The
load, stroke and speed parameters are nominal values only
and must not be exceeded when they are all applied together
at their maximum values. In an application where one of
the parameters is lower, some of the others may be increased.
It is vital to consult us in applications where values
exceed those shown above.
* For the LinkLift R version,
the maximum parameters are not cumulables.

Linklift chains
are completely enclosed in a steel magazine attached to
the drive housing.
The chains are thus protected during installation and
storage. Depending on the space available, the standard
length of LinkLift magazines was designed in accordance
with the length of stroke, you
can download drawings.
These magazines may be made-to-measure to suit the space
available.
Please consult
us for additional information. |
|
Direction of shafts :
|
|
Select the direction
for output of the shaft from the housing, position A
or B, or a double shaft output A+B.
|
 A |
B
|
|
Standard options :
- Reduction gear flange : allows
attachment of a reduction gear directly onto the drive
housing.
- Splined shaft : combined with
the flange option above, this allows a non-coupling
link with the reduction gear.
- Special length shaft : the
shaft is keyed, with a maximum length of 500mm, depending
on the transmission system selected.
- Double shaft output : this
option allows the coupling of 2 systems with a remote
motor drive.

How to
design a LinkLift system :
- Check the characteristics you require
correspond to the design characteristics of the product
e.g. load and stroke.
- Check that the total stroke includes
the usable stroke + neutral stroke + adjustment stroke.
- Define the type of magazine with
the result of the question 2
- Indicate the direction of the shaft
: A or B
- Indicate the options e.g. special
shaft or reducing gear attachment flange, etc. and
attach a drawing if possible
Example:
- 1 LinkLift 80
- Stroke : 4500 + 200 + 160 = 4860
mm
- Magazine : 5000
- Shaft : A
- Option : Special keyed shaft + 100
mm
The installation of our products is
very simple but must be carried out in conformity to
the instructions attached with each delivery.
