Tower Crane QTZ63
The QTZ63 hammerhead tower crane has a vertical arm support, trolley travel and up-rotary hydraulic jack-up system. Its maximum effective amplitude is 50m - the only domestic tower crane to reach this amplitude. Its maximum lifting moment is 630kN·m. When used alone, the hoisting machinery has a lifting height of 30-40m and a lifting height with attachments of 150 m (α=2). Each speed index of this crane has reached or exceeded national standards.
The weight of the hoisting and conveying machinery (not including counterweights and attached devices) is 31.15 tons, and the overall installed capacity is 34.7kW. With advanced parameters, reliable performance, excellent quality, and simple structure, this tower crane is ideal construction machinery for small to mid-sized construction businesses. It also features advanced security devices, convenient maintenance, and an affordable price.
