The electric hoist can now move left and right, but cannot move up. What is the problem? Fang Gong's explosion-proof electric hoist manufacturer will tell you about it. Since the design involves the issue of walking, it is important to pay attention to the issue of driving. Tell me in detail. Travel switches, also known as limit switches, can be installed on relatively stationary objects or moving objects. When an animal approaches a still life, the connecting rod of the switch drives the contact of the switch to cause the closed contact to break or the open contact to close. Control the movement of circuits and mechanisms by changing the opening and closing states of switch contacts.

　　Lifting machinery often uses limit switches to limit the limit position of its movement, causing it to stop moving before reaching the limit position to ensure lifting safety. But limit switches are installed under the electric hoist. When the hook rises to a certain position, the hook will collide with the limit switch, cutting off the forward power supply of the electric hoist and stopping it from lifting heavy objects, ensuring safety. But at this point, the reverse power supply of the electric hoist can be connected, so you can use a button to command the electric hoist to reverse (descend). After reversing, the fishing hook leaves the limit switch, and the limit switch is reset. At this time, the hoist can rotate forward again. So first, it is necessary to check whether the limit switch is reset. If there is a problem with the limit switch and it cannot be reset normally, then it cannot be raised. At this point, just repair and replace the limit switch. If there is no problem with the limit switch, check all other electrical appliances in the forward rotation circuit, and if the problem is found, it will definitely rise. I hope Ling Ying can provide some help in solving the problems for everyone.
