Working principle and technical advantages of Greateagle fall arrester

Active locking mechanism, precise response to the moment of falling: Greateagle Safety's fall arrester adopts a highly sensitive automatic locking system. When the wearer is detected to be falling freely (usually with an acceleration of more than 1.5 m/s), the built-in centrifugal brake or inertial locking device will start the braking program within 0.2 seconds, quickly lock the rope or clamp the steel cable, so that the faller "suspends" in mid-air, effectively shortening the fall distance and minimizing the impact damage. This mechanism is similar to the principle of car seat belts, but more complex and stable. It can maintain normal functions at high altitudes, slopes, ladders or irregular terrains, and can respond to the falling dynamics in real time even if the wearer is in a non-vertical state such as hanging upside down or flipping.
Automatic rope retraction structure to improve the convenience of operation: Some Greateagle models adopt a self-retracting structure (Retractable Type), and its built-in spring automatic reel system can adjust the length of the safety rope in real time-the rope automatically extends when the operator climbs up or moves, and automatically retracts after release. This "follow-up" rope length adjustment can prevent the rope from dragging on the ground or tying, improve the cleanliness of the site, reduce operational obstacles, and greatly improve the wearing experience. It is especially suitable for occasions with frequent movement and repeated climbing.
Buffering and shock absorption system to reduce the impact of falling: In order to further reduce the impact damage caused by falling, Greateagle integrates a buffer bag and a buffer belt structure in the braking system. At the moment of locking, the flexible material is stretched to absorb part of the impact force, making the braking process smoother, thereby effectively protecting the operator's spine, hips and pelvis, and avoiding secondary injuries caused by sudden stops.

Various structural forms, suitable for different operating scenarios

Greateagle Safety Products(Ningbo) Co., Ltd.'s fall arrester has developed a variety of product types based on application scenarios and fixing methods, which are widely used in different industry needs:
Self-locking fall arrester: The self-locking fall arrester adopts a closed shell structure design, with an automatic retractable steel wire rope or high-strength aramid braided belt inside, and has the function of automatic rope retraction and release. It can adjust the rope length in real time according to the operator's movement dynamics to avoid rope dragging on the ground and entanglement, and improve operation flexibility and on-site safety. This type of protector is lightweight and easy to operate. It is particularly suitable for high-altitude work scenarios that require frequent up and down movements, such as power inspection, tower climbing, and communication equipment maintenance. The rope length is complete, with common models of 6 meters, 10 meters, 15 meters, and 30 meters, etc., to meet the needs of different working heights; the shell part is made of impact-resistant ABS engineering plastic or aluminum alloy, which has good durability and fall resistance, and can reduce the burden of wearing. The rope is mostly made of galvanized steel wire rope or aramid fiber belt, which has both high strength and corrosion resistance, ensuring stable and reliable fall protection under complex working conditions.
Rail-type fall protector: The rail-type fall protector is designed for vertical climbing operations and can be used with vertical rail systems such as building towers, elevators, and wind power towers. The protector slides smoothly in the vertical direction through the rail device, and the operator remains flexible during the climbing process. Once a fall occurs, it will automatically lock on the rail and brake quickly to prevent a fall accident. This type of product is widely used in high-altitude vertical operation scenarios such as construction, elevator maintenance, and wind power equipment maintenance, providing continuous and reliable protection support for up and down movement.
Rope clamping type: The rope clamping fall protector is installed between the fixed anchor point and the soft safety rope. It relies on the friction between the device and the rope to achieve the automatic locking function. When the operator slips, the device will quickly clamp the rope to prevent further falling. This type of protector is usually used in conjunction with a professional climbing rope with a diameter of 11mm or 12mm. It has the characteristics of compact structure, easy operation, and sensitive locking. It is particularly suitable for short-distance, high-frequency repeated up and down climbing operation scenarios, such as warehouse stacking operations, high-rise shelf maintenance, equipment inspection, etc., providing efficient and flexible safety protection for operators who frequently move vertically.

