7 Peterkin Street, Wingate, Lower Hutt PO Box 38055, Wellington Mail Centre 5045 0800 500 147 info@vanguardgroup.co.nz vanguardgroup.co.nz Operators Guide Introduction: Road Plate is a heavy duty modular trench cover system. Modules are made from fibreglass with steel reinforcing struts. Individual units link together. They can be installed with a two-person lift each section is just 42kg. Road Plate is viewed as a safer alternative to steel plates for trenches up to a maximum of 700mm wide. It has a weight bearing limit of 44 tonnes over a 700mm wide trench. Each section is 1500mm x 500mm. Only the end sections need bolting to the ground. Drop pin feature ensures lateral stability. Watch intro video here: https://vanguardgroup.wistia.com/medias/5wwspqdifs Vanguard Road Plate consists of two types of modules: Centre Modules (ramped) - 1500mm(L) x 500mm(W) End Caps (rounded) - 1500mm(L) x 500mm(W) Usability: The Vanguard Road Plate has been independently tested and certified to withstand a load of 44 tonnes spanning a 700mm trench, with a safety factor of 2:1. In addition, Oxford Plastics (manufacturer) performs regular batch tests to ensure the strength and quality of the products being manufactured. The Road Plates could be used up to a maximum speed of 65kmph safely, without causing any damage to vehicles, pedestrians or the product itself, however it is strongly recommended by Oxford Plastics and Vanguard that the posted speed must be 30kmph to ensure the most satisfactory performance. 30kmph must be the posted speed when the modular Road Plates are used in New Zealand as contractors will also need to display 'Uneven Surface' signs which immediately requires a 30kmph speed limit. As per the traffic plans drawn up by NZTA for the use of Road Plates, Oxford Plastics and Vanguard strongly advise that 30kmph be the advised speed limit under CoPTTM use.

Watch installation video here if this is the first time you are installing Road Plate: https://vanguardgroup.wistia.com/medias/enl9ejak9u 2. Visually check each unit prior to use. Do NOT use if damage is identifiable such as below: 3. Check the trench width does not exceed 700mm and sides of trench are secure 4. Check the drop pins are in working order 5. Lay out work site and signage according to NZTA site diagram (ref page 5) 6. Place Road Plates centrally over the trench. Plates join together with inbuilt steel linking pins. (see detail on page 7) 7. Once all the Centre plates are in place, link the End plates 8. Bolt End Plates to the ground with a minimum of 2 bolts (see recommended fasteners on page 4).

Further information on Road Plate Road Plate is a lightweight and long lasting alternative to steel. Road Plate is a heavy duty modular system for covering trenches to allow passage by traffic or pedestrians at road works. Made from lightweight GRP material with a steel lattice frame this system can be easily lifted by two people and manually installed in minutes - no cranes needed. Rated at 44T over a 700mm wide trench Weighing just 42kg and having been tested to a vehicle weight of 44 tonnes over a trench width of 700mm, they are often viewed as a safer alternative to traditional steel plates. The innovative flexible edge dampens any unwanted sounds making Road Plate ideal in residential areas, and the hi-visibility anti-slip surface improves safety for motorists and pedestrian safety for motorists and pedestrians on site. Road Plate is the ideal substitution to the steel plate, improving safety, decreasing installation time and traffic management costs and giving more flexibility and security to your site. Tested to a vehicle weight of 44 tonnes over a 700mm trench Can be installed in minutes Each section weighs just 42 kg - easy two person lift Can be transported in the back of a ute - no need for expensive specialist lifting equipment Ramp design helps slow traffic down for added safety Integral flexible ramped edge made from a PVC compound acts as a noise dampener when vehicles drive over them - ideal for residential areas Moulded anti-slip hi-vis yellow surface for traction Low profile end caps and non-slip surface eliminate trip and slip hazards for pedestrians Heavy duty steel links enable the modules to lock together securely and create a range of sizes Drop pin feature increases lateral stability Long lasting product, replacement parts available Designed and manufactured in UK Safer and more cost effective installation than steel plates Flexible ramped edge for noise dampening Moulded anti-slip and hi-vis modules for visibility and safety Compact storage and easy to transport LOCKING MECHANISM PREVENTS PLATES COMING APART OR MOVING SIDEWAYS LOCKING MECHANISM LOCKS EACH PLATE TO THE NEXT PREVENTING UPWARD MOVEMENT OF ANY PLATE DROP PINS PREVENT PLATES MOVING FORWARDS OR BACKWARD Ramp profile slows vehicles in work zones
