What is the hook travel limiter
Hook Stroke limiter is a device that limits the travel of the hook to prevent accidents. Today I will introduce to you what the working method and scrapping conditions of the hook stroke limiter used for a small car variable-amplifier horizontal arm boom jack. Let's learn about it together.
Its working method is: when lifting a heavy object, the reel rotates, and the pins on the end plate of the reel flange force the star wheel to rotate accordingly. The star wheel further drives the screw to rotate, and the nuts installed on the screw move along the screw toward the end switch position. When the hook is raised to the limit position, the screw presses the push rod of the end switch, disconnects the contacts of the switch, causing the lifting mechanism to power off and stops the hook to stop.
If the hook stroke limiter switch fails or the contact wear exceeds the standard and cannot be reliably powered off, it should be scrapped. Through the appeal introduction, we can see that the working mode and scrapping conditions of the hook stroke limiter are very strict, which is to ensure our personal safety and equipment safety.
