When the unbalance detector is electrically connected to the alarm indicator, once the unbalance detector acquires the unbalance signal of the balance beam device 1, the alarm indicator sends out sound, light and other signals under the action of the unbalance signal to remind an operator that the balance beam device 1 is in an unbalance state.
When the unbalance detector is electrically connected to the enabling circuit of the hoist, once the unbalance detector obtains the unbalance signal of the balance beam device 1, the enabling circuit may adjust and restore the balance state of the balance beam device 1 by controlling the operation parameters of the hoist, and of course, the restoration of the balance state of the balance beam device 1 is actually to restore the balance of the first and second ropings 2 and 3 in the operation state.
On the basis of any one of the above embodiments, the utility model also provides a winch, which comprises the winch rope winding system; the winding system of the winch is a redundant system.
