Abstract
An elevator system (1, 1′) includes a portable emergency stop switch (2, 2′), arranged to transmit a signal (4) when activated, a signal receiver (6, 6′), arranged to receive the signal (4, 4′) transmitted by the portable emergency stop switch (2, 2′); and an elevator safety actuator (8, 8′) and an elevator safety brake (10, 10′). In response to receipt of the signal (4, 4′), the signal receiver (6, 6′) is arranged to trigger the elevator safety actuator (8, 8′) to deploy the elevator safety brake (10, 10′).
Claims13
An elevator system (1, 1′) comprising:
- a portable emergency stop switch (2, 2′), arranged to transmit a signal (4) when activated;
- a first signal receiver (6, 6′), arranged to receive the signal (4, 4′) transmitted by the portable emergency stop switch (2, 2′);
- an elevator safety actuator (8, 8′) and an elevator safety brake (10, 10′), wherein in response to receipt of the signal (4, 4′), the first signal receiver (6, 6′) is arranged to trigger the elevator safety actuator (8, 8′) to deploy the elevator safety brake (10, 10′);
- and
- a second signal receiver (26) arranged to disconnect a power supply to an elevator car and/or to an elevator drive system in response to the receipt of the signal (4, 4′).
A method of deploying an elevator safety brake (10, 10′) by service personnel, comprising:
- activating a portable emergency stop switch (2, 2′) by the service personnel;
- transmitting a signal (4, 4′), by the portable emergency stop switch (2, 2′), in response to activation of the portable emergency stop switch (2, 2′);
- receiving the signal (4, 4′) with a first signal receiver (6, 6′) and a second signal receiver (26);
- triggering of an elevator safety actuator (8, 8′) to deploy the elevator safety brake (10, 10′), in response to the receipt of the signal (4, 4′) by the first signal receiver (6, 6′);
- and
- disconnecting a power supply to an elevator car and/or to an elevator drive system, in response to receipt of the signal (4, 4′) by the second signal receiver (26).
