1.Salient features
①. 150% rated torque / 0Hz (FVC),the crane operates stably when starting, hoist and fall.
②. Encoder feedback provides further protection: the load is hold in the air or going down slowly in case of brake failure or over speed, without slip.
③. Unique brake control logic prolongs the service life of the brake system, and enhances the operation safety.
④. Strong adaptability of power grid, high torque output remains when under voltage.
⑤. Flexible and efficient operation: Light load at high speed and heavy load at low speed.
