Remark:


1. When the working voltage, temperature and humidity range you require exceeds the above table, please contact the authorized product agent for relevant information or customized chain hoist.


2. Intended use form: This hoist is designed for vertical lifting and lowering under normal atmospheric conditions and working environment.


3. The noise level standard is the value measured at a distance of one meter horizontally from the machine when the machine is operating normally.


■ Motor brake


" Electromagnetic power-off brake" is a unique brake design. Its special feature is that the brakes take effect immediately when the power is turned off, even under full load.


■ Hook and insurance piece


The hook is forged from high-tensile steel and heat-treated to meet strength and hardness requirements. The lower hook can rotate 360° horizontally and is equipped with a hook safety plate to ensure safety during takeoff and landing.


■ Phase protection relay


The circuit design of the phase protection relay can protect and avoid that when the phase of the motor power supply is connected incorrectly, the positive and negative movements of the motor will be inconsistent with the up and down movements, resulting in the limit protection switch being ineffective.


■ Limit switch


The upper and lower limit switches can automatically cut off the power when the limit is exceeded during lifting and lowering, preventing the chain from exceeding and ensuring safety.


■ Emergency stop switch (optional)


This button is used to stop the electric hoist in emergency situations. It's a red, mushroom-shaped button located at the top of the push button switch. When the button is pressed, power to the device will be cut off and the button will automatically lock. Turning clockwise releases the button and restarts the hoist.
