A swivel joint according to the present invention includes first and second base members. A spider includes first and second arcuate surfaces which form joints with the first and second base members, respectively. Furthermore, the spider includes first and second pins both opposed from each other and third and fourth pins opposed from each other. A first mechanism is coupled to the spider and the first base member and is adapted to effect a force between the first arcuate surface and the first base member. Also, a second mechanism is coupled to the spider and the second base member and is adapted to effect a force between the second arcuate surface and the second base member.
