User manual GRADAV VERSATILE ROSTRA & STAGING SYSTEM

[. . . ] The ring on the stage leg should locate tight against the coupler on the deck. The legs struts where fitted should now be located onto the pins on the inside edges on the stage deck frame. It is important to locate the strut onto the pin nearest the stage frame middle bearer first. The wing nut on the coupler fitting can then be tightened by hand only (The use of tools to achieve greater leverage can result in damage to both the coupler and stage leg. ). Where stage levelling legs or generic adjustable stage legs are not being used ensure that a stage bung is fitted as a foot to the bottom of the leg. [. . . ] The inboard pin on the AUC locates into a hole in the underside of the stage frame, which correctly aligns the fitting. The wing nut on the coupler fitting should be tightened by hand only (The use of tools to achieve greater leverage can result in damage to both the coupler and stage leg. ). They can be orientated to allow either one or two arms of the fitting to extend beyond the edge of the stage deck. Adjacent stages can be lifted into position, allowing the pin at the end of the AUC arm to locate into the hole in the underside of the stage deck frame. Stage Guardrails These are made up of horizontal rails and vertical posts. The horizontal rails have a swaged spigot at both ends, which locate into the vertical posts. Once a run of guardrails have been assembled (rails to posts) the posts can then be fitted to the stage, with the swaged spigot at the bottom of the vertical post fitting through the holes in the plywood stage decking, locating into the top of the stage leg. To allow for various configurations of guardrail to be constructed horizontal rails are available in a range of standard sizes, with a number of different styles of post also available. It is possible to fit guardrails to the sides of tiered stages using step middle posts and tiered seating horizontal tubes, which are swaged at one end only. Steps Flights of steps are built from individual step treads and step legs rather than being pre-engineered flights. Step legs of 200mm are fitted with one ring whilst longer legs are fitted with two rings. Fit two 200mm step legs to the inboard couplers on the first tread ensuring that the rings on the legs locate tight against the couplers. Fit two 400mm legs to the outboard couplers on the same tread ensuring that the bottom rings on the legs fit tight to the underside of the coupler. Locate the next step tread onto the top of the 400mm step legs with the legs fitting into the inboard couplers with the top rings fitting tight to the couplers (see illustrations overleaf). The next size step legs can be fitted to the outboard couplers on the upper tread and the process of locating the next step is repeated until the final tread has been fitted. Once the final tread has been fitted, the completed step assembly can be located to the end of a 1. 22m wide stage and the outboard couplers on the top tread attaching to the stage legs. The wing nuts on the coupler fittings should be tightened by hand only (The use of tools to achieve greater leverage can result in damage to both the coupler and stage leg. ). Step Guardrail Guardrail can be fitted to either one or both sides of steps. Two types are currently available, "stepped" or "inclined". In both cases the swaged spigot at the bottom of the vertical post locates into the top of the step leg passing through the holes in the plywood step decking. The stepped guardrail requires three different types of post that spigot together prior to fitting to the steps. The bottom step uses a stage end post, the top step uses a step top post with the intermediate steps using middle posts. The inclined guardrail only uses only one type of post throughout. Posts are joined together using expanding spigots, which are operated with a hexagonal (Allen) key. The posts should be assembled loosely, and then fitted to the steps prior to the expanding spigots being tightened. Where step guardrail is not being used the holes in the step are in-filled with 6mm bungs. Valance Small pads (25mm) of self adhesive hook "male" Velcro should be affixed to the top edge of the stages to where the valance is to be attached (approximately one pad every 300mm). The valance, which has loop "female" Velcro stitched to its top edge, can now be attached. [. . . ] The customer will remain liable for the full cost of the hire and carriage. Extra charges may be levied for a second delivery attempt and/or the cost of providing assistance to the driver. 28 Where a collection with staging has been arranged it is part of the contract that there is at least 1 person capable of assisting the driver to carry decking panels for the purposes of loading. Failure to provide this assistance may result in the non-collection of the goods. [. . . ]
