Wedgemounts
Precision levelling mounts for a wide range of applications
Standard Wedgemounts
WL, WLF, WLB, WLT
Performance
Developed and manufactured by Farrat and used for decades in countless applications worldwide, these screw driven, vertical rise wedge adjustment machine mounts are the ideal solution
for accurate, efficient and economical machine installations.
Features
- Precision vertical levelling adjustment with no horizontal forces applied when adjusting.
- High ratio of lifting force to adjustment torque to ensure accurate and smooth levelling.
- Enhanced machine stability (the machine is not sitting on the screw thread).
- Vibration Damping (in some variants).
- Allow for easy installation and relocation of the machinery to provide factory layout flexibility.
Typical Applications
- General Machine Tools.
- Printing machines.
- CNC lathes and machining centres.
- Boring and milling machines.
- Grinding machines.
- Transfer machines.
- Rolling mills.
- Sensitive / test equipment.
- Injection moulding machines.
- Die-casting machines.
- Long bed machinery.
- Buildings and structures.
- Civil Engineering.
Farrat Precision Levelling Elements (WL-LE), where the top and bottom faces are fully machined, provide a rigid support for maximum stiffness. WL-LEs are used for supporting and levelling machinery during construction, erection and operation. They can be installed free standing for machines without strong dynamic forces or in conjunction with holding down bolts located alongside the WL-LE units.
WL-LEs are supplied as: Freestanding (FS), Bolt On (BO), Bolt Through (BT) and Aluminium (WLF-LE-AL).
All WL-LEs can be supplied with optional Spheriseats (SPS) which can be placed on the WL-LE units to take up complex angles between the floor and machine base.
