Cantilever lift

The platform has an insulating layer arranged between a supporting structure (13) and a covering layer (15) of a platform part (10). A vacuum insulating material is provided in the insulating layer that is circumferentially covered by an edge profile made of plastic material. The covering layer consists of a metallic sheet i.e. aluminum sheet, and completely covers the insulating layer and/or partially covers the edge profile. The covering layer is screwed or glued with the edge profile, and the supporting structure includes a tank, where the layers and the edge profile lie in or on the tank. An independent claim is also included for a vehicle comprising a sealing unit.
