The elevator car is characterized by being provided with: the left and right connecting part side plates and the intermediate side plate, edge parts thereof being formed from a plate material having a U-shaped cross-section that reaches a folded part from a surface part via a side part; height-direction plates fixed to the folded parts of the left and right connecting part side plates and extending toward the intermediate side plate side; protrusions provided to either the folded parts of the intermediate side plate or on extending portions of the height-direction plates, the extending portions extending towards the intermediate side plates; and locking parts provided to the other of the folded parts and the extending portions. The elevation car is further characterized by the intermediate side plate being installed between the left and right connecting part side plates via the protrusions locking to the locking parts.
An elevator apparatus provided with a passenger car; a counterweight; a hoist for driving the lifting and lowering of the passenger car and the counterweight; a machine base for supporting the hoist; and a machine beam for supporting the machine base; wherein the elevator apparatus has an extension section extending from the machine base to the passenger car side, and a stopper plate attached to an end section of the extension section, wherein the stopper plate is sandwiched between two horizontal vibration control rubber parts, and wherein the stopper plate and the two horizontal vibration control rubber parts are sandwiched between two brackets. Due to this configuration, the present invention is able to provide a hoist assembly that collects the horizontal vibration control structure for the hoist of the elevator apparatus on the car side.
Provided is passenger conveyor equipment for which a new passenger conveyor is installed by using an existing body frame of an existing passenger conveyor, wherein the new body frame can be prevented from falling even when the building structure is experiencing large vibrations due to a large earthquake or the like. To this end, on at least one end of the passenger conveyor equipment, an existing equipment side bearing beam (7A) that is provided on an end of an existing body frame (2) is placed on a construction beam (9) of a building structure so as to be mutually movable with respect to the construction beam (9), and a new equipment side bearing beam (13A) that is provided on an end of a new body frame (10) is placed on the construction beam (9) and the existing equipment side bearing beam (7A) so as to be mutually movable with respect to the construction beam (9) and the existing equipment side bearing beam (7A). At least a portion of at least one of a driving device (21) and an electrical panel (20, 20A) is disposed in a gap between the existing body frame (2) and the new body frame (10).
Provided are a riding basket and an elevator apparatus with which flexibility of an installation position of an ion generating apparatus may be improved by requiring no adjustment in the size of the riding basket and preventing interference with another apparatus in installing the ion generating apparatus. According to the present invention, the riding basket and an ion generating apparatus (15) of the elevator apparatus are fixed to a plate body (18) which is larger than the ion generating apparatus (15), and the ion generating apparatus (15) is positioned in a space (25) and fixed from a rear surface side opposite to the space (25) of an in-ceiling frame (13) through a notch hole formed at the in-ceiling frame (13), the notch hole being larger than the ion generating apparatus (15) and smaller than the plate body (18).
[PROBLEMS] To provide a safety system of an elevator in which the position of a cage in the vertical direction can be detected conveniently with high reliability, and landing error between the cage and a floor can be detected at a plurality of levels. [MEANS FOR SOLVING PROBLEMS] The safety system of an elevator comprises a plurality of detection bodies (17, 18, 23, 24) arranged on the same vertical line in an elevator shaft, and a plurality of detectors (13, 14) provided in the cage (1) to oppose each pair of detection bodies, wherein the position of the cage in the vertical direction, e.g. landing error between the cage and a floor, is detected at a plurality of levels based on a plurality of output signals from the detectors. Furthermore, validity of opposing detection by detection bodies and detectors is judged based on the cage position information from second cage position detecting means (8, 9) for detecting the position of the cage in the vertical direction equivalently or measurement information on an elapsed time or a moving distance from opposing detection of a detection body by a detector to opposing detection of the next detection body.
A security system with processing optimized for monitoring the actions of a surveillance subject and detecting abnormal actions. The action record of an individual is monitored using a sensor network security system SNS, and the development of an action event is reported as an action, and the corresponding processing of the security system SCS is determined based on this action.
