Bertec Corporation Instrumented Treadmill Manual 09
Proper preparation of the installation site will ensure that the performance of the Bertec Instrumented Treadmill is maximized.
The following guidelines are provided so that the treadmill can be properly installed and optimally operated. Note that the actual
conditions and setup at each individual installation site might be different than the ones depicted in this guideline.
Some of the arrangements and constructions mentioned in this guideline might take a long time to make. Therefore, sufcient
time should be spared for planning and site preparation. This guideline describes the steps to be taken by the customer before
installation takes place. Installation and maintenance of the treadmill should be done by authorized personnel only.
General Considerations and Recommendations
The treadmill is designed for indoor use only. It should not be subjected to excessive moisture or dust. Its place of installation
should be maintained at a temperature between 55˚F and 90˚F.
To obtain a high quality measurement from Bertec treadmills, they should be installed in a way that is suitable for the type of
measurement to be performed. First of all, the oor and structure underneath should be prepared to be as rigid as possible in
order to minimize any vibrations.
Depending on the laboratory setup, Bertec Instrumented Treadmills can be installed directly on to the oor or into a specially
constructed pit to have the walking surfaces of the treads ush with the rest of the oor. The pit might be constructed either by
digging into the existing oor or by raising the oor around the treadmill. In case of a pit installation, the void pit space around
the treadmill should be lled with suspended ooring for safety reasons. For accurate measurements the suspended ooring
should not touch the treadmill. At least ½” gap is recommended between the treadmill and the surrounding oor. It is strongly
recommended that the false ooring around the treadmill is custom tted after the installation is completed. The individual units
of the false ooring should be easily removable so that periodic maintenance service can be performed. Although Bertec does
not provide pit and false ooring design and installation services, we encourage the customers to consult with us about their
nal designs.
Installation of the treadmill is done in two steps:
> Step 1: Installation of the mounting plate(s). The epoxy for the mounting plates needs to cure overnight to set properly.
> Step 2: Installation of the individual treads, handrails and assembly of the electronics cabinet followed by testing and user
training to run the system.
Bertec Instrumented Treadmills are mounted on special precision-machined aluminum mounting plates. The mounting plates
are attached to the oor (or to the bottom surface of the pit) using a special two-part epoxy. A bare concrete underlying surface
is ideal for mounting plate attachment. A oor covered with tiles, linoleum etc. might cause a decrease in the performance of the
treadmill. The concrete surface should be properly leveled so that it is at within ±3 mm (±⅛”) tolerance. The concrete surface
should be cleaned with a vacuum cleaner and should be free of any dust and particles. It is the customer’s responsibility to bring
the installation site up to the specs.
Dual Belt Instrumented Treadmills are designed such that the right and left treads are mechanically isolated from each other to
prevent transmission of impact forces between treads. However, structurally weak oors might cause unwanted vibrations that
affect treadmill operation. Floor vibration, especially in the upper stories of the buildings, is a common occurrence. Therefore, it
is strongly recommended that the treadmill be installed in the building at the entrance level with no basement underneath, or at
the basement level. Otherwise, it is the customer’s responsibility to make sure that oor vibration is not going to affect operation
of the treadmill.
