3 Terms and Definitions
Those defined in GB 9706.1-2007 AND the following terms and definitions are
applicable to this document.
5.1.5 Suspension belt
5.1.5.1 Adjustment and locking
The suspension belt shall be equipped with adjustment and locking device, and easily
operable. Locking shall be safe and reliable; easily recognizable and safely operated.
It shall be manually operated without the help of any instruments.
5.1.5.2 Width
The suspension belt shall be reasonably designed. The suspension belt that contacts
the buttock shall use soft materials; the edges shall be smooth; the width shall not be
less than 80 mm.
5.2 Walk Training Platform
5.2.1 Timing setting
The walk training platform shall have timing function; the timing error shall not be more
than ± 1% of the set value, and not more than ± 1 min at the maximum.
5.2.2 Speed setting
The walk training platform shall have the function of speed control. Speed output shall
guarantee accuracy and uniformity. The deviation of accuracy shall not exceed ± 5%;
the deviation of uniformity shall not exceed 1 m/s. Speed shall be continuously
adjustable within the range stipulated by the manufacturer; the lowest speed shall not
exceed 0.5 km/h.
5.2.3 Gradient setting
In terms of walk training platform which has the function of gradient adjustment,
gradient shall be continuously adjustable. It shall also have the function of adjustment
indication; the deviation of gradient indication shall not exceed ± 10%.
5.2.4 Static load
The walk training platform shall be able to maintain intact after supporting 6 times of
the normal load stipulated by the manufacturer.
5.2.5 Safety of unexpected power outage
As power supply recovers after unexpected power outage, the walk training platform
would not automatically operate.
5.2.6 Emergency stop device
Except from the power switch, the equipment shall also provide an emergency stop
button, which can stop the training program at any time. This button shall take effect
6.2.4 Static load
Conduct the test in accordance with the requirement in 6.6 in GB 17498.6-2008; it shall
comply with the requirement in 5.2.4.
6.2.5 Safety of unexpected power outage
Conduct the test in practical operation; it shall comply with the requirement in 5.2.5.
6.2.6 Emergency stop device
Conduct the test in visual inspection and practical operation; it shall comply with the
requirement in 5.2.6.
6.2.7 Fatigue test
In the test, simulate the equipment’s moving components in 100,000 times of no-load
operation. After that, the equipment’s function shall still satisfy the requirement in 5.2.7.
6.3 Overall Requirements of Equipment
6.3.1 Stability
Place the overall equipment on a flat surface; use a feeler gauge to measure the
distance between the footing and the flat surface.
In the equipment’s suspended device part, load the normal load stipulated by the
manufacturer. In accordance with the movement direction under normal training state,
or the direction which is the most unfavorable to stability, start to roll over from
horizontal. Use a protractor (precision. superior to 0.1°) to record the rolling-over angle.
The overall equipment shall be placed on a cement ground in accordance with the
requirement in the instruction. If there are trundles, lock the trundles. In the direction
of force, in the most unfavorable location at 1.5 m height of the equipment, impose 120
(1 ± 2%) N of horizontal pull or thrust; observe whether the equipment has moved.
The above test result shall comply with the requirement in 5.3.1.
6.3.2 Operating noise
Place the equipment on a hard table and at a distance of at least 3 m from the walls or
other reflectors. Under the environment where background noise is 10 dB lower than
the measuring point in the sound pressure level, operate the equipment under normal
working state where the maximum noise might be generated; measure A-weighted
sound level in the front, the back, the left, the right and the top of the host device of the
equipment; they shall all satisfy the requirement in 5.3.2. If the manufacturer stipulates
equipment’s special installation or arrangement conditions in the attached documents,
the equipment can be arranged merely in accordance with the method stipulated by
