1. When working, the claw slips, resulting in a safety accident.
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 load of the puller is unbalanced, which leads to the fracture or straightening of the screw and jaw, thus causing 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.
◆ Automatic centering, preventing unbalanced load, ensuring that the screw is always in the stress center, and prolonging the service life.
◆ Quickly control the puller through the T-handle and safety cage, which is more convenient to operate.
◆ 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.
Special-shaped jaws are more conducive to narrow space operation.
Generally speaking, tonnage, telescopic distance and telescopic distance are important basis for hydraulic horse selection. The USA POSILOCK has the following models for you to choose from: claw number, tonnage, ton extension, millimeter extension, millimeter cylinder oil quantity, cubic centimeter weight, and kilogram pH1063515217837.5 pH108310200. 4 226 1 1 ph 10 3 15 245 38 1 5 16 23 ph 1 13 3 25 304 457 1202 48 ph 1654 38+06 3 50 355 655
