    SanJuan EZ TRUSS

    ASTM F432 gr6 -Nominal 30 Ton Capacity

    TheDYWIDAGSanJuanEZTrusscombineseaseof installation with superior support performance. Itcanbeinstalledsafelyfromthebolterwithoutexposure to unsupported roof at anytime.

    InstallationThe truss shoe and the inclined bolt can be installedfirstandseparatelyfromthetruss.Apiece of 0.6" cable is inserted into the end of truss shoe automatically engaging the cable grip wedges. This can be done without leaving the protection of the bolter. Then both cables are fed through the cable truss coupler in the middle. Wedges are installed into barrels against the cable truss coupler and stressing may commence using a hydraulic tensioning unit. The truss shoeisdesignedtoaccommodate#7or#8barand angles between 45 and 60 degrees to the horizontal.

    UsesCable slings can be used as primary ground support in drifts, for the construction of sill mats and for wrapping pillars. Cable slings are particularly useful in soft, yielding ground or in areas prone to rockbursts.

    MaterialsEach sling is comprised of a length of cable (see chart below) with drive blocks or buttons, 2 pc. of 5' (1.5m) 39mm friction stabilizers and a minimum of 6 cement cartridges (32mm diameter), three per hole. Cables can be either 0.5" (12.7 mm) or 0.6" (15.2 mm).

    Cable Slings

    Cable Length and Spacing

    InstallationHoles are always drilled 8' (2.4m) in length and are generally oriented at approximately 45 degrees. Three cement cartridges are immersed in water, andwhenready,insertedintothefirstholeandtampedtotheend.Oneendofthecableistheninserted manually into the hole. The cable is slid into the gap in the end of the friction stabilizer and the bolt is fully installed. The same process is repeated for the other end of the cable.

    Ifproperlyinstalledthefrictionstabilizerswillholdapproximately 1 ton per foot of length and will immediately tension the cable. Blocks or wedges can be inserted between the cable strand and the rock. After the cement cures the full strength of the cable can be mobilized.
