What is a lifting machine?
Hoisting machinery is a mechanical equipment used to move heavy objects vertically or horizontally. It is widely used in construction, manufacturing, logistics, ports and other industries. They can efficiently and safely complete the lifting, handling and stacking tasks of heavy objects, significantly improving work efficiency and reducing labor costs. This article will combine recent hot topics to introduce in detail the definition, classification, application and safety precautions of lifting machinery.
1. Classification of lifting machinery
Hoisting machinery can be divided into the following categories according to structure and function:
| type | Features | Typical application scenarios |
|---|---|---|
| Bridge crane | Across a factory or warehouse, running along tracks | Factory, workshop, warehouse |
| tower crane | Towering structure, adjustable arm length | Building construction, bridge engineering |
| truck crane | Strong maneuverability and built-in power system | Logistics, emergency hoisting |
| Gantry crane | Door-shaped structure, suitable for open-air operations | Ports, docks, yards |
| jib crane | Fixed or mobile cantilever structure | Small workshops and repair places |

3. Core technical parameters of lifting machinery
When selecting a lifting machine, you need to pay attention to the following key parameters:
| parameter | illustrate | Example |
|---|---|---|
| Rated lifting capacity | The maximum lifting weight allowed by the equipment | 50 tons |
| working range | Horizontal distance from hook center to rotation center | 30 meters |
| Lifting height | The vertical distance from the lowest to the highest position of the hook | 60 meters |
| job level | Reflects the frequency of device use (A1-A8) | A5 |
4. Precautions for safe use
Lifting machinery operations must strictly abide by safety regulations:
1.Operators work with certificates: Must obtain special equipment operator certificate.
2.daily inspection: Daily inspection of key components such as wire ropes, brakes, and limiting devices.
3.Overloading is strictly prohibited: Exceeding the rated lifting capacity may cause structural deformation or even overturning.
4.Environmental monitoring: Tower crane operations should be stopped when the wind force is greater than level 6.
5.Signal specifications: Dedicated command personnel must be equipped and unified gestures/semaphores must be used.
5. Industry development trends
According to recent industry trends, lifting machinery shows the following development directions:
1.Intelligent: Realize remote monitoring and fault warning through Internet of Things technology.
2.Greening: Electric cranes gradually replace diesel-powered equipment.
3.Modular: Quick disassembly and assembly design meets temporary engineering needs.
4.Oversize: The lifting capacity of the crane supporting the offshore wind power installation ship exceeded 2,000 tons.
Summary: As an important piece of equipment in modern industry, lifting machinery’s technological progress and safety management have always been the focus of the industry. The recent development of new energy and smart logistics has brought new opportunities and challenges to the crane industry.
