Abstract
This invention provides for a spring-balanced loading arm with a positive lock-down device use in a material handling system. It includes a swivel arm which is pivotally connected at one end to a support structure for swivel movement both in horizontal and vertical planes relative to the support structure. There is also provided an extendable lock-down device for positively locking the swivel arm. One end of the lock-down device is pivotally connected to the support structural and the other end is fixedly connected to the swivel arm. The lock-down device is adapted to be locked in position at several predetermined lengths. When the lock-down device is locked in a given position, it also positively locks the swivel arm and prevents any vertical movement of the loading arm.
