Cantieri Navali di Sestri: “The lockdown has led to the rediscovery if small and medium boating and the importance of refitting”
- 8 September 2020
The Sestri Shipyard has installed a 300-tonne travel lift. This is a type of crane used to launch and haul superyachts which, thanks to the refitting work carried out at the shipyard under the guidance of Fulvio Montaldo, find their new beauty and modernity.
Equipment of this type allows for the hauling onto land and launch of pleasure yachts up to 40 metres in length. The travel lift was supplied by Ascom Handling Equipment Specialist spa from Formigine (Modena).
Here are a few more details. The model installed is a BHT 300 and has a nominal load of 300 tonnes. The width of the basin is 10.5 metres and weighs around 97 tonnes on its own. The full load transfer speed can be set by the operator from 0 to 1.20 km/h, while the full load lifting speed is 1.60 metres a minute. At full load the travel lift can handle an incline of 3%.
The machine exerts a pressure on the ground of 10kg per square centimetre and has eight OTR 24.00-35 tyres. It has 4 driving wheels and 4 idler wheels, all which can be steered. There are also two fixed lifting points and six mobile ones. Yachts can be “wrapped” by 16 total straps, each one with a maximum length of 16 metres. It also has 8 independent and synchronised winches.
All the components of the structure, in particular those in steel, are analysed by calculation programs which divides them into an infinite number of pieces, so as to evaluate the stress on all parts. The lift works using a Volvo Penta diesel engine with liquid cooling, a maximum range of 3000 rpm and maximum power of 175 kw and 6 in-line cylinders. The capacity of the fuel tank is 300 litres.
