Detailed Answer
A safety interlock is a linkage mechanism that prevents startup when operating conditions are not met. Hoist safety interlocks: lifting prohibited with the cage door open, operation prohibited with a landing door open, stop on limit trigger. As the control end, the remote control must be hard-wired to these interlock signals: when an interlock signal is open, remote commands are invalid. LIDEER and XINGJIA hoist-specific models both support interlock inputs.

Note:Bypassing a safety interlock is a serious violation; strictly forbidden.
