Collision avoidance system for scissor lift
First Claim
1. A scissor lift, comprising:
- a passenger basket;
a base, comprising wheels;
a scissor extension mechanism between the passenger basket and the base, the scissor extension mechanism being configured to raise the passenger basket in a first direction relative to the base and lower the passenger basket in a second direction, opposite the first direction, relative to the base; and
a through-beam sensor system co-movably coupled to the scissor extension mechanism, wherein the through-beam sensor system moves in a third direction, perpendicular to the first direction and the second direction, when the scissor extension mechanism raises the passenger basket and moves in a fourth direction, opposite the third direction, when the scissor extension mechanism lowers the passenger basket.

Abstract
Disclosed herein is a scissor lift comprising a passenger basket. The scissor lift also comprises a base that comprises wheels. The scissor lift further comprises a scissor extension mechanism between the passenger basket and the base. The scissor extension mechanism is configured to raise the passenger basket in a first direction relative to the base and lower the passenger basket in a second direction, opposite the first direction, relative to the base. The scissor lift additionally comprises a through-beam sensor system co-movably coupled to the scissor extension mechanism. The through-beam sensor system moves in a third direction, perpendicular to the first direction and the second direction, when the scissor extension mechanism raises the passenger basket and moves in a fourth direction, opposite the third direction, when the scissor extension mechanism lowers the passenger basket.
