Definitions

  • Lifting devices of this type are known in many variants from the prior art. They are used for raising and lowering, as well as transporting various objects or even transporting people.
  • lifting devices Depending on the load to be transported or lifted or lowered, different requirements are placed on lifting devices. If a lifting device is provided for a heavy load or if a load is to be lifted to a great height, a different chassis is advisable, for example, than for light loads and low lifting heights. It is also possible that special environments require special trolleys so that the load can be picked up from the starting point of a transport or delivered to the destination.
  • the different chassis currently make special models necessary, which are often created by converting a series model.
  • the present invention is based on the problem of meeting the different requirements for a chassis of a lift truck.
  • the problem on which the invention is based is solved according to the invention by a lifting device according to claim 1.
  • the chassis of a lifting device according to the invention is of modular design. Modular in the sense that the chassis is composed of several parts. The parts have connecting structures that connect them to one another. Such a modular chassis can be assembled from different parts depending on the requirements in the manner of a construction kit, as long as mutually interchangeable parts have the same connection structures for connection to the other parts of the Have chassis or the pallet truck.
  • the parts can be monolithic.
  • the side parts and the cross member are modules of the chassis.
  • the side parts can be varied to meet special requirements without having to change the cross member.

  • the cross member can be designed monolithically.
  • chassis As a whole, but also the side parts of the chassis are modular. This increases the modularity of the entire chassis.
  • Each side panel comprises several monolithic sections that are interconnected and are modules of the modular side panels.
