Product features
Founded in 1979, Rotar is a professional excavator accessory manufacturer, and its main products include olecranon shears, steel grab, hydraulic hammer and other engineering excavator accessories. In 2022, Henan Wanguo Science & Technology Co., Ltd. successfully signed the agency of Lotta Company in China, responsible for the sales and comprehensive after-sales service in Chinese mainland market.
1. Replaceable cutter head
RSS series is equipped with replaceable scissors, and the core parts such as oil cylinder are completely closed to protect the core parts of the equipment. The design of cutting mouth ensures that scrap steel is forced to go deep into the cutting mouth, and the cutting effect is improved. RSS series fuselage is made of special high-performance steel and wear-resistant materials, which is very strong.
2. Rotating device and rotating support
RSS series has powerful rotating device and heavy-duty double-row rotating support. The hydraulic motor and gear box in the device can generate high torque, which makes the RSS series move.
3. Special hydraulic cylinder
The hydraulic cylinder with integrated speed-increasing valve developed by Rota Rotar can quickly close the shear, and RSS can switch from speed mode to power mode when the operation requires greater shear force.
4. Double hose connector
The double hose connection and large diameter hose, oil hole and pipeline on the rotary joint can achieve the best hydraulic oil flow. This connection can avoid hydraulic system.
