Level Luffing Crane

Level-luffing crane includes the following main structures:
  1. Traveling mechanism: The crane can move along rails or other flat surfaces.
  2. Slewing mechanism: Allows the crane to rotate around its vertical axis, expanding its operating range.
  3. Luffing mechanism: Controls the up and down movement of the boom, helping to change the distance between the crane hook and the base of the boom.
  4. Lifting mechanism: Controls the lifting and lowering of loads, including cables and pulley systems.
