HS Code: 842839900
In modern logistics conveying systems, achieving smooth, efficient, and flexible material transfer is key to enhancing overall efficiency. The CR220 Double Sprocket Driven Curved Roller Conveyor is an exceptional product designed precisely for this purpose. It perfectly combines powerful drive performance with flexible layout capabilities, is optimized for handling unitized packaging materials such as boxes, cartons, and pallets, and is an ideal choice for connecting different processes and achieving efficient space utilization.
Product Overview
The CR220 Double Sprocket Driven Curved Roller Conveyor is a heavy-duty, high-performance conveying equipment. Its core feature lies in the dual sprocket and dual-chain series drive method, which synchronously transmits power through the sprockets at both ends of the rollers, ensuring powerful and stable conveyance even on curved sections. This model can be easily integrated into complex conveyor line layouts, demonstrating irreplaceable advantages particularly at direction-changing nodes, such as 45°, 60°, 90°, 120°, or even 180° curves.
High Conveying Capacity: The dual-chain synchronous drive provides torque and traction far exceeding that of single-chain drives, enabling it to easily carry and convey heavy boxes and fully loaded pallets, meeting the demands of high-intensity, high-load operations.
Extremely Stable Operation: The dual-chain structure effectively balances the driving force, avoiding issues like misalignment or jamming that can occur with single-side drives. The synchronized rotation of the rollers ensures smooth transition of materials on curves, effectively protecting the materials' appearance and reducing damage.
This machine is specifically designed for curved conveying. It can be customized with various turning angles (45°, 60°, 90°, 120°, 180°, etc.), perfectly adapting to your factory's spatial layout. It enables continuous, seamless directional change of materials, eliminating the need for transfer platforms and additional power units, thereby simplifying the system structure.
Thanks to its precise drive design, this conveyor enables stable, synchronous flow of materials within the curve. This is crucial for production and sorting systems that require maintaining material orientation consistency or orderly accumulation, avoiding confusion and collisions caused by speed differences at turns.
Constructed with a robust steel frame and high-quality sprockets and rollers, the equipment is durable and capable of adapting to various harsh industrial environments. Its drive system design is mature and reliable, with simple maintenance, effectively reducing long-term operating and maintenance costs.
Double-row sprocket driven roller conveyor is applicable to delivery of box, case or pallet packed materials and transport in an certain angle like 45°, 60°, 90°, 120° or 180°.
Logistics Distribution Centers: For directional change and conveyance of box/case goods between sorting areas and inbound/outbound areas.
Manufacturing Production Lines: Connecting assembly stations in different orientations to achieve automated flow of components or finished products.
Warehousing Systems: Serving as a link between automated storage and retrieval systems (AS/RS) and loading/unloading docks, handling the curved conveyance of standard palletized goods.
Express Parcel Sorting: Integrated into automated sorting lines, guiding parcels to designated loading or palletizing areas.
