The new method for prevent hoist crane accident

 Hoist crane power is three-phase asynchronous cone brake motor,the motor operation efficiency and operation aspects,which is closely linked with the power supply.When the power supply phase sequence changes,motor operation direction and the original in the opposite direction,the limit bearing limiter does not work, which will leave a series of safety problems.
Through related requirement hoist crane should install protection device,but it’s very complex in current situation!the hoist crane protective system is not perfect!So What method can prevent hoist crane accident?
In order to avoid the happening of fault phase caused by lifting damage issue, we need to add electrical control system maintenance phase in hoist crane,when the power supply attack phase failure or fault phase, maintenance device can quickly cut off the power to ensure the safe and reliable operation of the crane.you know that xinxinag hundred percent electrical and mechanical co.,ltd can solve this problem, in themeanwhile,  it can produce Transfer Trolley With Hydraulic Lifting Table and contain perfect After -sale service.
