Fixed-point crane for aerated concrete

Aerated concrete cranes are specialized cranes designed for lifting concrete molds and blanks. They consist of a box-shaped bridge, a trolley operating mechanism, a hoisting mechanism, and electrical equipment. Used in conjunction with specialized lifting equipment, they perform tasks such as mold flipping, mold opening, and demolding. The hoisting mechanism is fixed between two main beams and consists of an electric motor, a reducer, a brake, a drum, and a guide pulley. A wire rope is spooled from the drum and wound through pulleys fixed to the bridge or trolley at either end, then onto the pulleys on the hoisting mechanism, creating a dual lifting point. The trolley operating mechanism utilizes a separate drive system with a conical motor brake and an open gear transmission. The operating motor can be equipped with a soft-start motor or variable frequency speed control, depending on the user’s requirements, ensuring smooth crane startup and safe and reliable operation.
