BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention particularly relates to an elevator in which a load detector and a load display are provided in the car and the landing.

0003

[Prior Art] Conventionally, elevators have been provided with a display section above the operation panel inside the car that shows the maximum number of passengers and the rated load. When a car is brought in, a warning buzzer or bell is used to notify passengers and the person carrying it in, and a safety device is installed to prevent the car door from closing.

0004

[Problem to be Solved by the Invention] In an elevator equipped with such a safety device, overload cannot be detected until the alarm buzzer sounds, so passengers who have boarded the elevator must come out to the landing floor until the buzzer stops sounding. Must be. However, this is fine if there are only passengers, but when using a forklift to bring luggage into the car in a freight elevator, for example, you will notice it only after lowering the luggage from the forklift's claws onto the floor of the car. must be picked up and retreated. If this load is close to the rated carrying capacity of the car, the sum of the load of the baggage already carried into the car,
There is also the risk that the main rope that hangs the car will stretch, causing the car's threshold to fall, making it impossible for the forklift's claws to enter. Then, if the load that has been taken down from the claw cannot be disassembled, the forklift cannot carry it out or even partially carry it out, so the work of transporting the load must be stopped.

Furthermore, if the forklift driver accidentally drives the front wheels of the forklift into the car, there is a risk that the forklift will not be able to move out due to the above-mentioned level difference between the threshold and the landing floor. Therefore, the purpose of the present invention is to
To obtain an elevator capable of easily notifying a boarding hall or a person carrying in luggage in advance whether or not boarding or carrying the luggage is possible. [Structure of the invention]
