Customized Safety
for Your Elevator Installations

Elevator safety gear systems are essential safety devices in modern elevators. The main goal of these systems is to halt the cabin in the event of overspeed or a break in the suspension system, thereby protecting passengers that may be inside.

These systems typically rely on a braking mechanism that activates automatically when an abnormally high speed is detected.

When the system detects free fall or a dangerous increase in descent speed, the safety gears' brakes activate, creating friction against the guide rails and stopping the cabin in a controlled and safe manner. Some systems may also have additional mechanisms that help cushion the final impact, even in the event of a sudden stop.

In this way, elevator safety gear systems play a crucial role in preventing severe accidents in elevators, providing an extra layer of security for users.

Overspeed governors in elevators are vital devices for maintaining safety in these facilities. Their primary role is to detect if the elevator car exceeds a predetermined speed during its movement, whether ascending or descending.

An overspeed governor generally involves a series of mechanical or electronic components continuously monitoring the elevator's speed. This often involves a centrifugal mechanism that spins at a speed proportional to the elevator's speed. If the elevator begins to move faster than permitted, this spinning mechanism triggers a series of actions to reduce the speed.

One such action includes the activation of the safety gears. It may also involve disconnecting the elevator's motor to prevent cabin acceleration. In some advanced systems, overspeed governors can interface with the elevator's control system to reduce speed gradually and smoothly, instead of a sudden halt.

Finally, overspeed governors often collaborate with other elevator safety systems, such as safety gear systems. If the overspeed governor detects an excessive speed indicative of a free fall, it could activate the safety gear system to bring the elevator to a safe halt.

Unintended Car Movement (UCM) systems in elevators are a collection of safety devices that detect and stop the elevator when an uncontrolled cabin movement occurs, i.e., a movement not ordered by the elevator's control signals. These systems are a safety essential for elevators and a requirement as per the EN81-20 standard.

UCM systems aim to prevent accidents that could happen if the elevator car unexpectedly starts moving, either upwards or downwards. Such movements can occur due to various malfunctions, such as a failure in the braking system or a fault in the elevator control system.

UCM systems detect these uncontrolled movements by continuously monitoring the elevator's direction and speed. On detecting an uncontrolled movement, they instantly activate a set of safety measures to halt the car. This could include activating the safety gears and disconnecting the elevator's motor to prevent cabin accelerations.

Additionally, some advanced UCM systems can also interact with other elevator safety systems, like the safety gear systems, providing an extra layer of protection if the uncontrolled movement results from a free fall.

An elevator safety system is a comprehensive set of components and protocols designed to ensure the safety and optimal operation of an elevator. These systems include various devices and mechanisms, such as safety gears, overspeed governors, Unintended Car Movement (UCM) systems, and a wide array of additional safety components.

Elevator safety systems are essential for several reasons. Firstly, they safeguard the life and well-being of elevator users, preventing accidents and ensuring a safe and smooth ride. Secondly, safety systems protect the elevator itself and the building infrastructure, preventing damage that could be costly to repair. Lastly, in many jurisdictions, the use of certain safety devices in elevators is a legal requirement.

1. 1. Safety gears for elevators: Safety gears are essential devices that intervene to halt the elevator in case of excessive descent acceleration, or in some instances, upward acceleration. We offer both progressive and instantaneous safety gears, providing safe and controlled stopping in emergency situations.
2. 2. Overspeed governors: These devices are fundamental for controlling the elevator's speed. If the elevator exceeds a certain speed, the overspeed governor activates, initiating a safe braking process.
3. 3. UCM systems: Our UCM systems ensure that the elevator, when at floor level, cannot move unless all doors are secure and closed. This prevents potentially hazardous accidents.
4. 4. Machines and pulleys: Luezar Eco's machines and pulleys are designed to operate efficiently and safely under heavy loads, ensuring the reliability of the elevator system. Furthermore, our tensioning pulleys and tensioners contribute to the correct tension and alignment of the cable, key factors for the elevator's proper operation.

At Luezar Eco, we offer both instantaneous and progressive safety gears to adapt to the diverse needs of our customers. Although both are crucial for elevator safety, they function in slightly different ways:

• Instantaneous safety gears: This type of safety gear is activated instantly when it detects an excessive acceleration in the elevator's descent. After activation, the instantaneous safety gear abruptly stops the elevator cabin to prevent an uncontrolled descent. This type of safety gear is particularly useful in emergency situations where a swift response is critical for the safety of the elevator occupants.
  Progressive safety gears: On the other hand, progressive safety gears are safety devices that engage during both the ascent and descent of the cabin, offering a more gradual and smoother stop. Their role is to progressively halt the cabin when a preset speed limit is surpassed, whether in ascent or descent. This type of safety gear minimizes the impact of the halt on the elevator passengers, delivering greater comfort without sacrificing safety.

Both types of safety gears are vital for elevator safety, and at Luezar Eco, we take pride in offering both types with the utmost quality and reliability, always guaranteeing the safety and well-being of elevator users.

Luezar Eco's progressive safety gears are designed to augment elevator safety by providing a braking system that acts during both the ascent and descent of the cabin. They engage when the speed of the elevator cabin exceeds a pre-set limit, whether in ascent or descent. Unlike instantaneous safety gears, progressive ones halt the cabin gradually and in a controlled manner, which minimizes the impact and enhances passenger comfort.

In terms of usage, progressive safety gears find application in a variety of scenarios. They are particularly useful in high-speed or intensively used elevators, where the chance of surpassing speed limits is higher. Also, their ability to deliver a gentle, controlled stop makes them ideal for use in environments where passenger comfort and safety are paramount, such as in commercial, residential, and office buildings. At Luezar Eco, we are continually striving to enhance and adapt our progressive safety gears to the specific requirements of our customers.

Luezar Eco's overspeed governors play an essential role in elevator safety as they are responsible for regulating and maintaining the speed of the cabin within the established safety limits.

These devices act as a constant speed monitoring system for the elevator. When the cabin attains a certain speed, the overspeed governor is activated, and if necessary, it can trigger the activation of other safety systems such as safety gears, thus helping to prevent dangerous situations.

In detail, overspeed governors work through a pulley managed by a mechanical or electronic system that tracks the movement of the cabin. When this movement exceeds the maximum allowed speed, the overspeed governor comes into play, activating the braking system or safety gear to safely stop the elevator.

Overspeed governors are crucial in all types of elevators, especially those that operate at high speeds or in high-rise buildings. At Luezar Eco, we offer a wide range of overspeed governors, all designed and manufactured following current safety regulations, ensuring that our customers receive the highest quality and most reliable products.
