Automatic coupling mechanism for hose reels

摘要: A coupling mechanism for use in conjunction with a hose reel to automatically and selectively engage or disengage the motorized drive train. The utilizes sliding contact element on train which is arranged one of series cooperating stop lugs transmit driving power motor rotatable reel. When placed first position, it will be disengaged from lug allow rotate freely. shifted radially outwardly second lug, causing under motor. radial shifting between two positions can controlled by stopping at selected orientations. Also located within friction designed control through drag force movement when
