INVT's use of construction hoists
"Slip" maintenance
"Slipping" refers to the loss of electric drive and control of the construction hoist, which will cause uncontrolled operation, resulting in rushing to the top or squatting. This kind of slipping accident can endanger the lives of passengers and cause great damage to the elevator itself.
INVT has an excellent motor drive algorithm to ensure the low-frequency full torque output, and the built-in motor disconnection maintenance function improves the system response level from seconds to milliseconds, which can effectively avoid the phenomenon of "slipping".
Smarter voice announcements
In some of the news reported in the past, severe overload was the hardest hit area of the incident. Safety regulations in the cage passengers, loads should be evenly distributed, to avoid focus, it is strictly forbidden to overload.
INVT's control system can make a judgment according to the information collected by the camera on the number of people carrying and whether to wear a safety helmet, and if there is a violation, the system will announce a voice warning, and the construction elevator cannot be started.
A more comfortable ride on the elevator
When the construction hoist goes down, the moment the gate is loosened, the torque changes suddenly, and the cage is affected by gravity, which will cause slight shaking during the start.
Regarding this kind of shaking, INVT deals with this problem through positive torque, so as to achieve the effect of safety and comfort coexistence in the rise and fall to the shutdown, and accurately control the lifting and lowering of the construction hoist, which is safer, more comfortable and stable.
More effective security maintenance
On the basis of the original mechanical travel switch, INVT increases the electrical soft limit maintenance function, so that the operation of the cage is safer, and when the external limit fails, it can still stop normally to avoid safety incidents.
Cloud control system
Construction hoist + INVT industrial Internet can complete real-time monitoring of the operation status of construction hoist equipment, so that equipment, personnel and affairs can be efficiently interconnected.
INVT makes the device more intelligent, and can output various types of data statements according to transaction requirements; The common problems and corresponding treatment methods are refined, and the corresponding fault alarm information can automatically trigger emergency treatment plans and prevention tips, complete the rapid standard push operation process, and greatly improve the efficiency of enterprise operation and management.
