Shipped recently was a gravity conveyor system with some special features.
Gravity conveyors are the most popular and lowest cost conveyors available, but are capable of great versatility in the right situations and applications.
This particular conveyor was for a special pallet handling area where the product being conveyed was oily.
It's not common to have a pallet conveying application where the product is covered in oil type deposits but in this case a few special amendments had to be made to the conveyor.
First, the rollers were made from stainless steel, as the particular oil here was corrosive to mild steel.
The fasteners for the rollers also has to be stainless just in case the oil made direct contact with them. We possibly could have used plated screws but decided to use stainless to be sure.
The pallets had to overhang the conveyor for operational reasons, so the side frames of the conveyor were dropped below the rollers.
The paint finish was powder coated, again for the purposes of corrosion resistance.
Finally, there was a fabricated drip tray under the rollers to pool the residual oil and allow it to drain away in a controlled manner.
