W340 Long Reach (Unsupported)

W340 Long Reach (Unsupported) Top Loading Arm

W340 long reach top loading arms for chemical/Industrial products are ideal for loading/unloading multi compartment tank trucks without having to move the vehicle, or for where significant miss-spotting is likely, i.e. when connecting with a line of coupled rail car tanks. The W340’s longer reach and significant miss-spot capabilities are due to a “swivel boom” that extends “unsupported” from the riser on to which a fixed reach loading arm is attached. This provides an extra plane or rotation and allows the loading arm to “track” a considerable distance along the centerline of the tank truck, rail car or ISO tank container.

Sizes in 2”, 3”, 4” and 6”.

Materials of construction: Carbon steels, aluminum, 304L, 316L and 904L stainless steel. Exotic alloys, Duplex Stainless Steel, Super Duplex Stainless Steel, Alloy 20, Monel, Inconel and more.

Dual race Split Flange WL2 or Single race WSS swivel joints

Seals in Viton™, Nitrile, EPDM, PTFE, Kalrez™ etc. to suit the application

Compression spring, counterweight, pneumatic or hydraulic balance control systems

Available in Left Hand or Right Hand, Up-feed or Down-feed and Side-feed configurations, all mounted on a stand post

Typical range of vertical movement is +70° park position to -20° load position.
Typical “boom” length is 1,500mm, and typical range of primary length is 2,000mm to 2,300mm with a 1,500mm drop tube. All dimensions can be changed to suit each application.

Alternative drop tube arrangements are available for unloading and closed loop applications.
