What are the working mechanisms and safety devices of tower cranes?
A safety device: four limit: height limit, amplitude limit, slewing limit, travel limit; three insurance: luffing rope insurance, car insurance broken shaft, the hook to prevent falling insurance; two limit: torque limiter, weight limiter on these roughly.
About the structure: Tower cranes are all metal structures, so far there is no wood. About institutions: tower crane working mechanisms are: winding lifting mechanism; luffing mechanism; slewing mechanism; cart moving mechanism; lifting mechanism.
