| 自锁式液压千斤顶 |
自锁千斤顶的设计是液压原理与机械原理的完美结合，在活塞杆整个冲程范围内都有螺纹，完全顶升后，可将止退挡圈旋下，直至顶住缸体，由止退挡圈及缸体受力，从而可以撤去油泵，实现千斤顶的自锁，特别适用于砼梁及砼桥的持续支撑及测试作业。螺母自锁使负载更安全，能经受住偏载荷达千斤顶额定承载能力的10％，溢流孔兼有限制行程的功能，它主要适用于发电厂、石油化工、机械制造安装以及曲线桥定位的机械锁定，该产品具有体积小、使用方便、操作灵活、工作省力、携带方便、节省安装时间、提高工作效率等特点。
自锁式液压千斤顶特性：
用于提升和机械负荷支撑。
螺纹活塞有耐磨镀层，缸体内壁镀硬铬。
绝对机械式锁定负载。
高温烤漆表面耐腐蚀及撞击。
千斤顶起升到指定高度，旋下锁定螺母即可撤去泵站，从而实现长 时间支撑负荷作业。
