The limit switch in the elevator is also called a travel switch, which is a device that limits the movement of the limit position and protects the switch from damage. Installation principle: The limit switch of the cargo elevator should ensure that the cargo elevator platform runs at full load and lower limit. After the switch hits the block, the control power is automatically cut off and after stopping, the lower limit installation position should limit the ground distance of the buffer spring under the platform to 300-400 mm, and the limit switch action should be guaranteed at the installation position of the limit switch. The rear acting and transmission platform cannot hit the buffer spring.
In order to ensure the distance between the upper and lower limits and the upper limit, the limit switch and the upper and lower limits between the distances should be guaranteed to be at a contact distance of 0.2-2mm when the limit switch is turned off. When adjusting the limit switch and limit switch , Can be installed on the rail frame and accessory frame and cable guide frame.
Note: To change the adjustment of the wire rope, the round head bolts should be screwed in first, and the moving nuts should be applied with the bolts to avoid excessive moving nuts and damaging other parts.
After replacing the elevator platform safety wire rope, the lever position should be adjusted to reach the upper limit.
The limit switches on the elevator platform should be checked regularly, and once damaged, they should be replaced or repaired.
