20100051392 | ELEVATOR PIT BARRIER - An elevator installation includes a car within a shaft, a buffer mounted in a pit of the shaft and a barrier located in the pit surrounding or within an area wherein a vertical clearance between the pit floor and the car or equipment mounted thereon is less than a regulatory threshold value when the car fully compresses the buffer. The barrier acts to physically deter personnel within the pit from inadvertent presence in the area of reduced vertical clearance. | 03-04-2010 |
20110283814 | APPARATUS FOR PERFORMING A LOADING TEST IN AN ELEVATOR SYSTEM AND METHOD FOR PERFORMING SUCH A LOADING TEST - An apparatus and method for performing a load test in an elevator installation having an elevator car and a counterweight, which are connected to one another by a supporting device, and a drive brake for halting the elevator car during a downwards journey. The apparatus has a connecting element for fastening to the counterweight, an element with spring properties and a tensioning device for installation in the elevator installation. One point of the tensioning means is fixed to a stationary point of the elevator installation via the element with spring properties. Another point of the tensioning means is connected to the counterweight via the connecting element, wherein the tensioning device includes an actuating device with which to tension the element with spring properties in order to thereby exert a downwardly directed tensile stress on the counterweight. | 11-24-2011 |
20120031712 | FIRE SERVICE ELEVATOR - A fire service elevator with an elevator cage includes a cage roof, wherein the elevator cage is at least partly supported and driven by at least one support means. The elevator cage has on the cage roof a region vulnerable to spray water, and this region vulnerable to spray water is covered by an element having a surface structure of such a kind that extinguishing water falling on the element in the event of fire is substantially prevented from spraying in the direction of the at least one support means. | 02-09-2012 |
20120255814 | FIRE SERVICE ELEVATOR - A fire service elevator includes an elevator cage with a cage roof, wherein the elevator cage is at least partly supported and driven by at least one support device, wherein the elevator cage is looped under by the at least one support device, wherein the elevator cage has a protective element, which is arranged at least partly around the at least one support means and disposed substantially on the cage roof. The protective element screens the at least one support device relative to a central region of the cage roof so that extinguishing water falling onto the cage roof in the case of fire is substantially prevented from wetting the at least one support device. | 10-11-2012 |
20120255816 | ELEVATOR SYSTEM HAVING A CAR-SIDE EXTINGUISHING WATER DRAIN SYSTEM - A drain system, in an elevator system having at least one elevator car with an upper edge running approximately parallel to a horizontal plane, includes a deflector plate arranged on the upper edge of the elevator car at at least one angle of inclination to the horizontal plane and inclined against a shaft wall in which shaft doors are arranged, so that extinguishing water, which falls onto the elevator car is directed at least partially from the deflector plate against the upper edge and against the shaft wall in which the shaft doors are arranged. | 10-11-2012 |
20120266968 | ELEVATOR SYSTEM HAVING A SHAFT-SIDE EXTINGUISHING WATER DRAIN SYSTEM - A drain system, in an elevator system, is an open system wherein extinguishing water penetrating through a shaft door sill having bores meets a catch plate arranged underneath the shaft door sill and can be substantially discharged along at least one shaft wall. | 10-25-2012 |
20120325582 | FIRE SERVICE ELEVATOR - A fire service elevator includes an elevator cage with a cage roof, a first side wall and a second side wall. The elevator cage is at least partly supported and driven by at least one support. The elevator cage is looped under by at least one support so that the at least one support runs along the two opposite side walls. The fire service elevator is designed so that the elevator cage in an operating state reaches speeds of more than 1 meter per second. The elevator cage includes at least one protective element which is arranged substantially above a side wall so that extinguishing water falling onto the cage roof in the case of fire is substantially prevented from wetting the at least one support means. | 12-27-2012 |
20120325592 | ELEVATOR WITH COMPENSATING DEVICE - An elevator includes a compensating device having the purpose of providing compensation for changing weight of a support on the cage side or on the counterweight side. Depending on the respective position of an elevator cage and a counterweight in the elevator shaft there are more meters of the support on the cage side or on the counterweight side. In the case of a small support length on the cage side, a large compensating device length on the cage side results and conversely. The compensating device suspended at the elevator cage and at the counterweight forms a loop in a shaft pit and can be set in oscillation. Provided as a remedy are, for example, rods which guide and stabilize the compensating device. | 12-27-2012 |
20130037354 | FIRE SERVICE ELEVATOR - A fire service elevator has an elevator cage, which includes a cage roof, wherein the cage roof has a seal in which at least one drain is arranged. The drain is so arranged in the seal that extinguishing water collecting on the cage roof in the case of a fire flows away from the cage roof substantially only via the drain. | 02-14-2013 |
20130092479 | ELEVATOR - A car for an elevator, which is movable in an elevator shaft, has a car roof projecting at least partly beyond a drive unit. Arranged on the car roof in the region of the side facing the drive unit is a balustrade which has a handrail interrupted centrally in a drive receiving region. The balustrade has in the drive receiving region a bar which is arranged to be offset downwardly and inwardly relative to the handrail. | 04-18-2013 |
