INTRODUCTIONS

            Fall arresters made of sealed aluminum housing are designed for helping restrain people from vertical  falls while allowing move freely. Automatically controlled by the changed speed, fall arresters are personal fall protection systems against falls from a height that arrest a free fall, which limit free-fall distance, deceleration distance and the impact force on the body caused by falling from height. And the most ingenious aspect about fall arresters is that the retracting feature eliminates tripping hazards and controls the falling of body effectively by brake system. They are useful in reducing possible injuries that pose a threat to professionals that work at dangerous heights.

           They are used to protect against falls, with a great deal of freedom of movement due to the cable length is adjusted automatically thanks to a recall system integrated into the device, it works like a seatbelt when a fall occurs. When a sudden acceleration takes place (a fall), the fall arrest device blocks immediately, stopping the fall within a fraction of a second,while the inertia-locking mechanism arrests a fall within inches of activation and can control the falling by brake system of resistance to ratchet double disc, the rope is free to get into work any time.
The retractor connects to the fixed sling of the person who is parallel to the hook of the crane must be attached to an approved point which can be endured 23KN. The block can be attached to an anchorage point or safety harness. Fall arrester's lifeline will extend as the user moves away, and retract automatically enabling the user to move within a recommended working area and uninhibited at different levels at normal speeds. The rope of arresters is free to get into work at any time. When an acceleration takes place, the fall arrest device which works like a seatbelt blocks immediately, stopping the fall within a fraction of a second, and limits free-fall distance, deceleration distance and vertical impact force on the body. The retracting feature eliminates tripping hazards while the inertia-locking mechanism will arrest a fall within  inches of activation and control the body by brake system of resistance to ratchet double disc. The immediate brake reaction (an automatic speed sensing braking function) reduces the fall height, stops the fall, reduce the impact of forces imposed on the user to safe levels (less than 6 KN) and suspends the person until either self-rescue or outside assistance becomes available. The required stopping power is supplied by an integrated braking system.

           Smooth and quiet operation engineered spring retraction tension are not designed to pull or drag a worker to improve productivity and reduce fatigue. This fall arrester work with auto rescue descender/self-retractable descender, self-retractable descender lowers the user automatically due to its integrated descent brake after a fall. Its counterpart is inertial reel type fall arrester/ fall arrest retrieve block, which is in a durable cast alloy housing with galvanized steel wire cable and built in recovery mechanism that can be engaged for rescue or to lift or lower a casualty and is operated by winding the handle, which can only be used as a secondary device as it is not designed for full man riding other than for an emergency rescue.

           Fall Arresters are used only with full body harness rated to fall arrest and also certified for horizontal/ inclined use if used in coordination with an energy absorbing lanyard. It is ideal for climbing applications where vertical mobility is needed and easy to install on different types of anchor through the use of several connectors, also easy to connect to the harness using the M47 swivel connector fixed on the dissipater. This product has a unique side payout design which reduces wear on the cable for smooth operation with less drag. The advantages of them are novel structures and innovative processes. Its lock is stable and safe enough to guarantee safety. Also, it is convenient to use fall arresters at large range of activity. It has the strength of high temperature resistance, wear resistance and light weight. Retractable Fall arresters can stuck wire rope when you have a fall as it can avoid the fall from scaffolding, metal structures or other high-altitude operations. Additionally, its double brake tooth is safe and reliable. Its brake system utilizes special material and special fabrication processing, and it is anti-corrosive, shockproof and wear-resistant. This product can stop dropping automatically within 0.2 meter to make worker safe when the speed of steel wire rope is more than 1m/sec.

            They are widely used in construction, manufacturing, fabrication, oil & gas, marine, general maintenance, mine industries, civilian use and personal life. They can also be used in some work activities at heights in Scaffolding, metal structures, rope access, confined/narrow spaces, elevating platforms, leading edge, roof and inclined planes. For example, safety fall arresters are used for situations where workers use an overhead anchor point, because the fall arrest device minimizes the fall distance by the immediate fall arrest when a fall occurs. However, in some cases, they’re also used in horizontal fall protection systems.  

