Compact scissor lift

A scissor mechanism offers a compact way to raise a platform. Its changing geometry makes the required actuator force and joint loading vary throughout the stroke.

This is an illustrative project preview. It introduces the questions a full design study would need to answer; no payload, safety rating, or tested performance is claimed.

The design would be evaluated over its whole travel, with attention to low lift angles and the way forces pass through the arms, pins, supports, and platform.

• Define load cases, lift range, and footprint.
• Establish the geometry and actuator arrangement.
• Check arm buckling, pins, and interfaces.
• Assess platform stability and travel limits.
