Elevator weighing devices are our company's mainstream products, and The elevator/lift weighing device( EWD-RL-J2 )is a typical cylindrical weighing device.

Description:

This is our company's Load weighing devices of Elevator  (model: EWD-RL-J2).

this device could adopt serval load cell(XCL-Y/3411,XCL-YH/5018,,XCL-Y/5222,XCL-ZL/W,XCL-T/A)

This device has Six major features:
No.1  It is Easy to   install  and debug .
No.2 Installed  on   the ropes head of elevator.
No.3 alarm  Code is  visually displayed in LED screen.
No.4 Two  programmable alarm values (Full Load and Overload).
No.5 Weighing Accurate about 0.5 %.
No.6 Fits most common elevator models.

The elevator/lift weighing device (also known as the elevator load-bearing device) is a key component in the elevator safety system. Its core function is to ensure the safe operation of the elevator by monitoring the weight in the car in real time. The specific functions are as follows:

1. Prevent overload accidents

When the weight in the elevator cabin reaches 95% of the rated load, the elevator/lift weighing device will trigger a full load signal; if it exceeds 102%~110% (slightly different in different standards), the overload protection will be activated, preventing the elevator from running and triggering a buzzer or warning light.

After the overload protection is activated, the elevator may appear to be unable to close the door or stop running until the load returns to normal.

2. Feedback load information

The weight is converted into an electrical signal through a pressure sensor, and after processing, real-time load data is provided to the control system for adjusting the elevator operation status (such as starting compensation functions or anti-tampering programs).

Some devices can also distinguish between different states such as light load and full load to optimize elevator energy efficiency.

3. Cooperate with other safety functions

Work in conjunction with the counterweight device to balance the mass difference between the car and the counterweight (usually the counterweight mass = car mass + 40%~50% of the rated load), reduce motor power consumption and extend the life of the wire rope.
