2. Differential pulley - Wikipedia

   en.wikipedia.org/wiki/Differential_pulley

   A dumb pulley can lift very large masses a short distance. It consists of two fixed pulleys of unequal radii that are attached to each other and rotate together, a single pulley bearing the load, and an endless rope looped around the pulleys. To avoid slippage, the rope is usually replaced by a chain, and the connected pulleys by sprockets.

3. Precast concrete lifting anchor system - Wikipedia

   en.wikipedia.org/wiki/Precast_concrete_lifting...

   As the orientation of the void determines the lift position of the lifting clutch, the wire chair can be secured against the element reinforcement to maintain this orientation during the concrete pour and set. When an anchors load resistance must consider load reduction factors, this would imply that the particular selected anchor will form a ...

4. Block and tackle - Wikipedia

   en.wikipedia.org/wiki/Block_and_tackle

   The mechanical advantage is 2, requiring a force of only 50 N to lift the load. A block and tackle is characterized by the use of a single continuous rope to transmit a tension force around one or more pulleys to lift or move a load. Its mechanical advantage is the number of parts of the rope that act on the load. The mechanical advantage of a ...

5. Lift slab construction - Wikipedia

   en.wikipedia.org/wiki/Lift_slab_construction

   Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...

9. Mechanical advantage - Wikipedia

   en.wikipedia.org/wiki/Mechanical_advantage

   A number of pulleys are assembled together to form the blocks, one that is fixed and one that moves with the load. The rope is threaded through the pulleys to provide mechanical advantage that amplifies that force applied to the rope. [4] In order to determine the mechanical advantage of a block and tackle system consider the simple case of a ...
