Container and steel construction
TRUMPF nibblers and shears cut manholes into prefabricated containers. They can also cut the manholes prior to finishing the container. Pre-fabrication on a stationary machine can be eliminated in either procedure guaranteeing plenty of freedom on-site.
Making manholes for containers
Our shears and nibblers are perfect for making adjustments such as enlarging a cutout to fit. Cuts are burr-free and don't create sparks. Great flexibility in curves and low machine weight make it possible to cut even tight radii. Work preparation is a snap because tool-free sheet thickness adjustment is quick and easy with the height adjustment feature.
Thick sheet metal nibbler
For sheet thicknesses from 0.2 to 0.4 inches in mild steel, our thick sheet nibblers can be used. Nibbling is distortion-free, does not create sparks and requires minimal force.
After the hole is prepared, welding begins. The weld seams are oxide-free with a low roughness depth. The process is gentle on the material. And the high quality weld seam is of particular advantage because it does not require refinishing. Work is performed in a single step.
