This application deals with a device for loading fluids such as oil into tank cars. It has an inboard and an outboard conduit pipe which are pivotally connected together. The inboard pipe connects with a supply strand pipe and the free end of the outboard conduit has a nozzle that connects with the tank car to be loaded. The invention is concerned with a balancing means for balancing the inboard and the outboard conduit members and includes a balancing spring in combination with an articulated linkage that splits the balancing force of the balancing spring between the inboard and the outboard conduits to balance both of them so that a user of the device can manipulate the nozzle on the free end of the outboard conduit member as if it is substantially weightless.
