Electric hoist product structure: The body is made of high-strength tensile shell or die-cast aluminum shell, and is precision manufactured using thin-walled extrusion molding technology, with small volume, light weight, and high strength. The standard chain electric hoist has an independent gearbox system, which seals the secondary coaxial transmission gear mechanism inside the gearbox, and adopts a long-life oil bath lubrication system. The powder metallurgy clutch of the electric hoist is used as an overload protection device, and the braking adopts a disc type DC electromagnetic field braking, which has high braking torque, stability, speed, and low noise.

　　What are the reasons for the inability to operate? Let me give you a detailed explanation of the accompanying solutions, hoping that everyone can be helpful.

　　Reason 1: The phase connection of the electrical primary line is incorrect, causing the phase protection function to activate and therefore unable to operate. Solution: Swap the power lines of the two phases to each other.

　　Reason 2: The fuse of the power supply is blown or the fuse switch is disconnected. Solution: Check if the current demand meets, replace the appropriate fuse or restart the fuse free switch.

　　Reason 3: The fuse of the control circuit is burnt out. Solution: Check and replace the accurate fuse.
