What is the maximum allowable governor tripping speed for a Type A safety installed on a personnel hoist?

The maximum allowable governor tripping speed for a Type A safety installed on a personnel hoist is indeed 210 feet per minute (fpm). This specification is based on safety standards that ensure the hoist operates within limits that minimize risks to personnel.

Type A safety devices are designed to engage when the speed of the elevator exceeds a preset threshold, thus preventing potential accidents and ensuring safe operation. The specified tripping speed of 210 fpm for these safety devices has been established to account for the typical speed of personnel hoists while still allowing for effective response in an emergency situation.

Understanding these limits is crucial for maintaining compliance with safety regulations and ensuring that elevators operate safely within their designed parameters.
