EXTREMELY CRAMPED RATIOS WHEN ERECTING BERLIN SHORING IN BERLIN-PANKOW
New residential buildings were constructed on Prenzlauer Promenade in Berlin. The excavation pit was secured with Berlin-style shoring, which had to be removed by the customer after the residential buildings were completed in autumn 2020. In this case, the removal of the H-beams and the associated transport were particularly tricky. There was only a small access road where the large excavator could not turn. Accordingly, it could not turn around with the beams and could not load them onto the waiting truck. Added to this was the danger posed by the HEB 400 beams, which are over 10 metres in length, if they were to swing out of control. The initial plan was therefore to cut the beams by burning them and then shorten them accordingly. However, thanks to MÜLLER Machinery, a much more sustainable and economical solution was found.
This challenging task was successfully completed using the MÜLLER MS-6 HFB SG without cutting the beams. The compact and lightweight MÜLLER excavator-mounted vibratory hammers can be mounted on all common excavators. The power supply is provided by the board hydraulic system and the control is via the operating levers of the excavator. The side gripper is particularly advantageous at cramped ratios. It must not be put on profiles from on top, but seizes them laterally and fixes them at the same time. A swinging of the pile driving or pulling material is excluded with that.
On the site on Prenzlauer Promenade, the side grab was able to grip the H-beams on the side, pull them out of the ground and then place them between the excavator's chains. The excavator pushed the beams through to the back, where they were absorbed by another excavator and loaded onto a truck.
