  • a generic skew elevator is proposed which may be provided on a chassis so that this unit can be used efficiently overall for roofer work or relocation.
  • the control of this ladder-slide unit is characterized by the fact that several displacement and speed sensors are used in a system.
  • respective cable drums with incremental encoders are connected so that sen sensors at the upper end of a package of Auslegeierin can be dispensed with, since the sensors are arranged for the position of the transport carriage relative to the conductor arrangement at the bottom of the bottom ladder.

  • This having the laser sensor measuring device can be positioned in structurally variable mounting positions on a base assembly in the field of Auslegeimplantation on the inclined elevator, wherein a corresponding reflector is arranged to track the movement in the transport carriage on this.
  • the function of the inclined elevator with only one laser sensor is guaranteed even when the extension length of the extension elements reached during the raising operation is manually entered in the area of the control unit, so that subsequently for the electronic distance measurement a corresponding limit value is defined as system-internal reference quantity. Due to the concept of "direct tracking" of the transport carriage and the hydraulic drive system of the inclined elevator with less control components is cheaper executable because additional control components, for example, to compensate for changes in position during loading, are unnecessary.
