Drum lifter 1

Mechanism shown at    • Automatic 90 deg. switch 3   is applied to this lifter. Input: blue cam block moving up-down. Green frame has prismatic joint with the cam block. Orange angular levers, brown conrods, the cam block and the frame create slider-crank mechanisms. For lifting the drum yellow T-hook is set to be below green traverse of rectangular hole. This position makes distances between hooks of the orange levers larger than the drum diameter. Then the cam block moves down. When the frame contacts the drum, further down and up motion of the cam block makes the yellow hook turn 90 deg. Now the latter can move up through the hole of the green traverse and reduce distances between hooks of the orange levers. Thus, the lifter can lift the drum. The process of placing the drum on the ground is carried out in the same way.
