● Speed

Maximum speed of our spiral conveyor is 60m/min, automatic lubricator should be installed to prolong the product’s life when speed exceeds 35m/min.

● Load capacity

The maximum load capacity of narrow track spiral conveyor depends on the tensile force of transmission chain, and there are two kinds of transmission chain for choice:

Mild steel transmission chain, Max. load capacity is 50kg/Meter
Stainless steel transmission chain, Max. load capacity is 40kg/Meter

● Material

Spiral conveyors material: Mild steel painted / Stainless steel

Transmission Chain material: Mild steel painted / Stainless steel

● Color

Nexus classic color of spiral conveyor (Highly recommend)

If you choose mild steel as material of your spiral conveyor, and the above optional color solution is not suitable for you, under this case, a standard color appointed by you will be necessary for painting work.

Please refer to RAL KT table as below to confirm which color you prefer:

Note: Different computer’s monitors may lead to a difference in color tones, if a specific color tone is required, please send us the specific color sample by post

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.

All slat chains of NEXUS Narrow track spiral conveyors are designed and produced by NEXUS to ensure the top quality and competitively price.

Friction rubber cover(TPR) can be added on surface of slat chain depends on the inclined angle and loads.

Incline angle advice
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 exceeds 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.
