Definitions
- the present invention relates to a crane, in particular a tower crane, with a crane boom, from which a load hook can be raised and lowered via a hoisting rope, and an electrical power supply to the load hook and / or a possibly provided trolley movable on the crane jib.
- an electrical power connection available at the load harness or load hook for example, to operate electric lifting magnet for magnetic lifting tasks, or to use other attachments with, for example, electrical servomotors on the load hook.
- the crane has a trolley on the boom, as is the case, for example, with tower cranes, it is sometimes necessary or helpful to have a power connection to the trolley, either to be able to forward the current to the load hook from the trolley via a spring drum, or to power other consumers on the trolley, for example, headlights or other electrical appliances.
- the present invention is therefore an object of the invention to provide an improved crane of the type mentioned above, which avoids the disadvantages of the prior art and the latter further develops in an advantageous manner.
- electrical energy is to be provided in a simple and efficient manner on the load hook and / or on the trolley of the crane, without impairing the ease of installation and to create excessive, bulky space on the boom.
- the electrical power supply takes place drove to the load hook and / or to the trolley, at least partially via a running, in crane operation intended tensile forces transmitted rope.
- the rope is designed as an electric traction cable, which can simultaneously transmit tensile forces and transport electricity.
- a trolley traveling the trolley can be made electrically conductive and can feed a power connection provided on the trolley.
- an inner Katzfahrseil which connects the trolley with an inner, usually hinged to a tower end or a deflection roller provided there, electrically conduct in the above manner or be designed as Elektrozugseil, so that the power supply or current collector on the Trolley is electrically powered via the interior Katzfahrseil with which the trolley is pulled or moved to the inner end of the crane jib out.
- an outer Katzfahrseil which connects the trolley with an outer, cantilevered boom end, be designed as an electric traction cable to supply the trolley with power.
- the outer Katzfahrseil may be formed as a conventional traction cable, which does not form an electric traction cable, whereby the outer Katzfahrseil compared to an electric traction cable can be thinner and lighter, which weight advantages on the outer, more critical for the moment load boom half brings.
- the power supply in the electrically conductive Katzfahrseil can be done in an advantageous manner in the area of Katzfahrseilwinde.
- the Katzfahrseil may be connected to the trolley winch with Stromeinspeiseschn, which may preferably have a slip ring transformer.
- the Katzfahrseil be struck on the trolley winch and with its at least one electrical conductor on a rotating with the wind power connection be connected, which can be fed via said slip ring transformer.
- an electric cable can be provided, which can participate or compensate for the changes in distance by means of a spring drum, by lifting and lowering the load hook arise.
- said spring storage drum is not provided on the trolley, but on the load hook or a thereto attachable attachment.
- a plug connection for example in the form of a socket or a plug, for connecting the electric cable, which leads to the load hook, may be provided.
- a power connection provided or required in the region of the load hook can also be fed with electrical energy directly via the hoist cable leading to the load hook.
- the hoist cable can be formed in a development of the invention electrically conductive or as an electric traction cable comprising at least one electrical conductor.
- a power supply to the load hook directly via the hoist rope is particularly advantageous if the boom of the crane, from which the load hook can be lowered and raised, is an adjusting boom, for example in the form of a luffing luffing jib and / or a telescopic telescopic jib, and / or in connection with a single-strand hoist rope insertion and / or a multi-strand Hubseileinscherung in which a Hubseilende posted on the load hook and / or connected to an associated attachment.
- the hoisting rope is designed as an electric traction cable
- the electric current into the hoisting cable can advantageously be fed in the area of the hoist winch.
- the hoist rope can be connected in the region of the hoist winch with current feed means, which can comprise a slip ring transformer.
- current feed means which can comprise a slip ring transformer.
- Fig. 1 a schematic side view of a trained as a tower crane
- Fig. 2 a schematic side view of a trained as a tower crane
- Fig. 3 is a schematic cross-sectional view of a trained as Elektrozugseil Katzfahrseils or hoisting rope, showing the arrangement of the electrical conductor in the cable core.
- the crane 1 can be designed as a tower crane and have a tower 2, which carries a cantilevered boom 3.
- the tower 2 can sit with its lower end on a revolving stage 4, which is an upright axis is rotatable and supported on an undercarriage 5, which may be designed to be movable as a truck or otherwise, but may also form a rigid, non-movable support base.
- the boom 3 can be braced by means of a bracing 6, wherein the bracing 6 can optionally be designed to be adjustable in order to be able to rock the boom 3 up and down, as FIG. 2 shows.
- the crane 1 can in particular be designed as a fast-erecting crane, the tower 2 of which can be telescoped and the boom 3 of which can be folded and / or telescoped, so that the tower and outrigger can be folded together to form a transport package capable of transporting the road.
- a trolley 7 can be mounted longitudinally movable on the boom 3, which can be moved back and forth by means of a trolley 8.
- An inner Katzfahrseil 8i leads from the trolley 7 via a guide roller 10 at the inner, near the tower end portion of the boom 3 to a Katzfahrwinde 9, while an outer Katzfahrseil 8a leads from the trolley 7 via a guide roller 10 at the outer end portion of the boom 3 to said Katzfahrwinde 9 ,
- the inner Katzfahrseil 8i be electrically conductive or designed as Ele- rozugseil to transport electrical power to a power connector 1 on the trolley 7.
- the power feed into the Katzfahrseil 8 can be done on the Katzfahrwinde 9, the current feed can be done by means of suitable Stromeinspeisesch on the Katzfahrwinde, for example in the form of a Schleifringübertragers.
- a corresponding electrical installation with residual current circuit breaker 12 is provided and connected to the Katzfahrseil 8, for example in the region of said Stromeinspeisesch on the Katzfahrwinde.
- an electric cable 14 can be provided between the trolley 7 and the load hook 13, the electric cable 14 being connected, for example, to the power connection 11 at the end of the trolley Katzfahrseil can be connected, for example via a corresponding male / female connection or other releasable power coupling means.
- a spring cable drum 16 can be provided on the load hook 13 or advantageously an associated attachment 15, cf. Fig. 1.
- a consumer or a power connection 17 on the load hook 13 or an attached attachment can also be supplied with electrical energy directly via the hoist rope 18, in which case the hoist rope 18 is designed to be electrically conductive or as an electric traction cable ,
- the hoist rope 18 is guided by means of a Einstangeinscherung to the load hook 13.
- the cable guide is advantageously such that one end of the hoist rope 18 is struck on the load hook 13 or the end is connected to said power connection 17 in the region of the load hook 13.
- the power supply to the hoist rope 18 can be advantageously carried out on the hoist winch 19, wherein here in the appropriate manner - as described for the Katzfahrwinde - Stromeinspeisesch may be provided for example with a slip ring transformer. Corresponding electrical installations with a residual current circuit breaker 12 may be provided accordingly.
- the electrically conductive trolley 8 or hoist rope 18 can comprise at least one electrical conductor 20 embedded in the cable core. tet is surrounded by a plurality of outer strands 21, which can serve as a protective conductor.
- control switches 23 or other input means which are preferably freely programmable, can be provided at the control station 22 of the crane or at another suitable location in order, for example, to control implements on the load hook 13 via radio.
- Corresponding switches or input means can alternatively or additionally also be provided on a radio remote control of the crane.
