Where a fixed shoring tower needs the right combination of post lengths for each slab height, a Hybrid Support prop telescopes. MV4 covers 2,500–4,000 mm and MV5 covers 3,500–5,000 mm, so a single item on the delivery note handles a range of soffit heights.
Both are built from SGT550 (STK700) high-strength steel — an outer tube of Ø70.0 mm × 2.3T over an inner tube of Ø60.5 mm × 2.3T.
| Product | Min. Length | Max. Length | Unit Weight |
|---|---|---|---|
| MV5 | 3,500 mm | 5,000 mm | 22.0 kg |
| MV4 | 2,500 mm | 4,000 mm | 19.0 kg |
| Tube | Material | Diameter | Thickness |
|---|---|---|---|
| Outer | SGT550 (STK700) | Ø70.0 mm | 2.3T |
| Inner | SGT550 (STK700) | Ø60.5 mm | 2.3T |
The flange is repositionable along the prop, so ledger connectors go where the layout needs them rather than at fixed welded centres.
Hybrid Support uses the same ledgers, U-head jacks and primary beams as System Shoring, so yards can stock one set of secondary components across both systems.
