Series 3500

Here you can configure your e-chain system® individually. All entries and changes are taking over to the part list which is situated at the end of the page.

Series 3500 – chain, snap-open along outer radius

1. Optimised opening system for fast opening of the crossbars, either from the left or right
2. Glide surfaces on the side for side-mounted operation
3. Semi-enclosed e-tube Series 3450
4. Proven and-tested mounting bracket
5. Series 3400 and 3450 snap-open along inner radius
6. Strain relief can be integrated in the mounting bracket
7. Double stop system for long unsupported lengths
8. High holding force of the crossbars
9. Enclosed e-tube Series 3480
10. Flexible modular interior separation system
11. Easy assembly due to optimised pins
12. Also available as ESD version
13. Strain relief separator - Separator with integrated strain relief

Available inner widths Bi: 50 to 250 mm
Available bend radii R: 75 to 300 mm
Pitch: 67 mm/link = 15 links/m

Series 3500 is suitable for the following types of applications:

Vertical: hanging applications ≤ 80 m, standing applications ≤ 3,0 m
horizontal: unsupported applications ≤ 3 m, gliding applications ≤ 150 m
rotary: rotating applications may be possible, please contact us

When to use Series 3500

When a medium-sized, strong system (e-chains®, half e-tubes, completely enclosed e-tubes) with 45 mm inner height is required
If an inner width up to 250 mm is required
For unsupported lengths up to 3,0 m and fill weights up to 13 kg/m
If an opening system is required to quickly open from either the left or right

When not to use Series 3500

If max. stability is required
System E4.1, Series E4.42
For very easy applications
easy chain®, E300

* The required clearance height is HF = H + 40 mm (with 2.5 kg/m fill weight), this should be taken into account for all application types. Please contact us if you have particularly confined space requirements.
** The calculated length corresponds to the chain length without mounting brackets.

Pitch: 67 mm
Chain links per m: 15
Travel: S
Chain length = S/2 + K

Unsupported length

Unsupported length versus fill weight
X axis: Unsupported length in m FLB/FLG
Y axis: Fill weight in kg/m
Lower scale: Travel S in m
FLB = Unsupported with permissible sag
FLG = Unsupported with straight upper run

Reference example A:
Fill weight = 2 [kg/m]
Unsupported length FLB = 2,5 m
Travel = 5,0 m
