Gstruck Glass Transport Truck
A shop-to-site glass sheet transport checklist covering rack arrangement, edge support, and strap tension so sheets arrive intact.
Large glass sheets rarely crack because of the road. They crack because the load shifted before the truck left the yard: a missing wedge in the A-rack, a strap tensioned against a bare edge, a bay that was filled before the previous bay was locked. Once vibration takes over, the sheet that was fine at the bench arrives as scrap and the delivery window is gone with it.
A purpose-built Gstruck glass transport truck body splits the load into supported bays, matches rack angle and strap points to sheet size, and keeps every sheet edge-protected and tensioned from the workshop door to the loading bay. This checklist is the short list of what a glazing crew should walk through before the first sheet leaves the rack.
Split the Load into Supported Bays Before Loading
Start by reading the load sheet the same way you read a lifting diagram: total sheet weight, sheet dimensions, and the order they come off the rack. A Gstruck truck body is built around A-frame racks and padded clamping matched to sheet sizes, so each bay should be planned as a self-contained stack with its own edge support and its own strap points. Do not stack mixed sizes in one bay; mixed sizes share an edge line and that is where the first crack always shows up. Walk the empty bay first. Confirm the padded clamps are seated, the strap points line up with the sheet size you are about to load, and that the bay floor is clean. A clean bay floor is the difference between a sheet that slides under braking and a sheet that stays put.
Match Strap Points to Sheet Size and Edge Type
Strap points on a Gstruck body are positioned to spread load across the supported bay, not to pull a sheet flat against the rack. Before you tension, check three things: the strap is rated for the sheet weight in that bay; the strap path crosses a padded clamp or the A-frame beam, never a bare edge; and the ratchet is free to take up tension without twisting the strap. Tension in stages, not in one pull. A first pass takes the slack out, a second pass evens the stack, and the final pass is the one you read on the gauge. A strap that is tight on one bay and loose on the next is a strap that has not done its job.
Lock the Edge Before the Sheet Leaves the Rack
Edge support is the single point most crews skip because the sheet looks stable on the bench. On the road it is not. A Gstruck A-frame rack is built so the sheet rides edge-supported through the whole bay, with padding taking the contact instead of the glass. Confirm that the lower edge sits fully into the padded support, the upper edge is captured by the clamp, and there is no daylight between the sheet and the rack. If daylight is visible, the sheet is being carried by the strap, not by the rack. A sheet carried by the strap under braking will crack long before it reaches the site.
Walk the Load One More Time Before the Tarp Goes On
The last check before the tarp or curtain goes on is the one that catches the rest. Stand at each bay and look at the strap, the clamp, and the edge. Pull each strap sideways to confirm it has not walked up the stack. Look down the bay line to confirm every sheet is riding edge-supported. Tap the rack padding to confirm it has not shifted during loading. This walk takes two minutes and it is the cheapest insurance on the truck. Once the tarp is on and the truck is moving, the only way to find a problem is to hear it.
Read the Working Envelope the Same Way You Read It on Site
The same envelope rule that governs a Gstruck glass robot on site applies to the truck body on the road: load capacity is rated at a defined geometry, and it falls off as the geometry changes. A bay that is filled past its rated sheet size, a strap path that pulls outside the rack line, or a stack that leans out of the A-frame all reduce the real capacity of that bay, the same way extending a boom reduces the lift rating. Keep each bay inside its rated sheet size, keep the strap path inside the rack line, and keep the stack square to the rack. Outside that envelope, the bay is the weakest link in the chain from shop to site.
Pre-Departure Checklist for the Glazing Crew
- Confirm each bay is planned as a self-contained stack matched to sheet size; do not mix sizes in one bay.
- Confirm padded clamps are seated and the bay floor is clean before the first sheet goes in.
- Confirm strap is rated for the bay weight, crosses a padded clamp or beam, and ratchets without twist.
- Tension straps in stages: slack out, even the stack, then read the final tension on the gauge.
- Confirm lower edge sits fully in the padded support and the upper edge is captured by the clamp.
- Confirm no daylight between sheet and rack; the sheet must ride edge-supported, not strap-supported.
- Walk each bay one last time: strap, clamp, edge, padding, rack line, stack square.
- Confirm each bay is inside its rated sheet size and the strap path stays inside the rack line.
