  • the pallet truck is raised by lowering the load handler.
  • the load is transferred to the corridor level via the support carriage.
  • the support truck so that the raised pallet truck can be lowered to the higher level by lifting its load-carrying means, the support car is lifted after the lifting of the high-lift beam by continuing to lift the load-carrying means.
  • the underframe of the support carriage which is disturbing when the support carriage is raised due to the fact that the support level has passed underneath it, is brought out of the interference area, for example, by pivoting or shifting, and is reset again after it has been lifted above the set-down level. Then the support carriage is also placed on the depositing level by lowering the load handler of the high-lift truck and the combination is pushed into the desired position.
  • This is achieved solely by means of a coupling option, by means of which the front ends of the load-carrying means of the high-lift truck can be non-positively connected to the vertical column frame of the support truck, at least for lifting, gravity being an essential force.

  • a visor nose is used for better insertion.
  • the simplest version can be that the upper flange of the insertion shoe is extended against the direction of insertion.
  • a screwing clamping device can be used to switch off a game that is disruptive when lifting.
  • the load suspension means can be inserted from one side as well as from the other side.
  • the opposite direction of insertion offers advantages for some transport problems. Since after the lifting truck has been set down, it is often desirable to block the possibility of travel in one direction of travel - for example when moving on the loading level of a truck, the ability to move against the direction of travel - it is expedient to provide a locking device in at least one claw of the lifting truck.
  • This claw advantageously designed as a single-acting inclined brake lever, can can advantageously be triggered by a release finger provided on the insert shoe, since the chassis claws of the lift truck are spatially in the immediate vicinity of the insert shoes when the lift truck is raised.

  • the steering rod which also serves as a drawbar, acts on the steering saddle or directly on the wheel or roller set when the steering is active; with passive steering, for example by means of caster roller set, the handlebar is only a drawbar.
  • the pallet truck is a fork lift truck supported by support claws below the load suspension means, in which the load suspension means protrudes to a certain extent beyond the support or travel claws, this dimension at least the diameter of the rollers or wheels plus the profile width of the vertical struts of the column frame of the support carriage.
  • the support claws take over part of the load picked up by the load suspension devices.
  • the height of the upper edge of the longitudinal struts of the base frame of the support truck is at most equal to the lifting height of the conventional pallet truck.
  • the longitudinal struts can serve as receptacles for loads, in particular for palletized loads, which can be placed on the longitudinal struts by a pallet truck and can be picked up again by these.
  • support rollers are provided on the support or driving claws of the lifting truck which have a slight ground clearance when the rollers stand on the floor.
  • additional support rollers with locking devices are provided. These support rollers make it possible to place the pallet truck that has not yet fully moved into the loading space of the truck on its loading surface with the support rollers. As a result, its load handler protrudes beyond the rear of the truck, which makes it easier to lift the support truck.

  • These support wheels are particularly important if a wheel or a roller or a wheel set or a roller set is arranged centrally on the lower cross member of the column frame of the support carriage. When cornering, the column frame tilts and the inclination is limited by the support wheels.
  • the insertion shoes are designed to pivot upward about a horizontal axis at the upper end of the vertical struts of the column frame of the support carriage and can preferably be fixed in the pivoted-up position.
  • the insert shoes protruding into the loading area interfere with the transport of high loads. This bypasses the embodiment in which the insert shoes are pivoted up about a horizontal axis. Falling back is prevented by locking in the swiveled position.
  • a preferred embodiment is given in that the lift-lowering and possibly travel drives and an existing locking device of the lift truck are designed to be electrically controllable, the electrical command element being removable from its place on the lift truck and by means of a spiral cable or the like.
