Interior Climbing Crane Slewing institutions and balance mechanism design Abstract: With the further development of China's reform and opening up the situation, the growing variety of high-rise building, use the inner climbing tower crane brought significant economic and social benefits. 内爬式塔式起重机安装在建筑物内部（如电梯井，楼梯间等），依靠爬升机构，使塔身随建筑物建高而不断升高。 Interior Climbing tower cranes installed within the building (such as elevator shafts, stairwells, etc.), relying on climbing mechanism to build the tower with the high rising buildings. 随着建筑业的高速发展, 内爬式塔式起重机在高层与超高层建筑的施工中必将得到广泛应用。 With the rapid development of the construction industry, internal climbing tower crane in high-rise and high-rise building construction will be widely applied. 爬升装置的内塔与外塔同时安装，内塔每次爬升后不用拆出电梯井，爬升前也不用重新安装，回转机构依靠回转支承装置与小齿轮的啮合回转，平衡块在平衡臂上的移动来保持平衡臂和起重臂的力矩相等来保持塔机的平衡。 Climbing tower and inside devices be installed outside the tower, which towers do not have time to climb after the demolition of the elevator shaft, climb the former need not re-installed, depend on slewing bearing slewing devices and small gears meshing rotation, balance in the balance arm block move to balance the torque arm and lifting arm to keep the tower equal to the balance.

Design of the Slewing Mechanism and Balance Mechanism of Inside-self-elevating Type Tower Crane
Abstract: With the further development of China’s reform and opening situation various types of high rise building are increasing continuously, so the use of inside-self-elevating type tower crane leads to significant economic and social benefits. The inside-self-
elevating type tower crane is installed inside of the building (e.g. elevator shaft, stairwell), and its crane body is elevated with the elevation of the building by the elevating mechanism. With the high-speed development of construction industry inside-self-elevating type tower crane will certainly be widely used in the construction of high rise and super high rise buildings. The inside tower and outside tower are installed simultaneously, and it is unnecessary to remove the inside tower out of the elevator shaft and reinstall it before elevation. The slewing of the slewing mechanism is implemented by the rotation supporting device and the engagement with small gears, and the balance of the crane is realized by the moving of balance block in the balance arm and resulting in the equation of the moments of balance arm and elevating arm.

希望能够帮助到你，祝你好运。In slewing crane climbing and balancing mechanism design
Abstract: With the further development of China's reform and opening up the situation, the growing variety of high-rise building, climbing tower cranes used in the economic benefits and social benefits are significant. Climbing tower cranes installed within the building interior (such as elevator shafts, stairwells, etc.), relying on climbing mechanism to build the tower with the high rising buildings. With the rapid development of the construction industry, internal climbing tower crane in high-rise and high-rise building construction will be widely applied. Within the tower and climb devices be installed outside the tower, climb inside the tower each time the elevator shaft after the not dismantled, former climbing need not re-installed, depend on slewing bearing slewing devices and small gears meshing rotation, balance in the balance arm block move to balance the torque arm and lifting arm to keep the tower equal to the balance.

Design of swing and balancing mechanism for internal-climbing Crane
Abstract: With the further development of China's reform and opening up and the increasing various high buildings,the using of internal-climbing tower crane that the economic effectiveness and social effect it brings are highly significant. Internal-climbing tower cranes being installed in the interior of buildings, such as elevator shafts and stair halls, making use of climbing mechanism, thus make the tower body reach higher with the building carrying up. With the rapid development of construction industry, internal-climbing tower cranes would get widespread use in the construction of high and
super-high buildings.The inner and outer towers of the climbing device
are installed simultaneously. The outer towers don't need to be removed from the elevator shaft after climbing up each time and installed again before climbing, swing mechanism relies on the meshing and rotatory of slewing bearing equipment and pinion, and the movements of balance weight on the balance arms to keep momentofforces of balance arms and outriggers equal to keep the balance of tower cranes.
