YTQH400型强夯机是宇通重工自主研发的一种全回转、多节桁架臂组合、全液压驱动的履带式强夯机,现广泛应用于工业与民用建筑、仓库、路基、机场及码头等地基处理的强夯作业。该型强夯机在作业中曾发生臂架腹管开焊故障,为此进行了深入研究和改进。1.臂架结构该型强夯机臂架结构如图1所示。为满足强夯的承载能力,同时考虑减轻臂架自身质量和防止臂
YTQH400 tamping machine is a fully rotary, multi-section truss arm combination, fully hydraulic crawler tamping machine independently developed by Yutong Heavy Industries. It is widely used in industrial and civil buildings, warehouses, subgrade, airports and wharfs and other foundations Dynamic ramming operation. This type of tamping machine occurred in the operation of the boom tube open tube welding failure, for which conducted in-depth study and improvement. 1. Boom structure This type of rammer boom structure shown in Figure 1. To meet the carrying capacity of dynamic compaction, while taking into account to reduce the quality of the boom itself and to prevent the arm
