Abstract
A remote-controlled mechanical locking chain gate has an electrically controlled winding mechanism with a locking device to keep the chain tight and prevent the chain from loosening when pressure is applied to the chain thus putting it into a locked position. The chain gate can be lowered or raised from a remote location using an accompanying remote control device. The motor and mechanics used to raise and lower the chain are modular for easy repair and replacement, and enclosed in a protective covering in order to protect them from damage or tampering. The motor can be operated by alternating current or direct current to provide the user with flexibility and allow the gate to be operated either by direct wire to an electrical source or by one or more batteries or recharging solar cells, and used in remote places where there is no access to electrical power.
