ABSTRACT:
A load support is arranged to be connected to a parachute and has a center guide tube slidably receiving a landing rod. This landing rod is of a sufficient length to project beyond the lower end of the guide tube so as to engage the ground ahead of the load support. A slidable friction connection is provided between the landing rod and the load support for cushioning the landing shock of such support. Brake pads are used as the friction connection, and such brake pads are associated with adjustment apparatus comprising a rotatable holder for the brake pads and a cam and cam follower assembly which serves to adjust the compression of the brake pads on the rod upon rotation of the holder. A pinion and gear connection is provided between the holder and the support to provide the rotatable adjustment.
