Abbruch von Industrieanlagen der Fa. Dierig in Augsburg. Demolition of industrial plants using an old Menck M250 crawler crane Dazu wurde ein Menck M250 Seilbagger mit einer 8to schweren Abbruchkugel eingesetzt
Good clean demolition, building completely soft stripped , no windows left in place , no doors hanging on , makes a rough hard job much easier when your loading hardcore away , your not spending ages picking the wagons for wood and glass , old school but the way I was taught and still the right way
Sehr schönes Video. Ich fühlte mich in die Zeit der 70er und 80er Jahre versetzt, als in Berlin Wedding eines der größten Sanierungsgebiete Deutschlands war. Birnenabbrüche der alten Mietskasernen waren an der Tagesordnung, was ich als Kind immer gern beobachtet habe. Das ist die Idealkombi: Ein Mann, ein Menk, eine Birne gegen ein Backsteinhaus - es verliert immer das Haus.
Carl Bolander & Sons, of St. Paul, Minnesota USA made sort of a niche career of using dragline-equipped cranes with both wrecking balls and the converted rippers from big bulldozers. Bolander operators would soften up the buildings, most of which had much rebar included, with the ball. They would then switch the lines to what an employee once referred to as “that thing.” (What he answered to a bystander’s question was, “That thing is really heavy!”) The ripper assembly had four custom welded up clevis & pin rigs for existing eyes on the left and right top and bottom of the rig. By that manner the (usually) four ripper teeth set into the rail would implant into the concrete and rebar debris after being dropped by the overhead line.
(To continue…) The ripper teeth being in the debris, the operator would utilize the dragline winch to haul the concrete away from the rebar, sort of comb out the steel (I-beams and pillars no trouble!), and make all nice and tidy, if you will… It was a great, very efficient, technique which their capable operators put to good use! It was also wonderful to watch!! Bolander would occasionally take down a steel reinforced cast concrete grain elevator Minneapolis was once the grain capital of the midwest USA) by use of a wrecking ball and two incredibly thick chains, overhead and dragline attached. The operator would lower the ball into the top opening of the concrete tubular structure until just the dragline chain hung out a bit. Then, by pulling in & out on the dragline, “saw” the tube with the chain, rebar hoops and all. Very fast and very efficient! And, again, fun to watch!!
Anyone ever think that the operator does not let the out swing go far enough before he starts the in swing? If he did, I think he would get a greater impact with the building?
By old style brickwork wrecking ball is a beast, not comparable with hydraulic shear. By ferroconcrete hydraulic excavators are better because often you have to cut steel reinforcement to pull down, and ball can't do this.
However I expect that hydraulic excavator with shears is much more expensive than crane with comparable reach. Question is, which system is more cost efficient in long term use.
Bella demolizione. Al tempo non si preoccupavano per la polvere. Grosse botte alla base finché veniva giù tutto. Anche la palla è più grande del solito.
Kann mir jemand sagen, welche Ecke das war? Am heutigen Dierig Areal oder ganz wo anders? Eberlestraße oder eher Deutschenbaurstraße Ludwigshafener Straße?
in realtion to concrete with steel, those brick building were unstable like playing card houses! would like to see this huge wrecking ball versus reeinforced concrete. what would be the weight of the ball; 5t, 8t? when you have a look at the videos where fa. luff uses smaller wrecking balls at same menck crane, in my opinion, the better choice. bigger is not always better
That would probably be 8 tonne. The length, reach, and height of the jib dictates what max weight of ball can be used. This was a short jib with low level hits, so allowing a heavier ball.
That had to be a very old building its a good thing they tore it down cause in a earth quake it would have been a death trap.It had no steel frame supports it crumbled like potatoe chips!!
It was a very strong build industrial plant. Brickwall about 75 cm with concrete and steel.Don't forget, the ball was 8to. An 8to ball can cut everything. When you put it on a normal roof it will go through straight to the basement.
