摘要 |
An incline elevator with a load carrying unit running on a U-shaped track. The load carrying unit is mounted on trucks engaging the track. Below the trucks are swivelably mounted eccentric safety devices, with roller guides spring loaded against the interior walls of the channel, and eccentric brakes retracted during normal operation or extended during emergencies like a break in the elevator hoist cable. The eccentric brakes are retracted when both mechanically and electrically driven linkages are engaged. The brakes are retracted when tension is present in the hoist cable, and when electrical speed sensors sense an underspeed condition. The eccentric brakes deploy when either there is a hoist cable break, an overspeed condition, or an incline elevator power failure. The eccentric brakes are spring loaded to swing out, engaging the interior walls of the channel of the track, and jam in position stopping the load carrying unit. |
