- a swivel push device 11 arranged laterally relative to the driver's cab 9, i. H. in Fig.
- Has additional mast (additional mast) 13 on which a load suspension device (Fork) 1 5 with its bracket 16 adjustable in height relative to the driver's cabin 9 is performed.
- the additional mast 13 can be together with the load handling device 15 are pivoted about an axis 17 by approximately 180 °.
- a roller bearing 18 designed as an incremental angle encoder is arranged, whose rotatable outer ring 19 as a roller body with a roller axis perpendicular to the lifting direction of the upper mast part 7, the Roller body 19 with its circumference on a surface 21 of the lower Mast part 5 abuts, one in the lifting direction of the upper mast part 7 extending path forms on which the roller body 19 at telescopic Displacement of the upper mast part 7 relative to the lower mast part 5 rolls.
- the roller bearing 18 is attached to the mast part 7, that the roller body 19 is resiliently biased towards its path 21 and is therefore always in contact with the train.
- Fig. 1 the upper mast part 7 is shown partially extended, while the cabin 9 is in its uppermost position relative to the upper Mast part 7 is shown.
- the load handling device 15 is located in its lowest position relative to the additional mast 13 and is for 1 side swiveled.
- the hydraulic Drive means for the elements 7, 9, 11 and 15 are not shown.

- reference transmitters for the Position measuring device provided.
- it is proximity sensors 23 and 25, which are attached to the lower mast part 5 are arranged and one on the upper mast part 7 at a predetermined location attached reference transmitter element (Mark) 27 a respective reference signal to the evaluation circuit submit.
- the evaluation circuit can use the reference signal from Check the position sensor derived from the angle encoder 18 and if necessary correct.
- the reference value providers can also be used are to calibrate the measuring range of the position measuring device, wherein the upper mast part 7 starting from its lowest basic position is extended so that the reference value transmitter element 27 in succession is guided past the proximity sensors 23 and 25.
- the evaluation circuit represents the number of 18 from the angle encoder per channel emitted pulses between the occurrence of the first reference signal from the proximity sensor 23 and the occurrence of the second reference signal from the proximity sensor 25 to the respective number of pulses the predetermined distance between the proximity sensors 23 and 25 to normalize so that a very exact assignment between changes in position of the upper mast part 7 and changes in the angle of rotation Roll body 19 can be taken.
- the sensors 23 and 25 can as inductive proximity sensors, light barrier switches or the like be trained and possibly take on additional functions, as part of an end position detection circuit.
- a single reference sensor for example the reference sensor 23, get along, for example, at a predetermined distance above the lowest possible position of the reference element 27 is arranged, the the reference element 27 assumes when the upper mast part 7 has completely moved into its lowest basic position.
- Another Possibility is to use a single reference encoder at over which the reference sensor in question and the reference transmitter element cooperate a predetermined stroke section.

- the upper mast part 7a is shown in Fig. 3 in a position in which it by a predetermined reference distance r from its lowest possible Rest position is raised.
- the sensor 23a at the reference distance r changes its output signal when the mast part 7a over the reference path r is moved upwards or again when moving downwards reaches the reference range.
- Fig. 3 is the upper mast part 7a shown in a snapshot, in which it is a signal change on the Sensor 23a causes. From the signal state of the sensor 23a clearly derived whether the mast part 7a outside the Reference distance range r is and that it is to be lowered in order to its lower end in the reference path area r for referencing contribute.
- Fig. 3 also shows the possibility that the angle encoder 18a on the fixed mast part is rotatably arranged and set in rotation when the movable mast part 7a moves up or down becomes.
- Another angle transmitter 18 ′′ corresponding to the angle transmitter 18 ′′ is on an element 16 which is firmly connected to the load suspension device 15 arranged, the associated roller body 19 "on a vertical running path of the additional mast 13 rolls when the load handler 15 is raised or lowered relative to the additional mast 13.
- the evaluation circuit also evaluates the pulse signals of the latter Angle encoder 18 "and can from the respective angle encoder information the lifting height of the load-carrying means 15 relative to the driver's cab 9 and determine relative to the mast parts 7 and 5.
