Only for crane with two trolleys
Notes on installing the second trolley:
─ Where and in which direction the second trolley is installed is specified in the planning documents.
─ The trolleys are labelled “Trolley I” and “Trolley II” for clear assignment.
─ Installation of the second trolley and trolley power supply is identical to the first trolley. The following diagram illustrates how the trolley power supply is routed.

─ A crane with two trolleys has two profile rails. The upper one for both energy chains, the lower one for cable guidance.
─ Both trolleys have their own separate energy chain for trolley power supply. One runs from the trolley to the left, the other to the right.
─ Both energy chains start in the upper profile rail exactly in the middle on the main girder. One runs clockwise from there through the profile rail to the trolley, the other anti-clockwise.
─ Both energy chains merge into the connection cables in the middle of the main girder. The connection cables run in the lower profile rail to the panel.
