Definitions

• the invention relates to a Abstützverbreiterung for trucks, especially for trucks with a loading crane, with at least one between a
• Transport lock for the side arm, wherein the transport lock has at least one locking device for locking the at least one side arm in the transport position and a signal device which can be activated by the side arm located in the transport position.
• Such Abstützverbreiterungen serve to increase the footprint of the parked vehicle and thus increase the stability of the same, which is particularly important in the manipulation of goods by means of a loading crane arranged on the loader crane of great importance for operational safety.
• the support extensions are equipped with a transport lock. This has in addition to a locking device and a signaling device that indicates the operator in the driving position that the side arm is in the transport position.
• An object of the invention is therefore to provide a generic Abstützverbreiterung, in which the signal device in addition to the transport position of the side arm additionally indicates the state of the locking device.
• the signaling device is coupled to the at least one locking device such that the locking of the locking device leads to an actuation of the signaling device.
• an operator in the driving position of the truck not only indicates whether the side arm is in transport position, but additionally signals whether the side arm is locked in the transport position.
• the signaling device has a limit switch, which is designed and arranged to detect the transport position of the side arm, wherein it has been found to be advantageous when the signal device to the at least a locking device is arranged and advantageously the at least one locking device acts automatically. This ensures that the signaling device is only actuated when the side arm is locked in the transport position.
• the at least one locking device is arranged according to a further embodiment of the invention advantageously to the plane of movement of the side arm substantially normal pivoting on the load vehicle. This can for example be realized constructively in that the locking device is formed by a leaf spring.
• the signal device can be designed to detect the position of the engagement element in the receptacle of the locking device. This ensures that the signaling device is activated only when the engagement element arranged on the side arm is actually in the receptacle of the at least one locking device, i. when the side boom is in the transport position and locked in it.
• the receptacle can be formed according to a further embodiment of the invention of a passage opening and the locking means comprise a rotatably mounted closure member for receiving.
• a user-friendly solution which also increases the reliability, is achieved according to a preferred embodiment, when the closure element is arranged such that upon displacement of the side arm in the transport position, a pivoting of the closure element by means of the engagement member of a recording occlusive position in a recording releasing Position takes place, and vice versa.
• the closure element drops when releasing or opening the at least one locking device down, whereby the receptacle is closed and the engagement of the engaging member is prevented in the recording, so that when pulling the side arm, the at least one locking device is not held in a position releasing the side arm so that an operator can pull out the side boom with both hands.
• the closure element is pivoted, preferably by means of an arranged on the side arm engagement element in a recording releasing position and thus after reaching the transport position of the side arm, the receptacle for entry of the engagement element free, thereby subsequently the signal means the position detects the engagement element and outputs a corresponding signal or forwards.
• the transport lock may comprise at least one further separate locking device, thereby ensuring that the Abstweilverbreiterung is locked with two separate locking devices in the transport position.
• at least one of the two locking devices can act automatically to increase the reliability and at least one of the two separate locking devices should be secured against unintentional loosening, e.g. by Federsplint.

• the Abstweilverbreiterung 1 consists essentially of the displaceably mounted side arm 2 and the transport lock 3.
• the side arm 2 in the illustrated embodiment, a crossbar 12 which is slidably mounted in the cross member 14, and a support bracket 11.
• an engagement element 9 is formed on the side arm 2.
• the transport lock 3 comprises a locking device 4 for locking the side arm 2 in the transport position shown in Fig. 1a.
• the engagement element 9 engages in a receptacle 8 formed as a passage opening of the locking device 4.
• a signal device 6 is fixedly arranged on the locking device 4, which has a limit switch 7 with a sensor 13 for detecting the position of the engagement element 9.
• FIG. 1b shows a cross section along the line ZZ of FIG. 1a, wherein it can be seen that the engagement element 9 arranged on the side arm 2 rests on the sensor 13 of the signal device 6 in the transport position of the side arm 2, whereby a signal is generated which is electrically, is forwarded pneumatically or mechanically.
• non-contact devices - such as Photocells and proximity switches or initiators - can be used.
• the locking device 4 is arranged laterally pivotable on the cross member 14 in the direction of the arrow R to the direction of movement R of the side arm 2. To the locking of the side arm 2 in the
• the locking device 4 formed in the embodiment shown by a leaf spring in the direction of arrow must be pivoted until the arranged on the side arm 2 engagement element 9 is out of engagement with the receptacle 8 of the locking device 4, so subsequently the side arm 2 in the direction of movement R can be pulled out of the cross member 14.
• Figs. 3a to 3d is dispensed with the repeated reference identical components, wherein the embodiment according to FIGS. 3a to 3d of the embodiment according to FIGS. 1a to 2 essentially by the arrangement of another, of the locking device 4 separate locking device 5 different. That is, the Abstweilverbreiterung 1 shown in Figs. 3a to 3d comprises two independent locking devices 4, 5, wherein the locking device 4 acts automatically and is coupled to a signaling device 6, so that locking the locking device 4 to an output of a signal that Information about whether the side arm 2 is locked in its transport position leads.
• Locking device 5 is unlocked while the locking device 4 is in the locked state, that is, the engagement element 9 of the side arm 2 is in the receptacle formed by a passage opening 8th arranged. This position of the engagement element 9 is detected by the sensor 13 of the signal device 6 and forwarded a corresponding signal from the limit switch 7.
