Mini electric hoist to meet industrial production requirements

With electric wire rope hoist  performance and increasing the mechanical properties of hard, speed range, speed and high precision, good stability, easy to control and energy-saving features, can well meet the lifting equipment safe and stable, reliable, good and reliable operability , maintenance and other requirements, mini electric hoist has been widely used in industry.
Currently, many electric hoist brands, can fully meet the needs of lifting products industry characteristics are not many, the main difficulty is due to the particularity of the crane, mini electric manual hoist  must have some special properties.
Fast dynamic response, in order to meet the changing needs of the crane load dramatic, ability to control a wide range of speeds, at low speeds can cause the motor around 2 to 3 times the rated output torque of the output peak torque load can withstand dramatic changes due to the potential energy the impact of current occurs, and ensure continuous and reliable operation of mechanical vibration environment, the deceleration of the motor can be reliably released renewable energy, the current capacity of the brake unit as the need for greater, with high reliability protection system,wire rope winch since the l organizations are required to pay special attention to mechanical brake is released before or after the moment of brake to prevent the "slip hook" of the control; possess powerful monitoring system, through the monitoring of implementation of various parameters of the system failure alarm and failure analysis.
