What RELIANCE CONTROL LTD does

Reliance Control Limited (trading in part as Lifteknic) is a privately held UK-based company founded in 2012 that designs and supplies embedded elevator controllers and VVVF drive upgrade solutions for lift systems. The company's core product is the RCL Advanced Elevator Control Platform, a fully in-house designed embedded elevator controller built around a high-performance 32-bit ARM microcontroller with dual galvanically isolated CAN bus connections, 22 galvanically isolated inputs, and force-guided safety relays for directional switching. The platform supports traction and hydraulic systems and includes multi-car group operation, smartphone connectivity with full menu access, statistical call pattern recording, accelerometer-based maintenance data, absolute encoder positioning for fast floor setup, speech output, and USB firmware upgrades. The controllers comply with EN81-20 and EN81-50 elevator safety standards. Supporting product lines include the QUBE AC Gearless Controller, Quatrain Controller, and Comtek 80, plus a Cartop Control Board with absolute positioning.

The company also operates a drive upgrade and replacement service that migrates installed elevator systems from discontinued VVVF drives (Control Techniques Unidrive SP, Wittur WVD, Ziehl Abegg 2CF) to current-generation alternatives (Control Techniques E300, Fuji Frenic LM2), supported by documented integrations with drive suppliers including Control Techniques, Fuji Electric, Ziehl Abegg, and Wittur. Additional offerings include electronic component support, spare parts supply, and a custom embedded Design Service for customer-specific elevator control solutions. The business model is direct B2B sales to elevator/lift companies, qualified elevator technicians, and building management firms, with pricing on a quote basis and no publicly disclosed pricing. The company is registered in England & Wales (Company No. 08323226), operates from a single UK headquarters, and has no disclosed subsidiaries, funding rounds, management team, or named major customers.
