A building site device includes a climbing formwork platform for the floor-by-floor production of concreting portions of a building core having at least one elevator shaft. An elevator system has an elevator machine platform vertically movable in the elevator shaft. In order to minimize the use of lifting cranes and the manual raising of supporting structures, the elevator machine platform can be moved jointly with the climbing formwork platform.

A threshold drain system for redirecting water entering an elevator shaft at an opening thereof is provided. The threshold drain system may include a catch channel and a sill plate. The catch channel may include a forward wall connectable to an interior wall of the elevator shaft along and below the threshold. The sill plate extends from a rearward wall of the catch channel and is offset rearward relative to at least a portion of a vertical surface of the finished floor facing the elevator shaft to define a rearward offset. The forward wall may include a flange extending from an upper end of the forward wall at an elevation lower than a bottom of the sill plate so as to define a vertical offset. The rearward offset and the vertical offset at least in part define a passageway configured to direct the water into the catch channel.

A jumping elevator system and a jumping method used in construction process of building. The jumping method includes preliminarily positioning and mounting, by means of a temporary working platform at a first height, a guide rail on the hoistway substantially corresponding to the first height; removing the temporary working platform from the position, corresponding to the first height, of the hoistway; lifting, by use of a lifting assembly, a jumping platform from a second height to a third height, wherein the third height is greater than the second height and less than or equal to the first height; and lifting, by use of the lifting assembly, the elevator car to extend its traveling distance in the hoistway, and operating, during lifting of the elevator car, on the top of the elevator car for reinforcing the mount of the guide rail.

A method for mounting and aligning a guide rail in an elevator shaft of an elevator system, which elevator shaft primarily extends in a main extension direction, includes at least the following steps: securing a rail bracket base to a shaft wall of the elevator shaft; applying a mark to the rail bracket base; aligning the guide rail in relation to the mark; and securing the guide rail to the shaft wall using the rail bracket base. The alignment of the guide rail is carried out by an alignment device that includes an abutment part and a location device.

A car safety supervising unit (SSU) for an elevator having an elevator car displaceable within an elevator shaft includes at least one sensor for sensing car-related parameters and outputting corresponding car-related signals, an I/O interface for inputting input signals into the car SSU and for outputting output signals to external devices and a signal processing unit for processing at least one of the car-related signals and the input signals and for generating the output signals. In an installation operation mode, the signal processing unit processes exclusively the car-related signals and generates the output signals based exclusively on the car-related signals whereby the car SSU accomplishes basic safety functions for safely operating the elevator with a limited number of available sensors. In a normal operation mode, the signal processing unit processes both the car-related signals and the input signals and generates the output signals based on both.

The invention relates to a construction arrangement of an elevator, comprising a hoistway formed in a building, the hoistway comprising at least one hoistway opening leading in horizontal direction out from the hoistway, the opening being delimited by a lower edge structure and an upper edge structure; and a load in the hoistway lower than said opening; and a hoisting arrangement for hoisting said load, wherein said hoisting arrangement comprises a support structure mounted higher than said load; and a hoisting device; and at least one flexible tension member connected or at least connectable to said load; wherein the at least one flexible tension member is movable with said hoisting device in particular for thereby transmitting a hoisting force to said load to be hoisted. Said support structure comprises an anchoring beam structure comprising a lower end engaging the lower edge structure, and an upper end engaging the upper edge structure; and a support beam structure connected to the anchoring beam structure and protruding from the anchoring beam structure into the hoistway; and wherein said at least one flexible tension member hangs in the hoistway supported by the support beam structure. The invention also relates to a method implementing the construction arrangement.

The present invention relates to a method and a system of commissioning elevator, and an elevator system. The method includes obtaining at least one operation data of at least one elevator door, comparing the operation data with corresponding criterion operation data, and determining whether a deviation between the operation data and the criterion operation data exceeds a pre-set range, and if so, triggering a control over at least one control end relevant to the operation of the elevator door to make a deviation between the operation data re-obtained and the criterion operation data fall within the pre-set range. The invention will increase the efficiency in elevator commissioning and remove the adverse effects on elevator operation caused by factors such as “Stack Effect”, and thereby ensure good working condition and high security of elevators.
