Working principle of speed difference automatic controller

The speed difference automatic controller, also known as the speed difference fall arrester, is used for the staff to climb the height to avoid accidental fall. Even if there is an accidental fall, it can quickly and reasonably ensure the safety of the staff, and can quickly brake the system within the limited distance to lock the falling staff and maintain the personal safety of the staff. The sealed aluminum casing anti falling safety device causes automatic control due to the change of speed; According to the anti ratchet double disc brake system, the body can not be controlled to fall under reasonable control; When working, you can pull out the rope at will. When everything is normal (less than two meters per second), it will not endanger all normal work; Specifications and models are 3M, 5m, 7m, 10m, 15m, 20m, 30m, 40m and 50m in length.

The speed difference automatic controller is fixed and suspended above the operation point. The rope in the automatic controller is connected with the upper half ring of the safety belt. The rope can be pulled out arbitrarily and operated at a certain position. After the work is completed, when the person moves upward, the rope will automatically retract into the automatic controller. In case of falling, the automatic controller will brake and control under the influence of speed. During the test, the length of the pull-out rope is 0.8m, and it is required that the falling distance of the simulated human body should not exceed 1.2m.

The suspension point within the radius does not need to be replaced. During normal use, the safety rope will stretch freely with the human body. Under the action of the mechanism in the device, it is in a semi tense state, so that the operator has no sense of concern. In case of slip and fall, the pulling speed of the safety rope is significantly accelerated, and the locking system in the device will automatically lock. No more than 292 n of force is allowed to pull out the rope, causing no injury to personnel. When the load is relieved, the work will be resumed automatically. After work, the safety rope will be automatically recycled into the device for easy carrying.
