There are three operation modes: manual, wired remote control and wireless remote control; 2. The main elements of the electrical system and the hydraulic system adopt the world famous brand products, guaranteeing the reliability of the products. 3. There are two working modes to select: the floor frame and the shaft frame. 4. The slewing mechanism adopts three working modes: normally close brake, slow-motion (when distributing) and quick-motion (when transferring), which can prevent accidents due to the manmade misoperations during high-altitude operations. 5. The arm support adopts limit element analysis calculation, dynamic analysis calculation, wall-impingement tests and industrial reliability tests, together with tests and control of many technological processes so that the arm support system has steady operation, long service life and safety and reliability. 6. It adopts world cutting edge remote control and electrolyte proportional control so as to have comprehensive function and flexible operation; and the hydraulic impact and the reversing impact are small so that the reversing and the extending actions of the cloth arm are steady. 7. It is provided with multi-safety devices, with high security. 8. It adopts anti-wear steel pipe materials, with long service life and low use cost.
