Due to the aging process of the fringes installed in the port, it is necessary to check these at regular intervals and to renew them if necessary.
In order to replace the existing old friction materials, these are dismantled and measured. Depending on the degree of damage, the shots are also repaired or renewed. After the production of the new friction – with a weight of up to 900 kg – they were placed on the spot and positioned with lifting devices on the dough and fixed and secured by means of bores in the receptacles with new connecting pins.
