CBS Show 'VEGAS' -- The Set Was A Death Trap

The set of former CBS show 'Vegas' was full of dangerous and defective equipment ... according to a lawsuit filed by an outraged crew member who nearly lost a finger.

Andrea Krout is rolling the dice and suing the drama's crane manufacturer and distributor -- Technovision and Crane Shot -- after having her thumb crushed and nearly torn off during a horrific crane accident last year while she worked as a dolly grip.

Krout says both companies are responsible for the faulty equipment and putting her life at risk -- she's demanding they pick up the tab for her medical expenses and pain and suffering.
