A deviation type hood is a specialized hood designed specifically for conveyors equipped with deviation switches or centering rollers. As the width of the adjustable centering rollers of the deviation switch exceeds the width in the middle of the conveyor, standard size hoods cannot wrap the deviation switch and centering rollers inside. Moreover, when the belt deviation triggers the deviation switch to stop, the deviation switch needs to be checked and reset. Therefore, deviation switch boxes are paired on both sides of the hood, known as the deviation type hood. The materials for the deviation type hood can be selected: galvanized steel plate, color coated steel plate, stainless steel plate, aluminum magnesium manganese plate, fiberglass steel plate, PC endurance plate, etc. Different materials will be used in different working conditions, and can be selected according to the customer's on-site environment and needs. The deviation switch box of the deviation type hood has standard dimensions, and different sizes can be designed according to the customer's on-site environment and needs. The deviation type hood is only installed in positions with deviation switches or centering rollers, and the quantity is configured according to the customer's on-site demand.
