When should load weighing devices be readjusted?

Load weighing devices must be readjusted after new suspension means are installed because the new components can alter the balance and performance of the elevator system. The suspension means, which include cables, pulleys, or other support systems, directly impact the load the elevator can handle. Installing new suspension components can shift weight distribution or tension in the system, requiring recalibration of the weighing devices to ensure accurate readings and safe operation.

Regular adjustments ensure that the elevator accurately reflects the load it is carrying, which is vital for safety and efficiency. This process helps maintain compliance with safety standards and prevents potential overloading during operation, which may lead to failures or accidents. The timing of this adjustment is critical immediately after any changes to the system that could affect weight readings, such as installing new suspension means.
