The LiftLok VRC safety system prevents lift operation by untrained or unauthorized personnel. A basic key switch or a more feature rich 10-key pushbutton digital keypad can be added to a mechanical or hydraulically operated Vertical Reciprocating Conveyor (VRC). Two keys are provided with the basic LiftLok keyed system while authorized lift operators can enter a unique 4-digit user/passcode, or swipe pre-programmed proximity credentials tag (key fob) on the LiftLok digital keypad to enable lift operation.
To simplify VRC installation with the feature-rich LiftLok keypad system, two administrative level programming codes are included for use by the installer. Once installed, authorized lift operators can be assigned a secure 4-digit user passcode to activate the call/send control station and operate the lift. Although access to the lift is typically assigned to only a few authorized personnel, up to 500 user passcodes can be programmed into the LiftLok keypad system. This ensures maximum user flexibility and long service life, since old user passcodes can be retired/deactivated and new codes assigned as responsibilities or personnel change.
