<div dir="ltr">Have you considered something mechanical....either a hand winch or a running block rig. Tie off the line at the top of the ramp, reeve it through a block attached to the platform and then back up through the top of the ramp. Should be a pretty easy hand over hand pull. Electric motors, even variable speed motors, have lots of torque and really require a number of safeties, e-stops, end of ramp power cut off etc to ensure safety....not to mention noise.<br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div>---------------------------------------------------------------------------------<br></div><div>Kim Hartshorn</div><div><br></div><div><br></div></div></div></div></div></div>
