The invention relates to the technical field of engineering machines and hoisting, in particular to a crawler crane and a hoisting method. The crawler crane comprises a rotating body, a movable arm, apulley block, a variable-amplitude winch and at least three lifting winches. One end of the movable arm is movably arranged on the rotating body, and the pulley block is arranged at the other end ofthe movable arm. The variable-amplitude winch and the lifting winches are all arranged on the rotating body and can be used for enabling the steel wire rope to be in cooperation with the pulley blockto complete the preset action. By the adoption of the crawler crane and the hoisting method, hoisting of a main machine and the percussion and grabbing work can be competed efficiently and fast.
本发明涉及工程机械和起重技术领域,具体而言,涉及一种履带起重机和起重方法。履带起重机包括回转体、动臂、滑轮组、变幅卷扬和至少三个提升卷扬;动臂的一端可活动地设置在回转体上,动臂的另一端设置有滑轮组;变幅卷扬和提升卷扬均设置在回转体上,且变幅卷扬和提升卷扬均能用于将钢丝绳与滑轮组配合以完成预设动作。其能够高效快捷的完成吊运主机和冲抓作业。
