Once again as in 2009 and before Lika Electronic will exhibit at the 10th Interlift 2011 international trade fair for elevators (http://www.interlift.de/en/home.html). Interlift takes place in Augsburg, Germany from October 18 to 21, 2011. During the years Interlift has become the worldwide leading trade fair for the elevator industry with around 500 exhibitors and an exhibition area of over 40,000 m². Lika's stand is located in Hall 3, Booth 3104. With more than 15 years of extensive experience worldwide in the elevator industry, Lika Electronic can boast a comprehensive range of both incremental and absolute, rotary and linear encoders for installation on elevators, escalators and moving walks. The fair will provide a great opportunity to showcase Lika's latest innovative and market-leading products dedicated to tackling any critical tasks in the elevator industry.
Geared and revolutionary gearless traction motors require rugged, vibration-resistant, high-accuracy and precision and long service life encoders for improving the car comfort and reducing the maintenance costs, at the highest safety levels. To meet the more and more rising demands of such an application, to all intents and purposes the core of the elevator system, Lika Electronic offers solid and hollow shaft encoders in both incremental and absolute versions providing a wide range of mechanical and electrical interfaces suited to any drive machine and controller. For geared traction motors C82 model has been introduced in the market recently. C82 is a hollow shaft incremental encoder with increased shaft loading values (up to 200 N) and extended operating temperature range (-40°C +100°C). Together with C80 & C81 models it can be installed directly in the motor shaft saving space and requiring no mechanical adjustments. Gearless traction motor technology has brought about rapid changes within the elevator industry. Encoders for gearless motors are sturdy, reliable, accurate; furthermore, especially in MRL installations, they must be really compact. They feature both incremental signals for speed feedback and an absolute signal to detect the position of the motor poles. CB59 and CB60 incremental encoders with sine-cosine output and additional absolute track are available in both hollow and solid shaft versions. When an elevator drive requires digital pulses and UVW encoder signals, IB59 model is the most compact solution currently available on the market. Absolute encoders of the HS and HSC series have improved interfaces such as SSI + sin/cos and the fully digital BiSS. Resolutions up to 18 bits (262144 counts per rev) allow very accurate detection of the rotor/stator position.
Nowadays an overspeed governor and an incremental or absolute encoder for simple and reliable shaft copy are a safety system absolutely necessary for any elevator installation. HMCT absolute through hollow shaft encoder is among the market leaders and the most versatile product suitable for this application: it offers proven reliability and rugged quality, resolution up to 16 + 12 bits, reinforced IP-rated environmental protection, several output interfaces such as SSI and BISS as well as cables and plug connectors to suit the most common drives. For outstanding dependability and absolute safety Lika Electronic offers now the SGSM / SGSD incremental magnetic sensors. The SGSM / SGSD non-contact operation and the advanced magnetic technology ensure a steady and reliable functioning even in critical conditions. These encoders are virtually wear & maintenance-free, highly immune to dirt, finest dust particles, oil and grease and are also available in redundant version encompassing two separate sensors in the same still compact housing and independent circuitries. DRAW-WIRE units can be easily installed to measure car or platform positions on freight lifts, mobile platforms, scissor lifts and hoists and cranes as well. Small ranges up to 6,8 metres (267.7”) can be covered with the SF-I series while SAK and SBK are suitable for ranges up to 50 metres (1968.5”). Both series are available with seawater-proof housing surface protection, while SAK and SBK series can be supplied also in ATEX version.
Apart from being an unavoidable safety need, perfect precision of levelling at landings is also a specific requirement of recent lift directives. Lika Electronic offers simple, robust and affordable solutions, unaffected by environment conditions, non-contacting and therefore wear-free, capable of resolutions up to 0,1 mm (0.0039”). They allow for a balanced motion profile and high levelling accuracy in the most different load conditions. The SMAL series of linear magnetic measurement systems has been designed for demanding elevator car positioning applications. With a measuring range up to 500 metres (19,685”) and a resolution of 0,1 mm (0.0039”), the SMAL series is suitable not only for new installations but also for modernizing existing elevators. The complete system consists of two components only, a sensor and a magnetic tape available in both incremental and absolute coding. A fixing kit is supplied to mount the tape directly on the guides of the elevator car, in a simple and affordable way. The measuring principle is contactless. The tape is guided by the sensor casing in order to keep it always aligned with the sensor. The SMAL can be supplied with several interfaces such as CANopen (DS406), CANlift (DS417), SSI and RS485 for direct connection to all common elevator controllers.
For reliable 24-hour operation, car doors, heavy-duty escalators and moving walks need compact and rugged encoders, capable of unlimited enduring service, accurate and dependable at any time. Specific car door and escalator encoders have been developed by Lika Electronic to meet these requirements of a high number of cycles and continuous duty. The C50 series is a long-lasting solution for reliable 24-hour operation of both car doors and elevators, suitable also for installations in critical environments like off-shore or tropical climate. I70 is the newest compact solution for high performance door position from Lika Electronic: I70 is a harsh duty incremental encoder with optical sensing fully integrated into the compact and robust assembly of a pulley and thus it can be driven directly by a timing belt. The exceptionally robust construction makes it ideal for use in harsh environments and allows to tension the belt reaching shaft loads up to 1000 N (or 100 kg).
All Lika Electronic encoders only fit selected high-quality components and are inspected individually before delivery ensuring they can operate safely and reliably throughout the lifetime of the lift.
