A six-bar linkage mechanism for conforming to the configuration of a tractored surface having a central link defined by a tool body and a saddle link spaced from the central link and movable for conforming with the tractored surface. A pair of front links each having pivotal connection with respective ends of the saddle link and having linearly movable pivotal connection with the central link to permit angular and spacing changes of the saddle link relative to the central link. A pair of centralizer links are located between the front links and have pivotal connections with the saddle link and pivotal connections with the central link. One of the pivotal connections is linearly movable on the central link. For tractor tools, when the tractored surface is a wellbore or well pipe, a plurality of six-bar linkages radiate from a tool body for surface conforming traction with the tractored surface.

A compression device, useful for applying circumferential compression to an object, for example, as a tourniquet to occlude blood flow in a hemorrhaging extremity, is provided. The device includes a buckle assembly, first and second guidance slides, a connecting member between the first and second guidance slides, and a strap. Each end of the strap is anchored to a guidance slide. From each of the anchored ends, the strap passes through the buckle assembly, forming outer segments. The strap then returns along respective insides of the outer segments and through the guidance slides, forming inner segments. The buckle assembly, inner segments and connecting member form a loop for placing about an object, an inner circumference of the loop being adjustable by pulling on a portion of the strap located along the outside of the connecting member and between the two guidance slides to tighten the loop around the object.
