Electric hoist apparatus and its role in the six


  Wire rope hoist six major installations and the role each user should be aware that even with a timely response to resolve minor problems arising in the process, to ensure safety and efficiency.
      An electromagnetic brake: electric hoist brake is a unique design, which feature full load even when the power supply is suddenly cut off, the brake immediately play a role.
      2, the mechanical load brake: mechanical load brake at full load does not result in a fall faster and faster, and is independent of the motor brake, the brake even when the motor stalled, the role of mechanical load brake still makes a slow load speed slowly declining.
      3, hook and safety Tongue: hook is forged from high tensile steel and heat treated to meet the strength requirements, the next level of the hook can be rotated degrees, and with a hook in order to ensure safety tongue rose the security.
      4, reverse phase protection: circuit design ensures that when the motor power phases and to avoid wrong connection, do not cause  rope hoist  motor burned.
      5, the limit switch: When the hoist up and down to the limit switch will be off automatically.
      6, the emergency stop switch: When the button is pressed, the power supply will be cut off, and the button to automatically lock and turn it clockwise the button can be released and can be restarted electric hoist.
