   An extended scissor lift. A scissor lift is a type of platform that can usually only move vertically. The mechanism to achieve this is the use of linked, folding supports in a criss-cross X pattern, known as a pantograph (or scissor mechanism). The upward motion is achieved by the application of pressure to the outside of the lowest set of ...

   The leading safety hazards on construction sites include falls, being caught between objects, electrocutions, and being struck by objects. [23] These hazards have caused injuries and deaths on construction sites throughout the world. Failures in hazard identification are often due to limited or improper training and supervision of workers. [24]

5. Scissors mechanism - Wikipedia

   The deployable mirror linkage is constructed from a series of rhombus or scissor linkages. An extended scissor lift. The movement of an ideal joint is generally associated with a subgroup of the group of Euclidean displacements. The number of parameters in the subgroup is called the degrees of freedom (DOF) of the joint. Mechanical linkages are ...
