| Maximum Height | 40 mt |
| Under Hook Maximum Height | 27.8 mt |
WTO
Our workshop WTO is located in the port of Oltenița (app. 60 km from Bucharest), where we also own a private River Port with access ramps to the river for roll-on and roll-off operations.
| Covered Area | 7.730 sqm |
| Uncovered Area | 71.300 sqm |

National Company “Administratia Porturilor Dunării Fluviale” S.A. granted Walter Tosto WTB the right over ramps usage in the port of Oltenița for roll-on and roll-off operations (agreement n. 2251).
The Roll-on/Roll-off service of the ramps is subject to their availability at the time of request (*)
The ramps are available for rental with the application of the following fees:
• For a single transit 0 ÷ 10 tons – free
• For a single transit over 10 tons – € 90,00/tons (i.e. 124.000 kg = 11.160,00 €)
• Parking for more than 3 days will incur an additional charge of 500,00 € / day
• For boats – 10 lei / day
To use the ramps, please contact Walter Tosto WTB (with at least 15 days’ notice) at the following contacts:
Phone: +40 314.201.060 (Monday to Friday, from 8:00 a.m. to 4 p.m.)
Fax: + 40 314.201.060

The full knowledge and the familiarity with all the existing design codes such as ASME, BS 5500, CODAP, Stoomwelzen, AD Merkblatt and GOST allow us to develop the best design from the mechanical point of view. Furthermore, the in-house presence of FEM experts, together with the several ANSYS licenses, make the Finite Element Analysis a powerful instrument in our hands, for the design of critical parts of the equipment.
In addition to the mechanical design, Walter Tosto WTB has strong skills in the development of the thermal and fluid-dynamic design starting from Process Data Sheets, ensuring all the required guarantees to our customers.
Our design activities include:
• 3D simulations
• Stress analysis by finite elements methods
• Fracture mechanics analysis
• Static analysis in steady and unsteady conditions
• Fatigue analysis
• Creep fatigue damage evaluation
• Thermo-hydraulic design of heat transfer systems
