7.2.8 Overload protection
The overload protection prevents hoisting motion when there is an excessive load. The operating point of overload
protection is stated in the written records for the test drive of the hoist. Overload protection is achieved by either a
mechanical switch or an electronic load sensor. The mechanical switch is connected to the hoisting circuitry, and
controls the hoisting contactor. The load sensor is connected to a separate condition-monitoring unit. The condition
monitoring unit prevents hoisting motion when there is an excessive load. The overload protectors with a load
sensor are equipped with an extra safety limit-switch.
Note: From year 2015, models with strain gauge do not contain a safety limit switch.
Overload device, mechanical switch, hoist frame size: VTs.
1. Rope anchorage
2. Lever mechanism
3. Set of plate springs
4. Mechanical limit switch
