Differential speed controller, also known as anti fall device, is a safety protection device. When using, it is necessary to follow the rules of high hanging and low use. After wearing it, construction can be carried out, which not only does not affect the user's movement but also effectively protects the user's safety. In the event of a fall, it will quickly switch from a semi tense state to a locked state, because the user's movement speed will suddenly increase when falling, and the traction wire rope will be quickly pulled out. At this time, the pawl of the internal locking system will quickly bite the ratchet to complete the self-locking, and the user will stop descending instantly, completing the protective function. As the most protective device, safety performance is the only criterion for testing it. So what kind of anti fall device has the highest safety?

The safety of the differential speed controller is reflected in the following aspects. If all of these can be guaranteed, then its safety is guaranteed. Firstly, the information on the certificate of conformity should be clear and precise. High quality equipment with high safety must not be inferior. Equipment produced by legitimate manufacturers will not use rough craftsmanship or poor materials. If the information on the certificate of conformity is clear, the quality will be guaranteed. In order to protect the human body from the impact of falling, the anti fall device must have a buffer bag, which can cushion the impact force caused by the pulling of the steel wire rope during a fall, protecting the safety of the human body. The retraction of steel wire rope is very important for construction and fall prevention. A smooth and timely locking of the rope is a safe equipment.

A high-speed differential controller with high safety performance must be a high-quality equipment produced by a legitimate manufacturer, and it will not affect the user's movements. After a fall accident, it can be quickly locked and will not cause impact injuries to the human body.
