Product Introduction

     During the operation of tower clock equipment, various malfunctions inevitably arise due to human factors such as materials, craftsmanship, and environment. Repairing the large clock is an effective measure to eliminate fault risks, extend the service life of the tower clock equipment, and maintain the clock in optimal condition. This work involves:

• 1. Inspect the tower clock movement and control section. Constant on-off circuit switching is damaging to the circuit and movement, so the most prone to damage in a tower clock is the movement. Each start and stop of the tower clock causes the hands inside the clock to shake, thereby reducing the lifespan of the movement and necessitating repairs.

• 2. Calibration of the timekeeping. Modern school bells are equipped with a feedback anti-freezing switch on the movement, introducing an additional closed-loop control. This ensures that the movement provides a feedback signal to the master clock control system with each operation, enabling the system to automatically detect the movement's status and make timely automatic adjustments to ensure accurate timekeeping. For instance, if the two needles are operating, the master-slave clock system employs closed-loop control to maintain asynchronous operation between the slave and master clocks. It indicates that if the tower clock's timekeeping is inaccurate, it is necessary to seek the manufacturer for tower clock repairs.

• 3. Inspect Lighting: Tower clocks are typically outdoor installations, so adequate lighting is essential. The on and off times are automatically controlled by the system. Reduce the frequency of tower clock maintenance and building tower clock repairs.

• Belfries, tower clocks, rooftop grand clocks, and clock tower repairs primarily consist of three main parts:

1. The appearance display section includes the face, hands, numbers, and the luminous illumination of the face. Check for rust, whether the hands or number hands are loose, and for any potential safety hazards. As the large clock is installed at a height, repairing the appearance is extremely inconvenient. Therefore, choosing a reputable manufacturer and installation crew is crucial.

Two, the electrical part of the grand clock control, which serves as the brain of the grand clock, has a high technical content and requires a high level of expertise from maintenance and service staff. Generally, a certificate is required to take the position.

Three, the movement core and mechanical transmission are the executing mechanism of the grand clock. The movement cores produced by Yantai Kexin Watch Co., Ltd. use material beryllium bronze for shaft bushes and 45# steel that has undergone strict mechanical heat treatment, significantly enhancing the core's wear resistance. The fully enclosed design ensures maintenance-free and保养-free operation, guaranteeing a lifespan of 50 years.

• In summary, large-scale clocks demand a high level of skill from maintenance personnel. They must possess both electrical and mechanical expertise, be brave yet meticulous, and capable of performing高空 work independently. Our company is capable of repairing tower clock equipment from various manufacturers across the nation. We offer free on-site inspections, propose repair plans, and upon customer approval, we sign a maintenance warranty contract. Products repaired by our company come with a free three-year warranty, during which no additional fees are charged.
