Interlock Operation System

The dock shelter can be positioned perfectly using the control buttons on the control box. For the WI-Series 2 different control boxes are available depending on the number of dock products that need to be controlled.

There are several advanced control options which provide additional functions such as door control, leveller control, automated interlock to prevent operation when the dock door is not fully open, and automatic door closure locking until the leveller has been parked correctly.
