GX HVLS Fan has taken a series of measures to protect everyone for everyone's safety. High Volume Low-Speed ceiling fan is suspended from the building beam. Underneath the HVLS ceiling fan, there may be workers and equipment in the factory, customers in the shopping mall, cattle in the dairy farm, and so on. In addition, the HVLS ceiling fans are enormous, reaching a diameter of 7.3 meters/24ft. Compared with small ceiling fans, HVLS ceiling fans have a certain weight.
Let's go through the security details employed by the GX Fan from top to bottom, starting at the top of the fan.
1) The cross-beam connection structure adopts an anti-skid groove design and cotter pin locking nut, which can prevent the steel beam clip from sliding off accidentally, and does not require drilling and welding.
2) Install a steel wire safety rope between the mounting bracket and the steel beam to prevent the HVLS ceiling fan from accidentally falling off.
3) We use a universal joint connection between the beam structure and the extension rod. The universal joint can reduce the torque transmission of the fan to the building. When the HVLS ceiling fan starts and stops, the torque of the fan blades and the motor can be decomposed to minimize the damage to the building and maintain the safety performance of the original installation. During installation, the universal joint is as flexible as a human joint, and the angle can be adjusted to achieve the best level of installation angle. Then HVLS ceiling fan can earn the minimum friction loss when running, like the wheel alignment of the car wheel, to achieve the best service life.
If the arc hole type rigid connection is used, it is impossible to perform two-way shock absorption. When the fan starts and stops, the resistance of the fan blade and the motor extends to the building, causing damage to it and causing a safety hazard.
4) Four steel wire traction cables keep the fan in a horizontal position to prevent the fan from shaking due to external forces, preventing the HVLS ceiling fan from shaking and falling off under the influence of external power.
5) GX HVLS fans use the double chassis instead of the single chassis used by other manufacturers. A dual chassis can upgrade from point contact to surface contact, and the HVLS ceiling fan is more evenly stressed. Even under the strong inertia of starting and stopping, the mechanical fatigue loosening and damage can be minimized, and the safety performance is greatly improved.
6) The fan blades are imported from American Airlines' high-performance aluminum alloy. The interior adopts the combination of Split and full reinforcement. If the built-in reinforcing ribs of the fan blade adopt the double-full rib method, the strength of the fan blade is relatively high, but the flexibility is insufficient. When the torsion force generates the reaction force, it can only be hit hard, which will accelerate the wear of the fan blade and bolts, and the fan blade is prone to long-term use.
The GX Fan adopts the plug-in connection method between the fan blade and the hub. This can make the insert contact with the inner cross-section of the fan blade, and the force is evenly distributed up and down, left and right. The wear of the inserts on the fan blades is relatively low, and the staff is more uniform. The clamp and the fan blade are locked and fixed by two bolts if the external clamp connection method is adopted. During the start and stop process of the fan, affected by the reaction force of the centrifugal force, the bolt position only depends on the complex buffer of the reinforcing ribs, which is accessible to It will cause wear and deformation of the fan blades and reinforcing ribs, resulting in the potential safety hazards. Moreover, only the upper and lower sides of the outer clip type are in contact with the fan blades, and the left and right are not subjected to force, which is easy to cause damage to the left and right direction forces.
L-shape safety buckle is used between the fan blade and the fan blade. Each fan blade is provided with an Associate in Nursing L-shaped safety link buckle to severally forestall the edge from slack.
In addition to the safety details of the HVLS fan itself, the installer is also an essential component of a successful and safe installation. All fan installation personnel on-site need to be equipped with necessary safety helmets, reflective vests, labor insurance shoes, and professional tools for installing fans. Climbing personnel must hold an ascending certificate.
