Fall Arrester using Qianye power spring

источник:Цянь Точность время:2022-9-14

The fall arrester is also called the speed difference device, which is a protective product. It is suitable for safety protection when the crane is hoisted to prevent the suspended workpiece from accidentally falling. It can effectively protect the life safety of ground operators and the damage of the suspended workpiece. It is used in metallurgical automobile manufacturing, petrochemical industry, engineering construction, electric power, and ships. , Communications, pharmacy, bridges and other high-level workplaces.

The protective effect of the protective device product must pass. The power spring has a retractable function and is an ideal part of the gravity dissipator used in the dropper. The anti-fall system is connected between the fixed points of the cable harness, and they can stop the user from falling in the first time. Even when the power spring is fully deployed, the gravity dissipator of the dropper can prevent the user from being hit in the event of a fall.

The advantages of Qianye power springs are divided into natural power springs and pre-force power springs according to their relaxed shape. In contrast, the pre-force type power spring can store 25% to 55% more torque and provide more effective turns.

When using Qianye power spring as its parts in normal use, the safety rope will expand and contract freely with the human body. Under the action of the mechanism in the device, it is in a semi-tensed state, so that the operator has no sense of worry. In the event of a fall, the pulling speed of the safety rope will be significantly increased, and the internal locking system will automatically lock. Make the safety rope pull out the distance not more than 0.2 meters, the impact force is less than 2949N, and there is no harm to the person who missed the foot. Work automatically resumes when the load is released. After the work is completed, the safety rope will be automatically recovered into the device, which is easy to carry. The anti-dropping device adopts Qianye’s power spring, which has high safety factor and good reliability, and effectively solves the accident caused by hitting other objects due to the excessive fall and swing amplitude of tilt operation.

Shenzhen Qianye Precision Metal Co., Ltd. is a professional manufacturer of high-precision springs, constant force springs, power springs, variable force springs, stainless steel carbon brush springs and other springs. The company integrates product development, production, sales, and service, and has various skilled and experienced engineering and management personnel.
