Introducing. Zafety Lug Lock Slide 2 Revolutionary new safety product Setting new standards in wheel management Helps prevent lug nut loosening Reduces risk of potential wheel loss Decreases the possibility of costly wheel damage Slide 3 Wheel nuts loosen as a result of temperature change and wheel vibration. Zafety Lug Lock Zafety Lug Lock creates resistance between 2 nuts minimizing their ability to rotate & loosen. Designed for use on all wheels with 1-5/16 inch (33mm) nuts on 3.5 inch stud centers. Easily installs over 2 adjacent nuts. Slide 4 Pre-trip inspection requires confirmation of secure wheel lug nuts Rules apply to all public transit & commercial buses, trucks, trailers Zafety Lug Lock Zafety Lug Lock provides a clear, visual check of lug nut position* Zafety Lug Lock * The installation of Zafety Lug Lock does not preclude the need for standard safety & maintenance procedures Slide 5 Fleet and Driver liability is a critical issue: NHTSA records show 1,000 reported accidents resulting from wheel loss in 2008. Many wheel loss incidents go unreported. $6.25 million civil award in a California personal injury accident from a wheel off. Slide 6 Benefits Provides a clear visual check of lug nut security Reduces risk of wheel loss and potential liability for personal injury, loss of life or property damage Reduces need for replacement lug nuts and reduces expensive wheel damage Economical to outfit commercial vehicles Reusable on replacement wheels Slide 7 Features Flexible and easy to install - fits over two adjacent nuts Field tested at high and low rotation levels Lab tested in severe vibration conditions from -40 0 F to +122 0 F (-40 0 C to +50 0 C) designed to be used on wheels with 1-5/16 inch (33mm) nuts on 3.5 inch stud centers available in custom colors Slide 8 Testing performed by Bodycote Testing Group Parameters: Zafety Lug Lock 1. Three Zafety Lug Lock units tested 2. Temperature testing at 25C (77F), 50C (122F) and - 40C (-40F) 3. Vibration test at 30 Hz and 3 g acceleration amplitude 4. Each segment of the test was two hours with a total duration of 6 hours Slide 9 TEST PROCEDURE: 4 nuts tightened to spec (450-500 psi) 2 nuts hand tightened White line applied to nuts and bolts to identify positioning Vibration at specific temperature for 2 hours Zafety Lug Lock Visual inspection of Zafety Lug Lock units and nuts for any changes Slide 10 TEST PROCEDURE: Figure 4A: Photos of Zafety Lug Lock prior to vibration test at 50 C 2 nuts hand tightened White line for alignment Slide 11 Observations Zafety Lug Lock After testing at each temperature level a visual inspection indicated the Zafety Lug Lock units did not sustain any external damages or physical degradation After testing at each temperature level a visual inspection indicated no evidence of any nut looseness Slide 12 LUG NUT POSITION AT 50C (122F) BEFORE VIBRATION TESTING LUG NUT POSITION AT 50C (122 F) AFTER VIBRATION TESTING Figure 4A: Photos of Zafety Lug Lock prior to vibration test at 50 C Figure 5A: Photos of Zafety Lug Lock after vibration test at 50 C No evidence of nut looseness Slide 13 Zafety Lug Lock Zafety Lug Lock will have a positive impact on your fleet: Reduced liability from risk of potential wheel loss. Lower maintenance costs from possible wheel damage and lug nut replacement. Simple visual check on wheel nut position Allows fleets to visibly demonstrate proactive safety measures Slide 14 Zafety Lug Lock For more information on Zafety Lug Lock : Spectra Products Inc.
