2. The eccentric load of the puller causes the screw to bend and get stuck in the hollow cylinder, which is a dilemma.
3. The eccentric load of the puller causes the screw and jaw to break or straighten, which leads to safety accidents.
4. The stroke of the oil cylinder is too short, and it needs multiple positioning to complete the work, which increases the workload for no reason.
1978 American Poselock Company invented the safety cage self-locking and self-centering horse, and American Poselock self-locking and self-centering hydraulic horse is equipped with a long-stroke hydraulic cylinder with spring retraction. When in use, as long as the corresponding manual pump or electric pump is connected, the thick plunger of the air cylinder directly acts as a lead screw, which stably acts on the pulled workpiece, thus completely avoiding the above problems. Its main features are as follows:
Unique patent design of safety cage can completely lock the workpiece, prevent it from slipping, and make the work safer.
◆ No wire rod design, the plunger of the long-stroke oil cylinder directly acts on the stretched workpiece, which makes the operation simpler and safer.
◆ 3/8NPT quick connector can be used for various 700bar/ 10000psi hydraulic systems.
