We make the machine in one unit, like the shutter door machine, the roof panel machine, it is the Cantilever control box. You do not need to worry to connect all of the cables, only to connect the main motor cables. All of the rest cables are connected by the air plugs, and We made the marks on the air plugs A to A and B to B. Also regarding to the hydraulic station, you do not need to take off the oil pipes, all connected and packed, and We put the hydraulic station and the control box inside the machine. You just put the start button, then it can work. If the hydraulic station is large, it needs to be put outside, then We will offer you the hydraulic station pipes drawings. Also We will offer you the full set of the cable drawings for you to check if there is any problems.
