The invention relates to a mast crane. The mast crane comprises a front vehicle base, an operation arm, a rear vehicle chassis, a counterweight platform, a propeller strut front supporting rod and a propeller strut rear supporting rod, wherein the front vehicle base comprises a vehicle frame and a rotary table rotatably arranged on the vehicle frame; the bottom of the operation arm is hinged to the rotary table; the rear vehicle chassis is configured to be in contact with the ground; the counterweight platform is movably arranged on the rear vehicle chassis and connected with the rotary table; the bottom of the propeller strut front supporting rod is hinged to the rotary table; and the bottom of the propeller strut rear supporting rod is hinged to the counterweight platform. According to the mast crane, the rear vehicle chassis is arranged, and the counterweight platform is movably arranged on the rear vehicle chassis and connected with the rotary table, so that the counterweight platform can rotate around the rotary table on the rear vehicle chassis, heavy objects can move in the rotating direction, the operation adaptability is wide, and the application range of the mast crane is expanded.

    本公开涉及一种桅杆起重机,包括:前车底座,其包括车架和转台,转台为可回转地设置在车架上;作业臂,其底部铰接在转台上;后车底盘,被配置为与地面接触;配重平台,可移动地设置在后车底盘上并与转台连接;人字架前撑杆,其底部与转台铰接;以及人字架后撑杆,其底部与配重平台铰接。通过设置后车底盘,并将配重平台可移动地设置在后车底盘上并与转台连接,实现了配重平台在后车底盘上绕转台回转移动,实现重物的回转方向移动,作业适应性广,扩大了桅杆起重机的适用范围。
