Improved system for operating telescopic load-bearing structures in general, for example telescopic arms tolerated by power-consuming machines such as crane trucks and similar and power-consuming machines comprising at least a telescopic structure equipped with a similar system

摘要

Linear mechanical multiple coaxial actuator system with synchronised movement for the deployment under load of a telescopic load-bearing structure, particularly of arms of crane trucks and similar. Power consuming machines or similar, such as cranes, crane trucks, mobile ladders, hoist platforms and other presenting at least the telescopic load bearing structure activated by the above mentioned system.
