What is OPW Scissor Style Top Loading Arm used for?
OPW Scissor Style Top Loading Arm is used for top loading where vehicle spotting varies, especially tank-truck duties with reaches below 3,048 mm. Its configuration is selected around the loading geometry and transfer duty. AxFlow can help define the appropriate arrangement for a specific terminal.
How does OPW Scissor Style Top Loading Arm work?
The verified operating principle is that the secondary arm rotates 360 degrees in the horizontal plane and provides spotting allowance up to twice its length. This provides the movement or control needed at the loading point. Exact configuration depends on the installed piping and connection requirements.
What technical data should be checked for OPW Scissor Style Top Loading Arm?
OPW documents that the current StandardLine SCI is offered in 3 and 4 in sizes, with 5.5 bar working pressure and an operating range of -29°C to 60°C. These values provide a basis for screening the application. Final selection must also consider the actual medium, pressure, temperature and site geometry.
How do I choose the correct OPW Scissor Style Top Loading Arm configuration?
Check required reach, vehicle spotting tolerance, line size, loading valve arrangement, material and operating temperature. These parameters determine the suitable arm, material and connection arrangement. AxFlow can support product selection and availability checks.
Can AxFlow provide service and spare parts for OPW Scissor Style Top Loading Arm?
AxFlow can support service and spare-parts enquiries for OPW loading equipment. The correct parts depend on the installed configuration and revision. Supplying identification details helps confirm the appropriate components before ordering.
