3 types of controls  
Manual control Remote control with a 6 m cable Radio control

Manual Control

   
It is the cheapest and the most basic system of control. It is not used anymore in western countries. The advantage of this system is the simplicity of the technology. However, it is the less convenient and less safe, specially when the operator is on the opposite side of the pouring or when he must operate the conveyor in front of the sun, a bright light or close to an obstacle (wall, roof, cables,…)
 

Remote Control with Cable (Pendent Type)

This control has a 6 m cable and is plugged into the electric control. It is the most commonly used system in Asia. It allows the operator to position himself a few meters from the truck to place precisely, safely and quickly the conveyor at the right position

  
         

Radio Control

This system is the most commonly used one in the world.  It is a highly secured and an efficient solution. Indeed, the operator can control the truck engine, the mixer and the conveyor from the radio control. It can also stand beside the workers who place the concrete. This system also protects the operator in case of contact with an electric cable.
