T140-2推土机是在T140-l推土机的基础上。在外部造型、动力性能、经济性能、排放、操纵舒适性能、驾驶环境等方面进一步提升,开发而成的T140-l推土机的升级产品。它既承袭了T140-1推土机可靠的底盘和效率高、维修保养方便等的特点,又克服了原发动机排放高、油耗大、司机操纵舒适性差的缺点,同时在外观造型、操作的舒适性、驾驶室的内饰诸方面进行改进,使其综合性能得到提高。
T140-2推土机系半刚性悬挂、机械传动、主离合器液压助力操纵、工作装置液压先导操纵、电器系统采用电子监控形式的履带推土机。可广泛用于道路修筑、水电工程、农田改造、港口建设、矿山开发及其它建筑工程项目的土石方作业。
T140-2推土机采用上柴D6114ZG5B发动机,该发动机体积小,重量轻(约 600kg),燃油消耗率低(标定工况时燃油消耗率:ge≤220×(1十5%)g/kW·h),其排放指标能够达至欧Ⅰ标准。
T140-2推土机是T140-1推土机的升级换代产品。其特点系半刚性悬挂、机械传动、主离合器液压助力操纵、工作装置油缸铰点前置液压先导操纵、电子监控、外形美观的履带式推土机,可广泛用于道路修筑、水电工程、农田改造、港口建设、矿山开发及其它建筑工程项目的土石方作业。
