dinette/sofa configuration.

                  12 amps (2 beds or 1 bed and 1 sofa/dinette configuration going up)

 = 450 pounds dynamic (moving) load 

                           600 pounds static (stationary) load

These ratings are for the lifting mechanism only. HappiJac does not manufacture and therefore does

the responsibility of the manufacturer.
