The slewing mechanism of Concrete Placing Boom is closed braking mode, that is, except for gyration motor to pass oil, all the slewing brakes are closed, the whole machine can not rotate and its mix feeding arm is fixed, to prevent the collision. Wireless remote control and wired remote control are its two control modes. And with its multiple security devices, it is high in safety and low in use cost. The conveying winding pipe of Concrete Placing Boom is precision casting and its wall thickness is curve forming, ensuring uniform abrasion and improving its service life.
