Overload prevention device
The intelligence aided lifting equipment is provided with a weighing sensor (Fig. 1. 3). When
the weight to be lifted exceeds the set value or rated bearing capacity, lifting will stop and
“Overload Alarm” be displayed on the screen, in which the equipment can move downward only
(overload weight < 150% of bearing capacity).

Forced cooler
The intelligence aided lifting equipment is provided with a temperature sensor (Fig. 1. 4). It
is configured to detect the real-time temperature of braking resistor. In case that the detected
temperature is above 50 °C, the DC fan will produce forced air to cool the braking resistor. While
in the event that such temperature is above 100 °C, system operation will be suspended until the
temperature drops back to 80 °C. This device is applied only for 200 KG, 300 KG and 600 KG
types.
