W740 Long Reach (Unsupported)

W740 Long Reach (Unsupported) Bottom Loading Arm

W740 long reach (unsupported) bottom loading arms for chemical and industrial products are ideal for loading/unloading tank trucks and rail cars. The long reach enables greater flexibility with miss-spotting or obstructions from other rail car and tank truck equipment. The W740’s long reach and significant miss-spot capabilities are due to a swivel boom that extends “unsupported” from the riser on the stand post. This provides an extra plane or rotation and allows the loading arm to track a distance along the bottom side of a rail car, or bottom side and rear of a tank truck.

W740 features a 2-plane Style-70 Outboard swivel joint with handle at the outboard end.

Outboard connections are typically dry-beak coupler, hammer union, cam and groove coupler or lap flange to suit the application. Breakaway couplings and purge systems can be incorporated as required
