An apparatus for transporting personnel or other cargo between higher and lower elevations comprising:
- (1) a support frame anchorable at the higher elevation in which frame is mounted:
- a right guideline means spool to which are attached the proximal ends of a right guideline means and a left guideline means and respectively, the distal ends of said guideline means being anchorable to the lower elevation, said guideline means spools having a means for tensioning said guideline means;
- a towline spool means having a right towline and a left towline which towlines are wound around said towline spool means in opposite directions, and
- (2) carrier means suspendable from each guideline means by a pulley means, said carrier means being attachable to the distal end of each towline and positioned such that the carrier means suspended from one guideline means is near or at the higher elevation while the carrier means suspended from the other guideline means is near or at the lower elevation, said carrier means comprising a transverse member whose ends can fit on inclined anti-sag guides attached to the right and left sides of the support frame, said guides being placed such that they support the carrier means as it traverses the length of the guides, said guides extending downward and beyond the front of said support frame.
