DE10354685A1 - Tine, for a forklift truck, has a wear unit fitted to the under side at the rear end in a release mounting to increase the tine working life - Google Patents

Abstract

The tine, for a forklift truck, has a tine shaft (1) with a rear section (2) to be attached to the fork carrier. The rear end of the tine is bent into a kink (3) transit into the vertical rear section. A wear unit (6) is fitted to the tine in a release mounting at the under side of the kink transit. The leading end (V) of the wear unit fits into a socket at the tine, and the trailing end (H) is secured by a screw bolt (7) so that the wear unit is partially embedded into the tine. The wear unit is of a different and wider material from the tine, and can be fitted with an integrated sensor.

Description

The The invention relates to a fork tine for a truck, with a for receiving a load provided steerer, one for attaching the fork tine at a height-mobile Gabelträger provided fork back and a fork bend connecting the fork stem with the fork back.

The Service life of forks is mainly determined by wear, in the fork bend on the underside of the fork tine thereby shows that the fork tine on the support surface (road, shelf, etc.) is moved and therefore subject to abrasive wear. It is therefore known fork tines in the fork bend with a wear volume to provide a higher To achieve service life.

Of the present invention is the object of a fork prong of the type mentioned above to provide their life further increased is.

These Task is inventively characterized solved, that in the area of the underside of the fork bend a wear element solvable attached to the fork tine.

By an exchangeable wear element is the wear volume independent in the kink area from the rest State of use of the fork tine. Because the wear element is multiple exchangeable leaves itself the life / service life of the fork prongs according to the invention significantly extended. This reduces the operating costs of a forks according to the invention equipped truck.

Around a quick and easy replacement of the wear element to enable this is expediently in the front area by means of a plug connection and in the rear area connectable by means of a screw connection with the fork tine.

Provided the wear element at least partially embedded in the fork tine, which increases Safety against stripping of the wear element at ground contact the Fork and simultaneous movement of equipped with the fork tine Industrial truck.

According to one advantageous development is provided that in the back area of the wear element at least one screw in a bore of the wear element is arranged and in the front area on both sides in each case a lateral Contact point on the wear element is formed in the region of the connector, against a contact surface of the Fork is present. As a result, the wear element in the longitudinal direction and guided sideways.

By the already mentioned Screw connection can be applied to a bias, so that a sufficiently tight fit of the wear element in the vertical direction can be achieved.

It turns out to be cheap when the wear element made of a different material than the fork tine. Thereby can particularly wear-resistant materials are used, their use elsewhere on the fork tine for functional and / or cost reasons not possible is. The wear element can also - regardless of Rest of fork - special manufacturing process be subjected to such. hardening, remunerated Coating.

Finally are by the use of a deviating from the fork tine material also additional Functions possible, z. B. spark protection, cushioning, wear protection the support surface, on which the fork tine is placed wear protection of the wear element against chemical influences.

The constructive design of the wear element can in shape (width, thickness, etc.) and execution (material, manufacturing processes etc.) without special difficulties on a special application be coordinated. So it is z. B. possible that the wear element wider than the fork tine. Here, the wear element serve as an adjustment aid.

According to one other cheap Embodiment of the invention is at least one sensor in the wear element integrated. It may be z. B. to a ground contact sensor act or a lift height sensor. It is also possible, to integrate a sensor that serves as a wear indicator and thus indicates when the wear element is replaced must become.

Further Advantages and details of the invention will be described with reference to the Schematically illustrated embodiments illustrated embodiment. there shows

1 a side view of a fork tine,

2 a plan view of the fork prong according to 1 .

3 a side view of the bending region of a fork prong invention and

4 a partial top view of the fork in accordance with 3 ,

The in the 1 and 2 illustrated prior art fork tine consists of a steerer 1 and a fork back 2 that by a fork bend 3 connected to each other. At the fork back 2 There are an upper and a lower fork hook 4 respectively. 5 with which the fork is mounted in a height-adjustable fork carriage of a truck.

In the fork bend 3 the fork tine is reinforced in particular in that area which is adjacent to the bearing surface (eg roadway or shelf). This reinforcement serves as a wear volume to achieve the longest possible service life of the fork tine.

In the in the 3 and 4 illustrated fork invention is on the lower side of the fork bend 3 an exchangeable wear element 6 arranged. Here the wear element 6 in the front region V by means of a plug connection and in the rear region H by means of a screw connection 7 releasably attached to the fork tine.

in the Front area V (plug connection), the necessary tolerance compensation (before everything in the direction of travel).

For the screw connection 7 Expediently two laterally spaced screws are provided, of which at least one in a bore 8th of the wear element 6 is arranged and thereby the wear element 6 in the rear area H form-fitting leads laterally (see 4 ). The second screw may be in a transverse, laterally open slot 9 (Transverse slot) of the wear element 6 are as in 3 represented, in which case this screw is the wear element 6 only leads positively in the longitudinal direction.

A lateral guide of the wear element 6 in the front area is done by on both sides of the wear element 6 molded investment points 10 , which in the region of the plug connection in each case against a contact surface 11 abut the fork tine

To the two screws of the screw connection 7 To secure against loosening, the clamping length can be increased if necessary and / or the screw connection can be glued.
