Spiral Conveyors
Gravity Roller Spiral Conveyor
Unpowered rollers set along a spiral track, carrying rigid goods downwards without a drive and without power.
The machine
Goods travel down the rollers under their own weight.
It is not the machine for goods that have to go up, or for a descent that has to be driven and speed-controlled.
Best suited for
- Moving cartons, plastic crates, boxes and other rigid packaging downwards
- High-rise buildings, and any descent where a driven spiral would spend power on what gravity does
-
On site
A gravity roller spiral installed and running.
-
Unpowered rollers
Rollers set along the spiral track. Goods travel down them without a drive.
Technical data
Specifications and options
Confirm every figure against your application.
Specifications
- Direction
- Downwards only
- Drive
- None. Unpowered rollers along the spiral, with no power consumption
- Sizing
- Outer diameter, number of layers and incline angle are designed to the product size and the space available Track width and number of layers are customised.
- Braking
- Products move to the outer side and rub against the HDPE side guard, which slows them An additional brake device is generally not needed.
- Frame
- Painted mild steel as standard; stainless steel on request For mild steel, the paint colour is specified by RAL.
- Side guard
- 10 mm HDPE on the side guard, acting as a friction-resistant protective wall
- Multi-entry
- Available, using sensors and other electronic controls On request.
- Maintenance
- Simple and regular maintenance only, because the frame structure is simplified
Roller types
- Single-row free roller
- The standard type. Products slide down against the outer side guard, so they do not stay in the centre of the track
- Multi-row free roller
- Not the standard type. Products move in a circular motion and slide down within the centre of the track Products descend at high speed: NEXUS states that this type is not suitable for fragile products.
