Abstract
Description
Die Erfindung betrifft ein Lastaufnahmemittel zum Transportieren schwerer Lasten; mit wenigstens zwei Schenkeln; wobei jeder Schenkel einen Tragholm umfasst, welcher im unteren Abschnitt eine die Last aufnehmende Pratze aufweist.The The invention relates to a load handling device for transporting heavy loads loads; with at least two thighs; with each leg one Support beam comprises, which in the lower portion a load-receiving Claw has.
Für den sicheren
Transport schwerer Lasten wie Coils, Bandringe, Blechpakete, Brammen,
Walzen, Papierrollen oder dergleichen bedient man sich in der Praxis
speziell ausgebildeter, mit einem Kran verbindbarer, Lastaufnahmemittel.
Diese weisen gemeinhin zwei Schenkel auf, wobei die Schenkel einen Tragholm
mit daran starr oder klappbar ausgebildeten Stahlpratzen umfassen,
welche die Last unterfassen. Derartige Lastaufnahmemittel sind beispielsweise
aus der
Bis zum heutigen Tage erfolgt die Aufnahme schwerer Lasten jedoch mehr oder minder stoßartig, wobei ein Stoß um so kräftiger ausfällt, je höher die Anfangsgeschwindigkeit ist, mit der das an einem Kran hängende Lastaufnahmemittel an die Last gefahren wird. Dabei können insb. die Stahlpratzen des Lastaufnahmemittels beim Anstoßen an die Last innere und/oder äußere Lagen der Last derart nachhaltig schädigen, dass diese für eine Weiterverarbeitung unbrauchbar werden.To Today, however, heavy loads are being absorbed or less jerky, with a push around so stronger fails, The higher the initial speed is that of the lifting device hanging on a crane is driven to the load. In particular, the steel claws the load receiving means when abutting the load inner and / or outer layers damage the load so sustainably, that this for a further processing become unusable.
Zur Verminderung derartig kostentreibender Schäden ist bereits bekannt, den das Lastaufnahmemittel hebenden Kran mit einem Frequenzumrichter auszustatten, welcher es ermöglicht, stufenlos Drehzahlen bis zur Nenndrehzahl einzustellen. Die Heftigkeit eines Stoßes bei Lastaufnahme hängt dann einzig und allein vom Geschickt des Kranführers ab, wobei in der Praxis schonende Lastaufnahmen bei immer knapper bemessen Arbeitsabläufen eher die Ausnahme als die Regel sein dürften.to Reduction of such cost-driving damage is already known, the equip the lifting device lifting crane with a frequency converter, which makes it possible infinitely variable to set speeds up to the rated speed. The violence a push hangs when lifting the load then solely on the skill of the crane operator from, in practice gentle load pick-ups with increasingly tight work processes rather the exception should be the rule.
Dies sucht die Erfindung zu vermeiden. Ihr liegt die Aufgabe zugrunde, ein gegenüber dem Stand der Technik verbessertes Lastaufnahmemittel zum Transportieren schwerer Lasten bereitzustellen, welches eine schonende Lastaufnahme, insbesondere unabhängig von einer Anfangsgeschwindigkeit eines Krans, garantiert.This seeks to avoid the invention. Its the task one opposite the prior art improved load-carrying means for transporting provide heavy loads, which is a gentle load, especially independent from an initial speed of a crane, guaranteed.
Diese Aufgabe wird durch ein Lastaufnahmemittel zum Transportieren schwerer Lasten gemäß den Merkmalen des unabhängigen Patentanspruchs 1 gelöst. Vorteilhafte Aus- und Weiterbildungen, welche einzeln oder in Kombination miteinander eingesetzt werden können, sind Gegenstand der abhängigen Ansprüche.These Task is made difficult by a load handling device for transporting Loads according to the characteristics of the independent Patent claim 1 solved. Advantageous training and further education, which individually or in combination can be used together are the subject of the dependent Claims.
Das erfindungsgemäße Lastaufnahmemittel zum Transportieren schwerer Lasten wie Coils, Bandringe, Blechpakete, Brammen, Walzen, Papierrollen oder dergleichen baut auf gattungsgemäßen Lastaufnahmemitteln dadurch auf, dass der Tragholm zweigeteilt ausgebildet ist, wobei zwischen oberem und unterem Teil des Tragholms wenigsten ein Dämpfungselement angeordnet ist.The Lifting device according to the invention for Transporting heavy loads such as coils, band rings, laminated cores, Slabs, rolls, paper rolls or the like builds on generic load-carrying means Characterized in that the carrier spar is formed in two parts, wherein between the upper and lower part of the supporting spar at least one damping element is arranged.
Erfindungsgemäß bevorzugt ist der untere Teil des Tragholms gegenüber dem oberen Teil des Tragholms vertikal führbar ausgebildet, wobei vorzugsweise am oberen Teil des Tragholms wenigstens ein Führungselement für eine an dem unteren Teil des Tragholms angeordneten Vertikalführung ausgebildet ist oder umgekehrt.According to the invention preferred is the lower part of the supporting beam opposite the upper part of the supporting beam vertically routable formed, preferably at the upper part of the support beam at least one guide element for one formed on the lower part of the support beam arranged vertical guide is or vice versa.
Ausgehend
von der
Die Erfindung vermindert vorteilhaft selbst bei stoßartigen Lastaufnahmen durch Lastaufnahmemittel hervorgerufene Abdrücke in einer Last.The Invention advantageously reduces even with jerky load pickups Load-bearing means produced impressions in a load.
Zusätzliche Einzelheiten und weitere Vorteile der Erfindung werden nachfolgend beispielhaft an Hand einer sogenannten Teleskop-Coilzange, auf welche die vorliegende Erfindung jedoch nicht beschränkt ist, und in Verbindung mit der beigefügten Zeichnung beschrieben.additional Details and further advantages of the invention are given below by way of example with reference to a so-called telescopic coil tongs, to which however, the present invention is not limited, and in connection with the attached drawing described.
