Why don other manufacturers recommend the use of bed limiters and bed hold-downs?
They take the position that the beds will perform properly under normal conditions and they do not wish to jeopardize their bids with the addition of an unspecified device. Koch-Glitsch, on the other hand, feels that restraining devices are worthwhile, and that we have the responsibility to advise the customer strongly about these safety devices. They are extremely economical in comparison to the damage that might occur as a result of an operating upset.
