True Speed Soil Frame
Product Code : JA-ST-9784
The True Speed Soil Frame (SKU JA-ST-9784) is a load frame for routine soil tests such as California bearing ratio (CBR), unconfined compressive strength (UCS) and triaxial tests. Its platen speed is held by an internal feedback system instead of a fixed gear train, so the displacement rate stays within 5% of the set value as the load rises. It comes in 4-speed and 34-speed versions and is supplied by JaincoLab.
Specifications
The table gives the two versions and the speed-control data stated for the frame.

| Speed accuracy | Speed drop within 5% of the displacement rate across the fixed speeds |
| Typical tests | CBR, UCS, triaxial and other routine soil tests |
Tests run on the true speed soil load frame
The frame drives the platen at a set displacement rate, which is what these laboratory tests need:
- California bearing ratio (CBR) tests on compacted soil specimens
- Unconfined compressive strength (UCS) tests on cohesive soil samples
- Triaxial compression tests with a triaxial cell and load measuring device
- Routine strength testing in highway, foundation and teaching laboratories
Scope of supply and ordering
Name the 4-speed or 34-speed version when ordering; the listing covers the load frame, and cells, moulds or proving rings are quoted as separate lines. Quantities, packing and lead time are confirmed on the quotation.
Frequently asked questions
What is the difference between the 4-speed and 34-speed versions?
They differ in the number of fixed displacement rates available, four or thirty-four. Both use the internal feedback drive, and the speed values of each version are listed on the quotation.
How closely is the platen speed held?
Because speed is set by an internal feedback system rather than fixed gears, the speed drop is held within 5% of the displacement rate across the fixed speeds, even as the load increases.
Which tests can be run on the frame?
It is used for CBR, UCS, triaxial and other routine soil tests that need a constant rate of displacement.
