The electric outrigger is an independent small electromechanical system, which adopts the integrated design of reducer, T-shaped screw and motor. The specific features are as follows: 1. The electric outrigger can be connected to the main control box and can pass through the IP67 connector; 2. The free self-locking function of the T-screw itself eliminates all safety problems caused by the self-falling body. The electric outrigger itself has a high resolution, and the walking of the electric outrigger is only 0.01mm in one on-off operation, which can fully meet the requirements of various complicated working conditions. 3. Small, convenient and fast, and easy to maintain. 4. Multiple such electric outriggers can easily work together to ensure reliable and stable operation of the system. 5. Only the front end of the outrigger has a ball head design, which can cope with various complex ground conditions. 6. The static load is more than 3 times that of the dynamic load, which effectively reduces the influence of external forces on the system after it stops, and greatly increases the safety factor under static conditions. 7. Customized services can be provided according to customer requirements.
