W840 Long Reach (Supported)

W840 Long Reach (Supported) Bottom Loading Arm

W840 long reach (supported) 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/tank truck equipment. The W840’s long reach and significant miss-spot capabilities are due to a swivel boom that extends and is “supported” by the riser on the stand post. This provides an extra plane or rotation and allows the loading arm to support more outboard weight and track a larger distance along the bottom side of a rail car, or bottom side and rear of a tank truck.

W840 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
