Long Range Top Loading Arm Unsupported Boom Model 2239-UB

The long range top loading arm unsupported boom is commonly used in applications where there is no existing steel work for support. There will be an increased load, therefore a heavy-duty base swivel joint is incorporated to provide support. The horizontal boom provides a wide range of operation which allows for multiple compartments to be filled without having to reposition vehicles used in loading arm filling processes. Similar in its design to the model 621 – LR/B, this arm has four swivel joints to allow for easy manoeuvrability.

Furthermore, this top loading arm includes a compression cylinder for ease of movement and a loading valve for either a hold-open or stay-open operation, extension/remote control for outboard loading valve operation. It is also fitted with a vacuum breaker to allow for a faster drainage. This arm can be manufactured in right or left hand configuration.
