C-TEC uniquely combines the lifting power of mini bags with the lifting height of classic 1-bar bags — all at 12 bar working pressure. Cylindrical design, tool-free multi-bag connection, and integrated load plate. Available in 3 sizes: C-TEC 30, C-TEC 75, and C-TEC 172 (named for their peak starting lift capacity in tonnes).

What Makes C-TEC Different
Most rescue lifting bags trade off between two variables: working pressure (which determines lifting force) and lifting height (which determines how far a load can be raised). High-pressure mini bags deliver enormous force in a compact flat profile but only lift a few centimetres. Classic 1-bar bags can lift 30–40 cm but lack the raw force of high-pressure designs. The C-TEC is Vetter's answer to this compromise.
The C-TEC operates at 12 bar — the same pressure as the S-TEC high-performance bags — giving it a very high starting lift capacity. But its cylindrical design allows it to expand vertically far beyond what flat high-pressure bags can achieve. The C-TEC 30 lifts to 27.5 cm, the C-TEC 75 to 43.5 cm, and the flagship C-TEC 172 to a full 69 cm — comparable to 1-bar bags, at 12 bar pressure.
C-TEC vs S-TEC — Which Series is Right?
Both series operate at 12 bar. The key difference is shape and height capability. Use this table to select the right series for your operational profile.
| Feature | C-TEC (cylindrical) | S-TEC (flat/square) |
|---|---|---|
| Working pressure | 12 bar (174 psi) | 12 bar (174 psi) |
| Shape | Cylindrical | Flat rectangular |
| Max start capacity | 171.8 t (C-TEC 172) | 71 t (S-TEC 71) |
| Max lifting height | 69 cm (C-TEC 172) | 31.5 cm (S-TEC 71) |
| Insertion height | 6.9–11.5 cm | ~4 cm |
| Load plate | Integrated | Flat bag surface |
| Multi-bag connection | Tool-free | Standard connectors |
| Best for | High height + high force | Low insertion + high force |
Choose C-TEC when you need significant lifting height alongside high force — for example, raising heavy vehicles enough to allow extrication access, or lifting structural loads through a larger stroke. Choose S-TEC when insertion height is the primary constraint — getting a bag under a vehicle with minimal ground clearance.
Typical Applications
C-TEC bags are deployed across a wide range of rescue and industrial scenarios where a combination of high lifting force and significant stroke is required:
- Heavy vehicle extrication: The C-TEC 75 and C-TEC 172 are suited to lifting buses, heavy goods vehicles and construction plant where both high starting force and substantial lifting height are needed to create access space.
- Railway and rolling stock rescue: The C-TEC 172 at 171.8 T starting capacity can assist with bogey and carriage lifting operations alongside hydraulic equipment.
- Industrial rescue and machinery entrapment: Industrial presses, collapsed racking and machinery falls benefit from the cylindrical form, which can be positioned in irregular spaces that flat bags cannot access.
- Structural collapse support: Where a void needs to be held open with load-bearing support, C-TEC bags can be positioned vertically to shore loads during victim extrication.
- Tandem lifting: Two C-TEC bags connected tool-free and controlled from a single controller give doubled capacity for symmetric lifts.
