Description

LIFTING DEVICE

FIELD OF THE INVENTION

The invention relates to a lifting device to be placed in an O2 vehicle category trailer, which facilitates loading and unloading of loads. An O2 vehicle category trailer is a trailer with a total weight class of < 3500+75 kg, which is suitable for, for example, being transported by a van.

BACKGROUND OF THE INVENTION

— When loading and unloading a trailer, it is often necessary to use some kind of lifting device, which is often a forklift or some other lifting device. However, there are often situations where lifting devices are not available, in which case loading and unloading the load has to be done manually. This is often a slow and physically demanding operation, which has resulted in many types of accidents.

IMAGE LIST

The invention is described in detail below with reference to the accompanying drawings, in which Figure 1 shows an exemplary view of the lifting device from the left side of the trailer, Figure 2 shows an exemplary view of the lifting device from above the trailer, Figure 3 shows an exemplary view of the lifting device from the left side of the trailer, with the lifting device packed in its driving position. 19

The lifting device according to the invention operates when loading a load onto a platform by turning the horizontal boom to the load next to the platform and attaching the load to the lifting bracket of the horizontal boom or to the lifting eye of the extension part of the horizontal boom. The load is lifted into the air to a suitable height using a working cylinder or winch and the load is moved to the desired position on the platform using the horizontal boom and lowered onto the platform. Lifting the load off the platform is done in the reverse order.
