It clamps a pallet load between them, a hydraulic cylinder tilts it 90\u00b0, and the operator can turn it 180\u00b0 to invert it. It handles 100 to 1,000 kg with up to 1,200 mm between the forks.

Sheet stacks arrive on one pallet type and must go onto another, or be turned so the bottom sheet can be inspected. A crane and chains can do it, but every turn needs a slinger and a free crane.<\/p>\n<p>A mobile inverter brings the turning to the load. It drives to the pallet, clamps it, turns it and drives it to the next workstation, with no crane and no fixed station.<\/p>\n<h2 id=\"how\">How the double-fork inverter works<\/h2>\n<ol>\n<li>The operator drives the inverter to the pallet; the travel drive moves it forwards and backwards.<\/li>\n<li>The bottom forks go under the pallet, and one button brings the top forks down onto the load, clamping it between them.<\/li>\n<li>A hydraulic cylinder raises the clamped load through 90\u00b0, from upright to on its side.<\/li>\n<li>For a full inversion, the operator turns the load through 180\u00b0 by hand on the rotating head, then returns it smoothly to the start position.<\/li>\n<li>The machine carries the turned load to the next station, or sets it down on a new pallet.<\/li>\n<\/ol>\n<p>The forks hold the load with a constant press force, so loose items between them do not slip out while the load is on its side.<\/p>\n<p>Two points matter for steel. First, set an off-centre mold so its centre of gravity sits as close as possible to the turning axis; an offset mass adds a tipping moment while the head is turned by hand. Second, the hydraulic pressure is not the pressure on the load face, which depends on the contact area. On thin sheet edges or finished mold faces, a flat plate or timber under the top forks spreads the force.<\/p>\n<h2 id=\"specs\">Mobile inverter specifications<\/h2>\n<table>\n<thead>\n<tr>\n<th>Item<\/th>\n<th>Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Load<\/td>\n<td>100 to 1,000 kg<\/td>\n<\/tr>\n<tr>\n<td>Fork width \/ length<\/td>\n<td>150 \/ 880 mm<\/td>\n<\/tr>\n<tr>\n<td>Fork spacing<\/td>\n<td>560 mm<\/td>\n<\/tr>\n<tr>\n<td>Maximum gap between top and bottom forks<\/td>\n<td>1,200 mm<\/td>\n<\/tr>\n<tr>\n<td>Tilt<\/td>\n<td>90\u00b0, hydraulic<\/td>\n<\/tr>\n<tr>\n<td>Rotation<\/td>\n<td>180\u00b0, manual<\/td>\n<\/tr>\n<tr>\n<td>Travel speed<\/td>\n<td>4.5 \/ 6.0 km\/h<\/td>\n<\/tr>\n<tr>\n<td>Hydraulic station<\/td>\n<td>DC 24 V, 2 kW<\/td>\n<\/tr>\n<tr>\n<td>Drive<\/td>\n<td>DC 24 V, 1.2 kW<\/td>\n<\/tr>\n<tr>\n<td>Battery<\/td>\n<td>12 \u00d7 2 V, 280 Ah<\/td>\n<\/tr>\n<tr>\n<td>Charger<\/td>\n<td>24 V \/ 40 A, with gauge<\/td>\n<\/tr>\n<tr>\n<td>Machine weight<\/td>\n<td>750 kg<\/td>\n<\/tr>\n<tr>\n<td>Safety<\/td>\n<td>red mushroom E-stop; emergency battery disconnect<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2 id=\"example\">Worked example: how much steel fits under 1,000 kg<\/h2>\n<p>Steel weighs about 7,850 kg\/m\u00b3, so a steel load reaches the 1,000 kg limit long before it fills the 1,200 mm fork gap.
