W840 PJ Long Reach Bottom Loading Arm

W840 PJ Steam Jacketed long reach bottom loading arms are ideal for industrial products that require minimal/no heat loss during transfer to tank trucks, rail cars and ISO container tanks, and where additional equipment is carried by the loading arm.

The W840-PJ’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 superior weight carrying capacity necessary for carrying steam jacketing and insulation. A two plane Outboard Style-70 swivel joint with a handle allows lightweight and simple coupling to the vehicle. Multiple tank connection formats available.
