Hammerhead Tower Crane TC7550-25

The performance of hoisting mechanism, slewing mechanism, trolleying mechanism and traveling mechanism directly affects the whole performance of the tower crane. Users hope that the crane is stable and reliable in working. The main factor influenced the stability of the crane is inertial impact and electric current impact. "Mingwei" has solved those knotty problems with advanced technology in the TC7040 tower crane.
