Definitions

  • the present invention relates to a handling system for the maintenance of transport vehicles according to the preamble of claim 1.
  • Dolly in particular drawbar-guided, are used to transport high loads on the road or in-house transport. Because of the high loads to be transported, regular maintenance is also required for the transport vehicles used only in internal transport. Due to the high weight of the trolley, especially with payloads greater than 1t, maintenance on these are very expensive, since the trolley must be lifted by a suitable lifting device. The maintenance work to be performed by a person takes place below the trolley in an overhead position. In particular, wheel changes are thus not feasible by a single person, since the individual wheels may have a weight of about 15-80 kg.
