摘要：
将储存尿素水溶液的尿素水箱(28)设置在手容易从周围到达的回旋机架(6)的右前部的实用室(6G)内。该场合，采用使构成工作油管道(18)的一部分并向作业装置(5)的起重臂液压缸(5D)供给和排出工作油的作业装置用管道(21)的中途部位沿着尿素水箱(28)的外面配置的结构。因此，即使在周围没有成为热源的部件的场所配置尿素水箱(28)，也能够使用在作业装置用管道(21)内流通的工作油的热将尿素水箱(28)内的尿素水溶液从周围稳定地加温。并且，尿素水箱(28)可配置在作业容易的位置，从而能够容易进行尿素水溶液的填充作业、维修作业等。
摘要（英）：

A urea water tank (28) for containing urea water solution is provided in a utility chamber (6G) placed at a position located at front right of the rotation frame (6) and easily accessible by hand from the periphery. In this arrangement, an intermediate portion of work device piping (21) that is a part of hydraulic oil piping (18) and supplies and discharges hydraulic oil to and from a boom cylinder (5D) of a work device (5) is laid along the outer surface of the urea water tank (28). This means that, even if the urea water tank (28) is installed at a place around which there is nothing functioning as a heat source, the urea water solution in the urea water tank (28) can be stably heated from around the tank by heat of the hydraulic oil flowing in the work device piping (21). Further, the urea water tank (28) can be installed at a place where a worker can easily work, and this facilitates filling of the tank with the urea water solution, maintenance work, etc.
