Abstract

The implement is especially suitable for lifting manhole covers in which the intermediate space between frame and cover is badly soiled or corroded. Owing to the fact that the implement puts the manhole cover under tension by means of the helical springs due to the tightening and thus produces a high tensile stress, a few hammer blows to the manhole cover are sufficient and it jumps out. I have already built and tested the implement and it functions perfectly. The advantage of the implement consists in the fact that: 1) one man can get the manhole cover out without effort, where otherwise two workers were required, and 2) work can be carried out in a substantially more cost-effective and time-saving manner. <IMAGE>

Description

Der Zweck des Gerätes besteht darin,durch Staub,Rost oder sonstigen Schmutz festgesetzte Kanaldeckel mühelos herauszuheben.The purpose of the device is through dust, rust or other dirt stuck manhole covers to lift out effortlessly.

Das Gerät (Abb. 1+2) wird über den Kanaldeckel (Abb. 3) gefahren. Die Haken (B) werden in die Löcher (M-Abb. 3) an zwei Seiten des Kanaldeckels hineingesteckt und dann werden die Hebel (D) nach unten gedrückt.The device ( Fig. 1 + 2) is moved over the manhole cover ( Fig. 3). The hooks (B) are inserted into the holes (M- Fig. 3) on two sides of the manhole cover and then the levers (D) are pressed down.

Durch die Federn (A) setzt man die Haken (B) die in den Löchern des Kanaldeckels stecken auf Zugkraft. Je nach Erfordernis arretiert man den Splint (H) in eines der Löcher (F). Danach schlägt man mit dem Hammer auf den Kanaldeckel der dann durch die Zugkraft herausspringt. Man kann dann das Gerät mit dem Kanal­ deckel zur Seite schieben wofür die Räder E und I montiert sind.The springs (A) are used to place the hooks (B) in the Holes in the manhole cover are trapped. Depending on the requirements, the split pin (H) is locked in one of the holes (F). Then you hit with the Hammer on the manhole cover which then pulls through pops out. You can then use the device with the channel Push the lid aside for what the wheels E and I are mounted.
