The disclosure concerns a hanger device for suspending a pipeline, or the like. It includes a stationary housing adapted to be attached to a support. A rotatable roll is supported in the housing. Engageable teeth are supported by the roll and rotate therewith. A plate-thin lock is supported on the housing. The plate has a C-shape and the roll is positioned in the cutout of the C. The internal wall of the opening of the C is toothed at the top. The lock is shiftable with respect to the housing so that under the weight of the lock, the lock settles and the teeth of the lock mate with the roll teeth and prevent further rotation of the roll. The lock can be raised to separate the teeth, permitting the roll to be rotated. A hanger is windable on the roll, whereby winding of the roll adjusts the height of the object supported by the hanger. |
