gravity roller racks are used as first-in-first-out (FIFO) buffer storage. Goods are replenished from the high end and taken from the low end, which is suitable for material turnover of small parts and semi-finished products.

05/

Food & Light Industry Workshops: Stainless steel gravity roller conveyors are used for finished product transfer and packaging line docking in clean workshops. They are resistant to water washing and corrosion, meet hygiene requirements and have no risk of oil pollution from power devices.

06/

Pallet Circulation & Staging Areas: Heavy-duty gravity roller sections are applied for empty pallet storage and short-distance transfer. Pallets slide in sequence under gravity, cooperating with forklift operation to optimize the logistics rhythm of the pallet yard.
