Product Description
QTZ315(TC7030)-Max. Load 16t Chinese Tower Crane Stationary tower crane Self-erecting tower crane
QTZ315(TC7030) self-elevating tower crane consists of metal structure, component driving, hydraulic jack-up, electric control and safety protection device. Here is brief introduction of each part and their characteristics: The under-frame of whole machine is tightly fixed on special concrete foundation. Its upper part is connected with tower body; the upper end of tower body is connected with jack-up set frame and lower turn-table, and the surface of lower turn-table is connected with the outer ring of slewing bearing. The rotating part fixed on the inner ring of slewing bearing includes rotary upper turn-table, tower cap, balance arm, crane boom, trolley and hooks, counterweight, hoisting mechanism, slewing mechanism, and cab. These components can all rotate fully to 540°around tower body axis line in their respective horizontal plane. The crane boom is connected with tower cap by two boom pull rods and its root is connected with upper turn-table pin. The balance arm is connected tower cap by two boom pull rods and its root is connected with upper turn-table pin. The hoisting mechanism is set at the rear of balance arm. The slewing mechanism lies on the right of rotary upper turn-table and cab on the left. The trolley and hooks are drawn by luffing mechanism close to the root of boom root, in vertical reciprocating motion along with longitudinal axis of crane boom.
