"Tail lift for trucks or the like. ' ¹

The innovation relates to a tail lift for trucks Or the like., With a platform serving as a closure flap and loading ramp, which is made by means of actuating cylinders a closed position in dip open position (s) pivotable is and for the purpose of height movement on höhenverschwenk.baren support arms (lifting arms).

With the previous tail lifts there is still the disadvantage that when the platform is folded down for the loading position, a person standing on it during a platform height change Has no possibility of holding onto outside the crushing hazard area and therefore inadequate safety measures are present.

The task of the innovation is to create an improved tail lift that can be used with simple means for sufficient Safety is ensured and yet the usable space is only insignificantly reduced.

According to the innovation, this is achieved in that on the platform at a distance from the pivot axis one from the platform profile Retaining device that can be swiveled out and locked

Direction, such as support stand (post), support bracket, handrail With scissor linkage support structure or the like., Is arranged.

With a tail lift designed in this way, the usable platform area remains in the loading dock position and still can quickly and if necessary outside the danger zone a hold can be created effortlessly. These Retaining device that can be swiveled into the platform profile also has the advantage that when it is held in the closed position Platform the retaining device does not protrude into the cargo space and thus the loading possibility in none Way impaired.

A preferred embodiment carries on the pivotable The (fold-out) retaining device controls the top control of the tail lift, i.e. it is the iopulse switch eiaer the height movement as well as certain change in inclination of the Platform controlling switchgear attached. This embodiment shows the advantages that the switches (push buttons) the top control are always in the same, protected place and, on the other hand, those from the platform Liftgate functions "lifting" and "lowering" person switching inevitably must always stand outside the crush and shear zones (i.e. outside of danger zones) in order to protect the respective to be able to carry out the desired switching operation - it is achieved that the operator standing on the platform with "up control" of the platform height movement in a safe place and holding on to work.

Further features of the innovation are the other subclaims refer to.}

The subject of the innovation extends not only to that Features of the individual claims, but also on theirs Combination.

An exemplary embodiment of the innovation is shown in the drawing.

Show it:

1 shows a side view of a tail lift arranged on a vehicle with the platform folded down in the open position, from which a holding stand having the switches of the top control is folded out is,

FIG. 2 shows a detail view according to detail "A" in FIGS. 1 and

3 shows, in partial view, a plan view of the platform of the same tail lift, with the retaining stand is folded in (sunk).

A tail lift according to the invention for trucks or the like. has a platform 1 serving as a closure flap and loading ramp, which is attached to a pivot axis 2 by means of hydraulic cylinders (Lifting cylinder) 3 vertically pivotable lifting arms 4 supported and by means of hydraulic cylinders (lock cylinders) 5 around a pivot axis 6 relative to the lifting arms 4 is pivotable. The connection to the vehicle, especially the truck chassis 7 » A support frame / support bracket 8 is used.

IAt a loader standing on platform 1 during the platform elevation movement outside of danger zones, i.e. QtEtsch and / or shear points to provide a secure hold, on the other hand, however, if necessary, the entire loading area of the To be able to use platform 1, is on the platform 1 in the larger Distance (which prevents the loader from being crushed or the like between the platform 1 and the vehicle loading space 9)

to the pivot axis one from the platform profile upwards Swiveling out and lockable retaining device 10, such as a support stand (post), bracket, handrail with Scissor linkage support structure or the like. Arranged. In. The retaining device is particularly simple and preferred 10 formed by a support post (stand) and at the same time carries switch 11 of an upper control, i.e. a switching device that can be operated from the platform 1, the retaining post is preferably as a Tube (for example, square tube) running that receives the electrical lines connected to the switches 11. To lock the retaining post, a bolt, preferably a sliding bolt 12, can be provided, which is inserted into the Pfostenschweiikweg can be moved into and both in-Bchwerikter as well as in the folded out end position of the retaining post (1) a safeguard against unintentional pivoting represents (see. Fig. 2 and 3). As can be seen from Fig. 3, the retaining device 10 is in a near a platform side edge 1a extending recess 1b of the particular from several juxtaposedeii box hollow profiles composite platform provided collapsible. The support post pivot axis is numbered 13
