Scotlifts in Dumbarton can supply and fit the SL400B. The SL400B gives a good all round seal as the SL400, but is designed without the insulated panels making it a cost effective option if temperature control is not key.
Once the vehicle is docked the shelter is switched on activating the fan and the head and side bags inflate against the vehicle creating a good all round seal. Loading or unloading of the vehicle can then take place with little risk of the goods or operatives being affected by the outside environment.The standard size is 3600mm wide x 3700mm high x 900mm projection, however this can be changed depending on the vehicles using the bay.
Scotlifts airbags are manufactured from 1000d cordura type material which is a hardwearing, woven nylon coated fabric with a high tear resistance. The shelter sides are manufactured from box section and a PVC type material. The fan used is normally a three phase centrifugal fan that fully inflates the bags between 10-20 seconds. Once the fan is deactivated the bags will return to their deflated position behind the storage curtains by a counter balance weight system.
If temperature control is important to the bay, for example cold storage, then the standard DR400 would be a better option, with its fully insulated side and head panels.
