GLASS RACK LOAD CAPACITY | MODEL-SPECIFIC SELECTION
A single “2-ton” number can mislead a glass-rack buyer. Grack capacity, dimensions, handling interfaces, and container loading must be checked by opportunity and model—not copied across an entire L-frame rack range.
When an engineer searches for glass rack load capacity or an L-frame rack 2000kg, the quickest answer is often the wrong one: “This glass rack is rated at 2 tonnes.” That statement may describe one reinforced configuration, but it does not describe every Grack. A 750 kg rack, an 800 kg rack, a 1,000 kg rack, a 2,000 kg rack, and a 2,500 kg rack are different load-bearing packages. Their footprint, tube arrangement, base, reinforcement, self-weight, and packing plan can also differ.
For purchasing, production engineering, and logistics, the safe rule is simple: match the opportunity number, drawing, rated load, glass format, handling method, and shipping plan as one set. Do not use one model’s capacity or container count to approve another model. The rating is a selection input, not a generic marketing label.
Verified Grack capacities: read the model, not the headline
The verified snapshots show why a single load number is incomplete. Opportunity 10777 is a 1200 × 900 × 1200 mm rack rated for 750 kg, with approximately 46 kg self-weight. Opportunity 10895 is 1180 × 600 × 1155 mm and rated for 800 kg, with approximately 47 kg self-weight. Opportunity 15742 is a longer 2400 × 750 × 1200 mm rack rated for 1,000 kg and approximately 112 kg self-weight, intended for 4 × 8 ft panels. Opportunity 14792 is 2000 × 1300 × 1300 mm and rated for 2,000 kg; its documented weight is 81 ± 3 kg without rubber or 93 ± 5 kg with rubber. Opportunity 15725 is rated for 2,500 kg: the single-side version is 1800 × 950 × 1600 mm and approximately 80 kg, while the double-side version is 1800 × 1150 × 1620 mm and approximately 168 kg. The 05205 Canada configuration is 1600 × 950 × 1600 mm and limited to not more than 2 tonnes, with reinforced joints, a raised angle, a fully welded forklift entrance, and mechanically screwed steel-plate rubber fixing. These are not interchangeable specifications. They are model-specific evidence.
Why capacity cannot be unified across L-frame glass racks
Capacity depends on more than the steel grade. Grack uses Q235 carbon steel, full-seam welding at key load-bearing joints, and project-specific tube or channel combinations such as 50 × 50 square tube, 50 × 25 rectangular tube or C-channel, and heavier 100 × 50 or 180 × 80 base channels. The load path changes with rack length, base depth, glass centre of gravity, support spacing, and reinforcement. A 2,500 kg double-side frame also has a different self-weight and working geometry from a 2,500 kg single-side frame. A 2,000 kg rack may suit one glass format but be unsuitable for another if the panel overhang, height, or handling route changes. The 05205 limit of not more than 2 tonnes must remain attached to that configuration; it cannot be transferred to 14792 or any other opportunity. Rated capacity also does not automatically mean safe use on an uneven floor, with unverified forks, or with a different restraint method. Confirm the complete load case before release.
Container loading is a geometry calculation
Shipping quantity must be calculated after the exact model and nesting method are fixed. The documented figures are different: 10777 loads about 100 units on a 9.6 m flatbed; 10895 records 250 units in a 40HQ for its project file; 14792 records 33 units in a 20GP and 78 units in a 40HQ; 15725 single-side records 24 units in a 20GP and 84 units in a 40HQ. No verified universal cabinet count is assigned here to 15742 or 05205, so those quantities must be worked out from their actual dimensions, stack orientation, protective clearances, and transport restrictions. The 15725 double-side variant has a different 1800 × 1150 × 1620 mm envelope and approximately 168 kg self-weight; its single-side loading counts must not be reused. Nesting can sharply reduce empty return volume, but the number of racks per truck or container is never a substitute for a model drawing and packing plan.
Selection checks that keep the rating and logistics plan aligned
- Identify the exact opportunity and configuration. Record the model number, single-side or double-side layout, dimensions, rated capacity, self-weight, glass size, and centre-of-gravity assumptions together. Never mix 10777, 10895, 14792, 15725, 15742, and 05205 data.
- Calculate loading from the physical envelope. Use the documented count only for its matching model: 100 on a 9.6 m flatbed for 10777, 250 in a 40HQ for 10895, 33/78 in 20GP/40HQ for 14792, and 24/84 in 20GP/40HQ for 15725 single-side. Request a separate packing calculation where no verified count is available.
- Choose handling options around the real route. Forklift pockets, pallet-jack clearance, lifting pins, tie-down points, retaining bars, and casters are project variables. Add casters when frequent short-distance movement and floor conditions justify them; keep the rated load, wheel capacity, brakes, and handling SOP matched to the selected model.
- Specify corrosion protection by exposure. Powder coating is the common finish in the indexed Grack configurations. For persistent outdoor moisture or corrosive service, ask whether hot-dip galvanizing is appropriate and confirm the coating, weld, drainage, tolerance, and rubber-interface details for that exact design. Do not assume galvanizing changes the load rating or makes models interchangeable.
