Date Oct. 10, 1985.A mobile loader of the type used for loading and unloading the cargo holds of aircraft is described. The loader operates by electric motors driving both traction apparatus and loading platform elevation. The loader comprises a chassis having a variable height platform, the platform being connected to the chassis by linkage for maintaining the platform in a substantially level attitude irrespective of platform height, mechanical lifting apparatus for varying the height of the platform with respect to the chassis, an electric motor drive connected by transmission apparatus to the mechanical lifting apparatus for raising the platform, an electrical energy storage (such as a battery pack) for powering the electric motor drive, control apparatus whereby the electric motor drive may be switched to function as an electrical generator to provide retardation of the platform when being lowered, and controllable circuitry to direct the electrical energy generated during lowering the platform into the electrical energy storage.
