====================================================

A telescopic conveyor would require huge roller rack carriages which are and

would be required to be integral rather than internal due to the return idlers and the required two tail pulleys at the end of each extension point as you would need a second passive snubber pulley and training idler to safely pass the belting to the next extended length in my opinion.

the bottom carcass will wear out much sooner as well if it is simply dragged.

The only stacking conveyors I have seen or worked on have a pair of hydraulic cylinders connected to the stacker carriage and used to increase its height for stacking which gives you elevation with much less trouble than a squirt design conveyor.

In coal mining horizontal squirt/extendable conveyors have a belt storage magazine that threads all the available belting under tension, using snubber pullies and you may have patent infringemernt issues with Joy Global/Continental Conveying "only in my opinion".

The issue is one of opportunity cost, physical laws, finished product size and tonnage per hour.

A telescoping conveyor is only as good as the materials ability to be conveyed and its angle of repose because you are dealing with gravity and that is always the primary issue as it will always try to fall back upon itself. ■
