For testing applications requiring three individual axes, we recommend an trunnion-mounted shaker and a slip table. A slip table typically consists of a magnesium plate sitting at Top a smooth granite block, with a lubricating film in between. Both are housed in a frame that connects to the shaker’s armature, enabling it to excite payloads in the horizontal position.
Like the SL series but with reduced stiffness and load-bearing capability, SL slip tables are suitable for general-purpose vibration testing systems. They offer a cost-effective solution for most R&D and product verification applications, including testing of military equipment, electronic assemblies, and aircraft and automotive components.

STAND-ALONE SLIP TABLES OR COMBO SYSTEMS – WHAT TO CHOOSE?
Designed with flexibility and performance in mind, LDS® LPT Slip Tables can be supplied either as stand-alone or with a shaker, as part of a system mounted on a solid frame (or ‘combo’ base).
· Combo systems: For three-axis testing applications, we recommend the combo configuration, as it offers easy installation and accurate alignment between shaker and table, reducing test setup time when switching the position from vertical to horizontal.
· Stand-alone slip tables: A trunnion-mounted shaker with a separate slip table on a seismic base is the favoured arrangement for testing large or dynamically complex payloads, as it delivers optimal pitch, roll and yaw restraints.
While it is possible to purchase a stand-alone slip table for retrofitting with an existing shaker, the combo option is preferable in most cases, as the former is a more expensive, time-consuming endeavour that involves system downtime for installation and regular calibration, potential misalignment issues, and ongoing maintenance costs.
