PRODUCT DETAILS

A screw jack is a mechanical lifting device that utilizes the principle of screw transmission. It converts rotary motion into linear lifting motion by manually driving a ratchet wrench or crank, thereby lifting, lowering, or moving heavy objects. It is renowned for its reliable self-locking mechanism, extremely high positioning accuracy, and powerful load-bearing capacity, making it an indispensable basic tool in industrial production and engineering construction.
