A support mechanism comprises a base member, first and second support arms, first and second synchronizing arms, and a load-supporting platform. The first support arm is connected to a pivot bracket and the based member in a manner to permit pivoting movement of the first support arm between stowed and deployed positions. The second support arm is connected to the pivot bracket and the load-supporting platform in a manner to permit pivoting movement of the second support arm relative to the load-supporting platform between stowed and deployed positions. The first and second synchronizing arms are also operatively connected to the based member, pivot bracket and load-supporting platform in a manner so that the first synchronizing arm and first support arm maintain a substantially parallel relationship with one another throughout the entire range of movement of the first support arm, and so that the second synchronizing arm and second support arm also maintain a substantially parallel relationship with one another throughout the entire range of movement of the second support arm.

Support mechanism

A bolt cutting tool comprises a bolt engaging portion and a cutting blade. The bolt engaging portion has at least one bolt-receiving bore, which is adapted for receiving a portion of a bolt to be cut. The cutting blade is rotatably connected to the tool generally adjacent the bolt engaging portion. The cutting blade has a cutting surface with an arcuate peripheral cutting edge. The cutting blade is adapted for rotation relative to the bolt-receiving bore from a pre-cut starting position toward a post-cut finishing position. The blade is adapted to rotate in a manner so that the arcuate peripheral cutting edge of the blade cuts the bolt as the cutting blade is rotated toward the post-cut finishing position. The blade is configured so that an angle of incidence between the cutting surface of the blade and a center axis of the bolt-receiving bore is less than 15 degrees when the blade is in its pre-cut starting position.
