OPW supported and unsupported boom type bottom loading arms are designed to provide flexible long range operation. A minimum of five swivel planes of rotation offer complete flexibility for loading or unloading of railcars and tank trucks or ISOTAINERS. These arms can be equipped with an API coupler, Dry-disconnect coupler, Threaded or Flanged connection or any other customer-specified end fitting to make connections at the side, at the rear or underneath the vehicle. Intermediate and end swivel assembly can be orientated upwards or downwards for optimum ease of operation.
To assist self-draining capability, optional low profile swivels may be selected in critical gravity unloading applications.
OPW bottom loading arms are available in many different configurations to accommodate specific customer requirements.
