The Descent Control Device (DCD) enhances the safety and reliability of the LOCKERBASKET® System by automatically arresting a falling basket in the event the operator loses control of the hoisting chain or a malfunction in the equipment occurs. It is easily installed in new or existing changerooms. It comes with a factory attached steel coupler designed to assist in the proper installation and prevent unintentional removal after installation. The dual braking system minimizes ratcheting that occurs in some descent control devices through dissipation of energy in the secondary friction brake system after the primary brake has been activated. The locking mechanism will not activate when the basket is ssafely lowered. Should the locking mechanism engage, it will remain locked until the tension on the device is relieved by the operator. The DCD is also calibrated to allow an empty basket ot be lowered to proper operating heights.
