Scissors Jack

Description

Scissor Jack.

The Scissor Jack is a mechanical lifting device engineered for passenger vehicles, SUVs, and light trucks. Utilizing a folded linkage design (a mechanical trapezoid), it converts a small rotational force applied to its threaded shaft into a powerful vertical lift, making it an essential, compact tool for emergency roadside tire changes.

Key Features & Specifications.

• Lifting Mechanism: Threaded lead screw driving a mechanical linkage (scissor arms) that expands and contracts uniformly to raise or lower the vehicle load.
• Material Construction: Heavy-duty stamped carbon steel or alloy steel designed to provide high structural rigidity and load-bearing stability.
• Capacity Options: Commonly available in weight ratings ranging from 1.5 tons to 3 tons, accommodating everything from compact hatchbacks to mid-size SUVs.
• Lift Height Range: Features a low collapsed profile to slide easily under low-slung chassis, with an extended height sufficient to clear standard tire replacements off the ground.
• Operation: Operated via a manual crank handle or lug wrench adapter (typically utilizing a hook or ratchet mechanism) for smooth, controlled lifting with minimal physical effort.
• Base Plate: Wide, stable steel base plate designed to distribute weight evenly and prevent sinking on asphalt or gravel surfaces.
