Profile: B. I. Brooks & Sons, Inc. specializes in material handling systems. Our products include overhead conveyors, surface conveyors, hoists & trolleys, power rotators and lifts. We have designed overhead conveyor systems such as enclosed track conveyor for medium to light duty systems, 3", 4", & 6" chain & trolley I-beam systems, 3", 4", & 6" power & free systems, and inverted power only, or power & free systems. We also design and manufacture a variety of rotation devices that are used on overhead conveyor systems where parts are hung from a swivel fixture. The swivel fixture is a sprocket that engages the rotator chain causing the swivel to rotate at a constant speed.
