Vertical Spiral Conveyor Factory for Boxes and Cartons

The AstraRoll Technical Advantage: Continuous & Compact
Moving square boxes up a curved incline requires precise engineering to prevent jamming and product slippage. We designed our spiral series for absolute reliability:

High-Friction Polymer Slats: When moving up a spiral, smooth plastic boxes or glossy cardboard cartons will slide backward. Our overlapping POM chain slats are embedded with specialized high-friction rubber inserts. This guarantees that your cartons lock into place and maintain their exact spacing from bottom to top without slipping.

Continuous High-Throughput: Unlike VRCs (Vertical Reciprocating Conveyors) that must wait for a platform to go up, unload, and come back down, our spiral runs continuously. It can handle up to 3,000+ cartons per hour, acting as a massive buffer zone while bridging elevation changes.

Low-Tension Drive Technology: Standard curves create immense chain tension, requiring multiple motors. AstraRoll utilizes precision guide bearings along the inner track. This converts sliding friction into rolling friction, allowing us to power massive 10-meter-tall spirals with just one highly efficient gear motor.

Ultra-Compact Footprint): A standard 3-meter elevation change requires nearly 15 meters of straight floor space using a traditional incline conveyor. The AstraRoll Spiral achieves the same elevation in a circular footprint of less than 2.5 x 2.5 meters.

Key Specifications & Custom Capabilities

Please note: Every spiral conveyor is custom-engineered to your facility's layout and payload requirements.

Elevation Height: Custom built from 1 meter up to 10+ meters.
Belt Widths: 300mm to 1000mm.
Conveying Speed: Adjustable up to 60 meters per minute (approx. 200 ft/min).
Load Capacity: Up to 50 kg per linear meter (Continuous dynamic loading).
Frame Construction: Powder-Coated Mild Steel (Standard Warehouse) or 304 Stainless Steel (Food & Beverage / Washdown environments).

Why Choose AstraRoll? (Your Automation OEM Partner)

1. Drop-In Line Integration

We don't just sell you a tower; we ensure it works with your line. We precisely engineer the tangential infeed and outfeed extensions so that your existing horizontal belt or roller conveyors feed cartons into the spiral seamlessly, without "dead zones" or box-crashing.

2. Factory-Direct Modular Construction

Importing complete automation systems can be costly. AstraRoll spirals are manufactured modularly at our facility, fully assembled and tested for 48 hours, and then carefully split into shipping-friendly modules. This ensures affordable global logistics and rapid, bolt-together installation on your factory floor.

Frequently Asked Questions (FAQs)

Q: Can one spiral handle different sizes of boxes at the same time?
A: Yes. Unlike gripping elevators that must be adjusted for specific carton sizes, the spiral conveyor acts just like a standard flat belt. As long as the cartons fit within the track width, you can mix small boxes, large cartons, and plastic totes on the same line simultaneously.

Q: What maintenance is required for the spiral chain?
A: Maintenance is minimal. Our side-flexing chains run on precision sealed bearings and use self-lubricating wear strips. The primary maintenance is periodic visual inspection, chain tensioning (which is easily adjustable), and ensuring the track remains free of severe debris.

Q: Do you provide the control systems (PLC/VFD)?
A: We supply the spiral equipped with the premium gear motor. We can either provide a standalone control cabinet with a VFD (for independent speed control and emergency stops) or wire the motor directly to a junction box so your integration team can tie it seamlessly into your master PLC.

Q: Can the conveyor run in reverse?
A: Yes, our reversible spiral option allows the same unit to act as an elevator during loading shifts and a descender during shipping shifts, doubling its utility for your warehouse.

Q1. Are you a trader or direct factory?

We are a direct manufacturing factory with over 20 years of expertise in high-end industrial rollers, casters and material handling solutions. Our facility operates with ISO-certified quality management systems, allowing us to maintain full control over production cycles and quality standards. Throughout two decades of growth, we have established deep, long-term strategic partnerships with several listed companies and global automation leaders, proving our reliability as a high-tier industrial supplier.

Q2. What are your main products?

AstraRoll specializes in the engineering and production of three core product lines: Industrial Rollers, Heavy-Duty Wheels, and Precision Casters. We do not just sell components; we provide integrated movement and transport solutions. Our products are widely utilized across high-demand sectors, including: New Energy, Lithium Battery, Mining, Heavy Industry, Medical Institutional, Agriculture and Logistics.

Q3. What about delivery time?

We deeply understand that project timelines are critical.
Standard Products: Usually dispatched within 7–15 working days if the components are in stock.
Customized/OEM Orders: Depending on the complexity and volume, the lead time typically ranges from 20–35 days. This includes time for technical drawing confirmation, specialized tooling, and rigorous pre-shipment testing.
Shipping Methods: We offer flexible global logistics solutions, including FOB and CIF terms. We ship via Sea Freight (for bulk industrial orders), Air Freight (for urgent project needs), and International Express (DHL/FedEx/TNT) for smaller components or samples.
