~$135 + tax / shipping, and whatever small cost for a load basket.


Place I used to work at had a metal basket restrained by 4 vertical RHS
members. It had PVC or nylon runner wheels on each corner to locate /
restrain the basket. Lift provided by electric chain block. Worked well and
was passed by OH&S inspectors. it had gates with interlocks at ground level
and first floor.
