Precision Wedge Levelling
Elements
Precision machine levelling mounts for long bed and precision machinery
WL-LEs provide a system of installation of large or heavy equipment which require a very rigid connection to their foundations and which also require very accurate alignment for satisfactory performance; for example machines which are subjected to significant changes in load distribution during operation. Farrat Precision Wedge Levelling Elements (WL-LE) can be used for supporting and levelling machinery and equipment during construction, erection and operation.
WL-LEs are the same basic form as standard Wedgemount but the top and bottom faces are precision machined to provide an accurate, rigid support for maximum stiffness.
Use Farrat Precision Levelling Elements where
all or some of the following criteria are required:
- Rigid machine to foundation integration.
- Precision adjustment to obtain very fine alignment.
- Systemised heavy machine installation.
- A very high degree of machine bed stiffness (by conversion of support points from pivot support to a virtually fixed or built-in support).
- A very tight connection between the machine and floor
without distortion of the machine bed. The tighter the connection the more the concrete will integrate itself with the machine thus increasing the reinforcing effect of the concrete.
- Facility to carry out subsequent readjustments
to alignment to correct foundation settlements and
movements which may occur from time to time.
- Support for machines which are subjected to
significant changes in load distribution during operation.
Typical Applications
- Levelling and supporting heavy components on machine tool tables.
- Long bed machinery.
- Large boring and milling machines.
- Grinding machines.
- Transfer machines.
- Rolling mills.
- Gas turbines.
- Large compressors.
- Nuclear reactors.
- Buildings and structures.
Where WL-LEs do not provide sufficient load bearing
capacity or machine anchoring you may wish to consider
Farrat Levalators.

Screw Extenders (SX-WL)
Screw Extenders are used where Wedgemounts need to be placed inwards of the outer edge where access to the adjustment bolt is restricted. They are made to order according to customer requirements depending on the lenght and the Wedgemount Type.
Farrat Precision Wedge Levelling Elements, (sometimes referred to as Wedgemounts, wedge mounts, jacmounts, levelers, adjustable anchors, leveling feet, leveling elements, adjustable mounts, machine bearing elements etc), are the ideal choice for the installation and levelling of precision and long bed machinery.
