Q. What should one do if a wheelchair bound individual requests on Shabbos to be wheeled to or from his Shabbos host, when the eruv is either unreliable or one personally have a minhag not to rely on it?

A. Horav Kalman Ochs Shlit’a maintains that if the eruv is truly unreliable he should not use it. 
Horav Shlomo Miller’s Shlit’a opinion is that if the person pushing the wheelchair usually relies on the existing Eruv and carries on Shabbos, he may also push the wheelchair.

The Rov added as an additional point to be lenient, that the top part of the wheelchair is usually over ten tefachim high (about 1m.) and that is a ‘Makom P’tur’ or exempt area.
