Abstract:
In an elevator, preferably one without machine room, a hoisting machine engages a set of hoisting ropes via a traction sheave, said set of hoisting ropes having a load-bearing part twisted from steel wires of circular and/or non-circular cross-section, and in which elevator the hoisting ropes support a counterweight and an elevator car moving on their tracks. The weight of the hoisting machine of the elevator is at most about 1/5 of the weight of the nominal load of the elevator.
Abstract:
The invention relates to an elevator car (1) equipped for automatic reception and delivery of goods ordered to the home door via electrical commerce, the aforesaid elevator car (1) comprising an intelligent set of goods transport cases (2) which are used for transporting the ordered goods to the home door under control of data system (80) of the elevator after the aforesaid goods have arrived. This arrangement provides the advantage of minimizing the logistics gap between the placement of an order and the delivery of the goods.
Abstract:
A rope load detecting device (2) for detecting total rope load in multiple elevator ropes (1), comprises a frame (21) held on the multiple elevator ropes, and a force sensing element (22). The frame includes a tension beam (211), a first and second connecting bars (212, 213), a movable member (214) and a supporting beam (215), one end of the first and second connecting bars is fixed to the tension beam, the other end is fixed to the supporting beam, one end of the movable member is connected to the tension beam, the other end freely passes the supporting beam. Wherein, the frame is configured to enable the part of each elevator rope passing through the first and second connecting bars and the movable member of the frame to be bent, enabling the force caused by each loaded elevator rope to act on the force sensing element by means of the movable member of the frame, whereby the total rope load in multiple elevator ropes can be detected by a single force sensing element.
Abstract:
The present invention presents a method and a system for the positioning of the elevator car and the door of the elevator in the condition monitoring system. In the method the accelerations of the elevator car and the door of the elevator are measured with sensors. By integrating the acceleration information two times in relation to time the position information is determined. When the condition monitoring system detects a fault, forecasts a malfunction occurring in the future or detects a significant change in the operation of the elevator or in the measuring signals related to the elevator, it is possible to attach to this information the location of the fault or event i.e. the position of the elevator or the position of a door of a certain floor level on the slide path. The position information can be synchronized to a separate reference point by means of a positioned switch by making an adjustment to the position information at the reference point . The measuring error caused by the misalignment of the position of the acceleration sensor is compensated for either with electronics or using a program.
Abstract:
In an elevator, preferably one without machine room, a hoisting machine (6) engages a set of hoisting ropes (3) via a traction sheave, said set of hoisting ropes having a load-bearing part twisted from steel wires of circular and/or non-circular crosssection, and in which elevator there is diverting pulleys (9, 4) of which some is made larger than traction sheave. The weight of the hoisting machine of the elevator is at most about 1/5 of the weight of the nominal load of the elevator.
Abstract:
The invention relates to a method for repayment of the investment costs of an elevator on the basis of personal identification of the passenger, by providing the aforesaid passenger with a card comprising the personal data of the aforesaid passenger, on the basis of which card a remote reader installed in connection with the elevator identifies the passenger.
Abstract:
The invention relates to an elevator arrangement having an elevator comprising an elevator car (1) having a floor (8) and a roof (7). The elevator car (1) is provided with one or more extension spaces (13) which are arranged to extend the height of the elevator car (1) during construction time use.
Abstract:
In the invention a method is presented for ensuring operating safety in an elevator system, an elevator system, and a safety device of an elevator system. The elevator system comprises at least an elevator car, elevator ropes, an elevator motor, a traction sheave and at least two holding brakes, which holding brakes are arranged to prevent movement of the elevator car when the elevator is stopped. According to the invention the first holding brake is engaged at the end of an elevator run, and the other holding brakes are engaged with a delay. When one holding brake is engaged, the state of motion of the elevator and any slipping of the brake is monitored. If the brake is detected as slipping, a procedure for preventing a hazardous situation is performed.
Abstract:
A counterweight and an elevator car are suspended on a set of hoisting ropes. The elevator comprises one or more rope pulleys provided with rope grooves, one of said pulleys being a traction sheave driven by a drive machine and moving the set of hoisting ropes. At least one of the rope pulleys is provided with a coating bonded to the rope pulley and containing the rope grooves, said coating having a thickness that, at the bottom of the rope groove, is substantially less than half the thickness of the rope running in the rope groove and a hardness less than about 100 shoreA and greater than about 60 shoreA. In a preferred solution, the traction sheave is a rope pulley like this.
