Abstract: A selectively extendable chute assembly includes a fabric chute covering member having a plurality of extender tubes secured thereto. A coil spring is secured inside each extender tube to continuously urge the extender tube into a retracted position. Pressurized fluid is selectively provided to the extender tubes to urge them into an extended position whereby the chute becomes usable for unloading a vehicle or another type of storage facility.
