W440 PT Long Reach Top Loading Arm

W440-PT Electrical Heat Traced long reach top loading arms are ideal for industrial products that require minimal/no heat loss during transfer to tank trucks and rail cars, and where significant miss-spotting is likely and additional equipment is carried by the loading arm.

The W440-PT’s longer reach and significant miss-spot capabilities are due to a “supported swivel boom” that extends from the riser on the stand post and to which a fixed reach loading arm is attached. The supported boom allows for even longer range and/or superior weight carrying capacity necessary for carrying heat tracing and insulation. The supported boom provides an extra plane of rotation and allows the loading arm to “track” a considerable distance along the centerline of the tank truck, rail car or ISO tank container. Multiple drop pipe options available. Electrical heat tracing to EX zoning specifications where required