           They also named fall protection devices, wire rope falling protectors, retractable climb, safety catchers, retractable fall arrester blocks, wire rope retractable fall arresters, safe retractable wire rope fall arresters, parachute protections, retractable anti-falling devices, self-retracting lifelines(SRL), self-retracting lanyards, rigid lifelines fall protection systems, composite retractable, automatic fall arrest devices, self-retractable lanyards or self-retracting lifelines, anti-drop tool lanyards, safety protection tool lanyards, retractor.

Detailed Description

1. Shell/casing/cover/housing

Fall Arrester is made of sealed aluminum Jacket or plastic shell, It is a composite unit on the market easy to handle and transport to/from jobsites.
In china, most of fall arresters’ shell are made up of high impact strength, one step shaping integrated aluminum alloy which is light, durable, sturdy, corrosion-resistant, non-disassembling/disassembly free, anti-shock and anti-dropping to prevent breakage and nearly indestructible, few of them are made of Polymer, glass-filled polyurethane, ABS, or nylon shell (one kind of plastic) which are all high impact strength and withstands the harsh, corrosive working conditions of the toughest applications thus ensures efficient and safe operation, while inner parts are #45 steel (Corrosion resistant galvanized steel internal working components to extend the life and reduces if any replacement costs). It is the lightest, most rugged lines which are smooth with round edges to increase durability.

2.  Rope/cable  

Comes with high quality galvanized steel, stainless steel wire rope, webbing rope or synthetic rope lifeline with 4.5 mm or 5.0mm which is connected to a snap hook that is connected to the harness of a worker and has been tested in a simulated fall over an edge and passed national standard and its tension allows the user to move freely around the work area, automatically retractable rope or webbing (belt strap) retracts or extends to different lengths as required and keeps the connection taut at all times, By walking further away from the fall arrest device, the device unrolls the rope/webbing until it runs out and automatically retracts the rope/webbing when the worker comes closer again it rolls up, this makes sure that the webbing is always taut with no slack and excess webbing doesn’t hinder the worker. Roller nozzle reduces wear on cable.
Rope Lanyard offers some elastic properties for many different types of fall arrests, and are mainly used for restraint purposes. Web Lanyard are ideal for restraint purposes when the potential fall hazard is less than 2 feet.

6. Self-retracting (tensioning) mechanism

When the self-retracting mechanism doesn’t function properly, there is a danger that the wire rope or webbing will sag when the worker moves closer to the equipment again. As a result, the fall Arrester will not block immediately when a fall occurs and the fall distance may be significantly longer, possibly causing serious injuries.

7. Breaking mechanism

Unique quick centrifugal activated steel breaking mechanism (lock mechanism) is an innovative engineering solution to arrest falls by two-disc anti-ratchet braking/locking system which effective control of the body to fall out of control job when free to pull the rope to use under normal up and down (less than 2 meters per second) without affecting the normal operation.
Anti-ratcheting twin/double disc brake system uses special materials, fabrication processing and treatment with first “double U shaped brake” technology. It is corrosion resistance, freezing resistance, impact resistance and wear resistance. There are three independent locking mechanisms.
A properly working braking mechanism is essential for safe use of an automatic fall arrest device. This has to be tested prior to each use by pulling the webbing firmly downward when holding the casing. Pull until the brake engages without slipping and release, so the webbing retracts back in the casing.

11. Indicator (optional)

Fall stress and visual impact loading indicator on snaphook integrated on the connector to show use in fall situation and alerts the user when the unit has been subjected to a load.
The fall energy dissipater (ESD) is also a fall indicator, ensuring that the device will not be used again after a fall, which is triggered when a fall is arrested.
The fall indicator is a colored part at the attachment point (attachment end) of the snap hook. When it’s not activated, a green color is showing to point out it’s safe to use the equipment. After a fall has been arrested and the indicator is activated by the forces, a red colored piece is visible. In this case, the equipment has been subject to a fall and needs to be checked thoroughly by a competent person whether it can be used again or needs to be replace.

