This machine has been designed to perform CBR,
Marshall and load/strain related tests, e.g. Quick
Undrained Triaxial Tests and unconfined compression
The apparatus consists of a load frame, with an
adjustable top crosshead, mounted on columns
attached to a sturdy base casting, figure 1, giving
exceptional rigidity for maximum accuracy of results.
The base casting houses a geared screwjack onto
which the platen is attached, figure 2. The platen is
driven upward centrally between the columns of the
load frame at the constant rate selected.
Motive power from an electric motor drives the
screwjack via a multi-vee drive belt. Platen speed is
accurately maintained by a tacho feedback system.
The base casting is totally enclosed giving full
protection to mechanism and electrics, yet providing
an easy-clean surface. The front panel hinges
downwards providing access to the machines
electrical components, while the top cover is
removable making the mechanical components of the
machine readily accessible.
Centrally under the crosshead, is provision for
attaching a load ring or load transducer of up to
50 kN capacity.
The platen movement is controlled by the micro-
processor and accessed via five push buttons situated
on the front panel.
A facility to manually move the platen is provided.
Access to this is obtai
