ABSTRACT:
A metal melting installation in which a movable carrier has a kiln door fixed at its front end for closing an entrance opening of the kiln and a crucible provided forwardly of the door so as to lodge in the kiln when the entrance opening is closed. A drive means for closing the carrier comprises: an electric motor in a control circuit that also includes a limit switch mounted adjacent the kiln entrance opening; a chain and sprocket gear for moving the carrier; a damper device interconnecting the drive shaft of the motor and one sprocket wheel of the gear for allowing it to keep on rotating to dissipate accumulated momentum energy when the motor is de-energized, a push button being provided on the carrier for contacting the limit switch to thus cut off the electric circuit and deenergize the motor when the door on the carrier closes the kiln opening.
