Conveyors calculator
Pallet Conveyor Capacity Calculator
Work out how many pallets the conveyor clears each hour once uptime and release losses are counted, then check that rate against the pallet flow shipping requires.
What this calculator does
- Good pallets per hour the conveyor clears after uptime and release losses, against the pallet flow shipping needs.
Formula used
- Gross capacity = usable pallet positions × transfer cycles per hour
- Good capacity = gross capacity × uptime ÷ 100 × release yield ÷ 100
- Capacity gap = required pallets per hour − good capacity
Inputs explained
- Usable Pallet Conveyor Positions: Powered positions on the pallet conveyor that can hold a pallet.
- Pallet Transfer Cycles per Hour: Transfer cycles each position completes per running hour.
- Pallet Conveyor Uptime: Run time ÷ scheduled time from the pallet conveyor downtime log.
- Successful Pallet Release Rate: Share of transfer cycles that release the pallet successfully.
- Required Pallets per Hour: Pallets per hour shipping needs from this conveyor.
How to use the result
- Best suited to checking pallet flow to shipping, sizing an end-of-line accumulator, justifying a conveyor upgrade.
- A steady average; peaks beyond the calculated rate will queue pallets. Mixed pallet sizes need the worst-case position count and cycle time.
Current U.S. benchmarks
- The U.S. has 21,668 machinery manufacturing establishments employing about 1,086,146 workers (Census County Business Patterns, 2023).
Common questions
- Why is good capacity below gross capacity? Uptime takes out the minutes the conveyor does not run, and the release rate takes out transfers that fail to clear. Both are measured losses, so good capacity is what shipping can count on.
- What counts as a pallet transfer cycle? One complete release of a pallet from a position to the next zone, including the sensor handshake and any stop retraction. A cycle that holds the pallet for a downstream machine still counts when it clears.
- How does accumulation affect this capacity? Holding pallets in powered zones consumes cycles without moving them toward shipping, so heavy accumulation lowers the rate the conveyor can deliver. Size accumulation for buffer time, not as storage.
- Should I use the palletizer's rated output? No, use transfer cycles measured on this conveyor. The palletizer rate is an upstream ceiling, and the conveyor's uptime and release success set what actually reaches shipping.
