Site Prep Before the Frame Arrives
Ground slope and drainage determine more than any published load rating. The frame legs can be trimmed once only, so crews measure twice, cut once and recheck level after the first heavy rain. Asphalt that appears solid in summer often softens after repeated freeze-thaw cycles; one crew had to add extra chemical anchors after the initial winter test. Bolt-down feet require a substrate with verified pull-out strength. On the pilot site the team drilled 12 mm holes to 100 mm depth, cleaned out dust with compressed air, then injected resin and inserted M12 studs. They waited the full 24-hour cure before applying any load.
Cable Paths That Survive 2 a.m. Callouts Power and signal must reach
the screen without creating trip hazards or standing water. Once the display is mounted, chase space inside the frame becomes restricted, so conduit must be placed before the legs are fixed. RJ45 and 230 V tails exit low, then loop upward into the rear enclosure to keep water out if a gland fails. Mini-PCs inside the housing need ventilation that does not draw rain inward; the installer fitted a small louvred vent on the lower rear panel and sealed the joint with closed-cell tape.
Wind Load and Anchor Calculations The pilot confirmed the frame could hold a 3000-nit
IP67 panel without measurable movement in typical UK wind. Chain rollout now hinges on repeatable surveys rather than bespoke engineering each time. Installers template leg lengths and anchor spacing once, then reuse the same kit list. That keeps commissioning time consistent across dozens of locations. - Verify substrate pull-out strength before ordering anchors
- Pre-cut one reference set of legs on the first site - Run full signal path test with actual source before final torque on the screen
Torque Specs and Final
Commissioning M10 leg bolts are torqued to 60 Nm in
a cross pattern. After 48 hours the crew returns to recheck torque because initial ground settlement can loosen the first setting. They also apply a 50 kg lateral force at the top rail and confirm deflection stays under 2 mm before signing off.
Scaling One Site to Multiple Pubs
Repeatable site surveys replace custom design work. The same anchor pattern and leg-length template travel from pub to pub, reducing variation. Spare gaskets and one pre-terminated cable kit ride with each frame so the next location does not wait on parts.
What Usually Breaks First
IK10 glass rating does not protect the rear door or cable glands from staff handling. Spare gaskets travel with the first service visit. Anti-glare coatings remain intact, yet brightness sensors drift; a six-month check prevents midday washout complaints. Practical pricing therefore bundles the frame, anchors, conduit and one spare gasket set as a single line, then adds half a day for unexpected ground work. That figure tracks closer to actual cost than brochure estimates.
