Basic structure and working principle of 3-ton gantry crane
Basic structure
As a compact and powerful lifting equipment, the design of 3-ton gantry crane fully considers the operation efficiency and safety. Its basic structure mainly includes the following key parts:
Main beam: As the load-bearing skeleton of the gantry crane, the main beam is usually made of high-strength steel with excellent bending strength and stability. Its length and span are customized according to the operation requirements to ensure that it can cover the entire operation area.
Outrigger: The outrigger is a key component that supports the main beam and stabilizes the entire gantry crane structure. They are usually designed to be adjustable in height to adapt to different ground conditions and working height requirements. The bottom of the outrigger is usually equipped with anti-slip pads or fixings to ensure stability during operation.
Mécanisme de levage: The lifting mechanism is one of the core components of the gantry crane, responsible for lifting the cargo from the ground to the required height. It usually consists of components such as motors, reducers, drums, wire ropes or chains. The motor drives the reducer, which drives the drum to rotate, thereby rolling up or lowering the wire rope or chain to achieve the lifting and lowering of the goods.
Operating mechanism: The operating mechanism includes lateral and longitudinal moving devices, which enable the gantry crane to move in the horizontal direction. These mechanisms are usually composed of components such as motors, reducers, wheels and tracks. The motor drives the reducer, which drives the wheels to roll on the track, thereby achieving the lateral and longitudinal movement of the gantry crane.
Electrical control system: The electrical control system is the brain of the gantry crane, responsible for controlling the coordinated work of various components. It includes components such as the operating console, controller, sensor, and protective device. The operator issues instructions through the operating console, and the controller controls the actions of various components after receiving the instructions. At the same time, the sensor monitors the equipment status in real time, and the protective device automatically cuts off the power supply in abnormal situations to ensure safety.
Working principle
The working principle of the 3-ton gantry crane is based on the principle of combining motor drive, mechanical transmission and electrical control. When the operator issues an instruction, the electrical control system receives the instruction and controls the motor to start. The motor drives the drum to rotate through the reducer, rolling up or lowering the wire rope or chain, thereby achieving the lifting and lowering of the goods. At the same time, the motor also drives the wheels of the operating mechanism to roll on the track to achieve the lateral and longitudinal movement of the gantry crane.
During the operation, the electrical control system monitors the equipment status in real time, including parameters such as motor current, voltage, temperature, and the operating status of each component. When an abnormal situation occurs, the protection device will immediately cut off the power supply to prevent accidents. In addition, the gantry crane is also equipped with a variety of safety devices, such as limiters, overload protectors, anti-slip devices, etc., to ensure safety during the operation.
In summary, the 3-ton gantry crane provides a reliable solution for small to medium-sized lifting operations with its sophisticated design and efficient working principle. Its compact structure, powerful functions, easy operation, safety and reliability make it the preferred lifting equipment in many industries.
