Wheeling a chair onto a platform scale is easier when there is a ramp on both sides, because the person pushing can roll straight through without reversing off. The seca 470 is a second drive up ramp for compatible seca platform scales, so you can set up a clean entry and exit.
The surface is shallow and wide enough to take a wheelchair without the front castors catching, and the ramp sits flush against the platform edge. For the carer, a through path removes the reversing manoeuvre that is often the most awkward part of weighing someone in a chair.
It is worth adding wherever a platform scale is in a corridor, a tight treatment room or anywhere a three point turn is a nuisance.
