An elevator overload protection device is a crucial safety feature. When an elevator is unattended, overload protection is crucial for the safety of passengers, cargo, and the elevator itself. A residential elevator overload occurs when the elevator's rated load exceeds its capacity, resulting in a system alarm and the doors not closing.
Overloading can cause accidents, potentially fatalities or even life-threatening situations. Therefore, elevators are equipped with overload protection devices.
Residential elevators use a weighing device to determine whether the elevator is operating under heavy or light load. A preload current is applied to the motor during heavy load startup to prevent the elevator car from sliding down or up during startup. Modern elevators automatically adjust their starting torque when the load is less than the rated load, providing a starting current tailored to the actual load. This ensures a smooth and comfortable start, ensuring optimal comfort, stability, and energy efficiency.
Many modern elevator features, such as anti-tampering, fully loaded direct travel, and overload protection, are based on the load inside the elevator car. A home elevator is defined as an elevator installed in a private residence for the exclusive use of a single family member. It can also be installed in buildings not used by a single family, providing access to the residence, but is inaccessible to the public or other residents.
Unlike public elevators, private elevators are designed for single-family use. Therefore, home elevators require high safety features. For elderly or children in the home, if a power outage or malfunction occurs while the elevator is in use, it's best to choose a home elevator equipped with automatic rescue devices and automatic dialing to provide maximum protection. Of course, the manufacturer will also require additional equipment costs.
