1)structures completely made using wearproof and abrasionproof steel with high elasticity to withstand the cylinder energy;
2)cylinders completely protected by the carcass or by specific carters, avoiding possible collisions between stem and rods.
3)fast valve. An integrated system permits a big reduction of the hydraulic cylinder opening and closing times, increasing the equipment productivity.
4)on every OSA equipment there is an hydraulic system which preserves the cylinder and all the hydraulic parts from possible pressure peaks;
5)the rotation system has an hydraulic valve that makes the rotation gearmotor automatic clutching, preserving the whole system.
6)an attentive design and an experience of many years give OSA demolition equipment s.r.l the possibility to make equipment with a small weight and with big openings;
7)an advanced design and big cylinders permit to obtain big cutting forces;
8)movable and interchangeable blades on four sides;
9)there is no pressure fall in the hydraulic system;
10)thanks to many inspection doors, maintenance is very easy and safe.
