Crusher

That is not a panel. That's a crusher. We sell those too. — Cave Johnson

The Crusher is one of the many hazards that are littered about within the Apeture Science facilities. It's job is simple: To crush anyone caught between it and the nearest wall with bone-smashing force. These hazards become more frequent during the last areas of the game, especially Chapter 9, where Wheatley tries to kill you. These are also encountered several times during Co-op.

Function

Crushers operate with one function and one function only. To crush. Anything caught in its path is perforated with one of its many large, steel spikes firmly attached to the crusher. Nothing can withstand it's force, save for the structurally sound walls of the facility. Crushers generally make themselves obvious, allowing the player to move out of the way before it begins its crushing rampage. Any sort of contact with the crusher will result in an instant, messy death. During Co-op, coming in contact with these while floating in an Excursion Funnel will cause periodic damage until either the player moves away or dies.
