Abstract

On each side of the truck is a four bar chain linkage with coupling link (1) and stabilising link (3). Connected to the ends of links (1) and (3) are the forks (2). A hydraulic cylinder (4) with a protected piston rod drives onto the crank (5) to produce an approximately straight line vertical movement of the forks. The truck has an extendable stern piece allowing heavier loads to be lifted. ADVANTAGE - Provides high visibility of forks for the driver.

Description

Der Hebelgetriebemechanismus (Schema siehe Fig. 1) besteht aus Kurbeln a und c (die versch. Indices geben versch. Lagen an) und Koppelstange (d, e, f). Die Indices bedeuten dabei folgendes: 1 gibt die höchste Lage des Anlenkpunktes der Koppelstange, 2 die tiefste Lage des Anlenkpunktes an. Wegen der Abweichung von der Geraden ergibt sich die maximale Höhe zu h falls man die Koppelstange ohne die Verlängerung f betrachtet, zu h (max) mit der Verlängerung f.The lever gear mechanism (scheme see Fig. 1) consists of cranks a and c (the different indices indicate different positions) and coupling rod (d, e, f). The indices mean the following: 1 indicates the highest position of the articulation point of the coupling rod, 2 the lowest position of the articulation point. Because of the deviation from the straight line, the maximum height is too h if you consider the coupling rod without the extension f, too h (max) with the extension f.

Vorteile zu bisherigen Gabelstaplern:
Das Hubgerüst ausgeführt als Gelenkgetriebe ermöglicht dem Fahrer freie Sicht auf die Gabelspitzen in jeder Lage des Hubgerüsts was das Einfahren in den Stapel sehr erleichtert.Advantages over previous forklifts:
The mast, designed as an articulated gearbox, gives the driver a clear view of the fork tips in every position of the mast, which makes entry into the stack much easier.

Beschreibung zu Fig. 2:
Die Koppelstangen 1 und 3 tragen die Gabeln 2 welche über den Hubzylinder 4 und die Kurbel 5 bewegt werden.Description of Fig. 2:
The coupling rods 1 and 3 carry the forks 2 which are moved via the lifting cylinder 4 and the crank 5 .

Gapelstapler-VerbesserungenForklift improvements

Neues Hubgerät
Neues Hubgerät dadurch gekennzeichnet, daß die Hubvorrichtung als Gelenkgetriebe ausgeführt wird.
Vorteil: Freie Sicht auf die Ladung.New lifting device
New lifting device characterized in that the lifting device is designed as an articulated gear.
Advantage: A clear view of the load.

Ausfahrbares Heck
Neues Gabelstapler-Heck dadurch gekennzeichnet, daß der notwendige Manövrierraum durch das Einziehen des Hecks verkleinert wird.
Ausfahren des Hecks während des Hebevorgangs: Die Hebeleistung des Staplers wird vergrößert.Extendable rear
New forklift rear characterized in that the necessary maneuvering space is reduced by retracting the rear.
Extending the tail during the lifting process: The lifting capacity of the truck is increased.

Neue Transportstellung
Während des Transportierens von Waren d. h. während des Fahrens befindet sich die Ladung über den Vorderrädern d. h. die Leistung des Staplers wird bei gleichem Gewicht erhöht.New transport position
During the transport of goods, ie while driving, the load is above the front wheels, ie the performance of the truck is increased with the same weight.

Einfahrhilfe in den Stapel
Vor dem Einfahren des Staplers unter die Last stellt die Einfahrhilfe die Höhe der Gabeln ein, so daß es nicht zu einem Zusammenstoß mit dem Stapel kommen kann. Dies erleichtert die Arbeit da man manchmal die Gabelspitzen nicht mehr sehen kann. Dies geschieht über automat. Abstandswarngeräte, die an den Gabeln befestigt sind und über eine logische Schaltung an die Hub- bzw. Kippvorrichtung gekoppelt sind.Entry aid into the stack
Before the truck is moved under the load, the drive-in aid adjusts the height of the forks so that there is no collision with the stack. This makes the job easier because sometimes you can no longer see the fork tips. This happens via automat. Distance warning devices that are attached to the forks and are coupled to the lifting or tilting device via a logic circuit.

Gabelverschiebe-Vorrichtung
Diese leichtgängige und mit einer Hand zu bedienende Gabelverschiebevorrichtung besteht aus einem Gelenkgetriebe an dessem Anlenkpunkt eine horizontale Geradführung ausgeführt wird.Fork shifting device
This smooth-running fork shifting device, which can be operated with one hand, consists of an articulated gearbox at the articulation point of which a horizontal straight guidance is carried out.
