The frame hangs in chains from both ends of a beam on an overhead runway. The method relies on the frame being one rigid body: nothing inside it can shift as the angle changes. That is why it suits welded frames, girders and machine beds \u2014 and why it cannot be applied safely to sheet packages or plate bundles.<\/p>\n<h2 id=\"why-not-chains\">Why sheet stacks need clamping, not slings<\/h2>\n<p>A welded frame is one rigid body. Chains can roll it, because nothing inside the frame can move.<\/p>\n<p>A stack of steel sheets is different:<\/p>\n<ul>\n<li><strong>The sheets can slide on each other.<\/strong> In a sling, the stack can fan out as it passes vertical.<\/li>\n<li><strong>Thin sheets bend<\/strong> where a chain bears on them, and the edge marks stay.<\/li>\n<li><strong>Coated or polished sheets scratch<\/strong> where they rub on chain links.<\/li>\n<\/ul>\n<p>So for sheets and plate stacks, the load must be clamped as one block for the whole turn. That is what a C-type upender does.<\/p>\n<h2 id=\"c-type\">Our equivalent solution: the C-type steel sheet upender<\/h2>\n<p>Our steel sheet upender is a C-type frame on the floor. The stack is driven or placed into the C, hydraulic cylinders clamp it, and a motor turns the C through 180\u00b0.<\/p>\n<p>Data from our steel sheet upender page:<\/p>\n<table>\n<thead>\n<tr>\n<th>Parameter<\/th>\n<th>Baseline Value<\/th>\n<th>Engineering Unit<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Max. load<\/td>\n<td>15 t<\/td>\n<td><\/td>\n<\/tr>\n<tr>\n<td>Load length<\/td>\n<td>100\u20133000 mm<\/td>\n<td><\/td>\n<\/tr>\n<tr>\n<td>Load width<\/td>\n<td>250\u20131850 mm<\/td>\n<td><\/td>\n<\/tr>\n<tr>\n<td>Load height<\/td>\n<td>10\u2013350 mm<\/td>\n<td><\/td>\n<\/tr>\n<tr>\n<td>Turning motor<\/td>\n<td>2.5 kW<\/td>\n<td><\/td>\n<\/tr>\n<tr>\n<td>Hydraulic system<\/td>\n<td>4.5 kW<\/td>\n<td><\/td>\n<\/tr>\n<tr>\n<td>Hydraulic cylinder<\/td>\n<td>OD 100 mm, double acting<\/td>\n<td><\/td>\n<\/tr>\n<tr>\n<td>Machine size<\/td>\n<td>approx.

The turning area is fenced or marked to suit the layout of each project.<\/p>\n<h2 id=\"engineering-faq\">Engineering FAQ<\/h2>\n<p>Q: What is the primary operational difference between a beam chain turner and a C-type upender?\nA: The chain turner rolls a rigid frame in slings hanging from a beam. The C-type upender clamps the load as one block and turns it on the floor, which is what sheets and plate stacks need.<\/p>\n<p>Q: What is the maximum load capacity of the baseline C-type steel sheet upender?\nA: It handles up to 15 t, with loads up to 3000 mm long, 1850 mm wide and 350 mm high.<\/p>\n<p>Q: How is the sheet stack secured against shifting during the 180\u00b0 rotation?\nA: By double-acting hydraulic cylinders, OD 100 mm, which clamp it inside the C-frame while the motor turns it.<\/p>\n<p>Q: Is the rotational speed adjustable?\nA: Yes. Turning speed is adjustable, so you can slow the turn through the vertical point.<\/p>\n<p>Q: What are the connected drive power requirements for this equipment?\nA: A 2.5 kW turning motor and a 4.5 kW hydraulic system for the clamp, on the listed model.<\/p>\n<p>Q: What floor space is required for the machine footprint?\nA: The listed machine is approx. L3000 \u00d7 W2200 \u00d7 H2600 mm.
