4 tons TC4810 Top Climbing Mini Tower Cranes 380v/50hz Power Civil Projects
Shot introduction
1. Fixed Tower Cranes are fixed to the ground on a concrete base
2. The base is connected to the mast sections which offers the crane its height.
3. Further the mast section is attached to the slewing unit (lower slewing table, slewing bearing, upper slewing table and slewing body) that allows the crane to rotate.
4. The slewing unit is connected to three parts which are: horizontal jib / boom, shorter counter-jib, and tower cat.