20. Retractable lifeline systems

Retractable lifeline systems give fall protection and mobility to the user when they are working at heights, but require mobility in order to work.

21. ESD or AES

Fall arrester block with energy system dissipater (ESD) or absorbing end system (AES) ensuring that the user will undergo an impact no less than 600 daN even with a fall when the cable has been completely unwound/fully extended.
ESD ensures absorption of a fall even when the webbing is fully unwound and the ESD system also acts as a fall indicator ensuring that the device is not used again after a fall.
The AES system reduces the strength of the impact on the user’s body in the event of a fall. It efficiently protects the end of the strap secured to the end of the cable against the risks of rupture which can be caused by sharp edges found on terrace roofs.

Others

Minimum breaking force/strength of the whole: 12KN
Maximum force in the event of fall or internal braking mechanism to reduce the fall arrest force need to be less than 6KN (internal shock absorption system).
Compliance Standard: GB2454-2009 << TEST METHOD FOR PERSONAL FALL PROTECTION SYSTEMS>> (ANSI, EN360 and ANSI Z 359)
Service Life(times) >20000
 All metal parts after 48h salt spray test and additional testing against falls over edges. 

Caution
 One of the biggest challenges in Fall Arrester or fall protection is when the anchorage is too high to access and the clearance distance is too small.
 It need to store in a cool dry place, far away from chemical, water, direct sun light and sources of heat and vibration.
 Ensure cable section is completely retracted before storage. This is especially important when retractors are left in place outside as components of a permanent fall protection system.
 Fall protection components are designed to be used with the same manufacturer's approved components and connecting subsystems. Fall protection manufacturers strongly recommend that fall protection users take full advantage of the functional compatibility built, tested, and approved within the same manufacturer's fall protection components. The manufacturers cannot guarantee the compatibility of substitutions and the use of substitutions may jeopardize the safety and reliability of the complete system.
Need to be checked before each use, during this check, multiple damages or deformations may indicate that the safety of the equipments are compromised. This means that they have to be checked by a competent and certified inspector for all Harness, Lanyard, Lifeline to determine whether they’re safe to use again or they have to be taken out of service immediately.
Although it might look okay and safe from the outside, internal or small damages may occur after a period of extensive use.
The casing might start to show cracks, the wire rope or webbing can be damaged, connectors may not close or lock properly any more, etc. That’s why it’s of great importance that an automatic fall arrest device is checked thoroughly before each use.
Just as all PPE, the automatic fall arrest device must be checked and re-certified annually to guarantee safe use. This check needs to be done by a competent person, who is trained and certified to perform such checks.

Something we need to know:
 Fall Arrest – Overview & Review
 We must concern about the continued safety and well-being of their employees, especially in the area of fall arrest and fall protection. It is time for companies to get more serious about fall arresters--fall arrest, positioning, suspension, and retrieval fall arrest. If there is a risk that a worker may fall from an elevated position, a fall arresting system is required.
 The system should be used anytime working at 6 feet or higher. Working height is the distance from the walking or working surface to grade, or lower level. This system will only be triggered should a fall occur. The only product recommended for to arrest a fall is a full body harness with a shock absorbing lanyard or a retractable lifeline. The full body harness distributes the force throughout the body, while the shock absorbing lanyard decreases the force of the fall.
 Positioning
 This type of system holds workers in place while keeping their hands free to do their work.  If the worker leans back, the system becomes active. This system is not designed for fall arrest purpose, just to limit the possibility of a fall taking place.
 Suspension
 Suspension lowers and supports a worker in hands free work environment. For example, this is commonly used in painting industries and among window washers. The system is not designed to arrest a free fall, it should be used with a backup fall arresting system.
 Retrieval
 Consideration should be given to planning for retrieval should a fall occur. Having a proactive fall management program saves lives.
