-
Standard ISO 10542-1 approved 4 point WTORS (Wheelchair Tie Down and
Occupant Restraint Systems), are only tested to 85 kg.
-
For wheelchairs heavier than 85 kg it is recommended to use to use an ISO
10542-1 compliant WTORS (Heavy Duty System), which is rated for the total
weight of the wheelchair including any options. If using a Heavy Duty
System, use 4 straps to secure the wheelchair, 2 straps at the front and 2
straps at the back.
-
If using a standard 4 point WTORS for securing a wheelchair heavier than 85
kg, use 6 straps to secure the wheelchair, 2 straps at the front and 4 straps
at the back.
-
Never use equipment not labeled with ISO 10542.
