Mini Electric Hoist is not a continuous duty type hoist and is only for instrument tent use. The details of which are explained below:
Here the rating of the motor is S3 20%-10min. This implies the following:
S3 is the maximum time in percentage per 10 min periods that the hoist can work at full load. For example S3 20%-10Min mentioned above implies that the hoist can be worked for 2mins for each 10min period over and over again(at full load).However, in case the load being lifted is less, then the time can be proportionately increased(full load with single cable is half the rated capacity). For example, for 50% load depending on capacity being used (i.e., single wire rope or double wire rope). The total time the equipment can be used in a 10min period is 4mins and so on.
