The new Ants digital shaft copying system from Kübler — also known as a shaft information or positioning system — is used worldwide in elevators and (in addition to the precise positioning it imparts to elevator cars) is particularly useful thanks to its simple assembly and compact design.
New generation — more mounting options
The new generation of Ants shaft copy systems brings some innovations with it. In the field of mechanical construction, more flexible mounting options are available today. The sensor is mounted directly on the elevator car by means of a mounting strap and car mounting. Depending on the space available, the sensor can be positioned at the car mounting in 90° steps. The most compact solution is to mount the sensor via the T-slot prefabricated in the sensor housing. The tangential cable outlet above the sensor housing also ensures maximum compactness.
New generation — more performance
Already with the base version of the new generation Ants shaft copying systems, absolute position values of the elevator car with a resolution of 1 mm and a travel speed of 8 m/s can be determined without slopping. The SIL3-certified safe variant with a resolution of 0.5 mm is suitable for elevator systems up to a travel speed of 12 m/s. The SIL3-certified safe variant with a resolution of 0.5 mm is suitable for elevator systems with a travel speed of up to 12 m/s. Something has also changed in the area of electrical interfaces. In addition to the CANopen Lift and SSI interfaces, the RS485 interface is now also available for the base version. The safe version continues to communicate via CAN. The new generation is UL-certified in comparison to standard systems on the market. Thanks to IP54, the system is even more robust than ever.
Exact positioning and 100% slip-free measurement
The linear measuring system from Kübler is mounted directly on the elevator car. This permanently records the absolute position, which is required, among other things, for a precise approach to the desired floor. The absolute position feedback eliminates the need for a reference run in the event of a power failure, as absolute position values with a resolution of 0.5 mm are always available over the entire conveying height of up to 392 meters. Measurement errors can occur during the continuous operation of an elevator due to vibrations and dynamic rope effects. With the direct installation of the Kübler measuring system, this is a thing of the past. A 100% slip-free measurement is guaranteed.
Robust and extremely compact
The sensor housing made of aluminum and the stainless steel band ensures reliable operation. The shaft copying system is based on a non-contact measuring principle, which is particularly wear-free, stands for long service life, and fulfills the measuring quality required in the target application. It is the most compact measuring system for absolute shaft copying (135 x 45 x 33 mm). For retrofits, modernizations, existing buildings/elevator shafts, or new installations, the system can also be used in the tightest of installation spaces without any problems.
Installation = child’s play
A unique selling point of this measuring system is its easy installation. The mounting kit consists of two mounting brackets, the rolled-up stainless steel band, and a spring element, which is required for pretensioning the band in the shaft pit. During installation, no attention needs to be paid to anything, because the stainless steel band forgives scratches or kinks that may have occurred during installation. The measuring system can be installed in a few minutes. This saves a lot of time and money. In addition, the new generation comes with a further feature: The status LED serves as a diagnostic function.
The optimum solution for every requirement
The measuring system is offered in three possible combinations with the relevant interfaces (SSI, CAN, CANopen, RS485, and CANopen Lift) of the lift industry:
Ants Base, LEB01
Ants Safe, LES02 (SIL3 certified)
Safe system, Ants safe + evaluation unit (PSU)
Implementation of elevator and safety functions according to EN 81-20/21/50
Everything from a single source: Kübler offers a complete package of functional safety technology. Based on a 100% slip-free measurement, the position values of the elevator car are reliably determined by a SIL3-certified shaft copying system and transmitted to the evaluation unit (PSU).
The safe version of the measuring system is SIL3-certified and TÜV-tested and covers a wide range of elevator and safety functions:
Inspection drive up & down, direct entry, moving the landing, unintentional movement of the car (UCM), and many more.
Elimination of additional sensors saves costs
The linear Kübler shaft copying system eliminates the need for a large number of components in the lift shaft. This considerably reduces complexity and installation time. If you imagine that in conventional elevator systems, in order to detect the absolute positions, you have to use several magnetic switches, then not only many installation hours result, but also an enormous maintenance effort as well as a complicated search in the event of a fault.
Advantages at a glance:
– Simpler installation
– Fewer components in the elevator shaft
– Reduced complexity
– Faster troubleshooting in the event of a malfunction
– Higher availability of the system – less maintenance
– Reduction of overall costs
