1. Four Critical Safety Updates Introduced in EN 1004-1:2020
EN 1004-1:2020 eliminated the old 2.5 m minimum height exemption, capped vertical spacing between consecutive trapdoor decks at 2.25 m, required collective guardrail protection before stepping onto any new platform level, and strictly enforced 8 m outdoor / 12 m indoor freestanding limits.
2. Effective Base-to-Height Ratio, Outriggers & Dual-Brake Castors
All SerMimar Mobile Towers feature Ø200 mm dual-action braked castors with leveling spindles and 4-point telescopic outriggers (SM-M wheel & stabilizer series) rated to Class 3 (200–250 kg/m²).
