Spiral Conveyors

Spiral conveyors are a great solution to achieve vertical conveying of your product and are widely used in a wide range of industries and different types of spiral conveyors are available to meet the different  needs of different products and environments. Being vertical, spiral conveyors are a great solution where you have limited floor space.

Australis Engineering are proud to be the Australian representative of Taiwanese manufacturer, NEXUS. Nexus are the leading manufacturer of spiral conveyors in Asia with over 20 years experience and are committed to simplifying the operation and maintenance of their spiral conveyors through superior design and manufacturing processes that produce a high quality product.

Three types of Spiral Conveyors are available:

  • Unit Load Spiral Conveyor
  • Narrow Track Spiral Conveyor
  • Dual Track Spiral Conveyor

Why choose a NEXUS Spiral Conveyor?

 

NEXUS-logo_lrNexus spiral conveyors are your best choice due to:

Innovative design

Sometimes mechanical problems are complicated but the solutions are surprisingly simple. The combined experience of Australis and Nexus means we understand the customer’s requirements and expectations for a spiral conveyor system. Every day, on every spiral conveyor, Nexus seek to design a spiral conveyor solution to maximise the customer’s outcomes.

Easy Maintenance

Overload protection, chain over-length sensor, smart tension regulation device, automatic lubrication device etc, all these devices are integrated into Nexus spiral conveyors, so that even a low skilled machine operator can successfully complete basic maintenance work with the guidance of the Operations Manual. Nexus Spiral Conveyors also use a premium painting process that guarantees a high quality finish and makes maintenance easy and ensures improved hygiene.

Other accessories including rigid chain and high-quality bearing etc., ensures low- friction, durability, smooth operation and long life of Nexus spiral conveyors.

Low Noise

Operational noise is only 60dB (normal conversation is at 60-70dB), providing you a comfortable working environment.

Ease of Installation

The standard spiral conveyor is designed to perfectly fit into a container which helps reduce shipping time ex-Taiwan. The ready-to-run Conveyor can be shipped on a pallet; when arriving on site, it simply requires positioning (the weight of conveyor is so light that can be lifted by a hand pallet truck), levelling and electrical connection. The ease of installation saves you labour costs.

Customisation Service

The choice of colours, materials and the application of automated control systems for the conveyor are in your hands. Different kinds of flexible spiral conveyors can be customised to suit your exact requirements.

Unbeatable Value

Supplying spiral conveyors with high cost performance to our customers is our goal, we insist in an original design, use economical and robust materials and most effective methods of production to achieve cost-benefits, what NEXUS spiral conveyors help you to save is not only space, but also cost.

Unit Load Spiral Conveyors

NEXUS Unit load spiral conveyor, one of the most popular material handling spiral conveyors in the market, both in food and non-food industry, light-duty and heavy-duty conditions, it is proved to be effective.

Unit-Load-Spiral-Conveyor_lrThe Unit load spiral conveyor is equipped with 400 mm or 600 mm width slat chains, the other width can be also processed. To ensure the quality, all the slats chains are designed and produced by Nexus.

Features of the Unit Load Spiral Conveyor:

Flexible layout

The most common slat chain width of NEXUS unit load spiral conveyor is 400mm and 600mm, not more than 2000mm outer diameter, resulting in a wide range of applications for package handling.

Technical Data

  • Flexible layout.
  • Standard specification of slat chain is 420mm (available width is 400mm)and 620mm (available width is 600)
  • The maximum number of turns is 10.
  • Outer diameter of type 400 is 1,800mm. Outer diameter of type 600 is 2,000mm.
  • Because the inclination changes with height and number of layers, please contact us for further advice.
  • Inlet/outlet configurationSpiral-Conveyor-Configuration_lr

 

  • Speed: Maximum speed of the Unit Load Spiral Conveyors is 60m/min. Note an automatic lubricator should be installed to prolong the conveyor life when speed exceeds 35m/min.
  • Load capacity: The maximum load capacity depends on the tensile force on the transmission chain, and there are two kinds of transmission chain available, please refer the data in Brochure Tab.
  • Material: Spiral conveyors material: Mild steel painted / Stainless steel.  Transmission Chain material: Mild steel painted / Stainless steel
  • Low Maintenance Automatic lubrication device and chain over-length sensors are installed in each Unit Load Spiral Conveyor to minimise maintenance.
  • SEW motor as standard. Other brands available as an option.
  • A control box is not standard as we find  most clients need to integrated it into their whole material handling system, and they will do the electronic control systems themselves.
  • Frame. The frame is designed and made of stainless steel or mild steel painted (double-coated, primer + topcoat). These materials ensure that products are durable and have a long product life.

Slat chain

The slat chain is made from composite plastic material, which has the physical characteristics of high rigidity, high impact resistance and low friction. It can reduce the abrasion in the process of accumulation, as well as improving the stability and service life. Modular design simplify the work of maintenance and replacement.

Easy assembly

Without special tools or complicated procedure it can be assembled in transmission chain.

Hassle-free maintenance

Zigzag-type-slat-chain_lrModular design of the slat chain makes the replacement and maintenance as easy as playing Lego. You can purchase new slat chain from NEXUS to replace the old one; In the event of an emergency, you can also replace the worn parts (bearings and transmission chains) with same specification products as specified in our manual.

Outstanding load capacity and smooth operation

The Zigzag shape modules are of patented design: they interlace with each other and fit into the inter-space perfectly, avoiding interference caused by objects falling into the gap in operation. Load capacity is also enhanced because of the double-overlapping design.

Slat Chain with TPR (Rubber cover)

Zigzag-type-slat-chain-with-TPR_lr

  1. Rubber cover (TPR) with high friction coefficient can be added on surface of slat chain. It is advised to be used in upwards/downwards spiral conveyor with incline/decline angle exceed 37°.
  2. With low friction coefficient on the surface of plastic, incline angle for products made from  plastic,Iron and Aluminum should be less than 7.2° to insure the most steady conveying.
  3. For cartons and other products with PE film, the incline angle should be less than 11.5°.
  4. Once the speed exceed 45M/min, the incline angle should be reduced 5% for each 5M/min acceleration.
  5. In special high/low temperature environment, rubber cover (TPR) is not available for use.
