Energy chain device with at least one drive device for long travel paths
An energy chain device includes at least one energy chain for guiding lines, cables, hoses or the like between a fixed and a movable connection region so as to form a curved region between a moved strand and a stationary strand. Each energy chain has a number of links which are connected to one another in a flexible manner and are formed by link plates which are arranged parallel to one another and transverse webs which connect the link plates. The energy chain device further includes at least one drive device which is operatively connected to the moved strand, and a control unit which is connected to the drive device so as to transmit signals and is connectable so as to transmit signals to a control device of a device which is connectable to the movable connection region.
1. An energy chain device, comprising:
at least one energy chain for guiding lines, cables, or hoses between a fixed and a movable connection region so as to form a curved region between a movable strand and a stationary strand, each energy chain having a number of links which are connected to one another flexibly and are formed by link plates which are arranged parallel to one another and transverse webs which connect said link plates,
at least one drive device which is operatively connected to the movable strand, and
a control unit which is connected to the drive device so as to transmit signals and is connectable so as to transmit signals to a control device of a device which is connectable to the movable connection region;
wherein several drive devices which are spaced apart from one another are arranged along a travel path of the movable strand.
