The LCG312C intelligent integrated vehicle-mounted arch frame trolley is a device that integrates steel arch frame installation, welding mesh and connecting ribs, and excavation surface measurement. The equipment adopts a vehicle chassis to meet the needs of flexible movement, transition and emergency of the equipment, and can complete the work reliably and efficiently in any occasion. All three booms can be operated remotely, and the left and right booms can be manually controlled in the hanging basket, which can reduce labor costs, mitigate construction risks, improve efficiency, and achieve standardization and factoryization of tunnel vertical arches.
