Its robust cast-steel frame and high-inertia eccentric shaft deliver consistent throughput under continuous duty.<\/p>\n<p>The crushing chamber is formed by two opposing wear surfaces \u2014 the <em>fixed jaw<\/em> (stationary) and the <em>swing jaw<\/em> (reciprocating). Material is compressed and fractured between them on every stroke. Surrounding these liners, a set of supporting and clamping components keeps the wear parts seated, aligned, and tensioned so the crusher runs safely at full capacity. The seven parts listed below cover the complete wear and structural interface set for the CT4254 jaw module:<\/p>\n<ul>\n<li><strong>Fixed Jaw &amp; Swing Jaw<\/strong> \u2013 the primary crushing surfaces (manganese liners).<\/li>\n<li><strong>Wedge Die, Swing (LH\/RH)<\/strong> \u2013 clamps and locks the swing jaw liner to the swing jaw body.<\/li>\n<li><strong>Upper \/ Lower Cheek Plates (RH\/LH)<\/strong> \u2013 side liners that protect the crusher frame from abrasion.<\/li>\n<li><strong>Wedge Block (TRIO17003948)<\/strong> \u2013 the hold-down \/ tension component that maintains liner position and crushing gap.<\/li>\n<\/ul>\n<h2>Available Parts List<\/h2>\n<table class=\"parts-table\">\n<thead>\n<tr>\n<th style=\"width: 6%\">No.<\/th>\n<th style=\"width: 24%\">Part Name<\/th>\n<th style=\"width: 20%\">Part Number<\/th>\n<th style=\"width: 10%\">Model<\/th>\n<th style=\"width: 28%\">Function<\/th>\n<th style=\"width: 12%\">Weight (kg)<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>1<\/td>\n<td>Swing Jaw Plate<\/td>\n<td>TRIO17052179<\/td>\n<td>CT4254<\/td>\n<td>Movable crushing surface mounted on the swing jaw; the high-impact wear liner that does most of the comminution work.<\/td>\n<td>2,857<\/td>\n<\/tr>\n<tr>\n<td>2<\/td>\n<td>Fixed Jaw Plate<\/td>\n<td>TRIO17052178<\/td>\n<td>CT4254<\/td>\n<td>Stationary crushing surface; the fixed wear liner against which rock is compressed and fractured.
