A furniture lift or construction lift is a chassis-mounted modification of an inclined lift, in which a platform can be moved on a telescopically extendable support. The chassis can be a truck or a trailer. These are usually mounted on chassis with a permissible total weight of 7.5 t and can therefore still be driven with the driving license class 3.
One of the first manufacturers of construction hoists was the company Klaas. The first construction hoists were manufactured there in 1947.
Since 1974, mobile furniture lifts, derived from mobile inclined construction lifts, have been equipped with modified conveyor carriages, forming so-called "furniture platforms." When extended, these can also transport large pieces of furniture. The most important distinguishing feature between furniture lifts and construction lifts is the conveyor carriage. In furniture lifts, this carriage is a closed box with foldable side panels. This allows even large and bulky items to be transported. In construction lifts, the side panels of the conveyor carriage are fixed.
Due to the special requirements (also due to the StVO ) regarding mobility, load-bearing capacity, telescopic height and dead weight, furniture lifts have been further developed into high-tech machines.
