Series H4.56

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 H4.56 chain openable from both sides with crossbars every other link

1. Straight running due to inner/outer link design
2. Low-noise running due to built-in brake in the stop-dogs
3. The undercut design ensures very high rigidity and load capacity
4. 15% more tensile strength (compared to the best old E4 series), better unsupported length due to improved vertical stop-dogs
5. Openable crossbar available 450.X. Q
6. New interior separation system increases the service life of your cables by up to a factor of 4
7. "No camber" version possible simply by rotating the outer link; no rework required
8. Crossbars can be removed from both sides
9. Lid for e-tube can be opened and removed
10. Wide plastic crossbars – cable-friendly

H4.56 Series is suitable for the following types of applications:

Vertical: Hanging applications
Horizontal: Unsupported applications ≤ 5 m, gliding applications
Circular movement: Rotating applications possible, may require machining (machining rework is required from 180° rotation angle)

When to use Series H4.56

When a robust e-chain®/e-tube with 56mm inner height is required
If an inner width up to 600mm is required
For unsupported lengths up to 5.0m and fill weights up to 62kg/m
For travel lengths up to 400m
Also suitable for side-mounted, standing and hanging applications
Many modular options and accessories available

When not to use Series H4.56

When e-chain® is to be used in cleanrooms (ISO Class 1)
Series E6.52
When an extremely low vibration e-chain® is required
Series E6.52
If a compromise for more cost-effective price/stability can be made
Series 14040 , Series 14140 , Series 18840

* The required clearance height is HF = H + 50 mm (at 3 kg/m fill weight), which should be observed in all types of applications. Please contact us if you have particularly confined space requirements.
** The calculated length corresponds to the chain length without mounting brackets.

A=moving end, B=fixed end
Pitch: 91mm per link
Chain links per m: 11
Travel: S
Chain length = S/2 + K

Unsupported length

The unsupported length depends on 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
