Sound and light alarm system & limit switch

1) Sound and light alarm system

Function: The sound and light alarm system is mainly used to provide visual and auditory warnings during the operation of the crane. When the crane approaches the limit position, the load exceeds the standard, or a fault occurs, the system will sound an alarm to alert the operator.

Components: The warning light is usually a flashing red or yellow light, which can visually alert the operator to the danger. The buzzer makes a sound to attract the operator's attention, especially in a noisy environment.

Application scenario: During the start, stop, and operation of the crane, the alarm is issued in time to ensure that the operator has a clear understanding of the equipment status.

2) Limit switch

Function: The limit switch is used to monitor the operating range of the crane to prevent it from exceeding the designed limit position and ensure the safe operation of the equipment.

Type: The upper limit switch is used to limit the operation of the crane when it is raised to the maximum height to prevent the lifting parts from colliding with the ceiling or other obstacles. The lower limit switch is used to limit the operation of the crane when it is lowered to the lowest position to avoid equipment damage or material falling. The side limit switch is used to limit the lateral movement of the trolley to ensure the stable operation of the crane on the track.

Working principle: Limit switches are usually set at key positions of cranes. When crane components (such as hooks, main beams, etc.) touch the limit switches, the switches will automatically cut off the power supply or stop the motor to ensure the safety of the equipment.

10.Safety Devices

1) Overload protection device: prevent the crane from overloading. When the actual load of the crane exceeds the rated lifting weight, the overload protection device will automatically cut off the power supply or sound an alarm to prevent damage to equipment and personnel.

2) Emergency stop device: used to manually stop the operation of the crane in an emergency. The operator can quickly cut off the power supply of the equipment by triggering the emergency stop button to prevent accidents.

3) Windproof device: prevent the crane from being blown by strong winds when working outdoors. The windproof device can be a mechanical locking device or an electric locking device. When the wind speed exceeds the safety standard, the crane will automatically lock to prevent the equipment from being dangerous due to wind.

4) Electrical protection device: prevent equipment damage or safety accidents caused by electrical faults. Electrical protection devices include short-circuit protection, undervoltage protection, phase failure protection, etc., which can automatically cut off the power supply when the electrical system is abnormal to prevent damage to the equipment or affect safety.

5) Anti-sway device: reduce or prevent the swing of the hook and load during lifting, ensure the stability of material handling, and prevent the material from falling off due to swinging.

6) Buffer device: A buffer is installed at the terminal position of the crane. When the equipment or vehicle approaches the end of the track, the buffer device can absorb part of the impact force to avoid damage to the equipment or personnel.

11.Control Mode

1) Ground handle control: The operator controls the operation of the crane by holding a control handle connected by a cable. There are multiple buttons on the handle, which are used to control the lifting, lateral movement and trolley movement of the crane. The cable is generally of a certain length, allowing the operator to operate at a safe distance.

2) Wireless remote control: The operation of the crane is controlled by a wireless remote control, which usually has buttons or rockers to control lifting, lateral movement and trolley operation. Without cable connection, the operator can move freely and operate the equipment at a long distance.

3) Cab control: The operator sits in the cab installed on the crane and operates directly through handles, buttons or joysticks. The cab is usually installed on the trolley or car of the crane, and the operator can directly observe the lifting operation site.

4) Centralized control (PLC control system): Use a programmable logic controller (PLC) for automated control to control the various actions of the crane through pre-programmed programs. The operator can control and monitor the operating status of the crane in the central control room or remotely through the human-machine interface (HMI).
