Technical assignment: Foldable wall-mounted barbecue grill for 10 skewers
Purpose:
Manufacture a durable foldable wall-mounted barbecue grill that can be folded and locked after grilling. It is installed near the garage on the wall. It must be safe, easy to use, and protected against theft.
⸻
1. Main dimensions and parameters:
• Grill length: 700 mm (fits 10 skewers with ~65 mm intervals)
• Grill depth: 350 mm
• Side wall height: 200 mm
• Steel thickness: 3–4 mm (preferably heat-resistant)
• Shape: rectangular box, folds downward
⸻
2. Construction:
• Grill pan: monolithic, welded, capable of withstanding high temperatures.
• Ash tray: sliding tray at the bottom for easy removal of ash.
• Frame: made of 30×30×2 mm profile pipe, mounted to the wall with anchor bolts.
• Hinges: reinforced, concealed (to prevent easy removal).
• Legs/supports: foldable or chains with a limiter, capable of supporting the weight of the structure.
• Fixation: in folded position, the grill lifts upward and is secured with a reinforced lock.
• Lock holes: welded, covered, recessed for vandal-proof protection.

3. Fittings and fasteners:
• Anchor bolts M10–M12 — 4 pcs
• Reinforced door/hinges — 2–3 pcs
• Foldable legs (steel Ø16 mm or profile 20×20 mm) — 2 pcs
• Stainless steel chains or cables with carabiners — 500 mm each
• High-strength padlock
• Guides for ash tray (similar to furniture guides or homemade)
⸻
4. Safety and protection:
• All welds should be welded from outside and inside.
• Ventilation holes on the sides of the grill (5–6 pcs Ø10 mm).
• Sharp edges should be smoothed.
• All external elements should be heat-resistant painted (up to 800°C).
• In the folded position, the structure should prevent access to the grill without unlocking.
⸻
5. Result:
• Finished metal product (grill pan + frame + fasteners)
• Drawing with dimensions (if the contractor makes adjustments)
• Wall mounting capability
• Optional: delivery or installation (if the craftsman is from my city)
⸻
Expectations:
• Reliable construction
• Ease of use
• Aesthetics (can be used near the house/garage)
• Suggestions for improvements are welcome
The task was made by chat GPT, in my own words: I need a barbecue for 10 skewers that will hang on a brick wall near the garage. Near it are many multi-storey buildings. I want it to open, unfold, and lock. After grilling, it should be convenient to collect the ash into a bucket and dispose of it, then close the barbecue. I need a complete instruction on how to make it so I can give it to a welder to build and install. It must be very securely attached, not just with anchors.
