Turning the whole stack keeps the sheets aligned and protects the surface.<\/p>\n<p>Lifting and turning a heavy stack by crane or by hand risks dropping the load. A cradle turn is safer and repeatable. Stack range is confirmed per project.<\/p>\n<h2 id=\"what-the-machine-does-3809\">What the machine does<\/h2>\n<p>The machine is a steel sheet inverter and turning machine. A clamping cradle holds the stack, and the cradle turns around a horizontal axis on the base so the sheets rotate together. The stack passes through a controlled arc and returns to the resting position at the end of the turn.<\/p>\n<p>The operator starts the turn and the machine does the movement. Cradle size and turn angle are confirmed per project.<\/p>\n<h2 id=\"cradle-and-clamp\">Cradle and clamp<\/h2>\n<p>The stack sits in a clamping cradle with parallel plate supports that hold the sheets in place. Once closed, the cradle carries the stack as a single unit.<\/p>\n<p>Holding the stack in the cradle stops the sheets separating during the turn. Clamp range is confirmed per project.<\/p>\n<h2 id=\"turn-through-the-arc\">Turn through the arc<\/h2>\n<p>The footage shows the cradle rotating from its resting position and back, so the stack turns through the arc in each direction. Because the turn is mechanical, the stack arrives at the same position every cycle.<\/p>\n<p>A controlled arc keeps the load over the cradle at all times. Turn speed and stop position are confirmed per project.<\/p>\n<h2 id=\"what-the-footage-shows\">What the footage shows<\/h2>\n<p>Our footage shows a stack held in the clamping cradle, the cradle turning away from its resting position and back under power. It is a general demonstration, so your stack size, weight and turn angle are confirmed with us per project.<\/p>\n<h2 id=\"typical-configuration\">Typical configuration<\/h2>\n<p>Figures below list functional design boundaries rather than numeric values, and are confirmed per project.<\/p>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Parameter<\/th>\n<th style=\"text-align: left\">Typical range, confirmed per project<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Load<\/td>\n<td style=\"text-align: left\">steel sheet stack<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Hold<\/td>\n<td style=\"text-align: left\">clamping cradle<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Turn<\/td>\n<td style=\"text-align: left\">horizontal axis arc<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Control<\/td>\n<td style=\"text-align: left\">start and stop from panel<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Mount<\/td>\n<td style=\"text-align: left\">floor base<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Electrical supply<\/td>\n<td style=\"text-align: left\">380 V three phase 50 Hz, or 220 V single phase for light machines, selected per project<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"selection-checklist\">Selection checklist<\/h2>\n<table>\n<thead>\n<tr>\n<th style=\"text-align: left\">Question<\/th>\n<th style=\"text-align: left\">Confirm per project<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"text-align: left\">Load range<\/td>\n<td style=\"text-align: left\">stack size, weight, sheet count<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Cradle<\/td>\n<td style=\"text-align: left\">clamp opening, plate size<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Turn<\/td>\n<td style=\"text-align: left\">angle, direction<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Access<\/td>\n<td style=\"text-align: left\">forklift or crane loading<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Cycle<\/td>\n<td style=\"text-align: left\">turns per shift<\/td>\n<\/tr>\n<tr>\n<td style=\"text-align: left\">Electrical supply<\/td>\n<td style=\"text-align: left\">voltage, phase and frequency on site<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"operation-and-safety\">Operation and safety<\/h2>\n<p>Load the stack into the open cradle, then start the turn from the control panel.
