Sound and light alarm system & limit switch

sound and Light Alarm System & Limit Switch in a 3-Ton Aluminum Gantry CraneThe sound and light alarm system and limit switch are crucial safety components in a 3-ton aluminum gantry crane. These features ensure safe operation by alerting operators to potential hazards and preventing overtravel or damage to the crane.

Sound and Light Alarm System;The sound and light alarm system enhances operational safety by providing visual and auditory signals during critical crane operations.Key Features:Auditory Alarm:Emits a loud sound (typically 85–120 decibels) to alert workers of crane movement, load lifting, or potential dangers.

Durable and Weather-Resistant:Designed for indoor and outdoor use, resistant to dust, water, and vibration.Benefits:Enhances workplace safety by reducing the risk of accidents.Ensures compliance with safety regulations in industrial environments.Increases awareness of crane activity, particularly in busy or low-visibility areas.

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).
