- the chamfered walls 32 of the slot 28 are arranged to face the structure 10.
- the backing 14 may be welded in place at the welding apertures or recesses 43, 49 within and alongside the backing 14.
- the retainer 22 is then inserted into the slot 28 via the entry portion 20 and is slid along the slot 28 such that the retainer 22 locates with the end of the slot 34.
- the liner 16 is then fitted atop the backing 14 with the locating portions 35, 37 that extend from the backside 39 of the liner 16 received by the locating cutouts 31, 33 of the backing 14.
- the fastener 20 is then fitted through the liner aperture 24 of the liner 16 so as to engage with the retainer 20 thereby securing the liner 16 with the backing 14.
- the cap 52 may be fitted to conceal the liner aperture 24 and the jacking aperture 54 may be concealed with the plug 54.
- the cap 52 and the plug 54 serves to inhibit material such as dirt entering the respective apertures 24, 54.
- the cap 52 and plugs 54 may be removed to reveal the fastener 20 and jacking aperture 54, respectively.
- the fastener 20 may be loosened and removed.
- the jacking aperture 54 is threaded so that if the liner 16 is stuck, the plug 54 can be removed and a suitable threaded bolt can be inserted into the jacking aperture 54 to "jack" the liner 16 from the backing 14.
- the liner 16 may then be rotated 180 degrees, removed or replaced.
- the retainer 22 may be slidably removed and replaced whilst the backing 14 remains welded to the structure 12.
- pluralities of the wear liner assembly 10 may be fitted adjacent one another and with adjacent liners 16 proximate one another.
- the backing 14 may be provided as a common backing to which pluralities of adjacent liners 16 liners are fitted.
- a wear liner assembly having a cast wear liner and a backing plate that are arranged to allow the wear liner to be easily replaced using a coupling arrangement. As such, welding is usually not required when changing the liners.
- the wear liner and backing plate are arranged to inter-fit with one another as well as securely and releasably couple with one another in the installed condition.
- the retainer that is slidably received by the backing is easily replaceable and therefore extends the life of the backing plate in the event that the retainer becomes damaged or worn.
- the other components of the coupling arrangement are also replaceable.
- the wear liner assembly may be used in most applications including structures such as bins, tubs, crushers, chutes, skips, and buckets.
- the coupling allows the liner to be removed directly away from the backing without lateral or vertical movement of the liner which allows adjacent wear liners to be fitted at relatively close spacing and the adjacently liners being able to be removed and fitted to the backing.
- the liner can be coupled to the backing in two opposing orientations thereby allowing the wear face to be rotated and gaining further life from the wear liner.
- the location portions of the liner and cutouts of the backing take shear stress loads subjected to the liner. Forces on the coupling arrangement thereby being reduced or minimised.
