The sheet stack is placed inside the C, and the upper and lower jaws close on it.<\/p>\n<p>The frame then turns about the base axis, first through about 90 degrees, then on to about 180 degrees, carrying the stack with it. At the end the jaws open so the turned stack can be taken away. The operator stands back and runs the machine from a hand-held remote control; red and green buttons and lights are on the front of the base.<\/p>\n<h2 id=\"how-it-works\">How the stack is turned<\/h2>\n<p>Times are read from the video timestamps.<\/p>\n<table>\n<thead>\n<tr>\n<th>Step<\/th>\n<th>What happens<\/th>\n<th>Video time<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Clamp<\/td>\n<td>The stack is placed in the C and the jaws close<\/td>\n<td>about 0\u20138 s<\/td>\n<\/tr>\n<tr>\n<td>Turn to 90\u00b0<\/td>\n<td>The frame turns the stack on its side<\/td>\n<td>about 12\u201320 s<\/td>\n<\/tr>\n<tr>\n<td>Turn to 180\u00b0<\/td>\n<td>The frame carries on to turn the stack over<\/td>\n<td>about 24\u201344 s<\/td>\n<\/tr>\n<tr>\n<td>Release<\/td>\n<td>The jaws open for unloading<\/td>\n<td>about 48\u201356 s<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Stopping at 90\u00b0 stands the stack on edge; going on to 180\u00b0 turns it fully over.<\/p>\n<h2 id=\"weight\">Stack weight from the sheets<\/h2>\n<p>Illustrative example:<\/p>\n<table>\n<thead>\n<tr>\n<th>Item<\/th>\n<th>Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Sheet size (illustrative)<\/td>\n<td>1,250 \u00d7 2,500 mm<\/td>\n<\/tr>\n<tr>\n<td>Sheet thickness (illustrative)<\/td>\n<td>2 mm<\/td>\n<\/tr>\n<tr>\n<td>Sheets in the stack (illustrative)<\/td>\n<td>50<\/td>\n<\/tr>\n<tr>\n<td>Steel volume, 1.25 \u00d7 2.5 \u00d7 0.002 \u00d7 50<\/td>\n<td>about 0.313 m\u00b3<\/td>\n<\/tr>\n<tr>\n<td>Weight at 7,850 kg\/m\u00b3<\/td>\n<td>about 2,450 kg<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Add the pallet weight to get the load the clamp has to turn.<\/p>\n<h2 id=\"safety\">Controls and safety<\/h2>\n<p>The clamp frame turns a full stack through up to 180 degrees.
