千斤顶千斤顶jack顶举重物的轻小型起重设备，物料搬运机械。结构简单，起重量范围大，顶举高度一般不超过400毫米，广泛用于设备检修和安装。按结构特征可分为：①螺旋千斤顶。由人力通过螺旋副转动，以螺杆或螺母套筒作为顶举件，能长期支持重物，最大起重量达100吨，应用广泛。下部装上水平螺杆后，还能使重物做小距离横移。②齿条千斤顶。由人力通过杠杆和齿轮带动齿条顶举重物，也能长期支持重物，效率较螺旋千斤顶高，最大起重量达20吨，多用于作业条件不方便或需要利用其下部的托爪提升重物的场合，如铁路起轨和顶起要修理的汽车等。③液压千斤顶。由人力或电力驱动液压泵，通过液压系统传动，用缸体或活塞顶起重物。不宜长期支持重物（防止液体泄漏），最大起重量可达750吨，传动效率较高，多用于起升或移动钢结构、钢桥的梁以及船厂、锅炉厂、机械厂中的重物等。千斤顶
