Vibration tests in three orthogonal directions can be achieved with the connection of a slip table with an electro-dynamic shaker. A slip table uses a smaller carrier (table) to improve the quality of the overall load capacity, capable of supporting big size and large mass of the payload. A slip table can be categorized into combo and standalone types according to the way of connection. A vibration system with a slip table can complete vibration tests for a component or a whole machine in X, Y and Z directions. It can also form an integrated environmental testing system with the use of temperature, humidity test chamber. We are capable of manufacturing super large slip tables, such as the 3.5m by 3.5m etc.
Combo Slip Table
Combo slip table refers to integral design of a horizontal slip table and a shaker. They share a same pedestal.
It has a good rigidity, and is easy to install and adjust. Its installation does not need a special foundation base unless the shaker was required to start testing from 1 Hz.
A horizontal slip table with hydraulic Bearing Guiding consists of a Slip Plate (magnesium or aluminium), Drive Bar (or Bull- Nose), Granite Slab, a built-in Low Pressure Oil Source and Pedestal (or Slip Table Base). Built-in oil pump with compact structure is easy to operate.
Standalone Slip Table
Standalone type design is used widely for testing large-size and dynamically complex test samples. Its transportation, lift and loading are easy and its use is more flexible. Besides, the standalone slip tables are welcome by these customers who have a shaker without a slip table.
BT Series - Journal Hydrostatic Bearing
A slip table with Journal hydrostatic bearings consists of a Slip Plate (magnesium or aluminium), Drive Bar (or Bull-Nose), Granite Slab, a Stand-Alone High-Pressure Oil Source and Pedestal (or Slip Table Base). Journal hydrostatic bearings can provide higher resistance to overturning moment, suitable for testing a large sample load. The more the number of hydrostatic bearings, the greater the resistance to overturning moment.
Easy to operate
Unique trunnion makes horizontal and vertical switching easier and more convenient. For medium and larger thrust shaker, worm wheel mechanism makes switching more effortless.

We Supply many types of standardized head expanders, and support customization of head expander to meet customer’s demand for extended performance of shaker performance. In an actual vibration test, a test piece or fixture is often larger than the armature table of the electro-dynamic shaker, and then you need to extend the original table. Common approach is to install an auxiliary table. In the operating frequencies, the table’s weight, acceleration, amplitude uniformity and lateral movement, etc. have stringent requirements to the head expander.
- High-quality production processes ensure a stable performance and good technical parameters.
- Standard series of head expanders to choose from, shape (round or square), material (aluminium or magnesium) can be chosen
