6.Crane wheel

1) Function of wheels

Safe eot crane is Mobile support: The main function of the wheels is to support the movement of the crane on the track and ensure the smooth operation of the crane.

Load distribution: The wheels help to evenly distribute the load of the crane, reduce the pressure on the track, and increase the service life of the equipment.

2) Design requirements

Strength and rigidity: The wheels must have sufficient strength and rigidity to withstand the dead weight of the crane and various dynamic loads.

Wear resistance: Due to the continuous friction between the wheels and the track, the wheel material must have good wear resistance to extend the service life.

Anti-skid design: The wheel surface should be designed to be anti-skid to avoid sliding or slipping under heavy load.

7.Crane Hook

1) The hook is usually made of high-strength alloy steel or carbon steel to ensure its strength and durability under high loads. The choice of materials should take into account fatigue resistance and wear resistance. The design of the hook is usually U-shaped or closed, which can effectively grasp and fix the material to prevent it from falling off during lifting. The surface of the hook is generally heat-treated or coated to improve its wear resistance and corrosion resistance.

2) The hook is connected to the lifting mechanism through a wire rope and directly bears the weight of the hoisted object. During the lifting process, the hook needs to withstand the gravity from the material and its dynamic load. During lifting, the hook is raised and lowered through the lifting mechanism, allowing the material to move in the vertical direction while maintaining stability to ensure safety. The main function of the hook is to safely grab and lift various materials and ensure that the material does not fall off during movement. The design of the hook allows quick and easy connection with different types of hoists (such as lifting rings, grabs, magnets, etc.), improving the flexibility of the operation.

Motor

1) Common motor types, including asynchronous motors and synchronous motors, have the advantages of simple structure and stable operation, and are suitable for most crane applications. In situations where higher starting torque and adjustable speed performance are required, DC motors may be used to provide smooth acceleration and deceleration.

2) The motor converts electrical energy into mechanical energy to drive the operating mechanism of the crane. The rotation of the motor transmits power to the wheels or lifting device through the reducer to achieve the movement of the crane. Modern motors are often used in conjunction with frequency converters to achieve precise speed control and adjustment to meet the needs of different working conditions.

3) The motor is responsible for driving the operation of the trolley and the car, enabling the crane to move on the track for lifting and positioning of materials. The motor lifts the heavy objects to the required height through the lifting mechanism (such as the winch) to meet the requirements of different operations.

Sound and light alarm system & limit switch

1) Sound and light alarm system

The sound and light alarm system usually includes sound alarms and flashing lights, which are mainly used to send warning signals during the operation of the crane to improve the safety of operation.

Danger warning: When the crane is about to start or end work, the system will send out sound and light signals to alert the surrounding personnel.

Overload alarm: When the crane reaches or exceeds the safe load, the sound and light alarm system will automatically activate to remind the operator to take measures to avoid potential safety hazards.

Fault prompt: When there is a failure or abnormality in the equipment, the sound and light alarm system can issue an alarm in time to remind the operator to check and maintain.

2) Limit switch

The limit switch is a safety protection device for the crane, which is used to control the operating range of the crane to prevent it from exceeding the preset safety position.

Upper and lower limits: The limit switch is used to set the upper and lower movement limits of the crane. When the lifting mechanism or trolley reaches the set limit position, the limit switch will cut off the power supply or sound an alarm to prevent it from exceeding the safety range.

Prevent collision: The limit switch can effectively prevent the crane from colliding with other equipment or obstacles, ensuring the safety of equipment and personnel.

Automatic stop: In the event of a malfunction or accident, the limit switch can realize the automatic stop function to prevent accidents.

10.Safety Devices

1) Overload protection device: used to monitor the load of the crane, ensure that the equipment automatically stops when the rated load is reached or exceeded, and prevent accidents caused by overload. The sensor monitors the load weight in real time, and triggers an alarm or cuts off the power when it exceeds the set value.

2) Braking system: ensure that the crane can stop quickly and safely when it stops or in an emergency. Common braking systems include electromagnetic braking, mechanical braking and hydraulic braking.

3) Safety hook and safety lock: prevent the hanging objects from falling off during the lifting process. The safety hook is usually designed with an anti-falling device, and the safety lock will not be enabled when the hook is not fully closed.

4) Anti-overturning device: ensure that the crane will not overturn during operation. Through reasonable structural design and counterweight, instability can be prevented when lifting heavy objects.

5) Emergency stop device: in an emergency, it can quickly cut off the power supply and immediately stop all operations of the crane. The emergency stop switch should be set in a position that is easy for the operator to access so that it can be used quickly when needed.

6) Safety operating procedures: provide necessary safety training for operators to ensure that they understand the safe operating procedures of the equipment and reduce human errors. Regularly inspect and maintain equipment to ensure that all safety devices are functioning properly and improve safety.

11.Control Mode

1) Manual control: The operator directly controls the various operating mechanisms of the crane through buttons or switches on the manual control panel. Simple operation, suitable for small or short-term operations; can be quickly adjusted according to specific needs.

2) Wireless remote control: The various functions of the crane are controlled by a wireless remote control, and the operator can operate at a safe distance. Improves the flexibility and safety of operation, especially suitable for complex or dangerous working environments.

3) Wired remote control: Operate through the control line connected to the crane, and the operator inputs instructions through a handheld controller. Compared with wireless remote control, the signal is stable and not easily interfered with, which is suitable for operation in a fixed area.

4) Automated control: Automated operation is achieved through PLC (Programmable Logic Controller) or computer system, and the operation of the crane is controlled according to the preset program. Improves the accuracy and consistency of operation, suitable for large-scale and repetitive operations, and reduces interference from human factors.

5) Frequency conversion control: The speed of the motor is adjusted by the frequency converter to achieve precise control of the operating speed of the crane. It can smoothly accelerate and decelerate, improve the safety and efficiency of lifting operations, and reduce the impact on equipment.
