Elevator Safety Block By Aarti Industries

The elevator safety block provides an ultimate stop mechanism in the event of an emergency, such as excessive speed or suspension rope breakage. Traditional elevator safety blocks may be configured with a wedge principle of operation. In the case of safety actuation, as described above, a wedge or roller is configured to move upward within a frame of the elevator safety block and catch and frictionally engage with a guide rail to thus stop an elevator car or counterweight. Once engaged, after an emergency is resolved, the elevator safety block must be disengaged to enable the elevator car or counterweight to operate properly. To disengage the wedges or rollers of the elevator safety block, an upward force must be applied to release the pressures and forces on the wedges or rollers, and thus release them from engagement with the guide rail.
