- the said link 25 extends above the cable drum 15 approximately at the operator's stomach or chest height Unit to be able to move easily.
- the handlebars can extend together with the wheels 20 to one side of the cable drum 15, so that an imaginary connecting line between the handlebars 25 and wheels 20 can form approximately a tangent to the cable drum 15.
- the focus of the cable drum 15 is in the state supported on the ground, in which the support arms 23 also touch the ground, viewed from the link 25 slightly in front of the wheels 20 or slightly in front of the chassis axis, so that the weight of the cable drum 15 tries to tilt the unit slightly forward with respect to the chassis 19 and part of the weight rests on the support arms 23.
- the geometry of the drum support frame 18 is adapted to the receiving compartment 17 in such a way that the cable drum unit 1 is lying fits perfectly into the receiving compartment 17.
- the support portion 22 and / or the support arms 23 can extend from the chassis 19, when this stands up on the frabo the 13, slightly obliquely from the cable drum 15 up to the ceiling 14 of the receiving compartment 11 and are in contact with it. Since the center of gravity of the cable drum 15 is not above the chassis axis 19, but is spaced from it, the drum support frame 18 rotates until the support section 22, in particular the support arms 23 on the ceiling 14 and / or the link 25 on the shelf 13 pending so that the drum support frame 18 is clamped in the receiving compartment 11, at least rests without play.
- further fastening means can be provided, for example latching elements that lock the handlebar 25, such as latching clasps into which the handlebar 25 can be clipped.
- tensioning elements such as tension belts or tensioning levers or clasps, or adjustable fastening elements such as screw clasps can be provided to keep the cable drum unit 1 safe in the drum uptake 10 even when the ferry is jerky.
- a cable deflection 26 can be provided on the crane 2, in particular on the drum holder 10, which can advantageously extend at a position facing the chassis 19 and / or the support arms 23 in the position attached to the crane .
- the cable deflector 26 can be arranged on a receiving compartment side of the receiving compartment 11 which faces the chassis 19 and the support frame 23.
- the cable deflection 26 can, for example, have several deflection rollers 27, which can be arranged upright and lying in pairs, spaced apart from one another, in order to be able to deflect the cable to be unwound in different directions.
- the cable drum 15 can be rotated relative to the drum support frame 18 by a drum drive 28.
- Drum drive 28 include, for example, a hand crank 29 which can be fastened on a drum shaft 30 in a rotationally fixed manner.
- the drum drive 28 can also comprise a coupling of the drum shaft 30 to one or both wheels 20 of the chassis 19.
- the drum drive 28 can include a chain or belt drive, with a drive pinion or drive pulley attached to the drum shaft 30 in a rotationally fixed manner and a second drive pinion or drive pulley can be fixedly attached to one of the wheels 20.
- the two pinions or the two drum disks are advantageously matched to one another in terms of their circumferential diameter in such a way that when the cable drum is moved while the wheels 20 rotate, the cable drum 15 rotates so quickly that the path covered by the chassis 19 is approximately the same as that unwound or coiled cable length.
