桅杆起重机 以桅杆为机身的动臂旋转起重机。 由桅杆、 动臂、支撑装置和起升、变幅、回转机构组成。①桅杆竖直架设，在回转机构驱动下能绕本身轴线旋转。桅杆虽有支撑装置，但很难严格保持直立，故回转机构采用钢丝绳传动，即在桅杆底部装上转盘，外绕钢丝绳，用可逆转的卷扬机来回牵引，使桅杆转动。②动臂与桅杆下部铰接,随桅杆一起转动,并在变幅滑轮组作用下可俯仰变幅。③支撑装置用来把桅杆支撑在竖直位置。④起重、变幅、回转卷扬机都装在起重机外部机房内。 按支撑方式分斜撑式桅杆起重机和纤缆式桅杆起重机。斜撑式桅杆起重机用两根钢性斜撑支持桅杆，动臂比桅杆长，只能在270°以内回转,但起重机占地面积小。纤缆式桅杆起重机用多根缆绳稳定桅杆，动臂比桅杆短，能作360°回转。 桅杆起重机一般都利用自身变幅滑轮组和绳索自行架设，具有结构轻便、传动简单、装拆容易等优点。广泛应用于定点装卸重物和安装大型设备。
