The invention relates to the field of building crane equipment, in particular to a tower head and a tower crane, the tower head comprises a T-shaped tower top, two main chord members, two diagonal web members and two diagonal support rods; the T-shaped tower top comprises a transverse tower top assembly and a longitudinal tower top assembly which are vertically connected; one end of the diagonal web member and one end of the main chord member are connected with the end of the transverse tower top assembly; one end of the diagonal stay bar is connected with one end of the longitudinal tower top assembly away from the transverse tower top assembly. The T-shaped tower top frame of the tower head is composed of the transverse tower top assembly and the longitudinal tower top assembly, and the material utilization rate for manufacturing the transverse tower top assembly and the longitudinal tower top assembly is higher than that for manufacturing a triangular tower top frame by digging out a small triangular plate in the middle of an existing triangular plate.
本申请涉及建筑起重机设备领域,具体涉及一种塔头和塔式起重机,该塔头包括T型塔顶、两个主弦杆、两个斜腹杆、两个斜撑杆;T型塔顶包括垂直连接的横向塔顶组件和纵向塔顶组件;斜腹杆和主弦杆一端连接横向塔顶组件的端部,斜撑杆一端连接纵向塔顶组件远离横向塔顶组件的一端。本发明的塔头的T型塔顶框架是横向塔顶组件和纵向塔顶组件组成,制造横向塔顶组件和纵向塔顶组件组成的材料利用率,相比现有采用一个三角板中间挖去一个小三角板制造三角形塔顶框架的材料利用率更高。
