Description of Components
5.4.1
Walking Surface Belt
The patented walking surface consists of 60 slats which are mounted on a set of endless combination
wedged-toothed belts. These are connected with the drive via the gear wheel. The teeth prevent
slipping and allow for exact reproduction of the distance.
The individual slats consist of two components. The base is a solid aluminum profile and the tread is
comprised of a high-traction rubber compound. The combination
makes it “the softest treadmill in
the world”.
The
approx. ½” (1.2 cm)
thick rubber surface significantly reduces the impact energy, thus making
WOODWAY
treadmills much easier on the joints than conventional treadmills.
5.4.2
Transport Systyem
The support system consists of 2 supporting/secondary rails, which are equipped with high-
performance bearings. V-belt guides (6) on each rail ensure lateral stability. The rollers transfer the
load to and from the motor and prevent the running belt from slipping through.
The system, which consists of a total of 112 ball bearings, supports the running surface and distributes
the load evenly over the entire treadmill. The running surface belt (slats and steel-wire reinforced,
toothed V-belt) is guided by form-fitted drive pulleys on the front and back. The device can even be
used without external drive, simply by pushing the treadmill to start the belt moving. The combination
of running surface, secondary bearing rails, and drive pulleys gives this slat system unique
characteristics:
•
Low friction (energy saving)
•
Low wear (approx. 150,000 mile [240,000 km] functional service life)
•
100% power transfer through the form-fitted, toothed V-belt system
•
High service life (one running surface belt for one treadmill life)
5.4.3
Incline System
The PPS Series treadmills have lifting scissors with casters. This makes a maximum incline of 25%
possible (incline capabilities depend on the model). The lifting system is driven by a linear DC motor
which changes the angle of the scissors, thus changes the incline of the running belt and absorbs a
large proportion of the weight of the treadmill and the body weight of the user during an incline run.
The incline system is characterized by a very quiet operation. The system accuracy is 0.1% and +/- 0.4
degrees.
The end switches limit the distance covered by the lifting system and are constantly in use. The Data
Monitor (DaMo) recognizes when the treadmill has triggered the 0% end switch.
