To do this safely and to comply with the "whistle test" you can use a
device called a Petzl Traxion. The device attaches to a ground anchor or
anchor point with a sling or rope and ears.
That way you can pull the rope hand over hand and if you need a breather
you can just stop pulling.
If you need to lower, you move a small lever on the traxion to allow the
rope to run free, generally I would first take the control rope through
a karabiner with an Italian hitch, with this set-up you can *easily* and
safely lower 400Kg with just two fingers.
Regards Paul
