    • Hydraulic pliers useful for mounting and dismounting snap rings (otherwise called C-shaped stop rings) of large nominal diameter. They comprise a hand-holdable plier main body having working fluid contained therein, a hydraulic piston mechanism contained in the plier main body and adapted to be moved by hydraulic forces exerted by manual pumping operation effected by gripping action applied from outside, and a working-pin opening and closing mechanism mounted on a plier head for operative connection to the hydraulic piston and adapted to be opened or closed in the same plane and at right angles to the directon of movement of the hydraulic piston as the latter advances. The hydraulic pliers do not require any accessory equipment and are handy to carry. Thus, they are designed to expand or contract snap rings of large diameter lightly and efficiently by their hydraulic force.
    • 液压钳可用于安装和拆卸公称直径大的卡环(称为C形止动环)。 它们包括一个包含在其中的工作流体的可手握钳子主体,一个容纳在钳子主体中的液压活塞机构,并且适于由通过从外部施加的夹紧动作而进行的手动泵送操作而产生的液压力移动, 销打开和关闭机构安装在钳子头上,用于与液压活塞操作连接,并且适于在同一平面中开启或关闭,并且与液压活塞的运动方向成直角。 液压钳不需要任何附件设备,方便携带。 因此,它们被设计成通过其液压力轻且有效地扩大或收缩大直径的卡环。
