Claims17
An elevator system, comprising:
- an elevator car movably mounted within a hoistway;
- a machine operatively connected to the passenger car and capable of moving the elevator car within the hoistway;
- and
- a power source mounted within the hoistway and operatively connected to the machine, the power source configured to supply power to the machine, wherein the supplied power is sufficient to move the elevator car under normal operating conditions.
The elevator system of clam 3, wherein the bedplate is hollow, and the power source is mounted within the bedplate.
An elevator system, comprising:
- a plurality of rails configured to be mounted in a hoistway;
- an elevator configured to be movably mounted on at least one of the rails;
- a counterweight configured to be moveably mounted on at least one of the rails;
- a bedplate configured to be connected to the rails at a top of the hoistway;
- a machine configured to be mounted to the bedplate and configured to be operatively connected to the elevator car;
- and
- a power source configured to be mounted on the bedplate and configured to be electrically connected to the machine, wherein the power source is configured to provide power to the machine, and wherein the provided power is sufficient to drive the machine during normal elevator operation.
A method comprising:
- movably mounting an elevator car within a hoistway;
- mounting a machine within the hoistway;
- and
- mounting a power source within the hoistway, wherein the machine is configured to be powered exclusively by the power source during normal operation.
The method of claim 16, further comprising mounting the machine and an inverter on the bedplate.
