The invention discloses a crawler-type telescopic folding arm crane and a construction method, the crawler-type telescopic folding arm crane comprises a crawler-type vehicle body, a telescopic folding arm hoisting mechanism and a rear dragging vehicle body; the telescopic folding arm hoisting mechanism is arranged on the crawler-type vehicle body, the telescopic folding arm hoisting mechanism is provided with a telescopic main arm, an auxiliary arm and a hydraulic winch mechanism, and a twisted rope of the hydraulic winch mechanism is connected with a lifting hook; the crawler-type vehicle body is connected with the rear material dragging vehicle body through the dragging beam, the dragging beam is in sliding fit with the rear material dragging vehicle body, the dragging beam is provided with a limiting piece to prevent the dragging beam from being separated from the rear material dragging vehicle body, and when the crawler-type vehicle body moves, the dragging beam slides relative to the rear material dragging vehicle body so that the crawler-type vehicle body can have a free moving space. The crane can stably, flexibly and efficiently carry out hoisting operation in a limited space, and the problems that an existing truck crane is not convenient to operate and not flexible in transition, and a crawler crane is large and heavy and cannot adapt to flexible hoisting operation in construction areas such as tunnels, deep foundation pits and housing construction are solved.
本发明公开了一种履带式收缩折叠臂起重机及施工方法,该履带式收缩折叠臂起重机,包括:履带式车体、伸缩折叠臂吊装机构和后拖料车体;伸缩折叠臂吊装机构设置在履带式车体上,伸缩折叠臂吊装机构具有伸缩式主臂、副臂和液压绞车机构,液压绞车机构的绞绳连接有吊钩;履带式车体通过拖梁与后拖料车体连接,拖梁与后拖料车体滑动配合,且拖梁设置有限位件防止拖梁脱离后拖料车体,履带式车体移动时,拖梁相对后拖料车体滑动而使得履带式车体具有自由活动空间。本发明的起重机能够在有限空间内平稳、灵活、高效吊装作业,解决已有汽车吊操作不够方便,转场不够灵活,履带吊庞大笨重无法适应隧道、深基坑和房建等施工区域灵活吊装作业的问题。
