Limit switch monitoring system
To prevent trouble caused by limit switch malfunctions during trolley traversing and/or boom hoisting, we have developed a limit switch monitoring system. This system consists of a PLC (Programmable Logic Controller) and additional one limit switch. The PLC continuously monitors the status of all limit switch pairs.If a fault is found, the PLC sends a stop signal to the controller and generates an alarm for the operator.

Anti-collision device
This device was developed to prevent a collision of mutual cranes by the infrared sensor, electromagnetic waves, supersonic waves or laser sensor.
