Takeup Travel Distance

The take-up stroke or movement depends on a number factors including Belt Elastic Elongation, Permanent Belt Stretch and Initial Belt stretch. The following table gives a guideline on take-up travel distances which should be allowed:

Screw or Manual Take-up

Minimum Take-up Travel in % of Centre Distance
	Fastened joints		Vulcanised Splices
Operating Tension	100% of RatedTension	75% of RatedTension	100% of RatedTension	75% of RatedTension
Belt Type
All Fabric Belts	1.5%	1%	4%	3%

Automatic or Gravity Take-up

Minimum Take-up Travel in % of Centre Distance
	Fastened joints		Vulcanised Splices
Operating Tension	100% of RatedTension	75% of RatedTension	100% of RatedTension	75% of RatedTension
Belt Type
Fabric - Cotton Fibre	1.5%	1%	4%	3%
Fabric - Cotton / Nylon		1.5%	2.5% + 0.65m	2% + 0.65m
Fabric - Rayon / Nylon	1%	1%	1.5% + 0.65m	1% + 0.65m
Fabric - Nylon	2%	1.5%	2.5% + 0.65m	2.5% + 0.65m
Steel Cable	-	-	0.25% + SpliceLength	0.25% + SpliceLength

Note: These distances are for normal conveyors where the Drive is at or close to the discharge end of the conveyor. For conveyors with drives located close to the loading end or regenerative conveyors a proper dynamic analysis should be performed to determine actual takeup travel.

You can refer to the Tension Calculation Reports for details of the take-up movement due to Elastic Elongation of the belt due to tension changes between stationary and operating conditions.

For more detailed instructions refer to the Input Takeup details help topic.