Application areas

The application of Greateagle fall arresters has covered many high-risk operation industries and has become the standard configuration of many engineering general contractors and industrial customers around the world:
Construction and bridge construction: In the construction industry, especially in high-rise building and bridge construction, tasks such as steel structure installation, high tower hoisting, curtain wall glass hoisting and maintenance require workers to perform precision operations at heights of tens or even hundreds of meters. Such operations often involve walking in mid-air, crossing beams or columns, or operating on temporary scaffolding. The center of gravity is unstable and there is a lack of stable surfaces to attach to, which is a high-incidence scenario for high-altitude falls. Greateagle's self-returning fall arrester can automatically adjust the rope length when the operator climbs up and down and moves horizontally, and quickly locks in the event of a slip. It forms a complete protection system with a full-body safety belt and high-strength anchor points, greatly improving the safety factor of the operation.
Wind power and power industry: In the wind power industry, maintenance personnel need to enter the wind power tower and climb tens of meters to inspect wind turbine blades, lubricate gearboxes, and maintain cable systems; the power industry faces complex scenarios such as high-altitude equipment commissioning of substations, high-altitude inspection and maintenance of transmission towers, and maintenance of overhead lines. Due to the remoteness of the operating area, high vertical space, and drastic weather changes, the sensitivity and reliability of the fall protection device are extremely high. The Greateagle Safety Products(Ningbo) Co., Ltd. rail-type fall protection device is used in conjunction with the vertical lift or tower rail to provide full protection for the operator during the up and down movement. Once it slips, it will be locked immediately, greatly reducing the probability of accidents.
Communication and signal engineering: Communication engineering involves a large number of high-tower construction and inspections, such as 5G base station installation, communication tower assembly, telecommunications antenna replacement and commissioning, etc. Construction personnel need to carry tools to climb to the top of the tower tens of meters high to carry out operations. In such working conditions, the platform is usually small and the wind is strong, which can easily cause instability or even tool drop, and there is a great risk of falling. Greateagle Safety Products(Ningbo) Co., Ltd.'s lightweight rope clamping fall arrester is small in size and light in weight, which is convenient for technicians to carry and flexibly fix at any height of the tower. It can achieve continuous fall protection without affecting the flexibility of operation, ensuring the smooth progress of communication guarantee work.
Aviation and logistics warehousing: In aviation maintenance and large-scale logistics industries, scenes such as aircraft cargo holds, high-level wing inspections, three-dimensional shelf storage and retrieval, and high-rise area inspections in warehouses are also facing the risk of falling from heights. Especially when working in closed or narrow spaces, improper wearing or insufficient equipment performance may cause secondary risks of "falling and being unable to be rescued". The automatic rope-retracting fall arrester provided by Greateagle Safety Products(Ningbo) Co., Ltd. supports multi-directional mobile tracking, and the rope will not drag on the ground or entangle obstacles, which is suitable for rapid deployment in logistics warehousing systems. Its shell is light and sturdy, and will not cause additional burden. It is particularly suitable for logistics operators to carry out long-term high-altitude handling and positioning operations.
Chemical and shipbuilding industries: In industries such as petrochemicals, shipbuilding and tank maintenance, operators often need to perform tasks such as high-altitude welding, high-altitude painting, confined space operations, and scaffolding installation and disassembly. These workplaces are often accompanied by high temperature, high humidity, flammable and explosive or toxic gas environments. Without professional fall protection equipment, it is very easy to cause serious personal injuries and related accidents. Greateagle fall protection devices are equipped with stainless steel highly corrosion-resistant components and flame-retardant shell materials. They can be used for a long time in acid, alkali, oil and gas environments without performance loss, meeting the chemical industry's dual needs for "safety + durability". In addition, its quick hook design facilitates operation with gloves, improving efficiency and safety in extreme environments.
