    挖掘机伸缩臂说明:
       地铁在施工的过程中要进?#26800;?#19979;的开挖,当地下施工要求达到一定深度时,普通挖掘机的挖掘深度已经无法满足要求,加长臂的挖掘机因臂的长度增加使得斗容变小,速度变慢。目前加长臂的长度只有18米且效率不高,小松-220SC弥补了这些缺陷,最少20米下挖深度,一个工作回合(从抓土到放土入车)约45秒,一个斗能容0.8立方,无论在速度上还是效率上?#21152;?#32477;对的优势,是地铁下挖的首选。
    ?#35270;?#25366;掘机品牌:卡特CAT、小松PC、日立EX(ZAX)、神钢SK、大宇(斗山)DH、现代R、加藤HD、凯斯CX、住友SH、沃尔沃EC、柳工、玉柴、三一、徐挖、邦立等挖掘机系?#23567;?BR>使用原理:
    伸缩臂挖掘机,包括与斗杆相连的上滑动臂及上滑动臂上端设置的斗杆液压油缸,其特征在于:
    1)伸缩臂由上滑动臂与下定臂两部分构成,上滑动臂安装在下定臂上方,两者通过上滑动臂两侧滚轮及道轨与下定臂两侧滚轮及道轨相互配合上下连为一体,上滑动臂可以在下定臂上部通过伸缩油缸作?#20204;?#21518;自由伸缩。
    2)上滑动臂内装伸缩油缸,伸缩油缸的缸体固定在下定臂上,伸缩油缸动?#26031;?#23450;在上滑动臂上。本实用新型具?#24515;?#22815;随时调整伸缩臂伸缩性,适当调整挖掘深度,而且结构简单,易于操作,?#35270;?#22823;范围的推广应用
