This Listing is for a NEW Wittur TKE OL35-NA Left Overspeed Governor. Wittur OL35-NA Overspeed Governor (Left-Hand Configuration) Specifications The Wittur OL35-NA is an ASME A17.1-compliant overspeed governor designed for elevator systems, providing bi-directional electrical disconnect and mechanical release for safety gear engagement in the down direction upon overspeed detection. It features a flyweight mechanism for overspeed detection and a pre-adjusted brake to limit force, protecting rope synchronization. The "left" likely refers to the left-hand orientation (mounting or pulley rotation direction), common in elevator governors for site-specific installations; standard specs apply unless customized (no unique left-hand variances found in documentation). The related OL35E-NA variant offers enhanced features like optional remote trip/reset and friction encoder. General Overview Product Type: Overspeed governor with unidirectional safety gear engagement (down direction primary). Function: Detects overspeed via flyweight mechanism; engages safety gear on full 360 pulley circumference; operates overspeed contacts in up and down directions. Key Features: Short response time (tripping at any perimeter point). Friction coupler to prevent rope damage. Hardened pulley for reduced wear. Safety covers included. Optional: Remote trip/reset device, friction encoder. Compliance: ASME A17.1, EN 81-20/50:2014, GOST R 53780-2010, China GB 7588-2003. Installation Location: Machine room or hoistway (floor-mounted).
