研发一种配重同步移动的前端为悬臂的折臂式塔机,利用俯仰机构增加辅助卷筒实现配重随臂架的俯仰而同步移动,有效减小了塔身承受的弯矩,降低了制造成本;臂架前端为悬臂解决了现有折臂塔机因其前臂带撑杆和拉杆而导致制作成本高以及安装、拆卸难度大的问题。
In order to reduce the bending moment of the tower body and reduce the bending moment of the tower body, a counterweight arm tower crane with a front end with a cantilever is developed. By using the pitch mechanism to increase the auxiliary drum, the counterweight moves synchronously with the pitch of the boom. Manufacturing cost. The front end of the boom is a cantilever, which solves the problems of high production cost, difficulty of installation and disassembly caused by the forearm boom with the support rod and the pull rod.
