    • An apparatus for moving an elongate component within or through a sidewall of a pit, including a frame, a lever arm pivotably attached to the frame and comprising a handle at a first end, a gripping arrangement pivotably attached to the lever arm at a second end at a gripping pivot point, allowing the gripping arrangement to pivot about the gripping pivot point to assume a first and a second installation position, wherein in a first installation position during use the gripping arrangement grips the elongate component as the lever arm pivots in a first direction and releases the elongate component as the lever arm pivots in a second, opposite, direction, and wherein in a second installation position during use the gripping arrangement releases the elongate component as the lever arm pivots in a first direction and grips the elongate component as the lever arm pivots in a second, opposite, direction.
    • 一种用于将细长部件移动到凹槽的侧壁内或通过凹槽的侧壁内的装置,包括框架,可枢转地附接到框架并且在第一端处包括手柄的杠杆臂,在第二端可枢转地附接到杠杆臂的夹紧装置 在夹持枢转点处,允许夹持装置围绕夹持枢转点枢转以呈现第一和第二安装位置,其中在使用期间的第一安装位置中,当杠杆臂以第一和第二安装位置枢转时,夹紧装置夹紧细长部件 方向并且当杠杆臂以第二相反的方向枢转时释放细长部件,并且其中在使用期间的第二安装位置中,当杠杆臂沿第一方向枢转并且将细长部件作为第一方向旋转时,夹持装置释放细长部件, 杠杆臂以第二相对的方向枢转。
