To u r é c h a f : k e y i n g b e a m s Moving Towers can be moved using shifting trolley or by lifting them. For lifting with a crane, use 4 additional slings to facilitate attachment from the deck. An overhanging deck must be installed at the top of towers for keying beams Using keying guardrails 1.00 m and 1.50 m keying guardrails protect workers while they are keying beams. Advantages: - Speed and simplicity, - Curved guardrail for passing I-beams, - Enables the towers to be moved. Clearance under the beams All four keying guardrails lowered. Fitting the beams 4 keying guardrail raised. Fit the 4 keying guardrails from the outside of the tower (towers with up to 2 frames). Node formwork The keying guardrail can be lowered on the beam side. Safe to assemble and dismantle from a temporary deck (towers with 3 frames or more).
