Lifting Jacks

Lifting jacks are used for leveling or positioning heavy equipment, or for supporting structures. They use screw or cylinder-based actuators and are powered by hydraulic, mechanical, electric, or manual methods. Typically, the lifting element is described as either a shoe or a saddle. Many different types of lifting jacks are available. Product specifications to consider include lift capacity, lift stroke, minimum height, and maximum height. Lift capacity is the maximum lift force. Lift stroke is the difference between the fully-retracted and full-extended positions of the lifting jack. Minimum height is the distance from the jack base to the lifting element in the fully-retracted position. Maximum height is the distance from the jack base to the lifting element in the fully-extended position.
