Basic elements of the SLV – 70 system
The basic elements of the system are the frame and the platform which serve as the basis of the structure. The platforms are available in sizes from 0.74 m to 3.00 m . The steel frames are made of 48.3 pipe with a 2.7 mm wall . The steel grade is 235 JRH .
with yield strength Re min greater than 280 MPa, most often Re is approx. 280-285 MPa . Before the production process, each pipe section is sent to the Bydgoszcz Institute, which checks whether the certificate is compatible with the delivered batch pipes, in order to avoid “placing” false documents. The pipe is bottled on a machine designed specifically for JRH material, which shapes the pipe.
The machine has three production stages
in order to avoid stresses that could cause microcracks and pipe disqualification.
Additionally, reinforced star pins were used as part of the project. All semi-finished products that are used in the production of frames are welded on automatic welding machines – a guarantee of constant quality of welds.
The frames are manufactured on a two-station welding robot.
