⚙️ Rack-and-Pawl Jack for Multi-Position Lifting

This rack-and-pawl mechanical jack is designed to provide controlled vertical lifting and stable support through a self-locking ratchet mechanism. As the handle moves up and down, the internal pawl engages the toothed rack step by step, allowing the lifting head to rise gradually while helping prevent reverse movement under load.

Its adjustable multi-position design allows the support height to be configured for different lifting situations, making it useful for vehicle maintenance, trailer support, cargo stabilization, equipment servicing, and other heavy-duty applications. The removable extension section increases working flexibility across lower and higher lifting ranges, while the wide steel base helps improve stability on uneven ground surfaces.

Unlike hydraulic systems, this mechanical lifting design operates without fluid pressure or external power sources, relying instead on manual leverage and mechanical locking for controlled support and load holding during maintenance or repair tasks.
