Spiral Curve Belt Conveyor

Spiral Curve Belt Conveyor

Conveyor function is NOT affected by fluctuation: in the environment or loading,Precise belt tensioning and alignment of the end pulleys NOT required,Beft contamination does NOT cause loss of drive traction.



No Substitute for Reliability

• Conveyor function is NOT affected by fluctuation: in the environment or loading
• Precise belt tensioning and alignment of the end pulleys NOT required
• Belt contamination does NOT cause loss of drive traction

Exquisite processing technology

• High speed capability
• Low noise operation
• Easy to maintain
• Low Lifetime cost
• Practical design
• Wide conveying widths available
• Low belt tension for long component life
• Positive drive belt system means no end roll slip
• Custom designed for your specific application


Powertrain system: #50 conveyor chain with belt attachment links.
Belt: 2-ply Black PVC-OP with #1A Clipper lacing.
Sideguards: Standard sideguards are rolled using 3 mm steel. Sideguards over 150 mm high have a 25 mm angled out top flange.
Paint:Epoxy powder coating in RAL colors is standard. Color matching is available.
Drives: A wide range SEW, Nord are available. You can purchase the gear motor separately.
Available Sizes: Custom-built for a particular application. We frequently builds curves with a special radius. Arcs as large as 350 degrees are readily available. Arcs as low as 5 degrees are available, but are dependent on the outside radius size.

Model Designations A typical model is written as follows: 700M500-90, 700 is the inside radius dimension to the frame.

Specification example

M indicates it is a metric model with a 216 mm frame 500 is the conveying width between sideguards 90 is the degree of angle.

Frame height is indicated in the model designation as follows: M indicates a 216 mm high Mid-Frame model.

HM indicates a 305 mm high High-Frame model The model designation does not indicate the direction of travel.


Rendo can manufacture special sizes to meet customer requirements.

Rendo chain/belt system is a simple concept, but is not easy to build. Our efforts toward perfection results in a quiet and efficient conveyor that is very reliable and easy to maintain.

High performance is only achieved by using high quality, modern materials and precision manufacturing.

We have invested heavily in automated fabrication equipment and quality manufacturing systems to achieve the highest precision and shortest production time.
