摘要： PROBLEM TO BE SOLVED: To prevent the buffer collision of a balance weight by allowing the stopper of a plunger to hit a cylinder before the balance weight collides with a buffer when the balance weight is lowered excessively. SOLUTION: The length of a rope 8 is set so that the stopper 41 of a plunger 4 hits a cylinder 3 to prevent the plunger from rising any more before a car 1 hits the apex of a hoistway 10 or a beam 11 when an elevator rises excessively due to some abnormality. A balance weight 2 is located at a position not to collide with a buffer 6 at this time, i.e., the length of a rope 9 on the balance weight 2 side is set so that a gap set in advance is kept between the balance weight 2 and the buffer 6 when the stopper 41 of the plunger 4 hits the upper section of the cylinder 3. Even if the elevator rises excessively due to some abnormality, the stopper 41 is prevented from hitting the car 1, and the buffer collision of the balance weight 2 can be avoided.

摘要： PROBLEM TO BE SOLVED: To realize approximately same load even when a car is located on any floor by judging the overload by an overload judging means based on the detected load or an in-car load, and changing the judged overload judging load for each floor. SOLUTION: An elevator control panel 109 inputs the detected value of the in-car load from a load detecting device 103 when a car 101 is stopped in the door zone. The detected value of the in-car load and the data registered in a load detection/ correction value register table are subtracted by an overload control part 112 of a micro-computer 110, and the obtained value is the detected value of the in-car load. The detected value of the in-car load for each floor can be obtained by setting the load detection errors in the load detection/correction register table so that the detected value of the in-car load for each floor is constant. The overload reference value and the detected load value which are calculated from the overload reference value and the data registered in the overload detection changing value table are judged for the overloading by an overload judging part 115. When the detected value is smaller than the overload reference value, the normal operation is continued. When the detected value is larger than the overload reference value, an alarm is given to prevent the start.

摘要： PURPOSE:To continue operation even when one of a plurality of power units is failed in an operation by separating a failure in operation spot from a hydraulic power unit corresponding to the failure in an operation spot or a control device for the hydraulic power unit when a failure in an operation is detected. CONSTITUTION:A motor drive signal S1 is outputted from a control device 11 to excite a relay 101a. In this case, a failure in operation detecting device 13 monitors the motor drive signal S1 and the contact of the relay 101a to decide as under-mentioned. Namely, when the contact of the relay 101a is closed, contact is normal and when the contact of the relay 101a is opened, contact is defective. In case the relay 101a is demagnetized by means of the motor drive signal S1, when the contact of the relay 101a is opened, contact is normal and when the contact of the relay 101a is closed, a contact is fused. As noted above, when a contact is poor in contact or fused, the failure in operation detecting device decides that a power unit 1 is failed in operation, a fail safe relay FS1 is demagnetized and the power unit 1 is separated.

摘要： PROBLEM TO BE SOLVED: To improve the security of waiting passengers in an elevator hall by economically reducing the opportunities of encountering a suspicious person. SOLUTION: The suspicious person in an elevator car is detected by the fact that there is no operation of an operation panel in the elevator car and the operating condition of passenger detecting means in the elevator car is continued for a preset time. When a landing call is registered in the state of detecting the suspicious person in the elevator car, a door opening button in the elevator car and a landing call button are made invalid, the opening of an automatic door is prevented when the elevator car arrives at a floor where the landing call occurs, and the waiting passengers can open the door with operating means arranged on the elevator hall. Thus, the safety of the waiting passengers on the elevator hall is improved by economically reducing the opportunities of encountering the suspicious person. The suspicious person is involved in a feel of confinement because of the call button and the door opening button being invalid, resulting in the effect of no longer intention of suspicious action.

摘要： PROBLEM TO BE SOLVED: To relieve an installation worker from burden during running-in operation. SOLUTION: An existing inspection lamp switch in a key box and car call uppermost and lowermost floor buttons are operated using code numbers to start running-in operation. The running-in operation automatically repeats floor- stop move-up/down operation and floor-end straight operation for a certain time. To prevent the getting-in of general passengers during running-in operation, response to a hall call is prohibited, announcement for guidance is prohibited and a car is lit off. After the passage of a certain time, the car is reset to the lowermost floor to finish the running-in operation. If troubles occur during running-in operation, the operation is interrupted immediately. Automatic running-in operation for a certain time gives less burden to the installation worker and saves time and expenses. Thus, the condition of the elevator can be accurately seized by the installation worker and the initial troubles can be minimized after delivery to a customer.

摘要： PROBLEM TO BE SOLVED: To prevent a counter weight rope from being loosened by traveling a car in the descending direction when a counter weight-side emergency stop device malfunctions, and releasing the emergency stop. SOLUTION: In this fluid pressure elevator having a fluid jack 4 for vertically moving a fluid plunger 2 to raise and lower a car 1 through a main rope 3, an emergency car stop device 8 is attached to the car 1, and when the car 1 lower at an abnormal speed, the abnormal speed is detected by a governor 25 to emergency stop the car 1. When a governor 35 for a counter weight 5 malfunctions in this emergency stop, an emergency stop 33 is operated. At this time, when the car 1 is traveled in the ascending direction, a counter weight rope 7 is loosened since the counterweight 5 is not moved. Thus, in the emergency stop of the elevator, the car 1 is necessarily traveled to the descending directional nearest floor to solve the looseness of the rope 7.

摘要： PURPOSE:To promote small electrification as well as to reduce a stopping shock by controlling the body of a main control valve with non-return function or a magnet coil of a pilot valve in use of a capacitor or DC power supply so far charged during current-energization, as a controlling power source after power failure, in the case where the power failure has occurred. CONSTITUTION:A main control valve DV with a non-return function serves as a check valve at time of stoppage and ascension, and magnetizes three solenoid pilot valves SDH, SDN, SDE only at the time of working, thus it is selected, discharging a fluid to a tank 1. The solenoid pilot valve SDE discharges the fluid to the tank 1 via a reduction control throttle valve 30. When a power failure has occurred at time of traveling at more than a speed V1, the valves SDE, SDH are demagnetized and the valve SDN remains demagnetized intact, and the main control valve DV is slowly closed, so that any stopping shock is thus preventable.

摘要： PROBLEM TO BE SOLVED: To provide a safety system of an elevator capable of operating the elevator without impairing safety even if a sheave is worn.SOLUTION: A safety operation system of an elevator includes a means for measuring a rotation number of a sheave 6 of the elevator 1, a means for measuring a moving distance of a car 3, and a means for calculating a wear amount of the sheave 6 from information, and when the calculated wear amount exceeds a set value, the allowable load amount, operation speed or acceleration/deceleration of the elevator 1 is limited by resetting it to a value lower than a prescribed value, and the safety of the operation is improved. Also, when a plurality of elevators 1 are provided together, the priority order of the allocation of the elevator to a call is lowered for a group management controller 10. Furthermore, when the wear amount becomes a dangerous value or larger, the elevator is stopped and the operation thereafter is inhibited.
