How to choose
1. Item Size
Measure the dimensions (length x width) and weight of the largest and smallest items to be carried on the conveyor. To ensure there are three rollers under the item at all times for stability, the item length should be more than 160mm. Speak to Sitecraft about specials.
2. Frame width and length
Choose the frame width closest to the item. Items can overhang the conveyor by a small amount, but for safety reasons overhang should be minimal. Plan the number of frame sections (straight and/or curved) based on the distance the items are to be moved.
3. Roller type
The weight of the items to be carried determines the type of roller.
PVC rollers (25kg (55lb) capacity) have a plastic bearing and are liable to be damaged if loads are dropped onto them. Steel rollers (100kg (220lb) capacity) have a steel swaged bearing. Calculate the number of rollers (19 per curve/1500mm (5') straight section) required.
4. Stand type
If the conveyor is to be permanently located, then RHS stands should be chosen, and only one stand per join will be necessary. If the conveyor is likely to be moved, then the flexibility of pipe stands should be considered, and each frame should have two stands.
