Equipment Overview: General Description
After the ESTOP button is released, the walking belt enters an unlocked
state for 20 seconds.
The 3 HP brushless DC motor is controlled by a separate control box, and
connects directly to the front roller with a drive belt. A 15-pound
flywheel, attached to the motor's drive shaft, keeps "footfall" variance to
a minimum. An "adjustment plate" above the motor mounting bracket
contains two vertical bolts for adjusting the drive belt tension.
The GE T2100 Treadmill can accommodate a weight capacity up to 450
lbs.
The elevation system uses a rack and pinion operation to raise and lower
the GE T2100 Treadmill rather than jack screws and chains. The
elevation motor attaches to a small gearbox that connects to the pinion
shaft. The upper- and lower-limit switches are mounted on a fixed block
in contact with a rack, making them easy to reach and adjust. Replacing
the elevation motor only requires the removal of the three mounting
bolts and detaching the motor from the pinion shaft coupling.
The one-piece bed assembly, with side rails and struts bolted together,
enables quick belt and bed replacement for field service personnel.
An isolated "electronics box" (e-box) contains the power supply PCB,
control PCB, +24 V power supply, and an EMI Filter. The box is
accessible with the shroud removed and contains parts that can be
replaced in the field.
